Measuring arm impairment and disability after stroke.

Abstract

This is a review of the problems of assessing impairments and disabilities affecting the arm after stroke, and of the various published measures already available. In routine clinical practice, motor impairment is best assessed using grip strength or the Motricity Index, and dexterity disability is best assessed using the Nine-Hole Peg Test or Ten-Hole Peg Test. No measures of sensation and tone are specifically recommended, primarily because validity and reliability has not been well established for the measures available. Other more complex tests appropriate for more detailed use in planning treatment or in research are discussed.
