Background. Impaired gait in older people is associated with disabilities in daily life and increased fall risk. This study aimed to examine distributions, stability and clinical associations of acceleration derived gait measures with an unfixed body-worn device suitable for unsupervised environments. Methods. Fourteen participants (mean age: 83.0±7.0y) wore the accelerometer device in their home environment, from which gait measures were calculated (number of steps, number of walks, cadence, gait vigour and step time variability) over three days. Clinical tests of physical function (muscle strength, postural sway, 5STS, TUG), cognitive function (Stroop test), and psychological aspects (Icon-FES) were assessed. Relations between gait measures and clinical tests were calculated using Pearson’s correlation. Differences between clinical performance groups on gait measures were obtained using Wilcoxon signed-rank and Mann-Whitney U test. Results. Distributions of number of steps, cadence and gait vigour were similar over participants. The range of performed cadence was larger for short walks than for long walks. Step time variability was normally distributed in frailer participants and positively skewed in fitter participants. Ranges of step time variability between short and long walks were different in fitter participants (p=0.046), but similar in frailer participants (p=0.398). Conclusion. Three-day derived gait measures were similarly distributed across older adults, stable, and associated with performance on several clinical tests. The current study supports the use of the SMM for continuous and in-home monitoring to provide insight into daily activity routines and quality of gait.
