Effect of Transcranial Direct Current Stimulation on Peripheral Neuropathy

This study will be performed in patients with peripheral neuropathy who are walking independently, but have complains of balance problems such as recent falls or difficulty walking and show reduced vibratory and proprioceptive sensation during routine neurologic examination. These patients will be tested for proprioceptive and vibratory threshold at the toes and ankles before, during and after receiving anodal direct transcranial cortical stimulation (dTCS) over sensory and motor cortices. Subjects will be asked to participate in 2 sessions.
