Conditions
Summary
The goal of this clinical trial is to evaluate the effect of a 4-week perturbation-based balance training with and without targeted Neuromuscular electrical stimulation on neuromechanic gait fall risk predictor and reactive balance. The aim of this study is to investigate whether a 4-weeks perturbation-based balance training can improve kinematic and spatiotemporal parameters of reactive balance control, and kinematic and neuromuscular gait parameters, described as early fall risk predictors, in persons with stroke. Additionally, a second aim is to determine whether an impairment-oriented intervention aimed to correct the gait patterns during the proposed walking perturbation training, using a targeted neuromuscular electrical stimulation (NMES) applied to the rectus femoris and tibialis anterior muscles, could enhance the potential benefits of the proposed training protocol among stroke population.
Eligibility
Inclusion Criteria1
- Healthy participants will be included if they passed a cognitive test (> 26/30 on Montreal Cognitive Assessment Scale) and finish a six-minute walk test independently (to ensure that these individuals can walk without balance or gait impairments)
Exclusion Criteria1
- Healthy individuals will be excluded if they self-reported any neurological, musculoskeletal, or other systemic disorders that would affect the participant's locomotion.

Interventions
Participants will be asked to walk over a six by two meters computer-controlled movable platform at a self-selected speed. Slip-like perturbations will be induced by the device software that moves the platform 12 inches forward at 0.46 m/s with an acceleration of 9.4 m/s2. Participants will be secured in a safety harness which will be attached to the overhead arch of the platform. Participants will be asked to go to the experimental study cite 11 times. A baseline screening, 8 training sessions, a post-training screening, and a 2 months folow up screening
NMES will be applied on tibialis anterior and quadriceps muscles during perturbation-based balance training.
