Proprioceptive Neuromuscular Facilitation Techniques in Patients With Adhesive Capsulitis

Study Overview
=================
Brief Summary
-----------------
Adhesive capsulitis is a condition that causes limitation of function and movement in the shoulder joint and affects many activities of daily life. The clinical indicators of adhesive capsulitis; shoulder pain and progressive global stiffness of the glenohumeral joint, night pains and accompanying sleep disturbances, joint capsule contracture, decrease in synovial fluid, abnormal changes in scapular position, functional limitation and consequently decreased quality of life. When we look at the literature, it is seen that traditional rehabilitation practices aim to improve range of motion and reduce pain caused by capsular contracture. In this context, classical therapeutic exercises consisting of stretching and strengthening, joint mobilization methods, proprioceptive neuromuscular facilitation methods are applied. However, there are limited number of studies investigating the effects of PNF techniques on pain, function and activity limitation. Therefore, within the scope of the research, it is planned to apply a traditional rehabilitation program prepared in accordance with the guidelines for one group, and PNF approaches for the upper extremity and scapula in the other group. Thus, it is aimed to examine the effects of the use of upper extremity and scapula PNF techniques on pain, function, range of motion, proprioception, quality of life, sleep and patient satisfaction compared to traditional exercises in adhesive capsulitis rehabilitation. Exercises will be applied 3 days a week for 4 weeks. Each training session will last 45 minutes. Pain, function, range of motion, proprioception, quality of life and sleep quality evaluations will be performed at the beginning of the study and at the end of 4 weeks.

Detailed Description
-----------------
Adhesive capsulitis is a shoulder pathology characterized by contracture of the glenohumeral joint capsule and progressive pain with loss of range of motion. The disease picture is generally examined in 3 phases as painful phase, freezing phase and thaw phase. It is generally characterized by pain, decreased range of motion, function, activity limitations, night pain and sleep disturbances. Sleep disturbances associated with function, activity limitations and night pain negatively affect the patients' quality of life. In the literature, the success rate of conservative treatment is shown as 90%. Conservative treatment consists of nonsteroidal anti-inflammatory drugs, corticosteroids, and therapeutic exercises. The purpose of therapeutic exercises in general; to reduce pain, increase range of motion, decrease activity limitations, increase scapulohumeral rhythm by correcting impaired shoulder joint biomechanics and improve function. Proprioceptive neuromuscular facilitation (PNF) is an exercise concept that uses proprioceptors to increase responses of the neuromuscular mechanism, range of motion and muscle activation. PNF techniques are applied to improve muscle strength, endurance, mobility, stability, coordination and neuromuscular control and can be easily adapted to daily life activities. In the literature, it is aimed to increase the glenohumeral joint movements and regulate the scapulothoracic rhythm in the rehabilitation of adhesive capsulitis. However, the number of studies in the literature comparing upper extremity and scapular PNF patterns with classical exercises targeting the glenohumeral and scapulothoracic joints is limited. For this reason, the aim of the study is to focus on the structures involved in shoulder movements in adhesive capsulitis rehabilitation as a whole, and to examine the effects of the use of upper extremity and scapula PNF techniques on pain, function, range of motion, proprioception, quality of life, sleep and patient satisfaction compared to traditional exercises in patients with a diagnosis of adhesive capsulitis.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Disabilities of the Arm, Shoulder, and Hand Questionnaire | The Disabilities of the Arm, Shoulder and Hand Questionnaire was developed to measure physical disability and symptoms of the upper extremities in people with upper extremity disorders (hand, wrist, elbow, and shoulder). It is a 30-item scale that addresses difficulty in performing various physical activities that require upper extremity function (physical function, 21 items); symptoms of pain, activity-related pain, tingling, weakness, and stiffness (pain symptoms, 5 items); or impact of disability and symptoms on social activities, work, sleep, and psychological well-being (emotional and social function, 4 items). The score ranges from 0 to 100, where 0 = no disability and 100 = most severe disability. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Shoulder Proprioception with Cybex Humac Norm II Isokinetic Dynamometer | Evaluation of shoulder proprioception will be made with Cybex isokinetic device. Measurements will be performed in 30, 60, 90º flexion and abduction and 15, 30º external rotation. For each measurement, the device will be operated 3 times in continuous passive movement (CPM) mode with an angular velocity of 60˚ / second. The patient will be asked to focus on the movement and remember the angle. The difference between the target angle and the angle reached by the patient will be recorded. