ABSTRACT
Background: The intensive physical regimen followed by throwers and archers can impose stress on the elbow and hand in particular positions, which may increase the risk of developing peripheral nerve disorders and symptoms like pain and numbness. Purpose: The purpose of the study is to investigate the effect of forearm and elbow joint positions on ulnar nerve conduction velocity in throwers, archers, and non-athletes. Method: Total 34 subjects both males and females were included with body mass index (BMI) between 18.5 and 24.9 kg/m2. Nerve conduction study (NeuroStim NS2 EMG/NCV/EP System) was used for measuring ulnar nerve conduction velocity (NCV) across elbow joint at different angles (0° elbow extension, 45°, 90°, and 120° elbow flexion) with different forearm positions. Result: Repeated Measure Analysis of Variance (RMANOVA) revealed that there was a statistically significant difference in mean values of ulnar NCV at different angles, forearm positions & groups (p < .05). Conclusion: The forearm and elbow positions can have a significant impact on ulnar NCV, especially in athletes who perform repetitive upper limb motions. Results showed that the archers had significantly slower NCV than throwers and non-athletes at 90° of elbow flexion and forearm pronation.
