We conducted a pilot, randomized, controlled trial to mainly investigate the feasibility, safety, and short-term motor effects of brain stimulation with radio electric asymmetric conveyer (REAC) technology in patients with advanced Alzheimer’s disease (AD) who also experience some gait dysfunction. Neuropostural optimization (NPO) or sham protocol was administered to 31 nursing home patients (mean [SD] age 84.7 [7.0], 77.4% female, 6.5% moderate dementia, 51.6% moderately severe dementia, and 41.9% severe dementia). Motor, cognitive, functional, and behavioral measures were conducted at baseline (T1), immediately after treatment (T2), and 1-3 weeks after treatment (T3). There was transitory dysfunction in axial movements at T2 in the experimental group with no other differences between the experimental group and the control group in the planned analyses. However, after reanalysis of data based on outcome, improvement in capacity of walking was observed at T3 in the experimental group (p < 0.05). NPO administration was comfortable and safe. These results warrant further research with NPO and other REAC protocols to improve motor deterioration in AD.;
