Active computer gaming (ACG) is a method of facilitating physical
activity in older people to improve health outcomes.
The purpose of this
study was to update and extend a systematic review of the evidence for ACG to
determine its effects on physical and cognitive health in older adults. Data Sources: MEDLINE, EMBASE, CENTRAL in the Cochrane Library, and PsycINFO databases
were searched from the date of the previous review (2011) to May 2016. Study
Selection: Eligible articles were randomized controlled trials (RCTs)
investigating the effect of ACG in adults aged 65 and older. Data Extraction:
Thirty-five studies were eligible for inclusion. Two review authors independently
conducted data extraction, risk-of-bias assessment, and coding of behavior change
techniques. Outcomes of interest were analyzed as continuous data and pooled as
standardized mean differences (SMD) and 95% confidence intervals (CI). The
Grading of Recommendations Assessment, Development, and Evaluation (GRADE)
approach was used to determine the quality of the evidence. Data Synthesis:
Behavior change techniques (N = 106) were coded in the included studies (mean =
3.02). Data were pooled for 5 main outcomes of interest. Significant moderate
effects in favor of ACG were observed for balance (SMD = 0.52, 95% CI = 0.24 to
0.79; 17 studies; 743 participants), for functional exercise capacity when
intervention delivery was >120 minutes per week (SMD = 0.53, 95% CI = 0.15 to
0.90; 5 studies; 116 participants), and for cognitive function (SMD = -0.48, 95%
CI = -0.80 to 0.17; 8 studies;
459 participants). There was no significant effect
observed for functional mobility or fear of falling. Limitations:
The quality of
the evidence for all comparisons was graded low or very low. Conclusions: At
present there is very little confidence that ACG improves physical and cognitive
outcomes in older adults.
