Table 1 Assessments used in the study reflecting the component body structure of the International Classification of Functioning, Disability and Health

National Institutes of Health Stroke Scale

The National Institute of Health Stroke Scale is a score system to quantify the impairment caused by a stroke. The sum of the values from the investigations results in a maximum of 42 points. The higher the score, the more extensive the stroke [7].

Fugl-Meyer Assessment (upper extremity)

The section motor function of upper limb is one of five domains, a three-point scale is used for rating performance as 0 = cannot perform, 1 = performs partially and 2 = performs fully, maximal possible score: 66 points [15].

Grip and pinch strength

A dynamometer is used to measure grip strength and a pinch gauge to measure pinch force.

Montreal Cognitive Assessment

The Montreal Cognitive Assessment is a screening assessment for detecting cognitive impairment, a maximum of 30 points (no restrictions) can be achieved [30].

Line Bisection Test

The line bisection test is a test to detect the presence of unilateral spatial neglect. To complete the test, the middle of several horizontal lines is estimated and marked [1, 2].

Bells Test

The Bells test is a cancellation task used for quantitative and qualitative evaluation of visual neglect. Patients are asked to find bells that are distributed pseudo-randomly among distractive stimuli [16].

Aphasia Test

Standardized test for differential diagnosis Aphasia - no aphasia [26].

Apraxia Screen of TULIA

The Apraxia Screen from TULIA is a short assessment to diagnose apraxia with 12 hand movements, dichotomous scale: 0 = not fulfilled, 1 = fulfilled motion task based on the comprehensive standardized Test for Upper-Limp Apraxia (TULIA) [42].

ASKU self-efficacy short form

A 3-items scale for the measurement of self-efficacy [4].
