Problem:Question: Is the pain-induced decrease in low-threshold motor unit discharge rate associated with the amount of increase in spike-triggered average torque?
Answer: The pain-induced modifications in the estimated motor unit twitch torque (1) were not caused by changes in muscle fiber action potential, and (2) were not associated with the decrease in discharge rate.
Solution:
no
