The low energy laser (LEL) biostimulatory effects on nervous tissue regeneration are well known. Thirty two patients with medial and/or radial nerve traumatic forearm lesion after surgical suture were divided into two groups: A-18 patients were treated with LEL; B-14 patients, witness, were treated with placebo lasers and classical medical and physical therapy. Lasers used were: HeNe, 632.5 nm wavelength, 2 mW power, and GaAlAs diode laser, 880 nm wavelength, pulsed emission with an output power 2 mW. Before, during, and after treatment EMG was done in order to measure objectively the efficiency of the treatment. We obtained good results after 4 - 5 months at 14 patients (77.7%) from group A and about the same results at 10 patients (71.3%) from group B, but after at least 8 months the good results were noticed concerning the improvements of EMG registration and on movements and force of the fingers. Finally we can say that the favorable results were obtained in at least twice shorter time with LEL treatment than with classical therapy.
