No impact of patient and intervention characteristics on the effect estimates were found .
Short conclusion Low quality of evidence was found for a moderate effect of physical activity monitor-based interventions on physical activity compared with control interventions .
Background The body of evidence related to the effect of physical activity monitor-based interventions has grown over the recent years .
However , the effect of physical activity monitor-based interventions in older adults remains unclear and should be systematic ally review ed .
Objective The objective of this systematic review was to estimate the effect of physical activity monitor-based interventions on physical activity behavior  in participants aged 65 and above .
Subsequently we explored the effect on body mass index , physical capacity , and health-related quality of life and finally the impact of patient- and intervention characteristics .
Promoting Activity in Geriatric Rehabilitation: A Randomized Controlled Trial of Accelerometry
Background Low activity levels in inpatient rehabilitation are associated with adverse outcomes . The study aim ed to test whether activity levels can be increased by the provision of monitored activity data to patients and clinicians in the context of explicit goal setting . Methods A r and omized controlled trial in three sites in Australia included 255 in patients aged 60 and older who had a rehabilitation goal to become ambulant . The primary outcome was patients ’ walking time measured by  accelerometers  during the rehabilitation admission .  Walking times from accelerometry were made available daily to treating therapists and intervention participants to motivate patients to improve incidental activity levels and reach set goals . For the control group , ‘ usual care ’ was followed , including the setting of mobility goals ; however , for this group , neither staff nor patients received data on walking times to aid the setting of daily walking time targets . Results The median daily walking time in the intervention group increased from 10.3 minutes at baseline to 32.1 minutes at day 28 , compared with an increase from 9.5 to 26.5 minutes per day in the control group . Subjects in the intervention group had significantly higher non-therapy walking time by about 7 minutes [ mean ( 95 % CI ) : 24.6 ( 21.7 , 27.4 ) ] compared to those in the control group [ mean(95 % CI ) : 17.3 ( 14.4 , 20.3 ) ] ( p = 0.001 ) . Conclusions Daily feedback to patients and therapists using an accelerometer increased walking times during rehabilitation admissions . The results of this study suggest objective monitoring of activity levels could provide clinicians with information on clinical ly important , mobility-related activities to assist goal setting .
