Abstract
This chapter presents an experimental study to discuss the role of reflexes during functional activity. The time from initiation of the task to the resulting electromyographic activity is measured to determine the tendon reflex latency, the functional stretch reflex latency, and the voluntary response time in human lower limbs. The tendon reflex time is measured as the shortest latency electromyographic event following impact on the muscle's tendon. Because the functional stretch reflex (FSR) is reported to be observable only in the presence of a small voluntary contraction, the voluntary response time is also measured in the presence of several steady, initial contraction levels. The spread in data is typical for all subjects studied. The mean value of all the trials at each initial contraction level shows a decreasing voluntary response time with increasing initial contraction level. This is generally true in all subjects, but the change in EMG latency at zero initial contraction with respect to 10 nm of initial torque is more prevalent in some people than in others.
