The online wearable device training group trained independently using wearable sensor devices according to the 'Fugu Medical Mini Program' instructions. Training started from the 5th week post-surgery and continued until the 12th week, totaling 8 weeks, with a minimum of 3 training days per week and 50 minutes each day.

The offline traditional rehabilitation group carries out rehabilitation training under the guidance of therapists. Starting from the 5th week post-surgery and continuing until the 12th week, the training lasts for a total of 8 weeks, with at least 3 sessions per week, each lasting 50 minutes.

Patients with rotator cuff tears wear sensors and undergo training in conjunction with 'Fugu Medical'.

Use a goniometer to measure the subject's shoulder flexion, extension, adduction, abduction, internal rotation, and external rotation exercises to test the range of motion of the shoulder in each direction, with the unit in degrees (°).

For the starting position, male subjects perform a standard push-up, while female subjects perform a knee push-up, keeping their back flat. The distance between the hands is 36 inches. One hand remains in support while the other hand swings to touch the supporting hand and then returns to the starting position. Then switch the supporting hand and repeat the movement. One repetition is counted when the swinging hand leaves the ground, touches the supporting hand, and returns to the starting position. Record the number of full-effort hand touches completed by the subject within 15 seconds, and repeat the test 3 times.

The subjects were asked to make fists with both hands, placing their thumbs inside the fists. Then, the subjects were required to position one shoulder in maximum adduction, extension, and internal rotation, while the other shoulder was in maximum abduction, flexion, and external rotation, and both hands needed to be placed on the back in a smooth movement. Throughout the process, both hands remained clenched in fists. The tester measured the distance between the two closest bony prominences of the hands on the back. The test was repeated three times.

The subjects performed shoulder flexion, extension, adduction, abduction, internal rotation, and external rotation movements, resisting resistance to perform isometric contractions, and their muscle strength was measured.

It mainly assesses the functional status of the shoulder joint, with higher scores indicating better shoulder function. This includes muscle strength (25 points), pain level (15 points), ability to perform daily activities (20 points), and range of motion of the joint (40 points), for a total of 100 points. Lower scores indicate poorer shoulder joint function.
