Clinical study of the effect of laser therapy in rheumatic degenerative diseases.

The effect of a 940-980 nm length wave laser radiation in rheumatic degenerative diseases was studied in 136 patients unresponsive to or with contraindications for antiinflammatory non-steroid therapy. The evolution was clinically estimated using four parameters; pain, muscular contracture, local edema and the impairment of the articular mobility. All patients presented a beneficial evolution appearing gradually during the treatment. The osteoarthritis of the knee, ankle and shoulder evolved worse than the painful back. The painful back presented an improved evolution when it was located at the thoracal level. No adverse reaction was observed during this study.
