- Abstract
Purpose: Lower extremity physical function (LEPF) is a key component for mobility and is impacted in stroke-related disability. A reduction in LEPF can have a significant impact on an individual's Quality of Life (QoL). The aim of this study is to characterise the relationship between LEPF and QoL. Methods: The MOBITEC-Stroke Study is a longitudinal cohort-study including patients with their first occurrence of ischaemic stroke. Using a linear mixed-effects model, the relationship between LEPF (timed up-and-go performance (TUG); predictor) and QoL (Stroke Specific Quality of Life scale (SS-QoL); outcome) at 3 and 12 months post stroke was investigated and adjusted for sex, age, Instrumental Activities of Daily Living (IADL), fear of falling (Falls Efficacy Scale-International Version, FES-I), and stroke severity (National Institute of Stroke Severity scale, NIHSS), accounting for the repeated measurements. Results: Data of 51 patients (65 % males, 35% females) were analysed. The mean age was 71.1 (SD 10.4) years, median NIHSS score was 2.0. SS-QoL was 201.5 (SD 20.5) at 3 months and 204.2 (SD 17.4) at 12 months; the mean change was 2.7 (95% CI -2.4 to 7.7), p= 0.293. A positive association was found between baseline TUG performance (estimate log score -13.923; 95% CI -27.495 to -0.351; p=0.048) and change in SS-QoL score in multivariate regression analysis. Conclusion: Higher LEPF (i.e better TUG performance) at baseline, was associated with an improvement in QoL from 3- to 12-months post stroke. These results highlight the critical role of physical function, particularly baseline LEPF, in influencing the QoL of stroke survivors. Summary: Lower extremity physical function (LEPF), which is a measure of mobility, affects the quality of life in people who have had a stroke. Understanding this relationship can help improve stroke survivors' recovery and well-being. This study sought to understand the connection between mobility, specifically lower extremity physical function, and the quality of life in individuals after a stroke. The study's primary focus is to explore and characterize how LEPF relates to the quality of life in stroke patients over time, particularly between 3- and 12-months post-stroke. It was found that better physical function (measured by the timed up-and-go test) at the beginning of the study was linked to improved quality of life after 12 months. This suggests that early improvement in mobility, particularly lower extremity physical function can have a positive impact on the overall quality of life for stroke survivors.
