By means of a spring algometer, the pain threshold at the path of PSC on 3 subjects with marked PSC were determined and compared with the locations devoid of it. The PSC was induced by needling or electrical stimulation at the acupuncture points. It was found that the variations of cutaneous sensations on the path of PSC are closely related to the duration and strength of the stimulations. In the early period or with weak stimuli, the variations of pain threshold were not evident. However, a rise of pain threshold was generally observed after strengthening and prolonging the stimulation.
The tactile variations on the path of PSC were also tested by light knockings and were compared with the control sites. In general, there was a hypersensitive state at the path during stimulation.
The above mentioned observations show that there are specific variations in cutaneous sensations at the path of PSC.
