Akathisia (IPA: /æ.kə.ˈθɪ.si.ə/) is a movement disorder [5] characterized by a subjective feeling of inner restlessness accompanied by mental distress and/or an inability to sit still. [ 6 ] [ 4 ] Usually, the legs are most prominently affected. [ 2 ]
Hyperkinetic movement disorders refer to dyskinesia, or excessive, often repetitive, involuntary movements that intrude upon the normal flow of motor activity. Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity ...
Dysdiadochokinesia is demonstrated clinically by asking the patient to tap the palm of one hand with the fingers of the other, then rapidly turn over the fingers and tap the palm with the back of them, repeatedly. This movement is known as a pronation/supination test of the upper extremity. A simpler method using this same concept is to ask the ...
Since it is difficult to measure extrapyramidal symptoms, rating scales are commonly used to assess the severity of movement disorders. The Simpson-Angus Scale (SAS), Barnes Akathisia Rating Scale (BARS), Abnormal Involuntary Movement Scale (AIMS), and Extrapyramidal Symptom Rating Scale (ESRS) are rating scales frequently used for such assessment and are not weighted for diagnostic purposes ...
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [1] [2] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [3]
Symptoms of motor neuron diseases can be first seen at birth or can come on slowly later in life. Most of these diseases worsen over time; while some, such as ALS, shorten one's life expectancy, others do not. [2] Currently, there are no approved treatments for the majority of motor neuron disorders, and care is mostly symptomatic. [2]
Motor disorders are malfunctions of the nervous system that cause involuntary or uncontrollable movements or actions of the body. [3] These disorders can cause lack of intended movement or an excess of involuntary movement. [4] Symptoms of motor disorders include tremors, jerks, twitches, spasms, contractions, or gait problems.

Multiple system atrophy (MSA) is a rare neurodegenerative disorder [1] characterized by tremors, slow movement, muscle rigidity, postural instability (collectively known as parkinsonism), autonomic dysfunction and ataxia.
