FAQ Accordion Test

Dynamic seating is movement which occurs within the seat and/or wheelchair frame in response to client movement and force. Dynamic components absorb force which, in turn, assists the client back to a starting position. https://www.seatingdynamics.com/2020/05/05/dynamic-seating-definition/ https://www.seatingdynamics.com/2020/08/07/quick-class-what-is-dynamic-seating/

Dynamic seating may allow movement at the hips, lower extremities and neck. The dynamic components then assist the client back to their starting position. http://www.seatingdynamics.com/2019/03/12/using-multiple-dynamic-seating-components/ https://www.seatingdynamics.com/2016/10/17/3-reasons-provide-dynamic-posterior-movement-trunk-pelvis/ https://www.seatingdynamics.com/2017/01/09/3-reasons-provide-movement-knee/ https://www.seatingdynamics.com/2017/02/22/3-reasons-allow-neck-extend/

Yes, Dynamic Backs, Dynamic Footrests, and Dynamic Head Support Hardware can be used in combination with each other. For more information, please read our blog on this topic: https://www.seatingdynamics.com/2019/03/12/using-multiple-dynamic-seating-components/

The client should be able to move the component and readily return to a starting position. If the component does not move, less resistance may be indicated. If the component moves, but does not readily return to a starting position, more resistance may be required. http://www.seatingdynamics.com/category/determining-resistance/

Some dynamic seating systems are a part of a dedicated wheelchair and cannot be moved to another wheelchair frame. Other dynamic seating is modular and is offered as separate components that provide movement at one body area. One component or several can be used on one wheelchair frame to match a client’s needs at one or more body areas. These modular components typically can be used on many types of wheelchair frames, either retrofitted or at initial delivery. Seating Dynamics components are modular. Please see our Product Compatibility Matrix: https://www.seatingdynamics.com/wheelchair-compatibility/

No. A heavy duty wheelchair frame is often recommended to reduce equipment damage due to client force and movement. Dynamic Seating diffuses client forces so that the forces are not translated to the frame itself. Dynamic Seating can be used on a wide variety of frames and protects equipment from damage without limiting frame choice to heavier options.

A client may benefit from Dynamic Seating if you are seeing any of the following:

• The client is moving seating components out of alignment.
• The client has broken seating, hardware, or the wheelchair frame.
• The client actively seeks out movement, such as rocking.
• The client is more alert or less agitated with movement.
• The client has sustained injuries from colliding with portions of the seating system or wheelchair frame with sudden force.
• The client has sustained injuries from pushing against the seating system with sustained force.
• The client is ‘standing up’ in the seating system.
• The client is extending within the seating system and moving out of alignment with the support surfaces.

If you are seeing any of these concerns, contact your local seating and wheeled mobility evaluation team and ask whether Dynamic Seating may be appropriate.

Dynamic seating has many potential applications.

• Dynamic components absorb and diffuse force, protecting the wheelchair user from injury caused by their sustained and/or repeated forces and reducing subsequent damage to the seating system and wheelchair (further client injury may occur as the result of equipment damage).
• Dynamic Seating allows movement within the seating system without loss of alignment.
• Movement provides sensory input which many clients seek out and which may decrease agitation and increase alertness.
• Dynamic seating components may improve postural control, stability, and function.

https://www.seatingdynamics.com/2020/07/28/dynamic-seating-clinical-indicators/ https://www.seatingdynamics.com/2020/08/25/quick-class-dynamic-seating-general-clinical-indicators/

As dynamic seating is often used by clients who have increased muscle tone, clients with the following diagnoses often benefit from this technology:

• Cerebral palsy
• Huntington’s Disease
• Spinal cord injury (when spasms are present)
• Traumatic brain injury
• Other diagnoses where increased tone is present

As dynamic seating is also frequently used by clients who seek out movement, clients with the following diagnoses may benefit as well:

