To assist upper extremity amputees with achieving stable grasps of cylindrical
tools, this article describes the development and testing of a prosthetic device
for recreational kayak paddling. Initial development included participation of a
non-amputee expert kayakist. Subsequent testing of the device used a
pseudo-prosthesis for testing on a non-amputee subject, followed by qualitative
feedback on the device from a unilateral transradial amputee. The device was
evaluated by exploring whether subjects could independently don the terminal
device, apply the paddle and use it in a pool and on a river. A semi-hinged, two
hemi-cylinder sleeve was designed to be fitted onto a kayak paddle. The terminal
device's frame, a second (larger) semi-hinged two hemi-cylinder sleeve, attached
the device to the prosthesis. This second sleeve had internal edges that prevent
lateral shifting. This component allowed smooth paddle rotation while preventing
lateral shift and maintaining grasp. The non-amputee subject was successful at
donning the pseudo-prosthesis and paddling. Similarly, the amputee subject was
also able to don the prosthesis and paddle using the device. The design reported
here is a viable option for fabricating a cylindrical grasp, passive function
terminal device for kayaking. It is adaptable to other cylindrical grasp
functions such as lifting an exercise weight.
