Upper Trapezius Activation During Upper Limb Neural Tension Test-1 in Asymptomatic State Level Players of M.P.-An EMG Study

Upper limb tension tension test are widely used as a tool for evaluation of upper limb and neck disorders. The purpose of this study was to ascertain upper trapezius activity during ULTT-1 and to explore its correlation with symptom intensity during test.

50 subjects (26-males and 24-females) were tested using standardized procedures for ULTT-1. The EMG activity was recorded using Myo -200 and subjective pain intensity was recorded using VAS.

The results of the study showed significant relationship between upper trapezius EMG activity and ULTT-1 in asymptomatic subjects. The results of the study also showed positive correlation between upper trapezius EMG activity and VAS score in asymptomatic subjects during ULTT-1.

It is concluded that EMG activity is escalated during progression of the ULTT-1. There was a high correlation between the EMG activity and pain intensity, suggesting a mechanism for antalgic posture during neural tension.