• Cerebral palsy
• Developmental disabilities
• Sensory processing disorder (when a wheelchair is also required)
• Other diagnoses where the client seeks out movement

http://www.seatingdynamics.com/2016/12/05/why-movement-helps-people-with-brain-injuries/ http://www.seatingdynamics.com/2019/08/20/dynamic-seating-for-people-with-cerebral-palsy/ http://www.seatingdynamics.com/2019/09/30/dynamic-seating-for-persons-with-spinal-cord-injury/ http://www.seatingdynamics.com/2019/10/15/dynamic-seating-for-people-with-huntingtons-disease/

Dynamic seating is appropriate for children and adults who would benefit from movement within the wheelchair.  Please refer to “Who would benefit from using dynamic seating” above. https://www.seatingdynamics.com/2019/11/21/growing-up-in-a-wheelchair-dynamic-seating/

Clinical goals include:

• To protect the client from injury
• To protect wheelchair and seating hardware from breakage
• To maintain client posture within the seating system.
• To increase sitting tolerance and compliance
• To provide vestibular input
• To provide active range of motion
• To increase alertness
• To decrease agitation
• To increase function
• To increase strength and postural control
• To reduce active extension
• To reduce energy exertion

It is important to ensure the client can return to their starting position after activating the dynamic component. If not, the component resistance can be changed. If this is not adequate to return the client to the starting position, dynamic options may not be appropriate. It is also important to ensure the client return to an appropriate posture. For example, a client may return to the starting position after extending at the hips, but assume a posterior pelvic tilt. Individual manufacturer’s dynamic components work differently and may vary in ability to return the client to an optimal posture. Some clients may experience increased extensor tone and/or postural insecurity and anxiety in response to dynamic movement. Decreasing the amount of movement may help. Check out our blog entry for more information.

Research has been done on dynamic seating and we have a literature review available. There is also a RESNA Position Paper on the Application of Dynamic Seating available which includes an extensive literature review. More research is needed and Seating Dynamics is collecting case studies at this time. http://www.seatingdynamics.com/category/dynamic-seating-research/

Dynamic seating is a relatively new area of wheelchair seating. We have a number of resources available on this website, including links to articles, recorded webinars and a bi-monthly blog (see the Resources Tab above). You may also contact us for further information and product specific training needs.

A good place to start is to seek out a wheelchair seating evaluation with a team of clinicians and suppliers who are familiar with dynamic seating options and applications. If you can’t find resources in your area, give us a call and we will be happy to help you identify someone in your area. http://www.seatingdynamics.com/2019/04/30/evaluation-simulation-and-dynamic-seating-trials/

If the medical change has resulted in a difference in how the dynamic seating responds to the client, then re-evaluation is indicated. For example, a client who has started or changed a tone management program may require an elastomer with less resistance.

Many clients do not move as much over time but do move enough to know that the surface behind them will continue to yield. https://www.seatingdynamics.com/2021/06/07/y-client-isnt-moving-as-much-what-happened/

A client may benefit from a Dynamic Back if you are seeing any of the following:

• The back canes have bent or broken.
• The back canes are moving when the client moves (indicating these could break soon!).
• The client has bent or broken lateral trunk pads or back mounting hardware.
• The client has sustained injuries from colliding with the back or lateral trunk pads of the seating system with sudden force.
• The client has sustained injuries from pushing against the seating system with sustained force.
• The client is ‘standing up’ in the seating system.
• The client has a friction rash on their back.
• The client’s pelvis slides forward when returning to sitting after ‘standing up’ in the seating system.
• The client actively seeks out movement, such as rocking.
• The client is more alert or less agitated with movement.

If you are seeing any of these concerns, contact your local seating and wheeled mobility evaluation team and ask whether a Dynamic Back may be appropriate. The Dynamic Back may be combined with Dynamic Footrests and/or Dynamic Head Support Hardware, as appropriate.

