Dynamic Gait Index

Overview and Statistics

 

Purpose: 8-item test that assesses dynamic balance and gait ability

Diagnoses Assessed:

  • Multiple Sclerosis
  • Parkinson's Disease
  • Strokes
  • Vistibular disorders
  • Geriatrics

Disease-Specific Statistical Breakdown:

Multiple Sclerosis:

  • SEM:
    • For intra-rater reliability=1.51 points
    • For inter-rater reliability=2.00 points
  • MDC=4.19-5.54 points
  • Cut-off score: <12=fall risk
  • Test-retest reliability=.85
  • Intra-rater reliability=.76-.98
  • Inter-rater reliability=.98

Parkinson's Disease:

  • MDC=2.9 points or 13.3% change
  • Cut-off score: <19=higher risk of falls
  • Test-retest reliability=.99

Strokes:

  • SEM:
    • For intra-rater reliability=.97
    • For inter-rater reliability=.94
  • MDC=2.6 points
  • Test-retest reliability=.94
  • Inter-rater reliability=.96

Vestibular Disorders:

  • SEM=2.8 points
  • MDC=3.2 points
  • Cut-off score: <12=fall risk
  • Test-retest reliability=.86
  • Inter-rater reliability=.64

Geriatrics:

  • SEM=1.04 points
  • MDC=2.9 points
  • MCID:
    • 1.80 for subjects with DGI of 22-24
    • 0.60 for subjects with DGI of 21 or less
  • Cut-off score: 19 or less=fall risk
  • Intra-rater reliability=.90
  • Inter-rater reliability=.92
