PURPOSE: To examine the test-retest reliability of spatio-temporal gait
parameters during performance of single- and dual-tasking in post-stroke
patients. METHOD: This study was conducted using a single-group repeated-measures
design, involving a baseline measurement session and a follow-up session two days
later. Forty-three chronic stroke patients (>6 months) participated in this
study. Spatio-temporal gait parameters under the single- and dual-task conditions
at a self-selected comfortable gait speed were measured using the GAITRite
walkway system. Intraclass correlation coefficients [ICC(2,1)] were calculated
for determination of reliability between sessions. The level of agreement between
the two sessions was determined using Bland-Altman 95% limits of the agreement
plots. RESULTS: In all gait parameters, a significant difference was observed
between the single- and dual-task conditions (p < 0.05). For the single
condition, ICC (95% CI) was very good for all measures, ranging from 0.98 to 0.99
(0.97-0.99). In addition, for the dual-task condition, ICC (95% CI) was good to
very good for all measures, ranging from 0.69 to 0.90 (0.49-0.99). CONCLUSIONS:
The results of current study demonstrated that the test-retest reliability of the
GAITRite system for measurement of spatio-temporal gait parameters under single-
and dual-task conditions was good to very good. Therefore, we suggest that
measurement of spatio-temporal gait parameters under a dual-task condition using
the GAITRite system would be useful for clinical assessment in post-stroke
patients. IMPLICATIONS FOR REHABILITATION: Improvement of walking ability
provides opportunities for stroke patients to participate in the community. Our
finding, additional cognitive tasks can interfere with the independently basic
activities of daily living in stroke patients, may provide basic information for
use in development of rehabilitation programs for stroke patients.
Spatio-temporal gait parameters under the dual-task condition measured using the
GAITRite system may be useful for clinical assessment in post-stroke patients.
