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.
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.
