NMES and Chronic Ankle Instability
Status unconfirmed · Phase 1
Conditions studied: Chronic Ankle Instability
In brief
Chronic ankle instability is associated with changes in the nervous system that amount to increased difficulty in activating the stabilizing muscles of the ankle. Neuromuscular Electrical Stimulation involves using electricity to activate those muscles in bursts, and is commonly used to improve muscle function in those with ACL injury. This study will provide 5 treatments over 2 weeks in patients with Chronic Ankle Instability and determine if Electrical Stimulation can change neural excitability, balance, neuromuscular control, and perceived function in these individuals.

Age: 18 and older, up to 35. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Subjects will be healthy subjects between the ages of 18-35. The primary inclusion criteria for this study is the presence of chronic ankle instability (CAI). According to guidelines from the International Ankle Consortium, this means subjects will report having a history of one or more ankle sprains (the first >1 year ago), and repeated sensations of giving-way as measured by a score >10 on the Identification of Functional Ankle Instability instrument (IDFAI).
You may not qualify if…
- History of fracture or surgery to the legs
- Injury to the lower legs within 3 months prior to reporting for testing that resulted in modified physical activity.
- Currently involved in an ankle rehabilitation program.
- Failing to meet standards for the safe practice of transcranial magnetic stimulation and transcranial direct current stimulation (See questionnaire). Briefly, this includes personal or family history of seizure or epilepsy; current medication use that raises risk of seizure; implanted metal, medication devices, etc.; history of brain or heart surgery; and sensitivity of the scalp or skin.
