Inclusion criteria
Inclusion criteria: - Experimental group: Adults diagnosed with rotator cuff tear, shoulder impingement syndrome, or frozen shoulder - Control group: Healthy adults without upper limb musculoskeletal disorders (including both age-matched and younger age groups)
Exclusion criteria
Exclusion criteria: Common Exclusion Criteria Patients with other neurological lesions such as stroke. Patients who are unable to follow instructions or have cognitive impairments severe enough to hinder understanding of the clinical trial. Students supervised by the principal investigator or affiliated researchers, and undergraduate students under 20 years old. Experimental Group Exclusion Criteria Patients who have been prescribed surgical or pharmacological treatment by a physician. If a physician prescribes surgical or pharmacological treatment before rehabilitation exercises due to the severity of the tear or disease, the effects of the muscle coordination-based rehabilitation protocol are unlikely to be observed. Patients with severe pain during shoulder movement, making rehabilitation exercises impossible. If the pain is extremely severe, it is expected that the patient will have difficulty performing exercises according to the muscle coordination-based rehabilitation protocol. Patients in the frozen stage of frozen shoulder. Patients in the frozen stage have severe stiffness and reduced range of motion, making it difficult to expect rehabilitation effects through selective muscle strengthening. Control Group Exclusion Criteria Individuals experiencing pain within the active range of motion of the upper limb joints. Presence of musculoskeletal disorders and pain may cause difficulty in repeatedly performing the exercise tasks required for muscle coordination assessment. Individuals who have undergone surgical treatment for upper limb musculoskeletal disorders. It is unclear whether normal muscle coordination patterns have been restored post-surgery, which could affect study results.
