Abstract

Purpose: The purpose of this study was to compare the effects of new exercises (combined cervical and thoracic extension exercises) with those of conventional cervical extensor strengthening exercises (sitting cervical extension exercises) and thoracic extensor strengthening exercises (prone thoracic extension exercises). Method: Fifteen healthy subjects performed sitting cervical extension exercises, prone thoracic extension exercises, and combined cervical and thoracic extension exercises. During each exercise, electromyography was used to measure muscle activity in the erector spinae with C4 and T4 levels. The measured data were analyzed using one-way repeated analysis of variance. Results: With different exercises, there were significant differences in activity in the erector spinae muscle (p < 0.05). The activity in the erector spinae muscle increased significantly during the combined cervical and thoracic extension exercises compared to the sitting cervical extension (p < 0.05) and prone thoracic extension exercises (p < 0.05). The sitting cervical extension exercises significantly increased activity in the cervical erector spinae muscle compared to the prone thoracic extension exercises (p < 0.05). Activity in the thoracic erector spinae muscles was significantly increased during the prone thoracic extension exercises compared to during the sitting cervical extension exercises (p < 0.05). Conclusion: These findings suggest that the newer exercises effectively increase activity in the cervical and thoracic extensor muscles.
