Effect of the Upper Limb Tension Test 1 on conduction characteristics of median nerve in different sensitizers

Abstract

Background and purpose: The neural tension test is used for examination and management of upper quadrant disorders. In spite of its extensive usage and recognition in clinical practice, controversies about neurophysiological basis for sensory and motor responses to test persist. Further, the test also lacks validity. Mechanosensitivity and conduction characteristics are key issues in neural problems. The purpose of the present study is to investigate the sensitive position in ULTT1 that subjects the median nerve to excessive stress, which may increase the mechanosenstivity and conduction velocity of the nerve, which in turn will help clinically to select the particular sensitizer for the neural mobilization treatment program for effective recovery. Methodology: A total of 50 subjects aged 17-25 years were selected by convenient sampling from Lovely Professional University, India. Upper limb tension test-1 was performed on dominant side maintaining ipsilateral neck side flexion and the corresponding MNCV values were recorded using the Medicaid EMG and vice versa. Results: The data were analysed using Students‘t’ – test. Significant changes were noted in MNCV values on Contralateral neck side flexion (55.286 ± 4.174) when combined with ULTT-1compared to ipsilateral neck side flexion (51.907 ± 4.37). Conclusion: The findings of the study suggest that contralateral neck side flexion has a significant effect on conduction characteristics of median nerve during ULTT-1 than the ipsilateral neck side flexion.
