Primary Outcome Measures:
  • integrated measure of thinking while walking [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    The outcome measure is a cognitive task such as working memory, visuo-spatial orientation, and set shifting measures of cognitive function performed while walking over an oveal track.

Secondary Outcome Measures:
  • gait [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    energy cost of walking, gait smoothness, gait speed and spatial and temporal gait characteristics under usual and challenging gait conditions, gait abnormalities, and walking endurance

Estimated Enrollment: 24
Study Start Date: January 2011
Estimated Study Completion Date: August 2013
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: motor skill arm Behavioral: motor skill gait exercise
The motor skill gait exercise is a task-oriented motor sequence learning approach to exercise to improve walking. The approach involves goal-directed stepping and walking patterns to facilitate use of the appropriate muscles at the appropriate timing relative to body position during gait through the task performance. Treadmill-assisted walking in brief intervals of small increased speed walking interspersed with usual walking speed are performed to induce the automatic rhythm and timing of gait. The exercise sessions are about 60 minutes, 2-3 times a week for 12 weeks or a total of 30-36 sessions.
Other Names:
  • task-oriented motor sequence gait exercise
  • motor learning gait exercise
  • timing and coordination therapeutic gait activity
Active Comparator: aerobic arm Behavioral: aerobic gait intervention
The aerobic gait intervention approach involves treadmill and overground walking with the gradual increases in the distance walked and speed of walking. The exercise approach provides walking practice, including on the treadmill to facilitate the timing of stepping during gait, while also facilitating a fitness or conditioning response, and endurance for walking activities. The exercise sessions are about 60 minutes, 2-3 times weekly for 12 weeks, or about 30-36 sessions.
Other Names:
  • walking endurance exercise
  • aerobic walking training
  • impairment-oriented gait exercise
