Abstract
Background and Purpose: Myofascial trigger points (MTrPs) are a common source of musculoskeletal pain, deficits in range of motion (ROM), muscle weakness, and autonomic phenomena. Myofascial decompression therapy (MDT) has been proposed as an effective method for treating myofascial trigger points, though little research exists to support this claim. The purpose of this case report is to describe the application of myofascial decompression therapy in the treatment of two latent myofascial trigger points as part of the initial care plan for a minor league baseball pitcher following right elbow arthroscopic surgery. Case Description: The patient was a 22-year old male baseball pitcher referred to physical therapy after undergoing elective arthroscopic surgery of his right elbow. He was chosen based on the finding of latent myofascial trigger points in his right infraspinatus and levator scapulae. The patient received physical therapy care six days a week for five weeks. The physical therapy plan of care consisted of myofascial decompression therapy, self-myofascial manipulation, manual therapy, and therapeutic exercise. A second year physical therapy student performed the initial evaluation, reassessments, and treatments of the patient, under the direction and supervision of a board certified orthopedic physical therapist. Outcomes: After five weeks of intervention, the patient demonstrated improvements in right upper extremity pain, range of motion, strength, and function, and was able to begin a return to throwing program. Latent myofascial trigger point characteristics were decreased but not alleviated. Discussion: A significant increase in right upper extremity function was observed following five weeks of myofascial decompression therapy combined with an impairment based plan of care. Myofascial decompression therapy in combination with confounding treatment variables was effective in reducing latent myofascial trigger point pain, range of motion deficits, and strength deficits in this patient. Future clinical trials are required to determine the isolated effects of myofascial decompression therapy on latent myofascial trigger points.
