The risk of falling in young adults with neurological conditions: a systematic review.

PURPOSE

To review systematically the literature on fall risk factors for young patients affected by neurological disorders.

METHOD

A systematic search of all primary research-based literature on risk factors for falls or fall characteristics in young adults (mean age <55 years) published prior to July 2012 was conducted using 11 databases. Studies that focused on fall risk screening tools, fear of falling or interventions for fall prevention were excluded. Two reviewers independently agreed on eligibility and methodological quality and extracted data.

RESULTS

Twenty-three final studies were selected, including 21 observational studies; one randomised controlled trial and one qualitative study. An average of 50.2% of the 2776 total participants experienced at least one fall. Among the multiple risk factors studied, a reduced performance in balance and gait was consistently associated with falls, while the contribution of single physical and cognitive impairments was variable in different populations. Walking aids, wheelchair characteristics and environmental hazards are significant environmental risk factors. The heterogeneity of the assessment tools used to measure risk factors limited comparison across studies.

CONCLUSION

Falling is a common problem among young patients affected by neurological disorders, although the risk of falling for a specific individual is difficult to predict and the risk of a severe fall-related injury has not yet been established.

IMPLICATIONS FOR REHABILITATION

Young patients with impaired gait and balance or medium to severe motor disability appear to be at increased risk of falling. Patients who are relatively independent and still participating in challenging activities have an increased exposure to fall-risk. Walking aids, wheelchair characteristics and environmental hazards are significant environmental risk factors. These risk factors should be monitored closely in the young neurological population to help prevent falls.
