Proposing a new short screening test for upper limb apraxia.

BACKGROUND

Apraxia has a major impact on activities of daily living in stroke patients. The proper assessment and treatment of apraxia is important for maintaining a good quality of life. We developed a short evaluation test for upper limb apraxia.

PATIENTS AND METHODS

The present Screening Test of Gestures for Stroke consists of 10 items for each verbal instruction and imitation. Each item includes three meaningless gestures, three meaningful gestures and four pantomimes. The Screening Test of Gestures for Stroke is scored based on a 3-point system: 10, 5 or 0 (maximum score: 200). The test took approximately 2-5 min to complete. We recruited 65 patients admitted to our hospital with left hemisphere stroke and 50 healthy subjects.

RESULTS

The reliability of the Screening Test of Gestures for Stroke was as follows: the intraclass correlation coefficient of intra-rater reliability was 0.93 for both verbal instructions and imitations, and the intraclass correlation coefficient total scores for inter-rater reliability for verbal instructions and for imitations were 0.97 and 0.95, respectively. The alpha coefficient was ≥0.80.

CONCLUSIONS

The Screening Test of Gestures for Stroke is a reliable and valid bedside test that has a short assessment time, does not require special equipment and can evaluate upper limb apraxia in stroke patients from the acute to the chronic phase.
