Effectiveness of Ultrasound-Guided Percutaneous Electrical Nerve Stimulation (PENS) for Patients With Post-surgical Shoulder Pain: A Randomized Clinical Trial
Effectiveness of Ultrasound-Guided Percutaneous Electrical Nerve Stimulation (PENS) for Patients With Post-surgical Shoulder Pain: A Randomized Clinical Trial
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.
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.
