Limitations
Study participants were inpatients and subject to many constraints, not the least of which is how long they were able to remain on the inpatient unit. As such, some factors could not be controlled as closely as would have been ideal. The sample size was small but appropriate to determine feasibility of providing supplemental therapy during the inpatient stay – which was a primary study objective. The study was not powered to fully explore the extent of differences between the two modalities – which would require a much larger cohort and/or more tightly controlled groups, at least for the current study measures. Post-hoc estimates for study size were n=392 (for each arm, assuming a parity enrollment ratio) for the FIM score changes and standard deviations reported (
