Arm Intervention/treatment
Experimental: Timing and Coordination Behavioral: Timing and Coordination
This intervention is based on progressively difficult stepping and walking patterns that promote the timing and coordination of stepping within the gait cycle. Small-group 60-minute classes twice weekly for 12 weeks.

Experimental: Aerobic Walking Behavioral: Aerobic Walking
Outdoor walking with progressive increases in exercise intensity. Small-group 60-minute classes twice weekly for 12 weeks.

Active Comparator: Stretching and Relaxation Behavioral: Stretching and Relaxation
Full-body stretching, range-of-motion exercises, and relaxation techniques. No specific gait training. Small-group 60-minute classes twice weekly for 12 weeks.




Primary Outcome Measures :
  1. energy cost of walking [ Time Frame: 12 weeks ]
    assessed by oxygen consumption during treadmill and overground walking

  2. fatigue and fatigability [ Time Frame: 12 weeks ]
    assessed by questionnaire, rated perceived exertion during walking, and decrements in walking performance over time.

  3. daily activity [ Time Frame: 12 weeks ]
    assessed by accelerometry and the Physical Activity Scale for the Elderly

  4. life-space mobility [ Time Frame: 12 weeks ]
    assessed by life-space mobility questionnaire

  5. endurance [ Time Frame: 12 weeks ]
    assessed by the long-distance corridor walk

  6. physical function [ Time Frame: 12 weeks ]
    assessed by standing balance, gait speed, and chair stands


Secondary Outcome Measures :
  1. energy cost of walking [ Time Frame: 24 weeks ]
    assessed by oxygen consumption during treadmill and overground walking

  2. fatigue and fatigability [ Time Frame: 24 weeks ]
    assessed by questionnaire, rated perceived exertion during walking, and decrements in walking performance over time

  3. daily activity [ Time Frame: 24 weeks ]
    assessed by accelerometry and the Physical Activity Scale for the Elderly

  4. life-space mobility [ Time Frame: 24 weeks ]
    assessed by the life-space mobility questionnaire

  5. endurance [ Time Frame: 24 weeks ]
    assessed by the long-distance corridor walk

  6. physical function [ Time Frame: 24 weeks ]
    assessed by standing balance, gait speed, and chair stands
