Introduction: Cervical spondylosis is a degenerative disorder of intervertebral disk progressing with advancing age. It is characterized by pain in the neck and shoulders, and headache. Objectives: The study aimed at investigating the effect of yoga on neck muscle EMG in cervical spondylosis and pain associated with it. Hypothesis: Yoga will provide effective adjuvant therapy in cervical spondylosis patients. Materials and Methods: EMG of upper trapezius and neck disability index (NDI) were recorded in cervical spondylosis patients (n=10). Pain was evaluated by 0-10 grade visual analogue scale (VAS). Then, the patients did selective yoga techniques (Tadasana, Pranayama and Schandhachakra) for four weeks. All the variables were recorded after four-week yoga. The pre- and post-yoga data were compared by Wilcoxon Sign Ranks test. Results: Yoga decreased EMG amplitude on both sides of upper trapezius muscle during Tadasana. NDI and VAS were significantly reduced but EMG frequency showed decrement trend. In addition, the doses of the nonsteroidal anti-inflammatory drugs were reduced by >50%. Conclusion: It is concluded that four-week prescribed yogic techniques are useful as an adjuvant therapy for cervical spondylosis by reducing muscular tension and spasm possibly by correcting posture leading to better oxygen consumption in damaged tissue and reversal of abnormal bone growth.