In Dynamic Back design, two features reduce shear forces. First is the placement of the pivot point. The pivot point must be raised, ideally to a level just above the cushion surface. Second is the degree of movement. The Dynamic Rocker Back interface only opens the seat to back angle approximately 10-15 degrees. This amount of movement leads to a minimal amount of shear, allowing the client to remain in alignment with the contours of the back. By providing movement in response to force, alignment may actually be improved, and these shear forces are decreased. When a client extends within a static seating system, loss of alignment with the support surfaces, friction, and loss of position occur. When a Dynamic Back is used, the client maintains contact without loss of posture.

Currently there are over 50 different manual and power wheelchair models, the majority of all commonly used CRT wheelchairs, on which we can install a DRBi. For a full list of compatible wheelchairs, please click here . If you don’t see a brand and model listed, please contact us, we may have a solution.

Yes, we can supply a DRBi on some power wheelchairs. For a full list of compatible wheelchairs, please click here. http://www.seatingdynamics.com/2019/01/15/faq-can-dynamic-seating-be-used-on-a-power-wheelchair-yes-lets-talk-compatibility/

Yes, a DRBi is very often installed on wheelchairs which are not new. For a full list of compatible wheelchairs please click here. http://www.seatingdynamics.com/2019/05/28/dynamic-seating-a-cost-benefit-analysis/

No. A recliner back and a DRBi cannot be used together.

Yes. DRBis are used very often on tilt-in-space wheelchairs and is our most common installation. For a full list of compatible wheelchairs, please click here.

The back of the seating system must move separately from the seat in order to activate the DRBi. If the molded seating system is available in two pieces, this can be used with a DRBi. http://www.seatingdynamics.com/2016/12/19/oil-water-molded-backs-dynamic-seating-mix/

A molded back can generally be used with a Dynamic Rocker Back Interface for two reasons. First, the seat to back angle only opens approximately 10-15 degrees. This amount of movement leads to a minimal amount of shear, allowing the client to remain in alignment with the contours of the back. Second, the Dynamic Rocker Back is mounted with a pivot point that further reduces shear, again, allowing the client to remain in alignment with the contours of the back. http://www.seatingdynamics.com/2016/12/19/oil-water-molded-backs-dynamic-seating-mix/

The DRBi can be used with a wide variety of seats and backs. Most off-the-shelf backs will work, though some may be limited by mounting options. For more information about the interaction of the cushion materials and a Dynamic Back, please read this blog: https://www.seatingdynamics.com/2019/06/11/wheelchair-seating-surface-cushions-dynamic-seating/

No. Due to the necessity for strength and durability clients using a dynamic back need, the non-folding dynamic back is necessary.

Depending on the wheelchair model, installation usually takes an hour or less. The PN 6100 Back Cane Saw and Drill Jig speeds things up. https://www.seatingdynamics.com/how-to-install-dynamic-rocker-back/

PDG Mobility

The DRBi is available on this manufacturer’s order form. When ordered on-chair, the DRBi does not void the manufacturer’s warranty. When the DRBi is retrofitted to an existing PDG Mobility wheelchair, the DRBi does not void the manufacturer’s warranty, even if the back posts are cut to length as a part of installation.

Freedom Designs (operating subsidiary of Invacare)

The DRBi is available on this manufacturer’s order form. When ordered on-chair, the DRBi does not void the manufacturer’s warranty. When the DRBi is retrofitted to an existing Freedom Designs wheelchair, the DRBi does not void the manufacturer’s warranty. However, if the back posts are modified (cut to length as a part of installation), the warranty will no longer cover the actual back posts.

Invacare

The DRBi is available on this manufacturer’s order form. When ordered on-chair, the DRBi does not void the manufacturer’s warranty. When the DRBi is retrofitted to an existing Invacare wheelchair, the DRBi does not void the manufacturer’s warranty. However, if the back canes are modified (cut to length as a part of installation), the warranty will no longer cover the actual back canes.

