The overarching goal of this Discovery Proposal is to evaluate neural activity during unipedal and bipedal movement in a cohort of healthy individuals (Aim 1).
The rigor and reproducibility will be evaluated by comparing the results of 1) active movement -Bipedal with 2) active movement -unipedal 4 and 3) imagined movement.
Dependent measures include: 1) head motion during the fMRI task, 2) BOLD signal in the ipsilateral and contralateral motor cortex during the fMRI task, 3) force applied during the fMRI task, and 4) participant feedback using a modified version of the Presence Questionnaire (a standard tool to assess ecological validity of virtual environments.
Each Aim has a development and evaluation aspect. Through this 1 year proposal the investigators will determine if the bipedal fMRI protocol (active movement) is able to engage neural networks more robustly (e.g. greater effect size) than bipedal imagery alone in Healthy Volunteers.
Specific Aim #1: Healthy volunteers: The investigators will test the hypothesis that with active bipedal movement there will be 1) no difference in head movement, but 2) greater motor cortex BOLD signal, 3) smoother force exchange between the feet, 4) higher participant satisfaction than unipedal movement or motor imagery alone. This sample size was selected based on a prior publication of imagined movement. The outcome of this aim may result in the first publication in the field to evaluate bipedal movement in an MR-environment.

Experimental: GAITRite assessment
Subjects will undergo the GAITRite assessment of functional walking and then complete the Functional MRI Bipedal paradigm followed by questionnaires and assessments regarding the virtual environment.
Device: GAITRite assessment
The fMRI Bipedal Paradigm will allow investigators to study the effects treadmill-assisted gait training have on cortical control of bipedal movement in chronic stroke patients.
Other Name: fMRI Bipedal Paradigm
- fMRI protocols will measure neural function activity during active bipedal movement in healthy volunteers [ Time Frame: Duration of the study, approximately 1 year ]Determine if the bipedal fMRI protocol (active movement) is able to engage neural networks more robustly (e.g. greater effect size) than bipedal imagery alone in healthy volunteers.
