Inspiratory Muscle Training on Diaphragm Thickness, Inspiratory Muscle Strength and Shoulder Pain in Tennis Player
Spain40 participantsStarted 2025-11-01
Plain-language summary
Shoulder pain is one of the most common musculoskeletal conditions among athletes and sports enthusiasts who engage in overhead sports, and it can be highly disabling. Since the shoulder is one of the joints with the greatest range of motion in the human body, it is important to seek strategies that address trunk stability comprehensively to achieve full and effective joint mobility. The central role of the diaphragm in trunk stabilization has been the subject of research for over 50 years, although the exact mechanisms are still not fully understood.
The objective of this study is to assess the effects of inspiratory muscle training on diaphragm thickness, inspiratory muscle strength, and shoulder pain in adult tennis players with non-specific shoulder pain.
This is a single-blind, randomized controlled clinical trial. The intervention will last for 8 weeks. Patients with non-specific shoulder pain will be randomly assigned to one of two groups. The experimental group will undergo specific inspiratory muscle training, while the control group will receive no specific training intervention. Measurements of diaphragm thickness, inspiratory muscle strength, and shoulder pain will be taken before and after the intervention.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* tennis player who suffered from inespecific shoulder pain
* training at least two times per week
* Have experienced at least 1 episode of non-specific shoulder pain in the last month
* A positive result on diagnostic tests performed: Neer Test and Jobe Test
Exclusion Criteria:
* Having taken anti-inflammatories or muscle relaxants within the last 72 hours before the study
* pregnancy
* Previous diagnosis of respiratory or neurological diseases
* Previous surgeries, fractures, and dislocations in the dominant shoulder
* Inability to follow instructions during the study
* All those for whom measuring maximum inspiratory pressure is contraindicated: unstable angina, recent myocardial infarction (within 4 weeks of the event) or myocarditis, uncontrolled systemic hypertension, recent pneumothorax, post-lung biopsy surgery of less than one week, postoperative abdominal or genitourinary surgery of less than 6 months, and urinary incontinence
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
