Revolutionizing the Wheelchair Footrest
The dynamic footrest provides an energy absorbing range of motion. Traditional wheelchair footrests only provide a place to park the foot and, when subjected to significant forces, may be damaged. Dynamic footrests absorb the energy transmitted by the user’s movement, protecting the client from injury and the equipment from damage as well as providing movement for therapeutic benefits.
Dynamic Footrests provide up to three types of movement – a telescoping movement, knee extension, and plantar/dorsi flexion. By providing movement in response to client movement, forces are absorbed, protecting both the client and the wheelchair frame and seating system from harm. Extensor tone is absorbed and diffused, reducing overall tone and posturing. Movement is provided, which can increase sitting tolerance, decrease agitation, and increase alertness. Finally, by providing movement within a limited range, the lower extremities may experience strengthening.
Some clients may benefit from only the telescoping feature. This client may have very tight hamstrings which limit active knee extension. The telescoping feature can still absorb and diffuse force.
Knee extension, in combination with the telescoping feature, follows the natural arc of movement which occurs when the knee is straightened.
When the lower extremity is extended, extension may be seen at the hip, knee, and even ankle (plantar flexion). The plantar/dorsi flexion dynamic movement absorbs this force at the ankle

Separate footrests capture movement in each leg during extension.
Movement at the legs diffuses tone and limits movement upward at the pelvis.
This video demonstrates the three movements available in the Seating Dynamics Dynamic Footrests.
Dynamic Footrest Specifications
The first step in using any of the Seating Dynamics footrests is choosing the correct adapter / receiver. The Seating Dynamics footrest adapter / receiver allows any of our dynamic or static footrests to be used on many different wheelchairs. Depending on wheelchair manufacturer and model, different adapters may impact the final installed footrest length
Dynamic Footrest Style
The second step is the determination of the upper leg style.
Dynamic Wheelchair Footrest
The dynamic footrest, shown above with dynamic plantar dorsi flexion, provides dynamic telescoping movement to 1.5″ and dynamic elevation to 30° with the ability to set the initial (neutral / relaxed) position in one of five positions (90°, 80°, 70°, 60° and 50°).
Adjustable Windswept Option
The windswept dynamic footrest provides the same functions with the addition of an angle adjustable joint to rotate the footrest in or out, relative to the seat rail, in 7.5° increments to accommodate a windswept tendency.
Adjustable High Pivot Option
The adjustable high pivot dynamic footrest features a 4″ raised pivot and height adjustment capable of raising the pivot point an additional 2”. This style is used with a shorter leg length and/or when seating equipment is added above the seat rail which reduces the seat rail to foot plate dimension.
Plantar/Dorsi Flexion Footrest Extension
Select either static or dynamic plantar/dorsi flexion. The extensions are available in several lengths in 1” increments, each having 2.5″ of leg length adjustment.
The static extension style offers no movement of the ankle and is appropriate for clients with AFO’s. The footplate is infinitely angle-adjustable with tools.
The dynamic extension style has ± 10° of dynamic plantar/dorsi flexion movement. The footplate is infinitely angle-adjustable with tools
The fourth step is to select the appropriate size footplate. We offer small (4×6), medium (5×8) and large (6×10) foot plates. This is determined by the length of the client’s foot, the footrest style, chair width, caster size, and seat to floor height. Our footplates are heavy duty ¼” aluminum with pre-drilled holes for mounting foot positioning accessories. All footplates used with the plantar/dorsi flexion footrest extension are infinitely angle adjustable with tools. Most clients will require ankle straps or shoe-holders to maintain contact with the footrests during extension. The footplates flip-up for transfers.
