RESUMEN
The distinct and specialized movements performed in different sports disciplines may significantly influence nerve performance, potentially affecting nerve responses and the overall function within the respective athletic activities. The purpose of this study is to find the effect of forearm supination and pronation across the elbow joint on ulnar and median nerve conduction velocity (NCV) in throwers, archers, and non-athletes. A total of 34 participants both male and females were recruited with a 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 and median NCV across the elbow joint at different angles with the forearm in supination and pronation. Repeated measure analysis of variance (RMANOVA) revealed that there are statistically significant differences in mean values of forearm positions, angles, nerves and groups (p < .05). This study illuminates distinctive NCV variations across diverse athletic groups during forearm supination and pronation movements. Pronation consistently exhibited faster ulnar NCV compared to the median nerve across throwers, archers, and non-athletes, while in supination specific joint positions revealed notable differences within sports groups and nerve function.

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.
