Shock Wave Therapy On Cervical Pain Following Neck Dissection Surgery

Efficacy of Extracorporeal Shock Wave Therapy (ESWT) on Cervical Myofascial Pain Following Neck Dissection Surgery

Myofascial pain syndrome (MPS) is a musculoskeletal disorder which is characterized by pain, muscle spasms and muscle tenderness, as well as a limited range of motion, weakness, and rarely, autonomous dysfunction.

The occurrences of morbidity of the neck after cancer therapy were considerable and consisted of neck pain, loss of sensation, and decreased range of motion. Extracorporeal shock wave therapy (ESWT) is one of the treatment options used for patients with myofascial pain syndrome through elimination of ischemia and modulation of vasoneuroactive substance (two major causes of trigger pathophysiology) and mechanical transduction as a cellular response to external stimulation. the aim of this study was to investigate efficacy of extracorporeal shock wave therapy (ESWT) on cervical myofascial pain following neck dissection surgery.

Inclusion Criteria:

1. Previous unilateral modified radical neck dissection.
2. Patients with myofascial pain of upper trapezius for at least 3 months.
3. Patients with palpable intramuscular taut band.
4. Restriction in cervical ROM of lateral flexion and rotation.
5. Provocation of the clinical symptoms by compression of the active trigger point

Exclusion Criteria:

1. Patient who received medication or other therapies for MPS within the previous 2 months.
2. Patients with pacemaker, pregnancy
3. Open wound at the treatment area.
4. Cervical myelopathy or radiculopathy, cervical spine fracture or spondylolisthesis.
5. Rheumatoid arthritis.
6. Coagulopathy.
7. Epilepsy or any psychological disorder.
