Clinical assessment of upper limb hypertonia in central neurological diseases.

Abstract The clinical assessment of a hypertonic upper limb in central neurological diseases should be analytical, systematic (shoulder, elbow, extrinsic and intrinsic hand) and focused on the patient or caregiver’s wishes and on the expected objectives (esthetic, hygienic, functional). Nerve blocks can help to separate mixed contractures, show the existence of antagonist muscles or find a starter muscle in dystonia patterns. The etiology (especially the evolving nature of the disease), general health condition (especially in older adults), associated deficits (cerebellar, sensory and cognitive; hemineglect) are considered together to arrive at a contract with patients and/or caregivers.
