Chronic Shoulder Pain Treatment: High Intensity Laser or Ultrasound

Chronic shoulder pain, which negatively affects the quality of life due to pain and loss of functions, is the third most common painful condition of the musculoskeletal system\[1\] The aim of the study was to determine more effective conventional physical treatment method (HILT or US) for pain and daily activities of patients with chronic shoulder pain which was difficult to treat, and had unfavorable effects on patient life quality. This prospective, randomized, controlled, single blind study was conducted at the Physical Treatment and Rehabilitation Training and Research Hospital and ethics board approval was obtained.A total of 210 patients, who presented to the hospital with chronic shoulder pain, were evaluated for inclusion in the study. Patients to be included in the study were divided into two groups by the investigating physician, using simple randomization, and their treatment was organized. Forms detailing the patients' (demographics, VAS scores and SPADI) were completed by another investigating physician who was blind to the type of treatment the patients would receive. The same investigating physician completed Post-treatment 1st day (Post-T1st day) and Post-T findings for the 30th day (Post-T 30th day) forms and recorded the data. Patients who were randomly divided into two groups received treatment for two weeks (14 days) are shown below: * Group 1: Hotpack (HP)+ Balneotherapy+ Exercise + HILT * Group 2: Hotpack (HP)+ Balneotherapy+ Exercise + US Patients in both groups received HP to the affected shoulder region for 20 minutes and balneotherapy, in mineral water pool at 38-400C for 20 minutes, for seven consecutive days. ROM exercises and Codman exercises, in a level not to increase the severity of the pain of the patient, were given and stretching and strengthening exercises were taught to the patients.The patients performed these exercises daily in two sets with five repeats in each set. HILT was performed using a BTL-6000 High Intensity Laser, 12 W(watt), 1064 nm device was a hot laser with Nd: YAG LASER source. BTL 4710 US device was applied at 3 MHz frequency, and 1.5watt/cm2 intensity over 25 cm2 surface area. Headpiece area of the device was 5 cm2, and the application was performed as the head of device was positioned at 90º (perpendicular) at full contact for 5 minutes by using gel, and performing continuous circular motions. Patients were evaluated using VAS and SPADI in pre-treatment (Pre-T), Post-T1st day and Post-T 30th day.
