Frozen shoulder: ultrasound gel or muscle exercises — which works better?

This study compares two treatments for frozen shoulder (adhesive capsulitis): applying an anti-inflammatory gel through ultrasound (phonophoresis) versus a muscle relaxation exercise technique (post-isometric facilitation). About 45 adults aged 30–40 with the second stage of frozen shoulder will receive one of these treatments or standard physiotherapy three times a week for four weeks. Researchers will measure pain, pressure sensitivity, shoulder movement, and daily function to see which approach provides more relief.
