What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Shoulder blood restriction trainingBehavioural
Also called massage
Massage massage is also often used to improve the treatment of local body pain, and a large number of studies have shown that massage massage can reduce shoulder pain in the short term, restore shoulder function and improve the range of motion of shoulder joints.
| Study group | Role | What they receive |
|---|---|---|
| blood flow restriction training | Experimental | blood flow restriction training (BFRT) is a popular method of sports training. It involves the use of devices such as air sleeves or elastic bands with adjustable functions during sports training that restrict blood flow to parts of the limb, resulting in an adaptive effect similar to high-intensity training in the muscles, while actually using relatively light weights. BFRT is usually combined with light exercise, such as low-load strength training or aerobic training, to build muscle strength and muscle endurance. This training method is more friendly to patients after sports injuries ， fractures, joint surgery ， etc. It can help to train the injured area with light loads to reduce muscle atrophy and speed up recovery to restore muscle function and strength. BFRT is also commonly used by athletes in different sports to improve muscle strength and endurance while reducing weight load, helping to reduce the risk of overtraining and injury. Receives: Behavioral: Shoulder blood restriction training |
| Massage | Placebo comparator | Massage is a widely used traditional Chinese physical therapy technique, which uses massage, kneading, pushing, flicking, tapping and other techniques, as well as the use of the palm, fingertips, elbows, knees and other body parts to stimulate specific body areas or acupoints to achieve the purpose of treatment or relief of disease symptoms . Massage massage can relieve musculoskeletal pain by promoting blood circulation, relaxing tense muscles and reducing inflammation, and improve muscle elasticity and flexibility, helping to reduce muscle tension and stiffness . Therefore, massage massage is often used to improve the treatment of local body pain, and a large number of studies have shown that massage massage can reduce shoulder pain in the short term, restore shoulder function and improve the range of motion of shoulder joints .

What is being measured
The primary outcome is the main question the study is designed to answer.
Shoulder strength
In this study, a muscle force tester was used to measure the maximum force of the subjects' shoulders. During the measurement, the subjects were required to maintain supine and standing positions, and the maximum force of shoulder joint push, abduction, internal rotation and external rotation was measured in different positions. The strength test of each exercise session needs to be completed three times, each measurement interval of 30 seconds, and finally the average value of the three maximum strength values is taken.
Measured: 6week
Shoulder joint range of motion Angle measurement
The measurement of shoulder joint range of motion mainly includes measuring the range Angle of shoulder joint abduction, external rotation and internal rotation under different postures (standing posture, supine posture).
Measured: 6week
Shoulder VAS score
In this study, the quantification of shoulder joint pain was carried out using the Visual Analogue Scale (VAS) . VAS is a common tool used to assess the level of pain or discomfort, including shoulder pain.
Measured: 6week
Shoulder Constant-Murley scale
Shoulder Constant-Murley scale is a clinical evaluation tool used to evaluate shoulder function and severity of shoulder diseases, and is often used to evaluate the efficacy and rehabilitation progress before and after shoulder surgery. The scale includes assessments of shoulder joint range of motion, muscle strength, pain and function of daily living.
Measured: 6week
