The original FRAC definitions were modified for the study. Falls were categorised by everyday tasks of increasing complexity completed at the time of the fall. Transfers/ changes in posture were categorised as ‘transitional’, everyday walking activities such as walking and carrying objects were ’combined’ and complex motor tasks including hill walking or skiing classified as ‘advanced’.
The study reported on inter-rater reliability (IRR) of the modified FRAC scale for people with incident idiopathic Parkinsons disease. 23 raters consisting of 3 clinical subgroups with clustered falls expertise rated 55 fall scenarios using the FRAC without formal training. Results demonstrated excellent IRR.
