Dr. stephen d. perry, department of kinesiology & physical education page 2 faculty of. Peak to peak amp notebook example: distance of soleis = 0. 2: distance of sol to spinal cord is 1. 2, time = 0. 2 s, t2 = 0. 8 s, onset time, v = d/t = 0. 2/0. 2 = 1 m/s, v = 1. 2/0. 8 = 1. 5 m/s. Clinical uses of emg: latencies and nerve conduction velo, latency is bt nerve stim and muscle resp, burst/trigger when signal is sent. Fatigue is indicated by shift to lower freq (s)
