Perineural Injection Treatment for Shoulder Pain

Résumé succinct

Shoulder pain is a common musculoskeletal condition that can lead to significant functional limitation and reduced quality of life. Conventional treatments often provide limited or temporary relief, highlighting the need for alternative approaches targeting peripheral pain mechanisms. This study aims to evaluate the effectiveness of Perineural Injection Treatment (PIT) compared to Transcutaneous Electrical Nerve Stimulation (TENS) in reducing pain and improving functional outcomes in patients with subacute or chronic shoulder pain. In this randomized controlled trial, participants are assigned to receive either PIT or TENS, in addition to a standardized exercise program. The intervention is delivered over two sessions within a two-week period. Pain intensity is assessed using the Numeric Rating Scale (NRS), and functional outcomes are measured using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. The results of this study are expected to provide evidence on the comparative effectiveness of PIT and TENS, and to support clinical decision-making in the management of shoulder pain.
