Developing an Affordable and Lightweight Vibro-Tactile Stimulation Device for Prosthetic Use

Amputation involves the removal of a limb, whether partially or completely, due to a range of causes such
as illness or injury. In Brazil, amputation rates have been steadily increasing, with over 50,000 cases
recorded in 2011, and lower limb amputations accounting for more than 80% of them.
Individuals with lower limb amputations face difficulties in maintaining balance and stability while walking, and depending on the extent and type of amputation, may experience functional impairments like an altered gait pattern or an increased risk of falls.
To tackle these issues, we have developed an affordable and lightweight vibro-tactile stimulation device that can aid in the rehabilitation of lower limb amputees. This device provides sensory support for prosthetic use, boosting patients’ confidence and security while walking.
By incorporating biofeedback techniques in gait training rehabilitation, we aim to enhance the quality of life of individuals with lower limb amputations. Research has shown that biofeedback, which provides sensory feedback to the brain during movement, can help improve walking patterns and reduce the likelihood of falls. The use of vibrotactile sensory biofeedback is anticipated to result in substantial enhancements in gait performance.