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Visual Analog Scale | The Visual Analog Scale is a self-reported scale consisting of a horizontal or vertical line, usually 10 centimetres long (100 mm) anchored at the extremes by two verbal descriptors referring to the pain status. The Visual Analogue Scale is a scale in which the severity of pain is marked on a vertical or horizontal line of 0-10 cm in length. During the evaluation, in the measurement of pain intensity, 0: no pain and 10: unbearable pain will be explained to the patient. Patients will be asked to mark the level of pain they feel at rest, during activity and at night. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Shoulder Pain and Disability Index | Shoulder, Pain and Disability Index were used to evaluate the functional status of the patients. SPADI is a scale that evaluates the pain and difficulty experienced by patients during various activities. It has 2 different subscales, pain and disability. In the pain subscale, pain status is questioned during 5 different daily life activities. In the disability subscale, the difficulty experienced in 8 different activities is measured. The patient was asked to score the level of pain and difficulty between 0-10 and the values were recorded. (0: no pain, 10: worst imaginable pain - 0: no difficulty, 10: extremely difficult, need help) In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Shoulder Disability Scale | Shoulder Disability Scale will be used to assess the disability status associated with pain in the shoulder. The scale includes 16 questions about daily life activities that increase symptoms. Answers to the questions are given as yes, no or not applicable depending on whether the activity has been painful in the last 24 hours. The score is calculated by dividing the number of yeses by the sum of the number of yes and the number of no. The obtained score is multiplied by 100 and converted into a percentage value. High score is associated with increased disability. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Range of Motion Assesment | The shoulder flexion, extension, abduction, external and internal rotation openings of the patients will be measured passively and actively with the universal goniometer. Measurements will be made 3 times and the average of each measurement will be recorded. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Lateral Scapular Slide Test | The lateral scapular slide test is a method used for the assessment of dominant and non-dominant side scapular dyskinesia based on the measurement of the distance between the inferior end of the scapula and the spinous process of the vertebra in the same alignment. The difference between the two sides is measured with a tape measure when the arms are at the side of the body and in the resting position, when the hands are at the waist and when the arm is in 90º abduction. Scapular dyskinesia will be considered positive for cases where the distance between the two sides is 1.5 cm or more. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Pittsburgh Sleep Quality Index | Pittsburgh Sleep Quality Index is a self-report scale that determines sleep quality, type and severity of sleep disorder in the last 1 month. Self-report questions include different factors related to sleep quality and these factors are grouped into 7 components. These components are; It provides information on subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills and daytime sleep dysfunction. The total PUKI score takes a value between 0-21. Sleep quality of those with a total score of 5 or less is considered as healthy, between 6-10 as bad sleep, and those with a score above 10 as sleep disorder. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| World Health Organization Quality of Life Evaluation Questionnaire Short Form Turkish Version | The health-related quality of life scale was developed by the World Health Organization and aims to evaluate the overall quality of life. The scale consists of 27 questions that measure physical, mental, social and environmental well-being. Since each field expresses the quality of life in its field independently of each other, domain scores are calculated between 4-20. The higher the score means the higher the quality of life. In this study, the change that occurred during the 4-week period from the beginning will be examined. | Baseline and end of weeks 4. | 
| Global Rating of Change | It is a widely used scale to evaluate satisfaction in clinical trials, especially in global musculoskeletal problems. It aims to evaluate the effect of treatment and recovery on the patient. The difference between pre-treatment and post-treatment is evaluated on a 5-point numerical scale (-2: much worse, -1: I am worse, 0: I am the same, 1: I am better, 2: I am much better) In this study, we will evaluate patient satisfaction at the end of 4 weeks. | End of weeks 4. |
