History of Changes
  Purpose

The goal of this research is to determine if real time visual feedback of body movements improves balance control more than walking on a treadmill alone. Individuals participating in this research study will be tested using a battery of clinical strength and balance assessments twice before a 4 week training period and once after the training period. The 4 week training period will consist of 12 sessions walking on a treadmill. The experimental group will see real time visual feedback regarding their body movements, and the control group will not receive this visual feedback. Following the 4 week training each participant will again be tested using the battery of clinical strength and balance assessments.

Primary Outcome Measures:
  • Change from Baseline in BESTest Score, A clinical assessment of balance [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: Yes ]
  • Change from Baseline in Berg Balance Test Score [ Time Frame: Test will be given at 0, 4, and 8 weeks ] [ Designated as safety issue: Yes ]
  • Change from Baseline in Activity Specific Balance Confidence Score [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: No ]
    Questionnaire rating balance confidence

  • Change from Baseline in 6 Minute Walk Test [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: No ]
  • Change from Baseline in Comfortable Walking Speed [ Time Frame: Measured daily, up to 12 days ] [ Designated as safety issue: No ]
    This value is determined for each training session


Secondary Outcome Measures:
  • Change from Baseline in Muscle Strength [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: No ]
    Strength of major muscles in the legs and trunk will be measured

  • Change from Baseline in Overground Walking Speed [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: No ]
  • Change from Baseline in COM variability [ Time Frame: Tested daily, up to 12 days ] [ Designated as safety issue: No ]
    This measure is derived from recorded body position during each training repetition for each of up to 12 days of training.

  • Change from Baseline in Power spectral density [ Time Frame: Tested daily, up to 12 days ] [ Designated as safety issue: No ]
    This measure is derived from recorded body position during each training repetition for each of up to 12 days of training.

  • Change from Baseline in Single/Dual Tasking ability [ Time Frame: Tested at 0, 4, and 8 weeks ] [ Designated as safety issue: No ]

Estimated Enrollment: 76
Study Start Date: June 2011
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Walking & Visual Feedback
Individuals in this arm will walk on a treadmill while viewing real time visual feedback regarding their body motions and use the visual feedback to correct their body motions.
 Procedure: Treadmill Walking
Individuals will walk at a "comfortable speed" on a treadmill without holding on to the hand rails.
Other: Visual Feedback
Real time feedback regarding body motion while walking.
Active Comparator: Walking & No Visual Feedback
Individuals in this arm will walk on a treadmill without viewing real time visual feedback regarding their body motion.
 Procedure: Treadmill Walking
Individuals will walk at a "comfortable speed" on a treadmill without holding on to the hand rails.
