Acupoint Stimulation Physical Therapy (ASPT) is a therapeutic technique that adjusts muscle tone through pressure stimulation of acupoints. This study compared the effects of ASPT suppression techniques on excitability changes in spinal motor neuron function in healthy participants, using pressure stimulation intensity at LU5 set at 30% and 100% of the pain threshold. The objective of this study was to examine differences in spinal motor neuron excitability between ASPT suppression techniques applied at 30% intensity relative to pain threshold and those applied at 100% intensity relative to pain threshold. Results showed that at 100% of the pain threshold intensity, the relative amplitude F/M ratio decreased significantly at 10 and 15 minutes compared to during the pressure stimulation, but no difference was observed at 30% of the pain threshold intensity. These results suggest that at 30% of the pain threshold intensity, the inhibitory effect following pressure stimulation cannot be expected. Therefore, when performing ASPT suppression techniques clinically, it is necessary to perform them at 100% of the pain threshold intensity.
