The aim of the study is to investigate the effects of respiratory muscle strengthening and diaphragmatic breathing on pain levels, respiratory capacity and sleep quality in participants with shoulder pain and disability.
The control group will undergo shoulder rehabilitation, while the experimental group will receive shoulder rehabilitation in addition to respiratory muscle strengthening and diaphragmatic breathing exercises. Spirometric measurements will be taken before and after the treatment for both groups. Scales to assess shoulder pain levels and sleep quality will also be applied.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
After the spirometric measurements, the effects on shoulder pain levels, functionality, and quality of life will be evaluated in the experimental group. In addition to shoulder rehabilitation, respiratory muscle strengthening exercises and diaphragmatic breathing will be applied. Finally, spirometric measurements will be taken again, and the impact of respiratory muscle strengthening exercises on lung capacity will be assessed.
Other: respiratory muscle strengthening exercises and diaphragmatic breathing exercises
After the spirometric measurements, the effects on shoulder pain levels, functionality, and quality of life will be evaluated in the control group. Shoulder rehabilitation will be applied. Finally, spirometric measurements will be taken again.
Other: shoulder rehabilitation
Exercises and mobilizations aimed at reducing shoulder pain and increasing range of motion, when applicable, will be implemented. Spirometric measurements will be taken before and after the treatment.
The effects of strengthening the respiratory muscles and applying diaphragmatic breathing exercises on pain levels, lung capacity, and sleep quality will be examined in individuals with shoulder pain. Spirometric measurements will be taken.
Change in Shoulder Pain and Disability Index (SPADI) Score
Shoulder pain and disability will be assessed using the Shoulder Pain and Disability Index (SPADI). The SPADI consists of 13 items divided into two subscales: pain (5 items) and disability (8 items). The total score ranges from 0 to 100, with higher scores indicating greater pain and disability. Assessments will be performed at baseline and at the end of the three-week intervention.
Time frame: Baseline and 3 weeks after baseline
Change in Shoulder Pain Intensity (VAS)
Pain intensity at rest, during activity, and at night, measured using a 0-10 cm Visual Analog Scale. Higher values indicate greater pain.
Time frame: Baseline and 3 weeks after baseline
Change in Pulmonary Function (FVC)
Forced vital capacity measured by spirometry, expressed in liters.
Time frame: Baseline and 3 weeks after baseline
Change in Pulmonary Function (FEV1)
Forced expiratory volume in one second, measured by spirometry, expressed in liters.
Time frame: Baseline and 3 weeks after baseline
Change in FEV1/FVC Ratio
Ratio of forced expiratory volume in one second to forced vital capacity, expressed as a percentage.
Time frame: Baseline and 3 weeks after baseline
Change in Peak Expiratory Flow (PEF)
Peak expiratory flow measured using spirometry.
Time frame: Baseline and 3 weeks after baseline
Change in Shoulder Range of Motion
Active and passive shoulder range of motion measured using a universal goniometer, expressed in degrees.
Time frame: Baseline and 3 weeks after baseline
Change in Modified Constant-Murley Score
Shoulder pain, daily activities, range of motion, and strength assessed on a 0-100 scale. Higher scores indicate better shoulder function.
Time frame: Baseline and 3 weeks after baseline
Change in Western Ontario Shoulder Instability Index (WOSI) Score
The Western Ontario Shoulder Instability Index (WOSI) will be used to assess shoulder-related physical symptoms, sports/recreation/work, lifestyle, and emotional functioning. The questionnaire consists of 21 items, with a total score ranging from 0 to 2100. Higher scores indicate greater shoulder-related impairment and poorer quality of life.
Time frame: Baseline and 3 weeks after baseline
Change in Pittsburgh Sleep Quality Index (PSQI)
Sleep quality assessed using the PSQI global score, ranging from 0 to 21. Higher scores indicate poorer sleep quality.
Time frame: Baseline and 3 weeks after baseline
Change in Pectoral Muscle Shortness
Pectoral muscle shortness measured using anatomical landmark distances, expressed in centimeters.
Time frame: Baseline and 3 weeks after baseline
Change in Cervical and Lumbar Range of Motion
Cervical and lumbar range of motion measured using goniometry, expressed in degrees.
Time frame: Baseline and 3 weeks after baseline

Started Nov 2025 (actual). Primary completion is estimated for Dec 2026, 13 months after the start.
Of 349 non-industry interventional studies with no phase under Shoulder Pain, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 27. This study's planned 13 months is above that.
Counting every sponsor, half of 354 studies reached it within 11 months; a quarter within 4 and three quarters within 27.
