NMES and Chronic Ankle Instability

NCT04322409 · Status: UNKNOWN · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 26

No results posted yet for this study

Summary

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.

Conditions

  • Chronic Ankle Instability

Interventions

DEVICE

Neuromuscular Electrical Stimulation

5 sessions that consist of NMES over the peroneus longus muscle. This consists of a biphasic current with a phase duration of 240us delivered in a frequency of 75 pules per second, with a ramp-up time of 2-seconds, followed by a 50-s rest period (no stimulation). Each cycle will consist of 10 seconds of "on" time, and 50 seconds off, with 10 cycles being performed each session.

DEVICE

Transcutaneous Electrical Nerve Stimulation

5 sessions that consist of 11-minutes of TENS over the skin of the peroneus longus. This consists of a biphasic current will be continuously applied at 100 pulses per second, with a phase duration of 100us for 10 minutes. The intensity will be turned up until the point the subjects feel the current (sensory threshold)
