CLINICAL NEUROPHYSIOLOGY AS AN OBJECTIVE AID FOR EVALUATION OF LIMB DISABILITY

Background: Weakness or paralysis underlying disability of limb may be due to damage to upper motor neurons, lower motor neurons, the neuromuscular junction or the muscle. Aim & Objectives: To find out the neuropathies and frequencies of particular nerve involvement in limb disability as well as to compare and find out the level of significance of the change in latency, duration, amplitude and conduction velocity of CMAP/SNAP of affected nerves. Methods: This is observational study which includes 692 patients coming to nerve conduction study OPD referred from Institutional disability evaluation board. Patient’s age, sex, height and weight were recorded. Nerve conduction study test was carried out for motor and sensory nerves. Statistical analysis was done using paired and unpaired T tests. ‘p’<0.05 (*) denotes that difference is statistically significant and ‘p’<0.01 (**) denotes highly significant difference. Results: Significant (‘p’<0.01) reduction in amplitude, duration and conduction velocity of CMAP/SNAP of most of the nerves was seen. Significant (‘p’
