Gait Modifications and Cutaneous Stimulation

Stanford University56 enrolled

Overview

The purpose of this study is to quantify differences in joint mechanics between different types of walking in healthy individuals and individuals with knee pathology. The investigators will determine how modifying gait through feedback and/or cutaneous stimulation changes joint loading.

Interventions

Cutaneous stimulationDEVICE

A non-invasive external device that will be placed on the leg of the subject. The device consists of a sensing module to determine specific points in the gait cycle, a processor to analyze signal from the sensor, and a stimulus module to provide feedback to the subject.
