Summary

Subacromial Impingement Syndrome (SIS) is one of the musculoskeletal system problems. SIS, which is the most common cause of shoulder pain, constitutes 44-65% of complaints of shoulder pain. Studies have shown that exercise is effective in treating patients with SIS, but the effectiveness and superiority of Neuromuscular Electrical Stimulation (NMES) to each other is uncertain. NMES is widely applied in physiotherapy. In the SIS, the lower trapezius and serratus anterior muscle are affected. Therefore, our aim is to determine the effects of exercises and NMES used in patients with SIS on pain, range of motion (ROM), muscle strength and functional status, neck pain and sleep quality.

Detailed description

The aim of this study investigate exercise training (ET) and ET combined with Neuromuscular Electrical Stimulation (NMES) on pain, range of motion (ROM), functional capacity, neck pain, sleep quality. The study will be included 48 volunteers with Subacromial Impingement Syndrome (SIS). The study's inclusion criteria are as follows: Having a diagnosis of subacute / chronic extrinsic SIS, 18 to 65 years of age and being volunteer. The exclusion criteria are as follows: Fracture or surgical history in the shoulder region, another diagnosis that can affect shoulder function, having received local corticosteroid injection / treatment in the shoulder joint within the last 3 months, neuromuscular disease, pregnancy, cancer, unstabil angina, communication problems, systemic inflammatory joint disease, situations where electrical stimulation and exercise are contraindicated, orthopedic, rheumatologic or congenital disease of the affected upper extremity. The sociodemographic data of the patients will be questioned. ET will be applied daily and NMES will be applied 2 days a week for 8 weeks. In addition, both groups will apply these exercises as a home program 3 times a day, 10 repetitions of each exercise. Pain intensity with Visual Analog Scale (VAS), range of motion (ROM) with goniometer, muscle strength with Hand-held Dynamometer, upper extremity function evaluation with Quick Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire, disability of neck level with Neck Disability Index, sleep quality with Pittsburgh Sleep Quality Index will be evaluated before and after treatment. All parameters will be compared between ET and ET+NMES group.

Interventions

Type	Name	Description
PROCEDURE	Neuromuscular Electrical Stimulation (NMES)	In Neuromuscular Electrical Stimulation (NMES) application, 4 surface electrodes will be placed in the swollen part of the lower trapezius and serratus anterior muscles of each patient. NMES will be applied for 20 minutes in rehabilitation mode with a 4-channel device. Frequency: 80 Hz Amplitude: 0-100 mA (0-0.01 V) Current time-Pulse: 200 μsec Wave form: Biphasic Cycle time: 8 seconds of tetanic muscle stimulation for all patients, with a 2 second rise and fall time and stimulation It will be set as 3 seconds between. It is important to visually observe the contraction to determine the intensity of stimulation.
PROCEDURE	Exercise Training (ET)	Patients will do Wand exercises under the supervision of a physiotherapist. Wand exercises will include shoulder flexion, external rotation and abduction in the scaption position. In the first and second week, these exercises will be performed on the back, and from the third week on standing exercises. Exercises with the Theraband will be done in 3 sets, each set will consist of 10 repetitions. There will be a 1 minute rest period between sets. When the three sets are easily completed and there is no reported fatigue by the patient, the resistance will be increased by moving from yellow to red, from red to green, respectively, after 4 weeks. \*For shoulder external rotators and serratus anterior muscles are strengthened without weight for the first 2 weeks, then 0.5 kg of dumbbells, in the supine position. While standing, the lower trapezius, upper trapezius and shoulder external rotators will be strengthened with theraband.
