SENSORY NERVE CONDUCTION STUDIES OF MEDIAN & ULNAR NERVE IN NORMAL HEALTHY SUBJECTS IN BHAVNAGAR, GUJARAT.
Journal Title: International Journal of Basic and Applied Physiology - Year 2018, Vol 7, Issue 1
Abstract
Sensory nerve conduction studies (SNCS) studies have been used clinically for many years to identify the location of peripheral nerve disease in single nerves and along the length of nerves and to differentiate these disorders from diseases of muscle or neuromuscular junction. Median and ulnar nerves are two important nerves in the upper limb. Objectives: To study normal SNCS of median & ulnar nerve in normal healthy subjects & to obtain and compare SNCS parameters in different age groups. Methods: 91 normal healthy subjects of both gender, 15-65 years age were participated for SNCS parameters of bilateral median & ulnar nerve by using RMS Aleron EMG/NCV instrument & analyzed for statistical significance. Results: In right and left median nerve, mean latency, duration, amplitude, Sensory nerve conduction velocities (SNCV) were 2.28(±0.26), 2.84 (±0.79), 66.07(±28.20), 56.08(±6.40) and 2.23(±0.27), 2.73(±0.67), 85.95(±19.56), 58.99(±6.46) respectively. In right and left ulnar nerve, mean latency, duration, amplitude, SNCV were 2.18(±0.21), 2.62(±1.18), 55.32(±19.84), 51.53(±5.0) and 2.11(±0.33), 2.53(±0.71), 73.08(±26.3), 54.86 (±6.27) respectively. Conclusion: Values of SNCS of bilateral median & ulnar nerve in normal healthy subjects were established. Latency increases with reduced SNCV as age advances due to ageing effects of peripheral nervous system.
