Fall Risk Assessment and Prevention in Older Adults

Falls are a leading cause of injury, hospitalisation and loss of independence among older people, affecting physical and psychological well-being across diverse populations. Risk emerges from an interplay of intrinsic factors—such as muscle weakness, impaired balance, gait disturbances, sensory deficits and chronic comorbidities—and extrinsic factors including environmental hazards, polypharmacy and social determinants. Traditional assessment relies on clinical performance tests (for example, the Timed Up and Go test and the sit-to-stand test), observational gait analysis and, increasingly, sensor-based measures of postural sway and gait variability. Advances in digital motion analysis and wearable technology now allow objective quantification of balance and mobility in real-world settings. Prevention strategies are multifactorial, combining tailored exercise programmes (notably strength and balance training), home hazard modification, medication review and vision correction, supported by community-based education. Evidence demonstrates that structured group or home-based interventions can reduce fall incidence and related injuries. Translating these findings into practice requires interdisciplinary collaboration, integration of novel assessment tools into care pathways and policy support to ensure equitable access to preventive services. Future research aims to refine predictive algorithms, address health disparities in fall outcomes and develop scalable models that link mechanistic insights with population health approaches.

Fall Risk Assessment and Prevention in Older Adults publication trend

The graph below shows the total number of articles in fall risk assessment and prevention in older adults across all publications each year (not limited to Nature Index journals).

Technical terms

Gait variability: The stride-to-stride fluctuations in walking patterns that reflect the stability and adaptive control of locomotion.

Timed Up and Go test (TUG): A standardised assessment in which an individual stands from a chair, walks three metres, turns, returns and sits, used to gauge mobility and fall risk.

Sit-to-stand test: A functional performance measure involving repeated transfers between sitting and standing positions to assess lower limb strength and dynamic balance.

Digital motion analysis: The use of sensors or video capture to obtain objective, quantitative metrics of movement kinematics and postural control.

Disability-adjusted life years (DALYs): A population health metric combining years of life lost due to premature mortality with years lived with disability.
