- Brief Summary
Background: The majority of stroke survivors regain walking ability. However, the ability to adapt gait patterns to meet environmental demands remains impaired in a majority of people in the chronic phase after stroke. This impaired gait adaptability has a profound impact on activities of daily living and quality of life. Treatment targeting gait adaptability is therefore critical for safe and independent community ambulation in people with stroke. Augmented or virtual reality in rehabilitation programs can be used to train gait adaptability in a controlled situation. A few studies have evaluated gait adaptability training in people with stroke. Although results were promising, these studies did not include an adaptability-related outcome measure, or were limited to uncontrolled or small-scaled pilot studies. Moreover, it is unknown if beneficial training effects can be fostered for 1 year after completion of a training program. We evaluate the short-term effects of a 5-week gait adaptability training in an adequately powered, waiting-list controlled clinical trial \[ref naar clin trial nummer\]. In the current study, we focus on the retention of potentially beneficial effects of this 5 week gait adaptability training program. We will evaluate if short-term effects of gait adaptability training can be retained through single training sessions to boost performance, or by an home exercise program. We hypothesize that booster sessions and home-based exercise will both yield better retention of training effects at 1 year follow-up as compared to the control arm without an experimental intervention.
Objective: The primary objective of this study is to test the hypothesis that retention of training-induced gains in gait adaptability can be fostered by providing booster sessions or by prescribing home-based training.
Study design: Explorative randomized study, comparing the effect of 3 1-hr booster training sessions against home-based exercise against no intervention on gait adaptability performance 1 year after completion of a 5-week gait adaptability training program.
Study population: Stroke patients in the chronic phase after stroke, who completed the 5-week gait adaptability training using the C-Mill and agreed to continue in this follow-up study. We expect this to be 50-75 participants.

Group Intervention Description Booster group Gait adaptability training Participants assigned to the booster group will receive a three single training sessions 3 months apart targeting gait adaptability using the C-mill. Assessments will take place after giving informed consent which is indicated as the start of the study (baseline), 6 months and 12 months post-baseline. Home-based exercise group Home-based exercise training Participants assigned to the home-based exercise group will receive a program for training at home aiming at a minimum training time of 60 minutes per week. Assessments will take place after giving informed consent which is indicated as the start of the study (baseline), 6 months and 12 months post-baseline
- Primary Outcome Measures
Name Time Method Walking Adaptability Ladder Test (WALT) score 12 months post-baseline Measure of gait adaptability. An adapted version for adults of the Walking Adaptability Laddertest for Kids (WAL-K) to assess the ability to flexibly adjust the gait pattern during overground walking. Outcome is based on performance time and foot placement errors measured in seconds where a lower score is a better outcome.
Emory Functional Ambulation Profile (EFAP) score 12 months post-baseline Measure of gait adaptability. In this task the participants traverse a standardized 5m obstacle course. Outcome is time to perform the task measured in seconds where a lower score is a better outcome
- Secondary Outcome Measures
Name Time Method Lab-based walking adaptability test 12 months post-baseline Measure of gait adaptability. Target stepping task using the Gait Real-time Analysis Interactive Lab (GRAIL) where participant must step on projected stepping stones as accurately as possible. Step width and step length between the stepping stones will vary.
Balance performance 12 months post-baseline Measure of gait stability, measured by the margin of stability (meter) and the center of mass excursion (meter), on treadmill walking with perturbations using the Gait Real-time Analysis Interactive Lab (GRAIL).
Walking performance 12 months post-baseline Measure of walking ability using the 10meter walktest, measured in seconds where a lower score is a better outcome.
Balance confidence 12 months post-baseline Evaluating balance confidence using the Activity Balance Scale, measured on a 0% - 100% scale, where a higher score is a better outcome.
Daily life gait performance as assessed by gait quality 12 months post-baseline Measured by inertial measurement units placed on both feet and the lower back. Analysis through cusomized algorythms.
Daily life walking activity assessed by walking time per day 12 months post-baseline Average time of walking during the day (minutes) measured in one week using the Activ8.
Health-related quality of life 12 months post-baseline Evaluating the disability and health-related quality of life after stroke using the Stroke Impact Scale mobility subscale, measure on a 5-point scale ("could not do at all = 1" - "not difficult at all = 5") where a higher score is a better outcome.
Balance performance through MiniBESTest 12 months post-baseline Measure of balance and gait stability using the Mini Balance Evaluation Systems Test (MiniBESTes). Tasks are score on a 3-point scale. Outcome is an average score ranging between 0 and 1 where a higher score is a better outcome.
