Assesses whether exercise reduces falls, recurrent falls, or injurious falls in people living with dementia (PWD). Finds insufficient evidence to support exercise as an effective fall prevention strategy in PWD, highlighting the need for better-designed research.

Examines sex differences in fall risk among older adults who had already experienced a fall. Results show that men experienced more falls than women, with poorer executive function being a key predictor of falls in men. Findings suggest the need for sex-specific fall prevention strategies that consider both physical and cognitive factors.

Examines the cost-effectiveness of the Otago Exercise Programme (OEP), from a health care system perspective, among older women and men who have previously fallen. Finds that the OEP significantly reduced falls among men but not women, there was no overall gender interaction effect, and it did not improve quality of life in either group.

Highlights the health benefits of exergaming—a technology-based form of exercise—for office workers. Demonstrates that exergaming can improve physical function, mental health, and cognition, while reducing pain and chronic disease risk.

Compares the effects of traditional balance training (BT), virtual reality balance training (VR), and a combined exercise program (MIX) on fall risk factors in older men. Findings suggest that combining exercise modes (MIX) is the most effective strategy for reducing fall risk in older men.
