From: Recommended motor assessments based on psychometric properties in individuals with dementia: a systematic review

  Alzheimer’s disease Various types/not reported
BBS ICC = 0.95 MDC95% = 38.6% [14] ICC = 0.99 MDC95% = 10.2% [43]
TUG (between-day reliability) ICC = 0.72–0.76 (MDC95% = 20.3–24.9%) [14, 51] ICC = 0.87–0.99 (MDC95% = 15.8–39.6%) [17, 43, 102]
