研究概览
简要总结
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.
详细描述
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 transcranial direct current stimulation (tDCS) over sensory and motor cortices. Subjects will be asked to participate in 2 sessions. In one of the sessions, decided randomly, the stimulation will be applied on the right side and in the second session it will be on the left.
The tDCS portion of the experiment will begins with direct current (maximum of 2 mA) stimulation delivered through surface electrodes (TransQE from IOMED®, surface area: 25 cm2) using a Phoresor® II Auto (Model No. PM850, IOMED®, Salt Lake City, Utah 84120, USA). One electrode will be positioned above the left or right primary motor cortex, the other electrode over the forehead.

结局指标
主要结局
Change in Vibratory Threshold as Measured by Rydel Seiffer Graduated Tuning Fork at the Toes
时间窗: At 10 and 20 minutes
Vibration is measured by reading in Rydel Seiffer tuning fork that ranges between 0-8 and is a standard tool fro measuring vibration sensation at the toes. A reading of 0 means absent vibration. A reading of more than 4 at the toes are considered normal. Change between assessment at 20 minutes and 10 minutes at the toes will be assessed. A recording of less than 4 indicates an abnormal results and a lower number means worse neuropathy. For example, reading of 0 means absent vibration feeling which indicates worse neuropathy than a reading of 2.
Change in Minimum Detectable Angle (Degree) of Dorsiflexion of the Toe
