Reducing Muscle Activity when Playing Tremolo by Using Electrical Muscle Stimulation to Learn ...
summary
Uses EMS to supinator and pronator teres to induce wrist rotation and teach wrist-led tremolo; tested with 16 beginners wearing EMG on extensor pollicis longus and digitorum. Practicing with EMS lowers mean %MVC from 25.3% to 21.7% while control group moves from 38.6% to 34.5%; EMS practice is significantly better than practice without instruction and not significantly different from expert instruction. Prototype is an e-textile elbow supporter with PEDOT-PSS electrodes and participants report less fatigue.
