Enhanced Acute Muscle Activation in ALS Patients Following Liposomal Curcumin, Resveratrol, and Dutasteride Administration

<b>Introduction:</b> Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by loss of electrical activity and motor control at the muscular level. Therapeutic alternatives, such as the polyphenolic antioxidants curcumin and resveratrol in liposome form, or the drug dutasteride, could be effective for muscular activity. <b>Objective:</b> To measure the acute change in electrical muscle activation after administration of a combination of curcumin in liposomal form, resveratrol, and dutasteride in patients with ALS. <b>Materials and methods:</b> Patients with bulbar and spinal ALS were selected and randomly distributed into an intervention group (IG), which received an oral combination of curcumin in liposomal form/resveratrol^® and dutasteride for 2 months, and a control group (CG), which received a placebo. Electrical activity to determine basal muscle activation and fasciculations was measured before and after the intervention using surface electromyography of the biceps brachii (BB), triceps brachii (TB), rectus femoris (RF), and tibialis anterior (TA). Within comparisons of pre and post-muscular variations in each group were conducted. <b>Results:</b> Electrical basal activity increased only for the IG in the right (<i>p</i> = 0.05; g = -0.45) and left (<i>p</i> = 0.004; g = -0.74) hemibody muscles and also presented less variation among them after treatment in the IG. For fasciculations, there was an increase in the total activation of the upper muscles in the IG (<i>p</i> = 0.017; g = -0.86) and for the lower muscles in the CG (<i>p</i> = 0.037; g = -0.68). The pattern of muscle activation remained constant in the IG but experienced variations in the CG.
