Objective: To investigate the efficacy of extracorporeal shockwave therapy (ESWT) on cervical myofascial pain following neck dissection in reducing pain and improving cervical range of motion (ROM).
Methods: Forty-six patients with cervical myofascial pain following neck dissection surgery were recruited and subdivided at random into two equal groups. The ESWT group received ESWT once a week for 4 weeks (0.25 mL/mm2, 1,000 shocks) and a topical non-steroidal anti-inflammatory drug (3 times/day for 4 weeks). The control group received only topical NSAID. The pain assessment was done by using the visual analog scale (VAS) and pressure algometry. A cervical ROM device was used for the assessment of the lateral flexion and rotation of the neck ROM on both sides. All measurements were collected at baseline, 2 weeks, and 4 weeks.
Results: The ESWT group revealed a significant improvement in all parameters at post I and post II than did the control group (p>0.001), that revealed a statistical decrease only in the VAS score at post I without any statistical difference in the pain threshold and neck ROM. However, there were statistical differences in all parameters at post II compared to those at pre-treatment and post I (p<0.001).
Conclusion: As a confirmation of the efficacy of ESWT in cervical myofascial pain control following neck dissection, we observed better results with no side effects in the ESWT group (Clinical Trial Registry No. PACTR202002648274347).
