Detectable Changes in Physical Performance Measures in Elderly African Americans

Abstract

The SEMs were similar to previously reported values and can be used when working with African American and white older adults. Estimates of MDC were calculated to assist in clinical interpretation.

Progressive resistance training for community-dwelling women aged 90 or older; a single-subject experimental design

“…Acceptable reliability and validity of the test have been demonstrated among community-dwelling elderly people [27]. Several studies [28] have recognized 1.0 m/s to be the cut-off value for adverse outcomes while an increase of 0.19 m/s has been documented [25] as a clinically relevant change for elderly people.…”

“…The improvements in mean shift ranged from 13% to 33%. At the final assessment, four participants (numbers 1, 2, 3 and 5) performed better than average for very old women [24] and four participants (numbers 1, 2, 4 and 6) obtained clinically relevant improvements in TUG (!4 s) [25] with a decrease in time to perform the test ranging from 4 to 12.5 s (Table 3). Furthermore, all except participant number 3 improved their walking speed significantly by 11% to 59% (mean shift) and half of the participants had a comfortable walking speed exceeding the cut-off for adverse outcome of 1 m/s at the final assessment.…”

“…Acceptable validity [19][20][21] and high intra-/inter-test and test-retest reliability [19,22,23] have been reported. For women aged 80-99 years, a performance above 12.7 s is regarded as worse than average [24] and a clinically relevant change for elderly people is reported to be 4 s [25].…”

Gait velocity, timed-up-and-go, and timed stair negotiation measurements using body-contact events are accurate and precise for use in patients following vascular surgery

“…Our largest MDC found in TUAG (1.912s) is small when compared to other literature reporting 3.5s in Parkinson's disease and in older adults [33,34]. Our small MDC is in keeping with the decision to report on repeated measurements of the same events; other studies used repeated patient measurements introducing realistic, but nonetheless greater variation.…”

The effect of hip joint exercise using an elastic band on dynamic balance, agility and flexibility in healthy subjects: a randomized controlled trial

“…Mangione et al [23] reported that TUG tests were decreased after performing progressive resistant exercises using an elastic band of older adults. Park et al [24] reported that strengthening exercise programs in the rural elderly population resulted in a decrease in TUG scores (from 9.8 to 9.0 sec).…”
