Objectives:
This study aimed to identify factors related to changes in walking performance in individuals 3 months after a stroke or TIA.
Design:
Cross-sectional study with post hoc analysis of a randomised controlled study.
Setting:
University Hospital, Sweden.
Participants:
79 individuals, 64 (10) years, 37% women, who were acutely hospitalised because of stroke or TIA between November 2016 and December 2018. Inclusion criteria were patients aged 18 or above and the major eligibility criterion was the ability to perform the 6 min walking test.
Intervention:
The intervention group received standard care plus daily mobile phone text messages (short message service) with instructions to perform regular outdoor walking and functional leg exercises in combination with step counting and training diaries. The control group received standard care.
Outcome Measures:
Multivariate analysis was performed and age, sex, group allocation, comorbidity, baseline 6 min walk test, body mass index (BMI), cognition and chair-stand tests were entered as possible determinants for changes in the 6 min walk test.
Results:
Multiple regression analyses showed that age (standardised beta -0.33, 95% CI -3.8 to -1.05, p<0.001), sex (-0.24, 95% CI -66.9 to -8.0, p=0.014), no comorbidity (-0.16, 95% CI -55.5 to 5.4, p=0.11), baseline BMI (-0.29, 95% CI -8.1 to -1.6, p=0.004), baseline 6 min walk test (-0.55, 95% CI -0.5 to -0.3, p<0.001) were associated with changes in 6 min walk test 3 months after the stroke event. The regression model described 36% of the variance in changes in the 6 min walk test.
Conclusions:
Post hoc regression analyses indicated that younger age, male sex, lower BMI and shorter 6 min walk test at baseline and possible no comorbidity contributed to improvement in walking performance at 3 months in patients with a recent stroke or TIA. These factors may be important when planning secondary prevention actions.
