Background: Changes in joint positions have been reported to affect nerve mobility and adaptability. Purpose: To investigate the influence of different ankle positions on tibial nerve conduction velocity. Methods: This study was conducted on sixty healthy participants from both sexes. Tibial nerve motor distal latencies were recorded from different ankle positions (neutral, 20 ankle dorsiflexion and 40 ankle plantar flexion) Results: showed a significant effect for ankle positions in motor distal latency of both lateral and medial branches of tibial nerve in favor of neutral ankle position compared with other positions Plantar flexion and dorsiflexion, the mean values of motor distal latency of both lateral and medial branhes for neutral ankle position were (4.62± 0.87, 4.57± 0.89) respectively, plantar flexion were (5.06± 0.81, 5.24 ±0 .83) respectively, and dorsiflexion were (5.64± 0.92, 6.03 ± 0.93). Conclusion: Ankle neutral position is the most convenient position for assessing tibial nerve conduction velocity and it is the most appropriate position for reduce tibial nerve entrapment, while prolonged ankle dorsiflexion should be avoided to redue risk of tibial nerve entrapment
