💬In plain words
What the trial is, and whether it could suit you
The subjects will be asked to attend minimum 15 separate sessions, 6 for testing changes in reflex behaviors, 3 for testing changes in the influence of descending motor tracts on spinal motor neurons, 3 for each testing functional movement in response to a trip event and cross-tilt walking adaptation pattern, as part of their participation in the research study. The estimated amount of time to enroll and collect the data for each of the subjects is four months' time. The data will be analyzed and ready for grant preparation (if successful) in approximately four months after the start of the study.
