Investigation of effectiveness of two different kinesiotaping techniques in myofascial pain syndrome: An open-label randomized clinical trial

Abstract

Background: Myofascial pain syndrome is a regional musculoskeletal pain syndrome characterized by trigger points. Although there are widely accepted treatment modalities, there is no gold standard treatment. Kinesiotaping represents an interesting modality in the treatment of musculoskeletal disorders and attracts attention with studies emerging in the recent years, but in spite of the proposed benefits of kinesiotaping, its efficacy is still unclear, thus further studies evaluating the effectiveness of kinesiotaping are needed. Objectives: We aimed to investigate, not only the effectiveness of kinesiotaping applied with the space correction and muscle inhibition techniques (compared to the home exercise program in reducing pain and improving functional status and quality of life in female patients with myofascial pain syndrome related to active trigger points in the upper trapezius), but also to evaluate the superiority of the 2 techniques over each other. Study Design: An open-label randomized clinical trial with a parallel assignment intervention model. Setting: The physical medicine and rehabilitation clinics in Istanbul University, Istanbul Faculty of Medicine. Methods: Seventy-one female patients with the complaint of pain in the upper trapezius region, diagnosed with myofascial pain syndrome, and having at least one active trigger point in the upper trapezius fibers, were randomly assigned by a computer program to 1 of the 3 groups: kinesiotaping with the space correction technique (KSCT, n = 20), kinesiotaping with the muscle inhibition technique (KMIT, n = 24), and the home exercise program alone (control group [CG], n = 27). The patients were evaluated by the numerical rating scale for pain intensity, the neck disability index for functional status, and the 36-Item Short-Form Health Survey for quality of life in the beginning of the study and at the first, second, and sixth weeks (1-month follow-up). Results: Kinesiotaping was associated with lower pain intensity levels (P = 0.019 at the first week and P = 0.026 at the second week) and better functional status (P = 0.011 at the second week) and it was effective in increasing quality of life by improving physical functions and general health (P = 0.033 and P = 0.003 at the second week, respectively) earlier than in the CG. Role limitations due to physical factors improved in the KMIT group earlier than in the other groups (P = 0.022 at the second week). Limitations: Being performed in a limited number of female patients only, absence of a placebo group, and lack of blinded assessments. Conclusion: Both kinesiotaping methods were associated with lower pain intensity levels and better functional status and were effective in increasing quality of life by improving physical functions and general health earlier than the home exercise program. There was no significant difference between the kinesiotaping methods, except for role limitations due to the physical factors domain of SF-36 which was improved in the KMIT group earlier than in the KSCT group and CGs.
