Peak Acceleration Measured in Extensor Carpi Radialis Longus Primary · Day 1

The highest acceleration over a single muscle twitch will be used as the peak acceleration. Peak acceleration will be measured in acceleration in number of times gravity (g). Higher twitch acceleration is a better response.

Time to Peak Acceleration Measured in Extensor Carpi Radialis Longus Primary · Day 1 at 2 Hz, Day 1 at 4 Hz, Day 1 at 6 Hz

The time, in seconds, until peak acceleration is reached will be assessed at 2, 4 and 6 Hz. There is not a reference range for the time to peak force and at this time it is unclear if a shorter or longer time to peak force indicates a more desirable state of health.

End Acceleration Measured in Extensor Carpi Radialis Longus Primary · Day 1

End acceleration is the twitch acceleration averaged over 5 twitches over the last second of stable twitches within the stimulation period. A reference range has not yet been established for this measurement.

Fatigue Ratio Measured in Extensor Carpi Radialis Longus Primary · Day 1

Fatigue ratio is the ending acceleration divided by peak acceleration during a given stimulation period. A reference range has not yet been established for this measurement. A higher ratio indicates less change from maximum. A lower score would indicate worse outcome.

Sponsor's own description

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.
