Strength Training and Proprioceptive Stimulation on Pain, Function, Quality of Life, Sleep Quality, and Psychosocial Factors in Older Adults With Shoulder Pain

"The study includes two intervention modalities. The experimental group will combine conventional treatment with a structured 12-week therapeutic exercise program, with two supervised group sessions per week (50-60 minutes), which will include proprioceptive somatosensory work, multi-joint strength exercises, and adapted specific movements. Progression will be individually adjusted based on each participant's pain tolerance, physical condition, and clinical progress, complemented by home activities and supporting educational materials.~The control group will receive only conventional treatment provided at their rehabilitation center and general guidelines on the benefits of physical activity according to WHO recommendations for people over 60 years of age."
