Predictive Ability of Fahrenheit, a Hand Motion Recording System for Assessing Hand Motor Function in Patients with Hemiplegia Post-Cerebrovascular Disease—A Pilot Study

The Brunnstrom recovery stage (BRS) assessment is a frequently used clinical instrument, but does not allow temporal or spatial analysis owing to its use of binary assessments. We developed kinematic system (Fahrenheit) that employs three-dimensional motor using the Leap Motion Controller as an infrared camera assess hand function in patients post- cerebrovascular disease (CeVD)/stroke, according BRS criteria. investigated whether Fahrenheit could predict outcome post-CeVD with hemiplegia. Thirty-two inpatients CeVD were recruited this pilot study. Participants’ after was assessed through their performance nine tasks assessment. constructed receiver operating characteristic (ROC) curve based on each participants’ performance, and compared results computed area under (AUC) for ROC curve. All task values showed significant differences between sufficient insufficient movements. AUC analyses had high predictability (all ≥ 0.7), which comparable those therapists’ Measurements respect criteria, indicating may have application assessing finger movement functions. Further verification involving more required ensure becomes reliable evaluation tool.
