Seating Dynamics Dynamic Footrests can move in up to 4 directions. First, the footrests telescope, allowing movement downward. Second, the footrests elevate, allowing the knee to extend and the foot to move forward. Third, the footplate can move into plantar and dorsi flexion, allowing ankle movement. Fourth, the footplate can rotate outward, accommodating this movement which is sometimes seen in conjunction with lower extremity extension.

How is Resistance changed on the Dynamic Footrests?

The telescoping feature provides up to 1.5” of movement and is adjusted by changing a spring. The installed default spring is Blue, which responds to 40 lbs. of force. Yellow (20 lbs.) and Green (60 lbs.) are also included in the package.

The knee extension feature uses three Blue (Firm), dog bone shaped elastomers and the resistance cannot be changed though the elastomers can be changed for wear.

The plantar and dorsi flexion resistance cannot be changed. Blue (Firm) elastomers provide up to 10 degrees of movement in either direction. These can be changed out if worn.

The rotating footplates move up to 25°. One or two springs can be installed to match an individual’s resistance level need (1 spring is installed on shipping). 

Determining Resistance and Replacement

So how do I determine if the resistance needs to be changed to best meet an individual’s needs?

For telescoping and footplate rotation Dynamic Footrest movements, if the client moves in that direction, but does not readily return to a starting position, a firmer spring (telescoping) or additional spring (rotation) may be indicated. If the client is not able to readily move in a certain direction, a softer (telescoping) or single (rotation) spring may be indicated. If the client moves with different force on either side of their body, different springs can be used in each Dynamic Footrest, as well.

The telescoping resistance can be changed by using 1 of 3 different springs. Knee extension resistance cannot be changed. The resistance of the plantar and dorsi flexion feature cannot be changed. The rotating footplate resistance can be changed by using 1 or 2 springs.

Maintenance 

The springs are quite durable and generally do not require replacement for wear and tear. The elastomers will require replacement over time. If the client begins to move the component and not readily return to a starting position, the elastomer most likely requires replacement.
