Exploring Coracohumeral Ligament Elasticity Changes With Matrix Rhythm Therapy in Idiopathic Adhesive Capsulitis: A...

Idiopathic adhesive capsulitis is a complex pathology that combines inflammation and tightness of the ligamentous and capsular structures in the shoulder joint. Using methods like mobilization, strengthening exercises, and stretching modalities, physiotherapy is still the mainstay in treating adhesive capsulitis. However, novel treatment modalities are being used in various musculoskeletal conditions. This case study investigates the effectiveness of matrix rhythm therapy (MRT) in treating a 42-year-old female patient with idiopathic adhesive capsulitis by examining the elasticity of the coracohumeral ligament (CHL). The patient received six sessions of MRT over two weeks, in addition to stretching exercises for the CHL and capsular tissues. The modality's effectiveness was recorded using a universal goniometer for measuring the range of motion, the Numeric Pain Rating Scale (NPRS) to measure pain, and elastography to measure CHL thickness. Significant improvement in pain and range of motion was noted. Additionally, ultrasonographic evaluations revealed a substantial reduction in thickness from 1.9 mm to 0.9 mm and in CHL shear ratio from 2.94 to 0.40. MRT has shown a beneficial effect on CHL elasticity, which helped in the case of idiopathic adhesive capsulitis, showing a possibility as a viable technique for addressing deeper tissue involvement in shoulder disorders.
