Brief Summary:
The investigators propose a single-blind randomized clinical trial to determine if seniors show improved mobility (walking speed) and cognition following motor imagery (imagined walking) training. They hypothesize that imagined walking can be used as a rehabilitative tool for improving walking speed and cognition in the elderly, because it engages and strengthens similar neural systems as actual walking and cognition.

Detailed Description:
The proposed research aims to establish the efficacy of an imagined gait protocol for improving gait and cognition in the elderly. This imagined gait protocol involves imagined gait in single (imagined walking; iW) and dual-task (imagined walking while talking; iWWT) situations. A single-blind randomized clinical trial of 58 cognitively-healthy elderly with pre-post measures of gait, cognition, and functional Magnetic Resonance Imaging (fMRI) during imagined gait is proposed. The overall hypothesis is that imagined gait can be used as a rehabilitative tool for improving gait and cognition in the elderly because it engages and strengthens similar neural systems as actual gait and cognition. The first aim of this study is to establish the efficacy of our imagined gait protocol to improve gait and cognition in the elderly. We predict that our imagined gait intervention will improve gait velocity during actual walking and walking-while-talking conditions to a greater extent than the active control (visual imagery) intervention. We also predict that our imagined gait intervention will cognitive performance during dual-task walking conditions. The second aim of this study is to determine neuroplasticity changes in response to our imagined gait protocol. We predict that the neural systems engaged during imagined gait will change following our imagined gait intervention.

Arm Intervention/treatment
Experimental: Imagined Gait Intervention
During the phone-based imagined gait intervention, participants will be called by the experimenter three times a week and be asked to imagine walking, imagine talking and imagine walking-while-talking. They will also be asked to rate their visual and kinesthetic qualities of their images on a 1-5 scale following each trial.
Behavioral: Imagined Gait Intervention
Phone-based imagined gait intervention: participants will be called by the experimenter three times a week and be asked to imagine walking, imagine talking and imagine walking-while-talking. They will also be asked to rate their visual and kinesthetic qualities of their images on a 1-5 scale following each trial.

Active Comparator: Visual Imagery Intervention
During the phone-based visual imagery intervention, participants will be called three times a week by the experimenter and be asked to imagine concrete objects (e.g. octopus, teapot, and shovel). They will also be asked to rate their visual qualities of their images on a 1-5 scale following each trial.
