The Effect Of Nerve Mobilization On The Median Nerve In Pain Perception Of Electrical Stimulation

Neuromobilization is a technique which is an application of manual therapy focused on nerve fibers with a sliding and stretching mechanism. Currently, it is often used as a form of diagnosis and treatment of musculoskeletal conditions with involvement of the nervous system. Increased nerve flexibility will reduce nerve sensitivity to painful stimuli. The use of transcutaneous electrical stimulation (TENS) electric currents in conditions of nerve disorders can help eliminate/reduce pain symptoms if the area given the TENS current has normal nerve sensitivity. This study aims to determine the effect of median neuromobilization on the perception of pain from electrical stimulation in the body parts innervated by the median sensory nerve. Method: This study is an experimental research with Single Group Pretest Posttest Design. A research group with a subject of 50 people who will be measured electrical pain perception before and after being given neuromobilization. Pain perception examination was carried out by providing electrical stimulation to the left forearm using an electrical stimulation device brand BTL 4000 with a dynamic current type, constant current intensity 5Hz in 3 minutes. The instrument used to measure pain perception is the visual analog scale (VAS). Results: Hypothesis testing with the Wilcoxon signed ranks test showed a significant decrease in pain perception after neuromobilization of the median nerve to the sample with a Z value of -2,956 and a p value (Asymp Sign. 2-tailled) of 0.003 (˂ 0.05). Conclusion: Mobilization of the median nerve can significantly reduce the perception of electrical pain in the skin area innervated by the C6, C8 and Th1 spinal cord segments and the median nerve (palmar surface of the left forearm 1/3 distal and thenar area) Keywords: Median nerve mobilization, Pain perception, Physiotherapy, Neuromuscula
