Can gentle balance challenges help stroke survivors walk better?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Admitted to one of the listed study locations for inpatient rehabilitation following a stroke. * Be 18 years of age or older. * Have at least a moderate fall risk or better, shown by an admission Berg Balance Scale (BBS) score of 21/56 or greater. * Patients that score below 21 or are non-ambulatory will not be considered for this study. * Patients that are emergently re-admitted to acute care and subsequently re-admitted to the stroke rehabilitation program will be reassessed for appropriateness of continuation in the study on a case by case basis. * Patients that progress to a BBS score of 21 or greater during their stay, and have a set discharge date of 10 days or longer, can be approached for study recruitment. * Appropriate cognition * Able to read and understand the consent, in English or a language available by translator services, based on the judgement of the clinical team, either by using outcomes measures, i.e. SLUMS greater than or equal to 20, or through clinical evaluations and team discussion. Eligibility will ultimately be decided by the treating physician in combination with the participant's clinical team. * Ability to tolerate and actively participate in up to six, 30-minute sessions, with physical therapy while using the BWSS. * Weigh less than 450 pounds, per the structural limitations of the ZeroG system. Exclusion Criteria: * Active seizures * Spinal stabilization with the use of Halos * Uncontrolled hypertension or hypotension * Unstable skin structures (i.e. skin grafts) * Chest tubes * Unstable rib or lower extremity fractures * Severe osteoporosis * Participants where pressure around the abdomen, thighs, groin, or shoulders in contraindicated * Cognitive deficits that would disrupt the ability to provide informed consent as described above * Active enteric infection control precautions * Subjects would be eligible once precautions are lifted * Ongoing orthostasis * New limb amputations * Vestibular disorders that may impact balance * Premorbid conditions that may impact balance * Patients requiring more than 50% high flow oxygen as consistent with inpatient therapy guidelines * Anyone belonging to a vulnerable population, including inmates, individuals under the age of 18, and who are or might be pregnant
