Abstract

Backgrounds: Neck disorders can significantly affect an individual's quality of life and their ability to carry out daily activities and tasks. Trigger points often appear in the neck and spread to the shoulder blades and arms, causing discomfort and affecting the patient's function. Many studies have shown that pain points appear more along the muscle rows of the upper trapezius muscle, one of three muscles in the large trapezius muscle mass that runs along the cervical spine down to the shoulder blades and thoracic spine. Myofascia Pain Syndrome can occur in the trapezius muscle when there is excessive tension or the development of trigger points in the fascia. This can lead to localized pain, and limited range of motion in the affected muscle. In Vietnam, shock waves in physical therapy have been widely used, but there have not been many studies in Vietnam evaluating its effectiveness on domestic subjects, mainly based on medical evidence. of foreign countries. Objectives: Compare the pre and post-intervention change in NDI index in subjects undergoing cutaneous shock wave therapy as well as compare the difference in change in NDI index between the intervention group and the control group. Methods: Intervention study on 45 subjects diagnosed with cervical pain (M54.2) or cervical osteoarthritis (M47) with pain points in the upper trapezius muscle who came for examination and treatment at the City Traditional Medicine Hospital. HCM. The treatment group received shock wave intervention with 1500 pulses, frequency 10 Hz, energy level 120 J, and the control group received shock wave intervention with 500 pulses, frequency 5 Hz, energy level 60 J within 5 weeks. NDI index was collected in subjects before and after intervention. Results: The NDI index recorded in the study clearly showed a clear improvement in pain and function of subjects with neck and shoulder problems when the intervention group recorded an average NDI index of 12.83 ± 5.7 before intervention and after intervention is 6.58 ± 4.10 with p value <0.0001 compared to the control group whose NDI value before and after intervention is 12.38 ± 4.03 10.28 ± 5.71 with p = 0.04, respectively. The NDI score reduction we achieved in the study was 48.7%. Conclusions: The study evaluated the effectiveness of improving the pain condition of subjects with pain points on the upper trapezius muscle clearly through shock wave intervention with the recommended duration of 5 consecutive treatments in 5 months. week, the allowed intensity is 120J with 1500 shocks and frequency of 16Hz. In addition, the study also showed that shock wave intervention can help subjects improve pain and functional activities of the neck and shoulder area through improving NDI scores.
