Accelerometer Motion to Measure Muscle Fatigue in Critically Ill Patients
In Brief
A clinical study evaluating Clinical Electrical Stimulator for ICU Acquired Weakness. Completed, enrolled 22 participants across 1 site.
Detailed Summary
The goal of this study is to develop a non-invasive test to diagnose intensive care unit (ICU) acquired weakness that can be administered to both responsive and non-responsive patients. Study participation will involve the measurement of muscle fatigue during a single 30 minute session. Skeletal muscle will be stimulated with an FDA approved clinical electrical stimulator and accelerations will be passively recorded with an accelerometer.

Timeline
Interventions
Conductive electrodes will be on the skin at each end of the tested muscle(s). Each subject will have two target muscle groups tested (extensor carpi radialis longus, and tibialis anterior). Each muscle will be stimulated at three separate stimulation frequencies (2 Hz, 4 Hz, and 6Hz) over 3 minutes each, for a total of 9 minutes of stimulation per muscle. The clinical electrical stimulator will deliver mild electrical stimulations to the muscle (20-100 mA).
