Paratonia is the inability to relax muscles during muscle tone assessment. There are two types of paratonia: oppositional and facilitatory. Oppositional paratonia ("gegenhalten") occurs when subjects involuntarily resist passive movements, [1] while facilitatory paratonia ("mitgehen") occurs when subjects involuntarily assist with passive ...
Hypertonia is a term sometimes used synonymously with spasticity and rigidity in the literature surrounding damage to the central nervous system, namely upper motor neuron lesions. [1] Impaired ability of damaged motor neurons to regulate descending pathways gives rise to disordered spinal reflexes , increased excitability of muscle spindles ...
Hypokinesia is characterized by a partial or complete loss of muscle movement due to a disruption in the basal ganglia. [citation needed] Hypokinesia is a symptom of Parkinson's disease shown as muscle rigidity and an inability to produce movement. It is also associated with mental health disorders and prolonged inactivity due to illness ...
In psychology, rigidity, or mental rigidity, refers to an obstinate inability to yield or a refusal to appreciate another person's viewpoint or emotions and the tendency to perseverate, which is the inability to change habits and modify concepts and attitudes once developed. [1] [2]
Malignant hyperthermia and malignant catatonia share features of autonomic instability, hyperthermia, and rigidity. However, malignant hyperthermia is a hereditary disorder of skeletal muscle that makes these patients susceptible to exposure to halogenated anesthetics and/or depolarizing muscle relaxants like succinylcholine. [53]
This can result in increased muscle contractility, which can play a role in the breakdown of muscle, muscle rigidity, and hyperthermia. Some antipsychotic drugs, such as typical antipsychotics , are known to block dopamine receptors; other studies have shown that when drugs supplying dopamine are withdrawn, symptoms similar to NMS present ...
Stiff-person syndrome (SPS), also known as stiff-man syndrome, [1] is a rare neurological disorder of unclear cause characterized by progressive muscular rigidity and stiffness. The stiffness primarily affects the truncal muscles and is characterised by spasms , resulting in postural deformities.
Another muscle relaxant, baclofen, can help reduce spasticity seen in cerebral palsy such as dystonia in the leg and trunk. Treatment of secondary dystonia by administering levodopa in dopamine-responsive dystonia , copper chelation in Wilson's disease, or stopping the administration of drugs that may induce dystonia have been proven effective ...
