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 .
Accuracy of step count measured by physical activity monitors: The effect of gait speed and anatomical placement site.
INTRODUCTION Consumer-based physical activity monitors ( PAMs ) are becoming increasingly popular , with multiple global organisations recommending physical activity levels that equate to 10,000 steps per day for optimal health . We therefore aim ed to compare the step count of five PAMs to a visual step count to identify the most accurate monitors at varying gait speeds , along with the optimal anatomical placement site . METHODS Participants completed 3min on a treadmill for five speeds ( 5.0 km/h , 6.5 km/h , 8.0 km/h , 10 km/h , 12 km/h ) . An Actigraph wGT3XBT-BT was placed on the waist and wrist , a FitBit One on the waist , and a Fitbit Flex , Fitbit Charge HR and Jawbone UP24 on both wrists . A video of participant 's lower limbs was recorded for visual count . Analyses of variance ( ANOVAs ) were conducted to examine the effects of gait speed and device placement site on step count accuracy . RESULTS Thirty-one participants ( mean age 24.3±5.2yrs ) took part . Step count error ranged from 41.3±13.8 % for the wrist-worn Actigraph to only 0.04±4.3 % and -0.3±4.0 % for the waist-worn Fitbit One and Actigraph , respectively . Across all gait speeds , waist-worn devices achieved better accuracy than those on the wrist ( p<0.001 ) . The Jawbone was the most accurate wrist-worn consumer-based device at slower speeds ( p=0.026 ) , with the Fitbit Flex , and Fitbit Charge HR increasing in accuracy to match the Jawbone at higher speeds . CONCLUSION The accuracy and reliability of consumer-based PAMs and the Actigraph is affected by anatomical placement site and walking speed . The Fitbit One and Actigraph on the waist were the strongest performers across all speeds
