Ergonomic Wheelchair Wheels

Traditional manually powered wheelchairs require the occupant to turn the chair’s rear wheels with a pushing action. This places a lot of stress on muscles that aren’t really designed to be used in this way, resulting in everything from repetitive stress injuries and muscle pain to torn rotor cuffs, joint degeneration and carpal tunnel syndrome. To combat this, Salim Nasser of Merritt Island, Florida, has taken a backward approach and developed the Rowheel System, which allows a pulling motion to translate into forward motion of a wheelchair. This transfers loads and stresses usually placed on weaker shoulder and arm muscles onto more capable muscles in the upper back, shoulders and arms to reduce the chance of injury and give the user an overall increase in endurance and range.
