Neurological examination findings to predict limitations in mobility and falls in older persons without a history of neurological disease

Abstract Purpose To estimate the prevalence of neurological signs and their association with limitations in mobility and falls in a sample of older persons without known neurological disease. Methods A neurologist examined 818 participants from the InCHIANTI study who were aged ≥65 years and who did not have cognitive impairment, treatment with neuroleptics, and a history of neurological disease. Mobility was assessed as walking speed and self-reported ability to walk at least 1 km without difficulty. Participants were asked to report falls that had occurred in the previous 12 months. Results Less than 20% (160/818) of participants had no neurological signs. Neurological signs were more prevalent in older participants and those with impaired mobility. When all neurological signs were included in sex-and age-adjusted multivariate models, 10 were mutually independent correlates of poor mobility. After adjusting for age and sex, the number of neurological signs was associated with progressively slower walking speed ( P P P Conclusion Neurological signs are independent correlates of limitations in mobility and falls in older persons who have no clear history of neurological disease.
