“…Only one article reported the criterion validity of ActiGraph type for both step counting and distance. Experiments were performed in older adults (n = 4) [ 1 , 10 , 16 , 50 ] and in adults (n = 16) [ 11 , 22 , 24 , 25 , 27 , 51 – 61 ]. In one study, assessment was performed in adults and older adults [ 26 ].…”

Background Wearable activity monitors such as ActiGraph monitoring devices are widely used, especially in research settings. Various research studies have assessed the criterion validity of ActiGraph devices for step counting and distance estimation in adults and older adults. Although several studies have used the ActiGraph devices as a reference system for activity monitoring, there is no summarized evidence of the psychometric properties. The main objective of this systematic review was to summarize evidence related to the criterion validity of ActiGraph monitoring devices for step counting and distance estimation in adults and/or older adults. Methods Literature searches were conducted in six databases (Medline (OVID), Embase, IEEExplore, CINAHL, Engineering Village and Web of Science). Two reviewers independently conducted selection, a quality analysis of articles (using COSMIN and MacDermid’s grids) and data extraction. Results This review included 21 studies involving 637 participants (age 30.3 ± 7.5 years (for adults) and 82.7 ± 3.3 years (for older adults)). Five ActiGraph devices (7164, GT1M, wGTX +, GT3X +/wGT3X + and wGT3X − BT) were used to collect data at the hip, wrist and ankle to assess various walking and running speeds (ranging from 0.2 m/s to 4.44 m/s) over durations of 2 min to 3 days (13 h 30 mins per day) for step counting and distance estimation. The ActiGraph GT3X +/wGT3X + and wGT3X − BT had better criterion validity than the ActiGraph 7164, wGTX + and GT1M according to walking and running speeds for step counting. Validity of ActiGraph wGT3X + was good for distance estimation. Conclusion The ActiGraph wGT3X − BT and GT3X +/wGT3X + have good criterion validity for step counting, under certain conditions related to walking speeds, positioning and data processing.

“…For example, we could have placed the sensors on the ankle to enhance step sensitivity. A study by Bezuidenhout et al [ 39 ] on ActiGraph monitors has shown ankle placement to be more sensitive in measuring steps than hip worn placement monitors. However, we chose to place the monitors on the thigh as this is the placement suggested by the developers of both ActivPAL and SENS.…”

To evaluate interventions to promote physical activity, valid outcome measures are important. This study evaluated the validity and reliability of the ActivPAL3™ and the SENS motion® activity monitors with regard to the number of steps taken, walking, and sedentary behavior in hospitalized patients ( n = 36 ) (older medical patients (+65 years) ( n = 12 ), older patients (+65) with acute hip fracture ( n = 12 ), and patients (+18) who underwent acute high-risk abdominal surgery ( n = 12 )). Both monitors showed good (≥60%) percentage agreement with direct observation for standing and no. of steps (all gait speeds) and high agreement (≥80%) for lying. For walking, ActivPAL3™ showed moderate percentage agreement, whereas SENS motion® reached high percentage agreement. The relative reliability was moderate for sedentary behavior for both monitors. The ActivPAL3™ showed poor (walking) to moderate (steps) reliability for walking and steps, whereas SENS motion® showed moderate reliability for both activities. For slow walkers, the relative reliability was moderate for SENS motion® and poor for ActivPAL3™. This trial is registered with the ClinicalTrials.gov identifier NCT04120740.

“…However, in the HoPE-MOR study, the ActiGraph was worn on the ankle, shown to be a more sensitive sensor placement than hip placement. 40 Thus, some of the difference in the number of steps detected in the two samples may be indicative of the sensor placements.…”

Objective: Low in-hospital mobility is widely acknowledged as a major risk factor in acquiring hospital-associated disabilities. Various predictors of in-hospital mobility limitations have been proposed across studies, however, it is unknown whether similar risk factors are associated with in-hospital mobility across countries, given different mobility measurement methods, variations in measurement of predictors, and differences in populations studied. The study was a secondary analysis of data investigated the relationship between in-hospital mobility and a set of similar risk factors in older adults who were independently mobile prior to hospitalization in acute care settings in Israel (N=206) and Denmark (N=113). In Israel, mobility was measured via ActiGraph GT9X and in Denmark by ActivPal3 up to seven hospital days. Results: Higher level of community mobility prior to hospitalization and higher mobility ability status on admission were common predictors of a higher number of in-hospital steps, whereas longer length of hospital stay was significantly correlated with a lower number in both samples. Risk of malnutrition on admission was correlated with a lower number of steps, but only in the Israeli sample. Despite different measurement methods, older adults’ low in-hospital mobility has similar risk factors in Israel and Denmark: pre-hospitalization mobility and admission mobility ability.
