Summary
Fear of falling is linked to gait instability in multiple sclerosis (MS) patients. This association is particularly evident in dual-task walking conditions one year after initial assessment.
Area of Science:
- Neurology
- Rehabilitation Science
- Movement Disorders
Background:
- Behavioral symptoms and gait disturbances are prevalent in multiple sclerosis (MS).
- Gait instability significantly impacts the quality of life and independence of MS patients.
Purpose of the Study:
- To investigate the relationship between fear of falling and gait instability.
- To assess this association at a one-year follow-up in individuals with MS.
Main Methods:
- Thirty-five MS patients participated in the study.
- Fear of falling was measured using the Fall Efficacy Scale-International.
- Gait variability, specifically stride time variability, was assessed under single and dual-task conditions at baseline and one year.
Main Results:
- A higher baseline fear of falling score correlated with increased stride time variability at the one-year mark.
- This association remained significant even after adjusting for other relevant factors (covariates).
- The link between fear of falling and gait variability was more pronounced under dual-task conditions.
Conclusions:
- Fear of falling is a significant predictor of gait variability in MS patients over a one-year period.
- Dual-task conditions exacerbate the association between fear of falling and gait instability.
- These findings highlight the importance of addressing fear of falling in managing gait disorders in multiple sclerosis.
