Brief Summary

Rotator cuff tendinopathy, also called subbracromial impingement syndrome, is one of the most important causes of anterior shoulder pain. Although exercise training is known as an effective intervention method in the treatment of rotator cuff/subacromial impingement problems, there is no definite consensus on which type of exercise is more effective. The aim of this study is to analyze and compare the effects of the Heavy Slow Resistance (HSR) training and eccentric exercise training on pain, function, supraspinatus tendon structure, muscle strength, range of motion, subjective perception of improvement and treatment satisfaction in individuals with subacromial shoulder pain associated with rotator cuff tendinopathy.

Outcome Measures

Primary Outcomes (1)

  • The supraspinatus tendon thickness and elasticity

    Affected party the supraspinatus tendon thickness and elasticity value will be evaluated by shear-wave elastography by a specialist radiologist.

    6 weeks

Secondary Outcomes (4)

  • Isometric muscle strength

    6 weeks

  • Shoulder range of motion

    6 weeks

  • The level of pain and disability associated with the shoulder

    6 weeks

  • Shoulder pain severity

    6 weeks

Study Arms (2)

Heavy slow resistance group (HSR group)

EXPERIMENTAL

The investigators are planning a 6-week rehabilitation program, 2 days a week. The same physiotherapy and home exercise program will be applied to both groups. The physiotherapy and home exercise program will include patient education, stretching, range of motion and posture exercises. Resistance training will consist of different exercise principles but the same types of exercises. Resistance training: Dumball will be used as exercise equipment. Exercise intensity determined using the Numerical Pain Rating Scale (NPRS). Individual loading will be made according to the amount of weight. The maximum amount of pain producing pain less than 4 on the Numerical Pain Assessment Scale will be determined as exercise intensity. It will include 3 different exercises: 1) Full can. 2) External rotation in side lying. 3) Internal rotation in side lying.

Other: Heavy slow resistance training

Eccentric exercise training group (EE group)

ACTIVE COMPARATOR

The physiotherapy and home exercise program will include patient education, stretching, range of motion and posture exercises. Resistance training will consist of different exercise principles but the same types of exercises. Resistance training: Dumball will be used as exercise equipment.

It will include 3 different exercises: 1) Full can. 2) External rotation in side lying. 3) Internal rotation in side lying.

Other: Eccentric exercise training

Interventions

Patients will perform the exercises in the concentric and eccentric phases with the maximum amount of weight tolerated at a rate of 3 seconds/repetition. The number of sets\*repetitions is given below. 2-3 minutes rest between sets will be given. 1st week 3\*15 2-3.week 3\*12 4th-5th week 3\*10 6th week 3\*8

Heavy slow resistance group (HSR group)

Among the patients in the eccentric exercise group, only the eccentric phase of the exercises in the HSR group, will be asked to actively engage with the affected party. The eccentric contraction rate will be set to 6 seconds. Each exercise will be done 3 sets of 15 repetitions. In the next week, progress will be made in exercise intensity according to tolerance and 500 g will be added to the previous weight. will be continued. If patients cannot tolerate the new weight or there is an increase in pain, the same weight will be continued for another week.

Eccentric exercise training group (EE group)
