Effectiveness of High Intensity Laser Treatment In Partial Supraspinatus Tendon Tears

Summary

The primary goal of this clinical trial is to compare the effects of High Intensity Laser Therapy (HILT) on tears of tendons of shoulder girdle muscles with those of Ultrasound (US) therapy. It will also learn about the effects of HILT on pain and range of motion of injured shoulder. The main questions it aims to answer are:

Does HILT decrease the debilitating pain? Does HILT increase the range of motion of the sholuder joint? How long does the effect of HILT continue?

Researchers will compare the effects of HILT to a control group (ultrasound therapy group, an established method of treatment in shoulder girdle tendon tears) to see if HILT works better to treat shoulder girdle tendon tears.

Participants will:

receive HILT or US therapy 3 sessions per week for 3 weeks in addition to the therapeutic exercise program.

Visit the clinic at the beginning, at the 4th week and at the 12th week to determine the level of pain and disability via application of surveys.

Tendon thickness of participants will also be measured at the beginning, at the 4th week and at the 12th week to see if the treatment works to heal the tear.

Conditions

• Shoulder Pain
• Supraspinatus Tear

Interventions

DEVICE

High intensity laser therapy

HILT was performed by a single physiotherapist experienced in using a laser device. During HILT application, the patients were seated comfortably on chairs and their shoulders were in neutral position. The wavelength of the laser light used was 1064 nanometers. In the HILT group, the device was used on the rotator cuff muscles in two stages: phase I and phase II. Pulse method was used in phase I for analgesic effect. A standard frequency of 25 Hz is applied. During the first four therapy sessions, it was aimed to provide an analgesic effect by using 8 W power and 12 J/cm dose. The rays were applied to the rotator cuff muscles area in a circle from outside to inside for 2.5 minutes, for a total energy of 300 J, on an area of 25 cm2. For the biostimulation effect, the continuous wave method was used in phase II. n the next five sessions, biostimulation effect was applied using 7W power. A dose of 100 J/cm was applied longitudinally to the rotator cuff muscles.

DEVICE

Ultrasound therapy

US therapy was performed by a single physiotherapist experienced in using US device. Calibration and control of the device are performed regularly. During US therapy, the patients were seated comfortably on chairs and their shoulders were in neutral position. The standard US dose was 1.2 W/cm2. The duration of ultrasound was 8 minutes. Using slow circular movements, the physiotherapist applied the transducer head of US device over the shoulder joint on an area of 25 cm2. US device was used in pulsed mode at a frequency of 1 MHz. The therapeutic ultrasound pulse cycle was 50%.

OTHER

Therapeutic Exercise

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. They performed these exercises daily in two sets with five repeats in each set underCalibration and control of the device are performed regularly.
