Ultrasound; Chattanooga® (US) 2776 model device, 3 MHz, treatment dose average 1.5 w/cm², 5 min ultrasound was applied to the anterior and posterior of the glenohumeral joint. Transcutaneous Electrical Nerve Stimulation (TENS); With Chattanooga®(US) 2770 model device, conventional TENS application with a frequency between 60 and 120 Hz and a transition time of 50-100 μsec was applied to the shoulder joint by interposing the painful area of the patient for 20 minutes. Infrared; Infrared rays were positioned perpendicularly to the pathological shoulder region of the patients with Orthocare®(Turkey) device and applied from a distance of 45-70 cm for 20 minutes.

Shoulder joint active and passive flexion, extension, abduction, internal and external rotation range of motion was evaluated before and after treatment with universal goniometer.

Shoulder pain assessment of the patients before and after treatment was performed with VAS and Short Form Mc-Gill Pain Questionnaire (SF-MPQ). The SF-MPQ provides information about the sensory, perceptual and intensity dimensions of pain by describing the pain. Pain is characterised by a total of 15 descriptive adjectives, 11 sensory and 4 affective. The total pain intensity of the patient was evaluated with a 6-point Likert-type scale as 0=no pain, 1=mild, 2=moderate, 3=severe, 4=bitter, 5=unbearable

Functional evaluation of the shoulder joint was performed before and after treatment using the University of California-Los Angeles (UCLA) Shoulder Scale, the Shoulder Pain and Disability Index (SPADI), and the Constant-Murley Shoulder Score (CMS). SPADI consists of two subscales assessing pain and disability, each scored from 0 to 100, with higher scores indicating greater pain and functional limitation. CMS evaluates shoulder pain, activities of daily living, range of motion, and muscle strength, yielding a total score of 100 points; higher scores reflect better shoulder function and are categorized as excellent, good, fair, or poor. The UCLA Shoulder Scale has a total score of 35 points, including pain (10 points), function (10 points), range of motion (10 points), and patient satisfaction (5 points), with higher scores indicating better outcomes.

Pittsburg Sleep Quality Index (PSQI) was applied. The PSQI consists of 7 parameters that assess sleep quality and sleep disturbance over a one-month period. The response of each parameter is evaluated with a score between 0-3 according to the frequency of the symptom. A total score above 5 indicates clinically poor sleep quality.
