Purpose: This study aimed to identify whether cutaneous sensory (CS) changes induced by mechanical and electrical interventions increase the trigger point threshold of the same spinal segment. Methods: The participants were randomly divided into three groups with 10 participants each: the mechanical intervention (MI) group, electrical intervention (EI) group, and control group. Mechanical intervention was applied through Graston, and EI was applied through the transcutaneous electrical nerve stimulator for 5 min to induce CS changes. The sensory test measured CS changes using Von Frey filament and pressure pain threshold (PPT) changes estimated using an algometer. To observe changes in sensory and pain threshold with time, the test was conducted three times: pre-, post-, and 15 min post-intervention . Results: The results showed significant changes in CS in the MI and EI groups (p<0.05). Furthermore, changes in the PPT of the right infraspinatus were observed in the same spinal segment (p<0.05). Conclusion: CS changes induced by MI and EI changed the PPT in the same spinal segment. Therefore, it can be useful for pan control and for increasing the PPT in the clinical field.
