Effectiveness of increased occupational therapy using propensity score matching for patients with impaired consciousness in the acute stage of cerebral hemorrhage

Abstract

[Objective] The purpose of this study was to evaluate the effect of increasing the duration of occupational therapy (OT) for patients with cerebral hemorrhage and impaired consciousness. [Methods] The study design was a non-randomized controlled trial, and the experimental group received 20 minutes more OT than the control group. The subjects were 86 patients with JCS II-digit cerebral hemorrhage (43 patients in each group). The survey items were 17 baseline characteristics that were presumed to be associated with the rate of improvement to JCS I digits. Statistical analysis was performed by log-rank test after propensity score matching. [Results] The cumulative residual rate of impaired consciousness was observed to be lower in the experimental group, but the difference was not significant. [Conclusion] There was no significant difference in the effect of 20 minutes of additional OT on the improvement of disorientation, but this may be due to insufficient sample size.
