In order to establish the low energy laser (LEL) effects on nervous tissue regeneration in clinical practice, we evaluated in double blind, placebo controlled study, the efficacy of LEL in the functional recovery of 46 patients with distal forearm post- traumatic nerve lesion, after surgical suture. The patients were divided into two groups: A-26 patients were treated with LEL; B- 20 patients, as control, 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 about 3 mW. Before, during and after the treatment, electromyography (EMG) and electroneurography (ENG) were done in order to measure objectively the efficacy of the treatment. We obtained good results after 4 - 5 months at 80.7% patients from group A and about the same results at 70% patients from group B, but after at least 8 months. The good results were noticed concerning the improvement of EMG and ENG registrations and on the involution of pain, inflammations, movements and force of the fingers. Finally we can say that the favorable results were obtained in at least half the time with LEL treatment faster than with classical therapy. |