Ki Mobility (operating subsidiary of Etac)

The DRBi is available on this manufacturer’s order form. When ordered on-chair, the DRBi does not void the manufacturer’s warranty. When the DRBi is retrofitted to an existing Ki Mobility wheelchair, the DRBi does not void the manufacturer’s warranty. However, if the back posts are modified (cut to length as a part of installation), the warranty will no longer cover the actual back posts. If new back posts are ordered from Ki Mobility at the required length, the warranty is not voided on this item.

Yes. The seat to back angle is adjustable through the wheelchair manufacturer brackets, if this is a standard or added feature. If Seating Dynamic brackets are used, the seat to back angle can be adjusted 80 – 120 degrees, depending on the base.

No, a DRBi is flush with the front of the back post.

This is dependent, of course, on the specific wheelchair frame and armrest options. With back cane attached armrest options, the armrests may be mounted too high. If this is the case, a seat mounted armrest may be more appropriate. This is more likely with a client of small stature.

Yes. New back canes need to be ordered from the wheelchair manufacturer, after which the DRBi can be installed.

The DRBi is typically maintenance free. The elastomers should be checked for wear every 6-12 months. We have an elastomer replacement kit available for order through your supplier. https://www.seatingdynamics.com/2017/05/09/elastomer-goes-flat-story-j-flattened-elastomers/ https://www.seatingdynamics.com/2021/02/08/quick-class-dynamic-seating-maintenance/

Call or visit your supplier.

The DRBi includes a range of elastomers to change the resistance without having to order more equipment. The elastomers should allow the client to move the back and then assist the client back to a starting position. The default elastomer is clear (Medium). The least amount of resistance is the Yellow (soft) elastomer. Also available is Blue (Firm) and Green (Extra Firm). If the client cannot readily move the DRBi, less resistance is required. If the client does not readily return to a starting position, more resistance may be indicated.

https://www.seatingdynamics.com/2018/02/06/much-much-choosing-resistance/ https://www.seatingdynamics.com/2021/03/01/quick-class-dynamic-seating-resistance-drbi-back/

Carrying any heavy object on the back or looped around the back canes will adversely affect the DRBi function and is not recommended. If a backpack is used, a firmer elastomer may be required to prevent movement of the DRBi soley from the backpack and instead provide movement in response to client forces. If you are still having difficulty, the DRBi may need adjustment. The supplier may need to make adjustments and/or replace worn elastomers.

The elastomers should be checked for wear every 6 months, depending on the frequency and forces applied. We have an elastomer replacement kit available for order through your supplier. https://www.seatingdynamics.com/2017/05/09/elastomer-goes-flat-story-j-flattened-elastomers/ https://www.seatingdynamics.com/2021/02/08/quick-class-dynamic-seating-maintenance/

We have an easy to follow instruction guide on how to change the DRBi elastomers. To access this guide, click here. Changing the elastomers should take less than 30 minutes.

An extra firm elastomer may not provide enough shock absorption and movement. The elastomer with the least level of resistance that still allows posterior movement and return to a starting position is optimal.

Yes, a different level of resistance can be provided on each side to match different levels of force on each side. This is usually due to trunk rotation. It is important to determine if these movement patterns are consistent. https://www.seatingdynamics.com/2018/02/06/much-much-choosing-resistance/ https://www.seatingdynamics.com/2021/03/01/quick-class-dynamic-seating-resistance-drbi-back/

The DRBi should be unlatched all the time, except when the wheelchair is being transported with the client in the chair. Unlatch the back as soon as the wheelchair and client leave the vehicle. http://www.seatingdynamics.com/2018/05/30/the-dynamic-rocker-back-interface-when-should-i-lock-it-out/

There are some instances where caregivers may use the latch feature outside of transportation including when pushing a manual wheelchair over rough terrain to prevent excessive movement or during feeding. Unlatch the DRBi as soon as possible to allow the client to benefit from the dynamic feature.

Education about the need for dynamic seating equipment and how it works is essential. A DRBi which is latched is not allowing the client to benefit from the dynamic feature.

