Study Description

Brief Summary

The aim of this study is to determine and compare the effects of neuromuscular control exercises for the shoulder, and standard conservative exercise programs, which are different forms of exercise and have an important role in the treatment of partial thickness rotator cuff tears on treatment. Thus, it is aimed to compare these exercise types with different mechanisms on treatment, to determine the place of neuromuscular control exercises in treatment and whether they are more effective than conventional exercises.

Rotator Cuff Tear or Rupture, Not Specified as Traumatic Pain, Shoulder	Other: Neuromuscular Control-Based Exercise Training Group Other: Conventional Exercise Training Group	N/A

Detailed Description

Rotator cuff (RC) tear shows different symptoms or sometimes can progress asymptomatic. The most common symptoms associated with rotator cuff tears are loss of shoulder range of motion (ROM), shoulder pain exacerbated by overhead activities, nocturnal pain, shoulder dysfunction, and functional limitations. Conservative treatment is the first and most preferred procedure in the treatment of partial tears. Conservative treatment includes patient education, activity modifications, medication, and physiotherapy and rehabilitation programs. In the literature search, it is seen that the studies on the conservative treatment of partial RC tears often include open kinetic chain-weighted standard exercises and strengthening exercise types. It is seen that stabilization and proprioception-based neuromuscular control exercises of the shoulder, which have an important role in restoring neuromuscular control, which is reported to be impaired in shoulder pathologies, are included in some studies and these exercises are generally added to standard treatment. However, it is not known whether neuromuscular control exercises are more effective than other exercises in the standard rehabilitation programs as a result of the combined application of these exercises in this patient group. For this purpose, it is aimed to compare the treatment efficacy of a group consisting of neuromuscular control exercises for the shoulder and a group consisting of conventional exercises and to determine the place of neuromuscular control exercises in treatment.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Group 1 Neuromuscular Control-Based Exercise Training Group	Other: Neuromuscular Control-Based Exercise Training Group Exercises for the neuromuscular control of the shoulder will be progressed by starting with the body weight, and in the following phases, a program that progresses to exercises that will improve the dynamic stabilization, coordination and proprioception of the shoulder will be applied to train the sensorimotor system. The exercise program will be performed twice a week for 8 weeks (16 sessions).
Active Comparator: Group 2 Conventional Exercise Training Group	Other: Conventional Exercise Training Group In this group, which will mainly benefit from conventional open kinetic chain strength exercises, a strengthening exercise program will be applied by advancing from body weight to elastic bands and weights. The exercise program will be performed twice a week for 8 weeks (16 sessions).

Outcome Measures

Primary Outcome Measures

Constant-Murley Score [The Constant Murley Score assessment will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
The Constant Murley Score is a 100-point scale consisting of 15 points for pain, 20 points for daily activities, 40 points for pain-free range of motion, and 25 points for strength. High scores are positively correlated with the increased functional level. While pain and activities of daily living are evaluated by the patient, range of motion and strength are evaluated by the clinician.

Secondary Outcome Measures

The Numerical Pain Rating Scale (NPRS) [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
The levels of pain felt at rest / activity / night were measured using Numerical Pain Rating Scale (NPRS). Patients were asked to evaluate their pain status with a 10-point scale and high scores are positively correlated with pain.
Shoulder Joint Proprioception with Inclinometer [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
Proprioception of the shoulder joint is assessed by reproduction/reposition testing using an inclinometer. The patient will be evaluated by recording the difference between the angle from which the patient comes and the target angle determined.
Shoulder Joint Range of Motion (ROM) [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
The shoulder flexion, abduction, internal and external rotation ROM were evaluated with goniometer while the patient was in supine position.
Shoulder Joint Muscle Strength [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
Maximum isometric shoulder flexion, abduction, external and internal rotation strength measurements will be performed using a handheld dynamometer. During the test, while the participants were in a sitting position to measure shoulder flexion and abduction forces; for the measurement of external and internal rotational forces in the supine position, the shoulder is in 90° abduction and the elbow is in 90° flexion. For each movement, the measurements are repeated 3 times and the best measurement value is recorded.
Quick DASH (Disabilities of the Arm, Shoulder and Hand) Questionnaire [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
Quick DASH is a 11-item questionnaire that questions the activities of a person in daily life, the degree of participation in recreational activities, the symptom and psychosocial state that affects their pain, and sleep quality. The total score is at least 0 and at most 100, and the high scores are positively correlated with the decreased functional level.
Short Form 12 (SF-12) [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
SF-12 was used to assess physical and mental health-related quality of life. The total score is at least 0 and at most 100, and the high scores are positively correlated with high quality of life.
Global Rating of Change (GRC) Scale [Evaluations will be done between two time points: first time at baseline and second time after 8-weeks rehabilitation program. After treatment, "change" will be evaluated.]
Global Rating of Change (GRC) scale was used to assess the overall satisfaction levels of the patients. Patients were asked to evaluate their post-treatment status with a 5-point likert scale and high scores are positively correlated with satisfaction.
