Overview
A single-blind randomized clinical trial with a pretest posttest design is proposed in adults over 60 years of age with chronic shoulder pain due to rotator cuff involvement. Participants will be divided into an experimental group that will receive a multi-joint strength exercise program along with proprioceptive somatosensory stimulation plus conventional treatment for 12 weeks and a control group that will only receive conventional treatment. Assessments will be performed at the beginning and end of the intervention by measuring pain with the NPRS and BPI SF scales, psychosocial factors with PCS FABQ PVAQ and TSK 11, functional disability with the Shoulder Rating Questionnaire, sleep quality with the Pittsburgh Index, and physical function with the Back Scratch Test, goniometry and inclinometer, shoulder dynamometry, and manual grip. It is expected that the combined intervention will significantly improve pain, associated psychosocial factors, quality of life, sleep, and functional capacity of participants.
