Effectiveness of Ultrasound-Guided Nerve Stimulation for Patients With Post-surgical Shoulder Pain

The objective of this clinical trial is to evaluate the effects of including ultrasound-guided percutaneous nerve stimulation (US-PENS) on the suprascapular nerve and axillary nerve, along with a manual physical therapy protocol in patients with pain and lack of function after a shoulder surgery. Methods: 70 patients with shoulder pain undergoing arthroscopic surgery were recruited. They were divided into two groups at random; physiotherapy protocol group (n=35) and experimental group to which the same protocol was practiced and two sessions of US-PENS were added (n=35). A series of variables were evaluated: Pain, disability and functional impotence with the help of the NSPR, SPADI and DASH scales. In turn, goniometry, dynamometry and calculation of the pressure pain threshold were performed. The intervention and follow-up period of the participants lasted 12 weeks.
