Age-related variation in mobility independence among wheelchair users with spinal cord injury: A cross-sectional study

The Journal of Spinal Cord Medicine, 2016 · DOI: 10.1179/2045772315Y.0000000008 · Published: January 1, 2016

Simple Explanation

This study looked at how age affects the ability of wheelchair users with spinal cord injuries (SCI) to move around independently. The study found that as wheelchair users with SCI get older, they tend to be less independent in mobility-related activities. This decline in mobility independence seems to start in middle age and continues as people get older.

Study Duration

2011-2013

Participants

949 individuals with spinal cord injury using wheelchairs

Evidence Level

Cross-sectional community survey

Key Findings

1
Mobility independence decreases with age in wheelchair users with SCI across three domains: changing basic body position, transferring oneself, and moving around.
2
Men with SCI have higher odds of being independent in transferring oneself and moving around compared to women.
3
Participants with paraplegia have markedly higher odds of being independent in all mobility domains compared to those with tetraplegia.

Research Summary

This cross-sectional study assessed age-related variation in mobility independence among community-living wheelchair users with SCI. The study found a negative association between age and mobility independence across different mobility tasks, suggesting age-related decline occurs throughout adulthood. Longitudinal studies are needed to understand the underlying causes and mechanisms of functional changes over time and to develop preventive strategies.

Practical Implications

Anticipate Mobility Decline

Healthcare professionals should anticipate and proactively address potential mobility issues as wheelchair users with SCI age.

Promote Independence

Interventions should focus on maintaining the maximum level of achievable independence throughout the lifespan of individuals with SCI.

Address Sex Differences

Recognize and address the sex differences in mobility independence, particularly in transferring and moving around.

Study Limitations

1
Cross-sectional study design limits causal inferences.
2
Potential non-response bias and survival bias may affect the association between age and mobility independence.
3
SCIM items do not differentiate between needing a device and needing partial assistance.
