Brief summary

There are several therapeutic effects of the ultrasound (US) or low level laser therapy (LLLT), including pain relief, increase of microcirculation, modulation of inflammatory response and accelerated tissue repair. The investigators hypothesis was that a combination of US, LLLT and therapeutic exercise may maximize clinical outcome.

Detailed description

Patients with pain, especially chronic pain, avoid movements. This is turn results in a gradual impairment of their physical condition, reducing, for example, strength, flexibility, physical functionality and occupational activity. To performed physical treatments, a prototype device was development. The device includes four diode laser beams (808 nm) around of the one ultrasound transducer.

Interventions

DEVICEUltrasound plus Laser and therapeutic exercise

Ultrasound with frequency 1 Mhz and infrared laser with output power at 100 mW. The resistance training was performed.The treatments are done once a week, for 3 months.

DEVICEUltrasound plus Laser

Ultrasound with frequency 1 Mhz and infrared laser with output power at 100 mW. The treatments are done once a week, for 3 months.

DEVICEUtrasound plus Laser Placebo

The device with Ultrasound and infrared laser without emitting electromagnetic or mechanical waves was applied (null dose).
