Chronic Shoulder Pain Treatment: High Intensity Laser or Ultrasound

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. In HILT group, the investigators applied the device on the shoulder area in two phases: phase I - analgesia, and phase II - biostimulation.

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.
