Abstract
This study investigated the effects of inhibitory techniques in acupoint stimulation physical therapy (ASPT) based on individual differences in the excitability of the spinal motor neuron function at rest. ASPT inhibition techniques were applied to 19 healthy participants during a 25% MVC pinch movement, and the excitability spinal motor neuron function was evaluated using F waves. Individual differences in ASPT inhibition effects were examined by analyzing the correlation between resting F/M amplitude ratios and the reduction in F/M amplitude ratios after the pinch movement. The higher the amplitude of the resting F/M ratio, the greater the reduction in the F/M ratio immediately after ASPT (rs=0.75, p < 0.01). It has been reported that there are individual differences in the excitability of motor neuron function, and it has been shown that individuals with high resting excitability are sensitive to inhibitory effects. Therefore, in this study, the results showed that the higher the resting excitability of spinal motor neurons function, the greater the inhibitory effect of ASPT.