The DRBi needs to be “un-weighted” in order to be latched or unlatched (i.e. push the back forward). If there is weight or pressure put on the DRBi, the elastomers are compressed, and the back cannot be latched smoothly. If you are still having difficulty, the DRBi may need adjustment. The supplier may need to make adjustments and/or replace worn elastomers.

Yes. The pelvic positioning belt helps to maintain a neutral pelvic position during movement. http://www.seatingdynamics.com/2017/11/15/bread-butter-dynamic-backs-pelvic-positioning-belts/

A positioning device, such as a pelvic positioning belt, is designed to maintain alignment with the support surfaces (i.e. the seat and back), provide stability and postural support and to promote function. A restraint is intended to limit movement to protect the client and/or others. For specific restraint regulations and documentation requirements to allow provision of necessary postural supports, please refer to “Positioning vs. Restraint”. http://www.seatingdynamics.com/2017/11/15/bread-butter-dynamic-backs-pelvic-positioning-belts/

Carrying any heavy object on the back or looped around the back canes will adversely affect the DRBi function and is not recommended. If a backpack is used, a firmer elastomer may be required to prevent movement of the DRBi soley from the backpack and instead provide movement in response to client forces. If you are still having difficulty, the DRBi may need adjustment. The supplier may need to make adjustments and/or replace worn elastomers.

Yes, Dynamic Backs, Dynamic Footrests, and Dynamic Head Support Hardware can be used in combination with each other. For more information, please read our blog on this topic: https://www.seatingdynamics.com/2019/03/12/using-multiple-dynamic-seating-components/

This, of course, depends on the funding source. However, with proper justification, this equipment is often approved. Please refer to our Funding webpage for more information and sample justification wording. https://www.seatingdynamics.com/funding-dynamic-seating-components/

A client may benefit from Dynamic Footrests if you are seeing any of the following:

• The footplates are no longer in the correct position. These may be drooping or rotated outward.
• The footrest hangers are bent or broken.
• The footrest mounting hardware is broken.
• The client is injuring their lower legs against the footrest hangers (i.e. banging, bruising).
• The client is injuring themselves by pushing with force through the legs. This could lead to swollen and painful knees or ankles, patellar dislocation, tendon tearing, or even bone fracture.
• The client seeks out movement, such as knee extension or a kicking motion.
• The client is ‘standing’ on the footplates, getting leverage to ‘stand up’ in the wheelchair.

If you are seeing any of these concerns, contact your local seating and wheeled mobility evaluation team and ask whether Dynamic Footrests may be appropriate. The Dynamic Footrests may be combined with a Dynamic Back and/or Dynamic Head Support Hardware, as appropriate.

Seating Dynamics footrests can move in up to three different axes:

• All dynamic footrests have telescopic movement. In other words, the footrests extend or get longer in response to force, up to 1.5”. When the force lessens, the dynamic footrest will return to its original length. The amount of the resistance can be changed by using different springs. Three springs of differing resistance are included. Using telescoping movement without knee extension is appropriate for clients who have very tight hamstrings and may slide into a posterior pelvic tilt with active knee extension.
• Dynamic knee movement allows the client to extend or semi elevate their knee up to 30 degrees. The footrests to be set at a starting point of 90, 80, 70, 60, or 50 degrees of knee flexion. Each footrest can be adjusted separately to meet an individual client’s needs.
• Another option is dynamic plantar and dorsi flexion at the ankle. This option allows approximately 10 degrees of movement in either direction. This should not be used when the client has an AFO (ankle foot orthosis), as this will not allow the ankle to move. The footplate to footrest hanger starting angle is adjustable.

https://www.seatingdynamics.com/2017/01/17/dynamic-footrest-hangers-design/ https://www.youtube.com/watch?v=acb47OSZ2MA&t=2s

In general, use of dynamic footrests that lengthen only is appropriate for clients who may lose the position of the pelvis if the knee also extends, such as clients with very tight hamstrings. If the position of the pelvis can be maintained, combining lengthening and knee extension provides more movement and active range at the knee. If the client has active ankle dorsi and/or plantar flexion, providing this option allows movement and active range at the ankle, as well. If the client wears AFOs, this movement will not be possible and so this option is not recommended. https://www.seatingdynamics.com/2021/05/06/how-to-determine-which-dynamic-footrest-movements-are-indicated-for-an-individual/

