Summary

The purpose of the study is to investigate whether electrical stimulation to leg muscles and joints can help with balance in people with ankle instability. Participants will be asked to walk on a treadmill in a virtual reality cave. They will receive light electrical stimulation at the legs to improve your balance. The virtual reality image will sometimes shift in unexpected ways to challenge your balance. During the session, we will conduct a series of clinical assessments, including tests of functional performance and balance. Additionally, participants will be asked to fill out some questionnaires.

Conditions

• Ankle Sprains
• Ankle Instability

Interventions

Type	Name	Description
DEVICE	Stochastic Resonance (SR)	The system consists of six linear isolated stimulators (STMISOLA, Biopac Systems, Inc., Goleta, USA). The SR signal (Gaussian White Noise, zero mean) will be generated through a 16 bit PCI 6733 National Instruments multifunction data acquisition card by a custom LabView program. The stimulation sites include the ankle, lateral soleus, peroneus longus, and tibialis anterior muscles and the hip.
