E-stim Types - NMES through low rate TENS

Question 1

goals for NMES

Answer 1

atrophy/treatment
strengthening
synchronous firing/recuitment of motor units

Question 2

“artificial” contractions stimulated by NMES

Answer 2

• more random recruitment, large and small together

- cannot alter # of motor units recruited

variation for alternating current that is interrupted and delivered in short bursts
-medium fq, burst alternating current

Question 11

shorter off time, longer the on time =

Answer 11

greater chance for fatigue

Question 12

the longer the on time =

Answer 12

decrease force output over time

Question 13
