A Novel Device to Improve Mobility with Lower-limb Prostheses

Want to help individuals with lower-limb amputation improve mobility? Consider participating in our study!


We are currently developing a wearable biofeedback system for use with lower-limb prostheses. Once developed the biofeedback system could serve as a training tool for lower-limb amputees to improve gait and balance. This study aims to help us better understand how to design such device.

Each participant will attend two 1-hour sessions at Holland Bloorview Kids Rehabilitation Hospital. During the experiments, you will be wearing a “mock socket” with small vibrating motors on your thigh. You will be instructed to react to vibration, flex and extend your right knee.

Who can participate

We are looking for able-bodied adults to participate in our study. To participate for this study, you must be above the age of 18, have no significant skin damage on your right thigh, be able to fully flex and extend your right knee, have no neurological disease that affects your reaction, have a thigh circumference that fits our mock socket, and be able to communicate in English.


Ongoing until recruitment is completed.
