Parkinson Hastalarında Aktivlim Ölçeğinin Psikometrik Özelliklerinin Araştırılması

Abstract

The aim of this study was to investigate whether ACTIVLIM scale a valid and reliable scale for activity limitations of patients with parkinson's and to investigate sensitivity to changes in the activity limitations. The study was carried out with 94 voluntary patients with Parkinson's disease who have been directed to be given home exercises or for physiotherapy. Patinets between the ages of 35-95 years, without any orthopedic problems that affect activities of daily living, without any serious neurological disease other than Parkinson's disease, Modified Hoehn&Yahr score ≤4 and who agreed to participate in the study were included. Patients first was evaluated by both ACTIVLIM and UPDRS, two weeks later just with ACTIVLIM, 8 weeks later by both of them by the same physiotherapist. They were given a home exercise programme after the initial assessment. Internal consistency, test-retest reliability, content validity (Comparing with the UPDRS-ADL), construct validity and responsiveness of ACTIVLIM scale were investigated by the data obtained in patients with Parkinson's. ACTIVLIM has been found to be highly reliable and valid instrument for measuring activity limitations in Parkinson patients (ICC=0.998, Cronbach α=0.938, Content validity rs= -0.719). ACTIVLIM wasn't sensitive to the changes in activity limitations compatible with UPDRS-ADL subsection that we accepted as a reference scale for changes. However, because of the resulting changes in activity limitations were very low (UPDRS-ADL Cohen's d=0.07), in future studies it is needed to investigate the sensitivity of ACTIVLIM scale again by obtaining clinically significant effect size on the UPDRS-ADL subsection. "Sit toilet bowl" item was in the structure of the 18-item ACTIVLIM scale translated into Turkish shows incompatibility with lifestyle and architecture of our country, it should be kept in the scale with a more appropriate translation. "Get out of the bathtub" item should be replaced with a new item that has similar level of difficulty for social adaptation.