Yes, the client’s feet need to be secured using ankle and/or toe straps, “ankle huggers” or shoeholders with straps to maintain contact with the footplate and activate the dynamic footrests. Otherwise, the feet may simply move off of the footplate during movement. http://www.seatingdynamics.com/2017/12/14/peanut-butter-jelly-dynamic-footrests-securing-feet/

A positioning device, such as an ankle strap, is designed to maintain alignment with the support surfaces (i.e. a footplate), provide stability and postural support and to promote function. A restraint is intended to limit movement to protect the client and/or others. For specific restraint regulations and documentation requirements to allow provision of necessary postural supports, please refer to “Positioning vs. Restraint”. http://www.seatingdynamics.com/2017/12/14/peanut-butter-jelly-dynamic-footrests-securing-feet/

Yes. Lateral Knee Pads are available for any Dynamic Footrest with knee elevation. These pads are indicated for a client who would otherwise contact the metal surfaces of the Dynamic Footrest with the lateral knee and/or lower leg.

This, of course, depends on the funding source and is coded E0953. However, with proper justification, this equipment is often approved. Please refer to our Funding webpage for more information and sample justification wording. https://www.seatingdynamics.com/funding-dynamic-seating-components/

Currently we offer dynamic footrests for approximately 35 different models of wheelchairs. For a full list of compatible wheelchairs, please click here.

Dynamic footrests are available on some power wheelchairs, but are not available at this time for center mount applications. We are able to supply a dynamic footrest for all “side mount” style footrest hangers. http://www.seatingdynamics.com/2019/01/15/faq-can-dynamic-seating-be-used-on-a-power-wheelchair-yes-lets-talk-compatibility/

Manual or power elevating and / or articulating legrests (ELRs) are not compatible as both interventions open the knee angle. Clients with increased tone and force are able to readily move a manual ELR in extension and cannot return to a starting position. Clients with increased tone and force may not tolerate a power ELR as external force is pulling against a tight muscle. Dynamic Footrests move in response to client force and only as far as the client has active range.

The different wheelchair must have Seating Dynamics receivers. We suggest you contact us to confirm compatibility between the two wheelchairs. We are happy to speak with you to verify if current dynamic footrests can be reused or if a new receiver and/or other components are required.

Please use our online request for quote tool here.

Seating Dynamics offers a number of receivers to fit a variety of wheelchair bases and to address specific scenarios. More information can be found on the Dynamic Footrests webpage. Some receivers extend above the level of the seat pan and may require the cushion to be notched at both front corners. Please use our online request for quote tool here.

We provide a “receiver” for the footrest. This receiver mounts to the wheelchair, typically to the seat frame. Each receiver is designed for a specific model wheelchair.

Yes, the Seating Dynamics footrests will swing away (in or out) or lift out from the wheelchair by simply sliding the release button located on the outside of the receiver to the rear. Swinging inward allows the footrest to move out of the way for a transfer when there is not room to the side of the wheelchair for the traditional swing-out style of footrest hanger.

Yes, the dynamic footrests have 2.5 inches of length adjustment.

The longest dynamic footrest is approximately 19 inches from the seat pan to the footplate. Here are some factors to keep in mind:

• Specific Wheelchair Frame: This will vary depending on the type of wheelchair, as some receivers sit above, at, or below the top of the seat rail and will affect the overall length.
• Seat to Floor Height: When using the longer length dynamic footrests, the seat to floor height of the wheelchair must be considered. The dynamic footrest will extend (telescope) up to 1.5 inches. Therefore, overall length of the dynamic footrests on the wheelchair equals the leg length PLUS the 1.5” telescopic movement.
• The Dynamic Plantar Dorsi Assembly: The dynamic plantar dorsi housing adds almost 2 additional inches below the footplate, so make sure that you have 3 ½” or more of ground clearance when using this option. This must be within the available seat to floor height.
• Footrest Hanger Angle: The knee angle becomes very important to consider as a longer length can be used at a 60 degree angle than at a 90 degree angle, for example.

