Gait Stability After Stroke (AdaptGait)

Influence of Added Tasks and Different Environmental Conditions on Gait Stability After Stroke

The study will investigate gait stability in individuals post-stroke compared with age- and sex-matched healthy adults. Participants will undergo laboratory-based walking assessments under different environmental conditions, including level walking, uphill and downhill walking, and unexpected slip perturbations, with and without added cognitive, postural, and load-carrying tasks. The primary outcome measures will be the Margin of Stability (MOS), step width, and step width variability.

Detaljerad beskrivning

: The study will recruit 20-30 adults post-stroke and an equal number of healthy controls. Participants post-stroke will be recruited after discharge from their regular rehabilitation. Participants will complete a single assessment session involving walking on a instrumented dual-belt treadmill mounted on a Stewart platform while secured with a safety harness. Walking conditions will include level, inclined, declined, and slip-perturbed walking, as well as walking combined with serial subtraction, head turning, or backpack carrying. Three-dimensional motion capture, force measurements, and surface electromyography will be used to quantify gait biomechanics and neuromuscular responses. The effects of environmental conditions and added tasks on gait stability, balance control, and fall risk will be compared between groups to identify biomechanical and neuromuscular markers associated with increased fall susceptibility after stroke.

Intervention / Behandling
Aktiv komparator: Post-stroke patients

Adults with unilateral stroke (>3 months post-stroke) will undergo assessment of gait stability and balance responses during treadmill walking under different environmental conditions (level, uphill, downhill, and slip-perturbed walking) and added tasks (serial subtraction, head turning, and backpack carrying).

Level treadmill walking

Uphill treadmill walking

Downhill treadmill walking

Slip-perturbed treadmill walking

Added task: serial subtraction

Added task: head turning

Added task: backpack carrying

Aktiv komparator: Control group: healthy control participants

Age- and sex-matched healthy adults will undergo the same assessment protocol as the post-stroke patients, i.e., assessment of gait stability and balance responses during treadmill walking under different environmental conditions (level, uphill, downhill, and slip-perturbed walking) and added tasks (serial subtraction, head turning, and backpack carrying).
