The Rickshaw™ Rehab Exerciser is designed for people who use a wheelchair to strengthen their arms and shoulder muscles. Stronger arms are needed for propulsion, transfer, and pressure reduction lifts. The Rickshaw™ Rehab Exerciser is ideal for in home use or at facilities under a therapistÂs supervision. Its innovative design allows users to be facing either forwards or backwards from the machine and can be used with both arms in tandem or a single arm workout by removing the crosspiece. The heavy-duty steel construction fits around the width of any standard wheelchair with ease. It is latex and silicone free and does NOT come with free weights.
