NCT05772936

Brief Summary

The purpose of this study is to investigate the effectiveness of reactive step training on the timing and frequency of perturbation induced paretic leg stepping in persons post stroke. The study will consist of one or six one-hour training sessions and a pre and post visit each lasting up to two hours at our downtown Chicago location.

Outcome Measures

Primary Outcomes (3)

  • Change in frequency of stepping with paretic leg after a perturbation

    number of trials when the paretic leg takes the first reactive step after the perturbation is applied during the reactive trials.

    Change in stepping with paretic leg will be modeled from baseline and immediately after the intervention.

  • Change in step onset time for voluntary and reactive steps

    step onset time is the time the stepping foot lifts off the ground after the Go cue for voluntary steps and after the perturbation for the reactive steps.

    Change in step onset will be modeled from baseline and immediately after the intervention.

  • Change in reactive lean balance test

    Lean balance test is a passive way to test reactive stepping. Participants will lean again the research staff hands until their center of mass is at the edge of their feet. The research staff will suddenly remove their hands and allow the participant to catch their balance. Research staff are trained to perform the test and to guard the participant if needed. Extra personnel will be near by for additional support if the participant is not able to recover their balance.

    Change in reactive lean balance test will be modeled from baseline and immediately after the intervention.

Secondary Outcomes (2)

  • 10 meter walk test

    Day 1 before training

  • Activities-specific Balance Confidence scale (ABC)

    Day 1 before training

Study Arms (1)

single arm non-randomized

EXPERIMENTAL

all enrolled subjects will participate in the perturbation-induced step training, 1 or 6 sessions about 1-1.5 hour (30-90 trials) each session.

Behavioral: Balance training

Interventions

perturbation induce step training to improve reactive stepping with paretic leg.
