Complex Walking With Active tDCS
Neurorehabilitation of Complex Walking and Active Transcranial Direct Current Stimulation (Active tDCS) Neurorehabilitation of Complex Walking: Neurorehabilitation is a behavioral therapeutic approach for enhancing the neural control of task performance by: Restoration of function, specificity of training, Sensory input to the nervous system, Intensity, Repetition and Progression of training. Neurorehabilitation of complex walking will focus on the use of walking tasks that require increased attention and executive functions. The following walking tasks will be used: over obstacles, navigating around obstacles, changing speeds, on soft surfaces (exercise mat), in dim lighting, while conversing with the therapist, up/down ramps and climbing/descending stairs. Acive Transcranial Direct Current Stimulation (Active tDCS): tDCS will be used to induce positive neuromodulation of frontal/executive circuits to make them more amenable to the "activity-dependent neuroplasticity" that is known to occur with behavioral neurorehabilitation. Specifically, tDCS may facilitate the efficacy of our walking neurorehabilitation intervention by strengthening the synaptic connections within the recruited circuits.
Complex Walking With Sham tDCS
Neurorehabilitation of Complex Walking and Sham Transcranial Direct Current Stimulation (Sham tDCS) Neurorehabilitation of Complex Walking: Neurorehabilitation is a behavioral therapeutic approach for enhancing the neural control of task performance by: Restoration of function, specificity of training, Sensory input to the nervous system, Intensity, Repetition and Progression of training. Neurorehabilitation of complex walking will focus on the use of walking tasks that require increased attention and executive functions. The following walking tasks will be used: over obstacles, navigating around obstacles, changing speeds, on soft surfaces (exercise mat), in dim lighting, while conversing with the therapist, up/down ramps and climbing/descending stairs. Sham Transcranial Direct Current Stimulation (Sham tDCS): Sham tDCS is a placebo to Active tDCS.

Neurorehabilitation of standard walking will focus on the use of typical steady state walking. Sham Transcranial Direct Current Stimulation (Sham tDCS): Sham tDCS is a placebo to Active tDCS.

EXAMINER is an acronym for "Executive Abilities:Measures and Instruments for Neurobehavioral Evaluation and Research. EXAMINER is a battery of assessments that tests 7 domains of executive function separately and as a composite score. The composite score is based on Item Response Theory (logistic modeling) and ranges from a minimum value of -4 to a maximum value of 4. Higher scores indicate better performance.
