Abstract:
Background: Reliable balance measures are crucial for effective stroke rehabilitation.
Purpose: This study examines the between-day and within-day reliabilities of the center of pressure (CoP) measures in chronic stroke survivors in different standing positions under the influence of motor and cognitive dual-tasking.
Methods: Sixteen people (49.31±15.5 years, five females) with chronic stroke were assessed in two sessions, 48 hours apart. Participants completed three balance control conditions: single-task, motor dual-task, and cognitive dual-task, while they performed three trials of open-eye quiet standing and semi-tandem standing. Three trials of closed-eye quiet standing were conducted in the single-task condition. A two-way random model of the Intraclass correlation coefficient (
Purpose: This study examines the between-day and within-day reliabilities of the center of pressure (CoP) measures in chronic stroke survivors in different standing positions under the influence of motor and cognitive dual-tasking.
Methods: Sixteen people (49.31±15.5 years, five females) with chronic stroke were assessed in two sessions, 48 hours apart. Participants completed three balance control conditions: single-task, motor dual-task, and cognitive dual-task, while they performed three trials of open-eye quiet standing and semi-tandem standing. Three trials of closed-eye quiet standing were conducted in the single-task condition. A two-way random model of the Intraclass correlation coefficient (
Results: Within-day ICC values were higher than between-day values (ICC: 0.78- 0.96). Mean velocity and mean and SD of velocity in the AP direction showed the highest relative and absolute reliabilities in an open-eyes quiet standing position (ICC: 0.82- 0.92, SEM: 0.67- 1.24). Dual-tasking could increase the reliability of the CoP measures, except for the sway area (ICC: 0.53- 0.93 changed to 0.84-0.96). MDCs ranged from 1.03 to 7.77 mm/s for velocity-based variables.
Conclusions: Assessing the postural control system during dual-task conditions provides more reliable CoP measures, especially in a semi-tandem standing position. These findings can provide clinicians valuable insights into detecting specific balance problems post-stroke individuals encounter.
