=====Strength of Individual Muscle Groups===== Patterns of weakness can help localize a lesion to a particular cortical or white matter region, spinal cord level, nerve root, peripheral nerve, or muscle. Test the strength of each muscle group and record it in a systematic fashion. It is wise to pair the testing of each muscle group immediately with testing of its contralateral counterpart to enhance detection of any asymmetries. see [[Medical Research Council Scale for Muscle Strength]]