The shortest dynamic footrest is 6” from top of seat rail to top of footplate. The actual measurement may vary depending on the wheelchair model.

A one-piece footboard can be added to the dynamic footrests as an option. https://www.seatingdynamics.com/2018/09/28/seating-dynamics-dynamic-footrest-one-piece-footboard-demonstration/ https://www.seatingdynamics.com/2021/03/01/faqs-about-the-seating-dynamics-one-piece-footboard/

Please contact us so that we can determine the cause and instruct you on the appropriate solution.

The Dynamic Footrests are typically maintenance free. The springs and elastomers should be checked for wear every 6 - 12 months. We have spring and elastomer replacements available for order through your supplier.

The telescoping feature can be adjusted by changing a spring. The knee extension feature resistance can be adjusted by changing the elastomers. The plantar/dorsi flexion resistance cannot be changed. Please read our blog on this topic by clicking here. https://www.seatingdynamics.com/2021/04/05/quick-class-dynamic-seating-footrest-resistance/

• Telescoping movement utilizes springs which are quite durable and generally do not require replacement for wear and tear.
• Knee extension utilizes elastomers which should be checked every 6-12 months. If the client is moving into knee extension too readily, the elastomers most likely need to be replaced.
• The resistance of the plantar and dorsi flexion feature cannot be changed, however these elastomers can wear out. The resistance should be checked every 6-12 months. If the client is moving into plantar or dorsi flexion too readily or not returning to a starting position, the elastomers most likely need to be replaced.

Yes, each Dynamic Footrest can be individually adjusted to meet an individual’s needs. Client forces may be stronger on one side of the body than the other. Forces can also fluctuate throughout the day and so the resistance level may need to accommodate these variations.

Yes, Dynamic Backs, Dynamic Footrests, and Dynamic Head Support Hardware can be used in combination with each other. For more information, please read our blog on this topic: https://www.seatingdynamics.com/2019/03/12/using-multiple-dynamic-seating-components/

This, of course, depends on the funding source. However, with proper justification, this equipment is often approved. Please refer to our Funding webpage for more information and sample justification wording. https://www.seatingdynamics.com/funding-dynamic-seating-components/

Our static footrests are very durable and will maintain position even under great force. If you are working with a client who is moving their footplates out of position or damaging the footrest hanger, you should first consider absorbing and diffusing these forces through our Dynamic Footrests

• Our Adjustable Windswept upper footrest hardware is designed to accommodate increased hip adduction on one side and increased hip abduction on the other side.
• Our Adjustable Super Contracture upper footrest hardware is designed to accommodate significant knee flexion contractures. Seating Dynamics also provides adjustable plantar and dorsi flexion extensions.
• Plantar Dorsi lower extension footrest hardware is designed to accommodate significant ankle range limitations and maintain footplate position.

Yes, our Adjustable Knee upper footrest hardware provides a wider range of knee angles using hardware that is very durable and will not lose position.

Yes, our Adjustable Windswept upper footrest hardware is designed to accommodate increased hip adduction on one side and increased hip abduction on the other side. This hardware can also accommodate bilateral hip adduction or abduction.

Yes, our Adjustable Super Contracture upper footrest hardware is designed to accommodate significant knee flexion.

Yes, we do offer a one piece footboard that also flips-up for transfers. A one piece footboard provides a wider space to accommodate the feet where needed and also will not “sag” medially as many footplates tend to do over time and under force. This also prevents the feet from falling into the space between the footplates. https://www.seatingdynamics.com/2021/03/01/faqs-about-the-seating-dynamics-one-piece-footboard/

A client may benefit from Dynamic Head Support Hardware if you are seeing any of the following:

• The head support pads are moving out of alignment.
• The head support pads, or hardware are broken.
• The client is able to move into neck hyperextension.
• The client repeatedly contacts the posterior head pad with force (banging).
• The client pushes with sustained force against the posterior head pad.
• The client is rotating their head, losing contact with the posterior pad, and falling forward.

