Abstract:

Diabetic peripheral neuropathy (DPN), presents in up to half of the people with diabetes, leading to sensory motor and autonomic impairment, and possibly increasing the risk of falling. Transcranial direct current stimulation (tDCS) modulates cortical excitability of the stimulated somatosensory cortex which in turn modifies brain functions resulting in neuroplastic changes.To investigate effect of (tDCS) on sensory integration and risk of falling in patients with diabetic polyneuropathy.Thirty patients diagnosed with diabetic polyneuropathy were enrolled in this study. They were divided randomly into two equal groups. Control group (GI) treated with designed physiotherapy program and study group (GII) treated with the same physiotherapy program plus tDCS over the somatosensory area of the left side. Treatment was conducted Three times per week for two months. Biodex balance system was used to assess sensory integration (sway index) in four sensory conditions and risk of falling pre and post treatment for both groups.Significant reductions of sway indices in all four sensory conditions and risk of fall index were observed in both groups post treatment with more reduction in favor to study group (P<0.05).Adding transcranial direct current stimulation to designed physiotherapy program result in more improvement of sensory integration and reduction of risk of falling than physical therapy alone in patients with diabetic polyneuropathy.
