Gait Recovery in Patients After Acute Ischemic Stroke (GAITFAST)

July 27, 2022 updated by: Barbora Kolarova, University Hospital Olomouc

GAIT Recovery in Patients aFter Acute Ischemic STroke: A Randomized Comparison of Robot-assisted and Therapist-assisted Gait Training on a Treadmill.

More than 80% of ischemic stroke (IS) patients have some walking disability, which restricts their independence in the activities of daily living. Physical therapy (PT) significantly contributes to gait recovery in patients after IS. However, it remains unclear, what type of gait training is more effective and which factors may have impact on gait recovery. Two hundred fifty IS patients will be enrolled to undergo a 2-week intensive inpatient rehabilitation including randomly assigned robot-assisted treadmill gait training (RTGT) or therapist-assisted treadmill gait training (TTGT). A detailed clinical and laboratory assessment of gait quality, as well as the degree of neurological impairment, quality of life, cognition and depression will be performed in all patients during the study. We hypothesize that these variables may also affect gait recovery in patients after IS. In a randomly selected 60 enrolled patients, a multi-modal magnetic resonance imaging (MRI), including functional MRI, will be performed to assess neural correlates and additional predictors of gait recovery.

Study Overview

Detailed Description

One hundred twenty consecutive first ever ischemic stroke patients classified as dependent walkers (Functional Ambulatory Category interval <1,3>) will be enrolled in the randomized blinded single center prospective clinical trial GAITFAST with a randomization either for robot-assisted treadmill gait training (RGT) or therapist-assisted treadmill gait training (TTGT) after acute phase (5-10 days after stroke onset). All enrolled patients will undergo a 2-week intensive inpatient rehabilitation including randomly assigned TTGT or RTGT followed with clinical visits (at the beginning of inpatient rehabilitation, at discharge, and three and six months after enrollment in the study). Each clinical visit will include detailed clinical functional assessments, assessment of spatiotemporal and kinetic gait parameters, assessment of neurological impairment, assessment of quality of life, cognition and depression. In 60 randomly selected enrolled IS patients, a repeated multi-modal magnetic resonance imaging (MRI) including functional MRI (fMRI) will be performed during the study follow-up to identify brain structures with possible impact on gait recovery.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in gait speed during overground walking
Time Frame: Baseline (before beginning of inpatient RHB), after two weeks (at the end of inpatient RHB), and in follow-up (after three and six months after stroke onset)
Gait speed will be measured using the 10 Meters Walking Test (performance measure used to assess walking speed in meters per second over a short distance). The subject will be asked to walk for a distance of 10 meters at his/her comfortable speed. The time will be measured for the distance of the middle six meters, which will allow walk acceleration and deceleration. Each patient will perform two trials with a calculation of mean time value. If physical assistance of another person (to prevent a fall or collapsing) is needed for a patient to complete the test, the level of assistance provided will be documented. Usage of any assistive device and/or bracing (that patients are currently using for walking and are needed to complete the test) will be also documented.
