TheraTryke combines upper and lower body exercise for paraplegics. Students at Calvin College in Grand Rapids, Michigan have designed and prototyped a device they’re calling the TheraTryke. TheraTryke combines upper and lower body exercise for paraplegics.

TheraTryke is not to be confused with TheraTrike which is a company specializes in designing and manufacturing therapeutic tricycles and accessories for children with cerebral palsy and similar special needs.

TheraTrykeThe objective of this project is to design and build a therapeutic trike for those with little to no use in their legs. The trike will have the capability of pumping the legs via energy transferred from hand pedaling. This device will have therapeutic benefits that no other outdoor trike on the market currently has.

Aimed at those with MS, spinal cord injuries, or complete paraplegics, it lets riders use their hands, feet or a combination of both together to propel themselves forward. Theratryke’s design diverts about a third of the pedaling power to moving the legs. Each brake lever controls both brakes. Theratryke uses a Shimano Nexus 7 gearing system that enables continuous gearless ratio changes. The trike will be trialed at a local hospital before they move forward with any manufacturing and marketing. Similar combo-pedal bikes for able-bodied riders include the Varibike and the Raxibo.

They have a Facebook page, but no website that I can find.
