The relationship between parkinsonian rigidity and hypokinesia in the orofacial system: a quantitative analysis. 1982

C J Hunker, and J H Abbs, and S M Barlow

Muscle rigidity was quantified in the labial muscles of parkinsonian and normal subjects by applying known forces and observing the resultant displacements to determine labial stiffness coefficients. In parallel, labial speech movements were observed from these same subjects to evaluate hypokinesia. Labial rigidity was consistently correlated with decrements in the range of lip movement. EMG from orbicularis oris and mentalis muscles indicated a causal relationship between rigidity and hypokinesia.

D009069	Movement Disorders	Syndromes which feature DYSKINESIAS as a cardinal manifestation of the disease process. Included in this category are degenerative, hereditary, post-infectious, medication-induced, post-inflammatory, and post-traumatic conditions.	Dyskinesia Syndromes,Etat Marbre,Status Marmoratus,Movement Disorder Syndromes,Dyskinesia Syndrome,Movement Disorder,Movement Disorder Syndrome
D009127	Muscle Rigidity	Continuous involuntary sustained muscle contraction which is often a manifestation of BASAL GANGLIA DISEASES. When an affected muscle is passively stretched, the degree of resistance remains constant regardless of the rate at which the muscle is stretched. This feature helps to distinguish rigidity from MUSCLE SPASTICITY.

D010300	Parkinson Disease	A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.
