The Relationship Between Dual-Task Performance and Functional Independence in Stroke Patients

Abstract

Purpose: Dual-task performance have a role in independent motor functions such as gait and balance. Although walking and balance parameters are important in functional independence, the level of independence is a complex condition affected by many factors. The aim of this cross-sectional study is to investigate the relationship between dual-task performance and functional independence levels in stroke patients. Material and Methods: 26 hemiplegic patients were included in this research in a tertiary healthcare institution. The participants’ independence levels were evaluated by the functional independence mesasure(FIM). Single task performance, motor dual-task performance, and cognitive dual-task performance were evaluated by calculating walking time in a 10-meter walking test. The relationship between dual-task interference and functional independence level was examined by Spearman correlation analysis. Results: The motor dual-task interference was found as 0.7 (0.0-0.26) and the cognitive dual-task interference was found as 0.19 (0.05-0.38). There was a negative, moderate, and statistically significant correlation between the FIM score and the motor dual-task interference (r = -0.48, p = 0.01). However, no significant correlation was detected between FIM score and cognitive dual-task interference (p = 0.16). Conclusion: The level of functional independence in stroke patients is associated with motor dual-task interference. Rehabilitation programs that improve dual-task performance can increase the functional independence levels of stroke patients.
