Development and evaluation of a sensor system to monitor the stance-phase control function of the Automatic Stance-Phase Lock (ASPL) mechanism

Prosthetic Knee Sensor Development

Summary

Our lab has developed a prosthetic knee joint mechanism for above-knee amputees, it is called the Automatic Stance-Phase Lock (ASPL). The ASPL has already been tested in indoor labs with elaborate equipment. Now, we've developed  a sensor to test the knee in real-life conditions and we'd like you to help us test the sensor.

Who can participate

We are looking for able-bodied adults willing to wear a prosthetic simulator to participate in our study. To volunteer for this study, you must be above the age of 18, weigh less than 100kg (220lbs), be at least 140cm (5’ 7”) tall, be a strong, independent walker, and be able to communicate in English.

 

What's Involved

Participants will be asked to attend 2 sessions, each lasting 2 hours. The first session will involve gait training and the second will be for data collection. Participants will be asked to perform several walking trials along a 10 meter walkway. The loading and function of the knee will be recorded for our analysis using the developed series of sensors. You may feel some discomfort on your skin from the simulator, and bearing weight on your knee may result in muscle or joint stiffness.

All sessions will take place at Holland Bloorview Kids Rehabilitation Hospital. Participation in this study is voluntary and participation will not affect relationships with Holland Bloorview or the University of Toronto.

Deadline

Ongoing until recruitment is completed.
