Primary outcomes
1) In the MSM software, raw data (EMG and goniometer) were synchronized and collected at 2048 samples/s. EMG signals were amplified at a gain of × 500 and further band-pass filtered (10–1000 Hz). After each stretch, MSM identified the angle and velocity at the time of EMG onset, called the dynamic stretch reflex threshold (DSRT2) Kinematics were analyzed for performance (endpoint) and movement pattern (joint/segment) variables
