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

The aim of this clinical trial was to demonstrate the effectiveness of the application of ultrasound-guided percutaneous nerve stimulation (US-PENS) directed at the axillary nerve and the suprascapular nerve, in patients with post-surgical shoulder pain. This is a randomized, longitudinal, prospective and quasi-experimental clinical trial in which a total of 70 patients divided into two groups; physiotherapy protocol group (n=35) and experimental group to which the same protocol was practiced and a US-PENS session was added (n=35). The intervention and follow-up period of the participants took place over 12 weeks.
