Investigating the optimal reactive balance training intensity in people with chronic stroke: Study protocol for a...

Area of Science:

• Neurorehabilitation
• Biomechanics
• Clinical Trials

Background:

• Stroke frequently causes impaired balance, increasing fall risk and disability.
• Reactive balance training (RBT) improves stepping responses to perturbations, reducing fall risk.
• Optimal RBT intensity for chronic stroke survivors is not yet established.

Purpose of the Study:

• To determine the optimal intensity of RBT for individuals with chronic stroke.
• To compare high-intensity RBT, moderate-intensity RBT, and a walking control group.
• To assess the long-term effects of RBT intensity on balance and fall risk.

Main Methods:

• Assessor-blinded randomized controlled trial with 63 chronic stroke participants.
• Four days of consecutive training comparing high-intensity RBT, moderate-intensity RBT, and walking control.
• Outcomes measured pre-training, post-training, and at one-year follow-up.

Main Results:

• Primary outcome: reactive stepping ability (steps to recover balance).
• Secondary outcomes: adverse events, functional balance, falls efficacy, daily activity participation.
• Hypothesis: High-intensity RBT leads to faster adaptations and better retention.

Conclusions:

• Findings will inform clinical guidelines for stroke rehabilitation.
• Optimizing RBT intensity can enhance therapy efficiency and patient outcomes.
• Reduced fall risk and improved functional independence are key goals for stroke survivors.
