Investigation of the Psychometric Properties of the Squares Test in Measuring Hand Function in Parkinson's Disease

The first aim of the present study was to investigate reliability, validity and responsiveness to the minimal clinically important difference, which is defined as the smallest change in score corresponding to clinically meaningful change realized by patient, of the squares test in people with PD.

The second aim of the study is to determine the relationship between hand function and both trunk control and balance in PD population.

About this study

At baseline, the ST, Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn and Yahr (H&Y) Scale, Berg Balance Scale (BBS) and Trunk Impairment Scale (TIS) was applied to the PS group when the patients were "on" period. The ST was repeated after seven days from the first application when PD group were "on" period to evaluate its reliability.

Treatment and study plan

The squares test

Other

The squares test (ST) originally used in handedness is modified. The ST is a reliable, not time-consuming and easy to administer test for evaluated hand function.

Primary outcomes

  1. The Squares Test

    Time frame: 2 minutes

    The Squares Test is used to evaluate hand function.

Secondary outcomes

  1. The Nine-Hole Peg Test

    Time frame: 2 minutes

    The Nine-Hole Peg Test is used to evaluate hand function.

  2. Berg Balance Scale

    Time frame: 15 minutes

    Functional balance performance was assessed with the Berg Balance scale.

  3. Trunk Impairment Scale

    Time frame: 20 minutes

    Trunk control was assessed by the Trunk Impairment Scale.
