Wheelchairs are durable medical devices, which are mostly controlled by moving back and forth and using the hands to turn the wheels. There are electric models where are driven by motors. Note that neither of them is driven by the feet because the lack of use of the feet is why they are in the wheelchair in the first place.
The pedal-style or leg-propelled wheelchairs were recently developed and are showing great improvements in the user’s feet and legs after using this type of chair..
