Conclusion : Based on available evidence , older adults with hip fracture engage in prolonged sedentary behavior and have low levels of physical activity during rehabilitation and recovery
Objective : To synthesize evidence on older adults ’  sedentary behavior and physical activity during rehabilitation and recovery for hip fracture ( 1 ) across the care continuum and ( 2 ) from clinical interventions .
Quantification of Outdoor Mobility by Use of Accelerometer-Measured Physical Behaviour
Hip fractures in older persons are associated with both low levels of daily physical activity and loss of outdoor mobility . The aim was to investigate if accelerometer-based measures of physical behaviour can be used to determine if people undertake outdoor walking and to provide reference values for physical behaviour outcomes related to outdoor mobility . Older persons ( n = 245 ) , ≥70 years , one year after hip fracture , participated .  Six objective measures of physical behaviour collected by an activity monitor were compared with self-reported outdoor mobility assessed with the Nottingham Extended ADL scale . All measures of time and length in upright periods were significantly lower in participants who reported not walking outdoors ( p < 0.001 ) . A set of cut-off points for the different physical behaviour variables was generated . Maximum length of upright events discriminated best between groups , with 31 minutes as a threshold to determine if a person is more likely to report that they walk outdoors ( sensitivity : 0.805 , specificity : 0.704 , and AUC : 0.871 ) or 41 minutes or more to determine if a person is more likely to report outdoor walking on their own ( AUC : 0.891 ) . Physical behaviour  variables from activity monitoring can provide information about patterns of physical behaviour related to outdoor activity performance
