ABSTRACT
Background
Higher physical activity levels during hospitalization may benefit the life-space mobility, defined as the ability to move within environments that expand from one’s home to the greater community, of stroke survivors following their discharge.
Objectives
This study aimed to evaluate the relationship between physical activity levels during rehabilitation hospitalization and life-space mobility among stroke survivors three months after their discharge.
Methods
We recruited 84 stroke survivors as prospective participants from four convalescent rehabilitation hospitals. Physical activity levels during hospitalization were assessed using pedometers with a three-axis accelerometer, and their average step count over 14 consecutive days prior to discharge was used as the representative set of values. Pedometers were placed on the participant’s waist or wrist on the non-paretic side. The Life-Space Assessment (LSA), a validated self-reporting measure for assessing community mobility, was implemented three months following participant discharge from rehabilitation hospitals via a mail-in survey method. To determine the relationship between the participants’ level of physical activity during hospitalization and the LSA score following discharge, we performed multivariate regression analysis.
Results
A total of 75 participants (89.3%) completed the post-discharge survey and were therefore included in the analysis. The multiple regression analysis, controlled for age, balance function, walking endurance, fear of falling, and functional status, revealed that daily step counts were significantly associated with the LSA score three months after discharge (β = 0.241, p = .026).
Conclusions
Physical activity levels during hospitalization were significantly associated with the life-space mobility of stroke survivors following discharge.
