The effect of soft-laser therapy on rheumatoid arthritis was evaluated in 17 patients with symmetrical involvement of the metacarpophalangeal joint of the index. Nine treatments with a He-Ne laser, 6 J/cm2, were given on the one hand with a sham irradiation of the other. The study was double-blind.
