This study aims to evaluate the effectiveness of a combined treatment approach for people with chronic shoulder pain caused by subacromial bursitis. Subacromial bursitis is a common condition that can cause pain, stiffness, and reduced ability to move the shoulder. These symptoms often interfere with daily activities such as dressing, lifting objects, or reaching overhead, and may negatively affect quality of life. In current clinical practice, corticosteroid injections are frequently used to reduce inflammation and relieve pain, especially in patients with persistent symptoms. Physiotherapy is also an essential part of treatment, helping to restore movement, strength, and function. However, it is not yet clear which type of rehabilitation program provides the best results when combined with injections. In this study, all participants receive three ultrasound-guided corticosteroid injections administered once per week. Ultrasound guidance allows the physician to accurately deliver the medication into the affected area, improving safety and precision. After the injections, participants are randomly assigned to one of two rehabilitation programs. One group performs a program based on Proprioceptive Neuromuscular Facilitation (PNF), a technique that uses specific movement patterns to improve muscle coordination, flexibility, and strength. The other group receives conventional physiotherapy, including standard exercises aimed at improving shoulder mobility and function. Participants are evaluated over time to assess changes in pain, daily function, quality of life, and shoulder movement, with follow-up lasting up to six months. The purpose of this study is to determine whether one rehabilitation approach is more effective than the other when combined with corticosteroid injections. The study aims to answer the following question: Does a rehabilitation program based on Proprioceptive Neuromuscular Facilitation (PNF), combined with ultrasound-guided corticosteroid injections, lead to better improvements in pain, function, quality of life, and shoulder mobility compared to conventional physiotherapy in patients with subacromial bursitis?

Participants in this group receive a combined interventional and rehabilitative treatment. Initially, all patients undergo a cycle of three ultrasound-guided subacromial corticosteroid injections (metilprednisolone 40 mg) administered once weekly to reduce inflammation and pain. Following the injection phase, participants complete a structured physiotherapy program based on Proprioceptive Neuromuscular Facilitation (PNF), consisting of supervised sessions aimed at improving shoulder mobility, muscle strength, coordination, and neuromuscular control through specific movement patterns and facilitation techniques.

Pain intensity measured by the Numeric Rating Scale (NRS)
Pain intensity was assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicate greater pain. Patients rated their average pain over the previous 24 hours at each timepoint (baseline and follow-up).
Time frame: Baseline, 2 weeks, 1 month, 3 months, and 6 months
Upper limb function (DASH)
Upper limb function was assessed using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, a self-reported measure ranging from 0 to 100, where higher scores indicate greater disability. Participants completed the questionnaire at baseline and follow-up timepoints.
Time frame: Baseline, 2 weeks, 1 month, 3 months, and 6 months
Health-related quality of life (EQ-5D-3L Index)
Health-related quality of life was assessed using the EuroQol 5 Dimensions 3 Levels (EQ-5D-3L) Index, ranging from values below 0 (health states worse than death) to 1 (full health), where higher scores indicate better health status. The index was derived from patient responses to the EQ-5D-3L descriptive system at each assessment timepoint.
Time frame: Baseline, 2 weeks, 1 month, 3 months, and 6 months
Perceived health status (EQ-VAS)
Perceived health status was assessed using the EuroQol Visual Analogue Scale (EQ-VAS), ranging from 0 (worst imaginable health) to 100 (best imaginable health), where higher scores indicate better perceived health. Patients self-reported their health status at each assessment timepoint.
Time frame: Baseline, 2 weeks, 1 month, 3 months, and 6 months
Shoulder Range of Motion (ROM)
Shoulder range of motion was assessed using a goniometer, measuring active movements (flexion, abduction, and external rotation) in degrees. Higher values indicate better joint mobility. Measurements were performed at each assessment timepoint.
Time frame: Baseline, 2 weeks, 1 month, 3 months, and 6 months
