Motor training targeted to goals that are relevant to the functional needs of the patient

Each item is rated on a three-point ordinal scale (2 points for the detail being performed completely, 1 point for the detail being performed partially, and 0 for the detail not being performed). The maximum motor performance score is 66 points for the upper extremity.

Muscle tone is defined by the resistance of a muscle being stretched without resistance. The MAS scores were distributed across the entire scale, ranging from 0 to 4, that is convenient for the clinician use. The grading of the scale is described as below: 0) no increase in muscle tone; 1) minimal resistance at the end of the range of motion; 1+) slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the reminder (less than half) of the ROM; 2) more marked increase in tone but only after part is easily flexed; 3) considerable increase in tone; and 4) passive movement is difficult and affected part is rigid in flexion or extension.
