简要总结
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.

结局指标
主要结局
diaphragm thickness
时间窗: before and after the 8 weeks of inspiratory muscle training
The thickness of the diaphragm will be measured using ultrasound, with a Toshiba Xario 100 ultrasound machine. Image acquisition will be performed by a physiotherapist experienced in musculoskeletal ultrasound. A linear probe (Toshiba PLT-805AT) with a frequency range of 8 to 12 MHz and a 54 mm probe footprint will be used to perform transcostal measurements at rest and in the supine position, using the B-Mode of ultrasound imaging (preset at 3 cm depth, 12MHz frequency, 64 gain points, 64 dynamic range points, and a single focus point located at 2 cm depth). Bilateral transcostal images will be obtained with the linear probe placed perpendicular to the last intercostal space, allowing for adequate visualization of the diaphragm without invasion of lung tissue during normal breathing
次要结局
- shoulder pain through VAS(before and after the 8 weeks of inspiratory muscle training)
- Upper trapezius, levator scapulae and middle deltoid pain pressure threshold(before and after the 8 weeks of inspiratory muscle training)
- maximal inspiratory pressure(before and after the 8 weeks of inspiratory muscle training)
- The Shortened Disabilities of the Arm, Shoulder, and Hand Questionnaire (QuickDASH)(before and after the 8 weeks of inspiratory muscle training)