If you are seeing any of these concerns, contact your local seating and wheeled mobility evaluation team and ask whether Dynamic Head Support Hardware may be appropriate. The Dynamic Head Support Hardware may be combined with a Dynamic Back and/or Dynamic Footrests, as appropriate.

Yes, the Dynamic Head Support Hardware will move posteriorly in response to client posterior and/or rotational movement. Approximately 10 degrees of movement is available posteriorly. The resistance can be changed using different elastomers.

For a full list of compatible head pads, please click here.

Yes, the sub-occipital pad adaptor is available to support a sub-occipital pad. The sub-occipital pads are available separately from the manufacturer.

Yes, our Lateral Component Hardware supports the Stealth Products lateral swing away assemblies. These assemblies are available separately from Stealth Products and can be used to mount a lateral pad or a switch.

Seating Dynamics offers two options: First, our dynamic head support hardware will attach to any surface with a universal mounting pattern (2” x 2” or 1” x 2”). Second, a spreader bar mount is available if the universal mounting bracket will not work, dependent on the type of back used. This is width and depth adjustable. A quick release mount is available to easily remove the head support.

Our Head Support Hardware does not include the typical ball used to connect to the occipital pad. Instead, we use an adapter which attaches directly to the pad. This adapter allows for full adjustment in multiple planes, but holds position much better than a round ball. Check out our blog post for more information.

The elastomers can be switched to change the level of resistance. The hardware comes standard with Blue (medium) elastomers to provide movement and to return the client to a starting position. If more resistance is needed, Green (firm) elastomers are provided with the unit. http://www.seatingdynamics.com/2018/03/06/determining-resistance-dynamic-seating-head/ http://www.seatingdynamics.com/2018/09/04/dynamic-head-support-tilt-and-recline-resistance/ https://www.seatingdynamics.com/2021/04/29/quick-class-dynamic-seating-determining-head-support-resistance/

The elastomers can be replaced if worn and should be checked every 6 months. If the head support does not readily return to a starting position, the elastomers may need to be replaced. https://www.seatingdynamics.com/2021/02/08/quick-class-dynamic-seating-maintenance/

If the head support is moving during tilt or recline without force from the client, try a firmer elastomer. http://www.seatingdynamics.com/2018/09/04/dynamic-head-support-tilt-and-recline-resistance/

Hanging any heavy object from the Dynamic Head Support Hardware will adversely affect the dynamic function and is not recommended.

We do not offer a flip-down mount, as these tend to become loose and are not as durable. We do offer optional Removable Mounting Hardware.

Yes, you can use the Stealth Products i2i head support, as long as you order our removable mounting hardware. The angle of our hardware, depending on how the links are adjusted, allows the i2i to slip upward off of the client without the need to move the client forward or back.

Yes, the Dynamic Head Support Hardware can be locked out, preventing movement, by pulling the red knob on the right side of the base. To restore movement, simply push in the knob.

The Dynamic Head Support Hardware should be locked during transportation. It may also be helpful to lock the hardware when moving over rough terrain to prevent excessive movement. Finally, it may be helpful to lock the hardware during feeding to increase stability for the client.

This, of course, depends on the funding source. However, with proper justification, this equipment is often approved. Please refer to our Funding webpage for more information and sample justification wording. https://www.seatingdynamics.com/funding-dynamic-seating-components/

The Static Head Support Hardware is designed to replace standard hardware with highly adjustable and durable hardware that maintains position. If you are working with a client who is moving their head support out of position or damaging the head support hardware, you should first consider absorbing and diffusing these forces through our dynamic head support hardware. http://www.seatingdynamics.com/2018/10/01/maintaining-head-support-position-lets-do-the-math/
