The pull-based propulsion of REV Wheels is designed to minimize factors that can contribute to shoulder injury and pain in manual wheelchair users. Rowheels offers two models: The REV-HX was created for quickness and responsiveness, while the REV-LX was made to be easier to use. Rowheels says both models can strengthen shoulder and back muscles that are neglected during standard self-propulsion. REV Wheels are HCPCS coded E2227 and are covered via insurance, including Medicare, Veterans Affairs and private insurance funding.
