This study compared the effects of High-Velocity Low-Amplitude (HVLA) thrust and Post-Isometric Relaxation Muscle Energy Technique (PIR-MET) on pain and shoulder mobility in patients with adhesive capsulitis. Sixty-six participants received either HVLA or PIR-MET with conventional physiotherapy for four weeks. Both treatments improved pain and range of motion, but PIR-MET showed significantly greater improvement, making it a more effective approach for managing frozen shoulder symptoms.

This study compared the effectiveness of High-Velocity Low-Amplitude (HVLA) thrust and Post-Isometric Relaxation Muscle Energy Technique (PIR-MET) in treating adhesive capsulitis (frozen shoulder). Sixty-six patients received either HVLA or PIR-MET along with conventional physiotherapy for four weeks. Both treatments improved pain and shoulder mobility, but PIR-MET showed significantly better results in reducing pain and increasing range of motion. The study concluded that PIR-MET is a more effective manual therapy technique for managing adhesive capsulitis and improving patients' functional recovery and quality of life.

Inclusion Criteria:

• Participants diagnosed with Stage II or III Adhesive Capsulitis Age between 40 and 65 years Both male and female participants Presence of shoulder pain and restricted range of motion for at least 3 months Limitation of active and passive shoulder movements, particularly external rotation Willingness to participate and provide informed consent Ability to attend treatment sessions for four weeks

Exclusion Criteria:

• History of shoulder fracture, dislocation, or recent trauma Previous shoulder surgery Neurological disorders affecting shoulder function Rheumatoid arthritis or other systemic inflammatory conditions Cervical radiculopathy or referred pain from the cervical spine Rotator cuff tear or severe shoulder instability Malignancy or infection involving the shoulder joint Participants receiving other concurrent shoulder treatments Contraindications to manual therapy or physiotherapy interventions Unwillingness to participate or inability to complete the treatment protocol

Only IPD used in the result publication will be shared

It will be available after the completion of study

De-identified participant data, including demographic details, pain scores, shoulder range-of-motion data, study protocol, and analysis information, will be available to qualified researchers upon reasonable request and approval. Access will be provided through secure electronic sharing while maintaining participant confidentiality and ethical standards.

This study was single-blinded. Participants were unaware of their treatment group allocation throughout the intervention period to minimize performance and response bias. Care providers and investigators administering the interventions were not blinded due to the nature of the manual therapy techniques.
