In vascular hemiplegia, motricity of the upper and lower limbs can be assessed from the examination of a limited number of movements which have been selected by a statistical procedure. For these movements the scores may be weighted on the basis of progress achieved over 2, 4 and 6 months. From the weighted, summed and averaged scores, a motricity index may be derived. This index gives a rapid overall indication of a patient's progress in motor recovery, permits comparisons between different patients and the establishment of correlations with other clinical data and the values obtained by paraclinical techniques.
