ABSTRACT

Objective: To evaluate the analgesic efficacy of two physical environments of nearly new use in rehabilitation service on patients with osteoarthritis of the knee. Transcutaneous electro-stimulation (tens) and low-level laser. Design: Comparative, prospective, observational, randomized, crossed and double-blind study. Subjects: Ambulatory patients with osteoarthritis of the knees with radiologic state stage 2 of Kellgren and upper pain of 5 in a visual analog scale (VAS) from 0-10. Measurements: Daily pain quantification on VAS and daily register of analgesic drug use. Method: Eighty-one patients formed part of one of four groups named A, B, C and, D receiving respectively laser, lase-like placebo, tens and tens-like placebo for 15 sessions; subsequently, groups A and B formed a new group named I, patients received 15 sessions of tens, and groups C and D formed a new group named II who received 15 sessions of low-level laser. Results: Tens showed to have analgesic effect as in group C as in group I (p ‹ 0.05), and diminished analgesic drug use; laser therapy did not show to be better than placebo as appreciated in groups A and B; in group II, the patients needed to increment analgesic drug use. In conclusion, at the rehabilitation service low-level laser do not have any indication in osteoarthritis of knee treatment, different from with tens, that has an important usefullnes to modify knee pain.
