Trial Outcomes

Change in Perceived Stress Scale (PSS)

Patient reported outcomes measured by questionnaires that address adverse events and the impact of quality of life using the perceived stress scale. A 10-item questionnaire, each item scored 0 (never) to 4 (very often), full scale from 0-40, with higher score indicating higher perceived stress. the more often the person perceives stress Change in PSS at week 8 compared to baseline (NCT02107261)
Timeframe: baseline and at 8 weeks

Change in Medical Research Council (MRC) Scale

"Motor strength using a dynamometer of the finger/wrist/elbow flexors to document any treatment induced weakness.~Scale from 0-4, higher score indicates poorer health outcomes." (NCT02107261)

Change in Motor Strength Comparison

"Motor strength tested using a dynamometer to document any weakness the treatment may produce as compared to the baseline visit and 8 weeks.~Dynamometer (DYN) - is a mechanical device that measures the pounds of force that a muscle exerts, Grip - a device that measures grip strength, and finger flexors digit 2 and 3 (FF d2-3). These measures are the amount of lbs of force exert. The higher number is the highest exerted out of 3 tries." (NCT02107261)

Physician Global Perception of Change - Blinded Rater 1

The principal outcome measure was improvement in musical performance, measured by blinded rater, using physician global perception of change at post treatment compared to at 8 weeks. Categories are very much improved, much improved, minimal improved, no change, and minimal worse. (NCT02107261)
Timeframe: at visit 4 (week 8)
