Beneficial Falls in Stroke Patients：Reliability and Predictive Validity of the Judgement Checklist / The Japanese Journal of Rehabilitation Medicine

ABSTRACT

Objective：The purpose of this study was to determine the reliability and predictive validity of the Judgement checklist for beneficial falls (hereafter called“Judgement checklist”) in stroke patients.Methods：Five raters evaluated the Judgement checklist for 20 fallers with stroke, and two raters reevaluated the same patients. Fleiss' Kappa and Cohen's Kappa for examination of inter-rater and intra-rater reliability were calculated. For predictive validity, beneficial fallers were identified from among 123 fallers with stroke, using the Judgement checklist. We compared the incidence rate of recurrent falls and motor Functional Independence Measure (FIM) in beneficial fallers and other fallers.Results：Fleiss' Kappa for Judgement was 0.838, and Cohen's Kappa was 1.000. Inter-rater and intra-rater reliability for the Judgement checklist was high. The rate of recurrent falls in beneficial fallers was significantly lower than that in other fallers. The motor FIM in beneficial fallers was significantly higher than that in other fallers, and beneficial fallers tended to have above average ability to recover.Conclusion：The reliability and predictive validity of the Judgement checklist were shown to be high. The Judgment checklist was effective in evaluating the quality of falls and was useful for patient instruction after a fall.
