Our tactile senses keep us aware of our environment and are essential for the execution of natural movement. Though there have been many advances in modern prosthetic devices, the loss of sensory feedback remains an issue, and many amputees struggle with everyday movement. Lack of sensory feedback in transtibial (below-knee) amputation means that the prosthesis user must rely on their residual limb for all motor skills. Patients suffer with problems in balance control, risk of falling, and severe phantom limb pain. A University of Pittsburgh group seeks to address this need for sensory feedback in prosthetic devices.
