Résumé
To evaluate the clinical efficacy of low level LASER therapy on quality of life and neurophysiological studies in patients with diabetic polyneuropathy. Two groups of patients complaining of diabetic polyneuropathy were randomly assigned to one of two groups: First group [The study group]: included patients who were treated with LASER. Second group [Placebo group]: included patients who received LASER without activation of the laser beam [placebo LASER]. Baseline assessment for each patient by questionnaire, examination, investigations, and electrophysiological studies was done in the first visit then after 8 weeks of LASER therapy. Low level LASER therapy for 8 weeks had significant effect in improving severity of pain, quality of life and nerve conduction velocities of posterior tibial and common peroneal nerves in patients who received LASER therapy compared to placebo group. We concluded that low level LASER therapy is a safe, feasible and applicable method of treating and prophylaxis from diabetic polyneuropathy
