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 ...
Rigidity is a severe state of hypertonia where muscle resistance occurs throughout the entire range of motion of the affected joint independent of velocity. It is frequently associated with lesions of the basal ganglia. Individuals with rigidity present with stiffness, decreased range of motion and loss of motor control.
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]
Paratonia is the inability to relax muscles during muscle tone assessment. There are two types of paratonia: oppositional and facilitatory. There are two types of paratonia: oppositional and facilitatory.
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.

The extent of the hyperkinesia exhibited in the disease can vary from solely the little finger to the entire body, resembling purposeful movements but occurring involuntarily. In children, rigidity and seizures are also symptoms. [11] Other hyperkinetic symptoms include: Head turning to shift eye position; Facial movements, including grimaces
Spasticity can be differentiated from rigidity with the help of simple clinical examination, as rigidity is a uniform increase in the tone of agonist and antagonist muscles which is not related to the velocity at which the movement is performed passively and remains the same throughout the range of movement while spasticity is a velocity ...
Dystonia, an abnormal muscle contraction; Pseudoparkinsonism, symptoms that are similar to what people with Parkinson's disease experience, including tremulousness and drooling; Hyperprolactinaemia (rare for those treated with clozapine, quetiapine and aripiprazole [18] [38]), which can cause: Galactorrhoea, the unusual secretion of breast milk.
