The Problem:
For injuries to the hamstring, assisted rehabilitation via brace or other supportive device is not currently available. This is problematic because every time a person with an injured hamstring moves, the hamstring is expanded and contracted without support. This puts a strain on the muscle group and impedes the healing process. Conventional rehabilitation involves wrapping the entire thigh with an elastic wrap to provide compression and increase blood flow; however, it does not reduce stress when the hamstring contracts. Furthermore, the tension of the wrap is perpendicular to hamstring tension.
The Solution:
Researchers at the University of Alabama have developed an assistive device for hamstring rehabilitation that acts as an external hamstring muscle group by using elastic bands. The device is composed of a waist belt that can be connected to shoulder pads, three rubber straps, and a knee sleeve. The bands mimic the angles and forces associated with the hamstring, which serves to reduce the contractive force of the muscle. This process reduces hamstring stress and likely speeds recovery from a hamstring injury.
