Background: Approximately 50% of patients undergoing physical therapy at Sunprasitthiprasong Hospital presented with musculoskeletal diseases. Upper trapezius pain is one of the main concerns that affected the work and lifestyles of patients. Common treatments were ultrasound and hot pack. Another method of physical therapy used for pain relief was shockwave therapy (SWT). However, the use of shockwave is not widespread due to the therapeutic effect. Therefore, researchers were interested in studying the effect. Objective: To compare the therapeutic effect of treatments between the shockwave and the ultrasound on a pain scale in patients with upper trapezius pain. Method: A comparative study was performed in patients with upper trapezius pain at the Department of Physical Therapy, Sunpasitthiprasong Hospital, from January 2018 to July 2018. Patients were randomly divided into two groups of 30 patients who were treated with shockwaves therapy and ultrasound therapy, respectively. Pain scales were measured using the visual analog scale (VAS) of patients before and after treatments. Data were analyzed using percentage, mean and standard deviation, and t-test. Result: It was shown that patients had different pain score before and treatment, in which both groups had significantly lower pain levels (p < .001) after the treatment. Patients treated with shockwave therapy had mean pain scores before and after treatment of 5.901.63 and 1.83
1.64, respectively. In patients treated with ultrasound, the mean pain scores before and after treatment were 6.47
1.25 and 4.33
1.94, respectively. After the treatment, the pain scores of patients treated with shockwave therapy were significantly different from those treated with ultrasound (p < .001). Conclusion: Patients with myofascial pain syndrome of the upper trapezius, when treated with shockwaves therapy, resulted in lower pain scores. The result was the same as patients treated with ultrasound.
