Abstract
Objective: To determine the validity and reliability of the floor transfer test (FTT) in people with Parkinson's disease (PD). Methods: The sample was 25 subjects with PD. The concurrent and convergent validity of FTT was determined by correlation with scores of timed up and go test (TUG), movement disorder society- unified Parkinson's disability rating scale-III [motor component] (MDS-UPDRS), Schwab and England activities of daily living scale (SEADL). The intra rater reliability (ICC 3, 1), SEM, MDC, Bland & Altman limit of agreement (LOA) were determined. Results: FTT scores were positively correlated with TUG (rho= 0.59, p=0.02), MDS UPDRS III (rho= 0.69, p=0.001) and negatively correlated with SEADL (rho= -0.79, p=0.001) showing moderate concurrent and convergent validity. ICC (3,1) was 0.92, SEM and MDC were 1.28 and 3.54 respectively.
Conclusion: FTT is a valid and reliable tool to assess functional mobility in people with mild PD.
