Physical activity levels measured by remote monitoring are consistently low in people with MS , stroke and dementia , and patterns of physical activity are altered in PD .
In MS , decreased ambulatory activity assessed via remote monitoring is associated with greater disability and lower quality of life .
In stroke , remote measures of upper limb function and ambulation are associated with functional recovery following rehabilitation and goal -directed interventions .
In PD , remote monitoring may help to predict falls .
In dementia , remote physical activity measures correlate with disease severity and can detect w and ering .
Conclusions These studies show that remote physical activity monitoring is feasible in neurological diseases , including in people with moderate to severe neurological disability .
Remote monitoring can be a psychometrically sound and responsive way to assess physical activity in neurological disease .
Objective To perform a systematic review of studies using remote physical activity monitoring in neurological diseases , highlighting advances and determining gaps .
Physical activity and risk of cognitive impairment among oldest-old women.
OBJECTIVES Physical activity may reduce the risk of cognitive decline in the elderly , but its effects among the oldest-old ( i.e. , those aged 85 years and older ) are not well known . Our study assessed the association between very late-life physical activity and 5-year risk of  mild cognitive impairment ( MCI ) or dementia and neuropsychological test performance among oldest-old women . METHODS This prospect i ve study was conducted at three sites . Participants included 1,249 women ( mean [ st and ard deviation ] age : 83.3 [ 2.8 ] years ) .  Baseline physical activity  was measured by self-reported blocks walked per week and analyzed according to tertile . Five years later , surviving participants who were 85 years and older ( oldest-old ) completed neuropsychological testing and underwent adjudication of clinical cognitive status ( normal , MCI , or dementia ) . All analyses were adjusted for baseline age , education , cognition , depression , body mass index , hypertension , smoking , and coronary artery disease . RESULTS Compared with women in the lowest tertile , women in the highest tertile were less likely to develop dementia ( 13.0 % versus 23.2 % ; multivariate adjusted odds ratio : 0.54 [ 95 % confidence interval : 0.36 - 0.82 ] ) . However , risk of MCI was not associated with physical activity . Physical activity was also associated with higher performance 5 years later on tests of global cognition , category fluency , and executive function but not phonemic fluency , memory , or attention . CONCLUSIONS Higher level of very late-life physical activity was associated with a lower risk of subsequent dementia  in oldest-old women . These findings support future studies for late-life physical activity interventions for the prevention of dementia among oldest-old women
