Movement disorders are common conditions. The clinical presentation of movement disorders is complex and often has variation from person to person. Therefore, finding the correct diagnosis may be challenging. A focused physical examination and history are imperative, and many times the only required resource to establish the diagnosis. Movement disorders may be divided into hyperkinetic and hypokinetic, and this can be evaluated by performing a finger or foot tapping. Among the hyperkinetic disorders, you may classify them as jerky and non-jerky, while hypokinetic may vary in velocity, but in the end, are classified as a whole. The most common hyperkinetic disorder is essential tremor, while the most common hypokinetic one is Parkinson's disease.
Life Threatening Causes
Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.
|Patient with movement disorders|
|Perform physical examination|
|Perform finger or foot tapping|
|Increased alternating movements||Progressive fatiguing and decrement of repetitive alternating movements|
|Sudden, brief, shock-like involuntary movements||Randomly flowing movements, which are, individually, jerky in nature||‘Stereotyped’ character of the recurrent movements||Involuntary, rhythmic and sinusoidal alternating movements of one or more body parts||Involuntary abnormal co-contraction of antagonistic muscles, which may cause sustained abnormal postures or twisting and repetitive movements||Parkinsonism|

Management of movement disorders will vary depending on the underlying cause, among the treatment strategies, there is physical therapy, medical therapy, botulin toxin injection, and deep brain stimulation.

- Perform a physical examination with finger or foot tapping.
- Always ask for exacerbating and relieving factors; for example, involuntary movements that present in frequent, brief attacks that are induced by sudden movements (such as rising from a chair) suggest the diagnosis of paroxysmal kinesigenic dyskinesia.
- Inquire about ethnicity and family history of movement disorders as these aspects may guide into the diagnosis.
- Ask the patient's partner for the nature, pattern, and description of the movement disorder, since many times, these movements are hampered by the fact that patients frequently try to mask their abnormal movements by incorporating them into voluntary movements.
- Perform a systematic approach when encountering a patient with more than one type of movement disorder (mixed).
- Perform a urine toxicology test to look for drug-induced movement disorders such as tardive dystonia, postural tremor, parkinsonism, etc.
- Have in mind the possibility of adverse drug effects medication whenever patients present with a mixed movement disorder; the most common are dopamine D2 receptor-blocking agents such as neuroleptics.
- Perform genetic testing as the initial diagnostic step in possible genetic diseases that require confirmation, such as Huntington's disease.
- Do not order imaging or laboratory tests to diagnose clinical disorders, such as Parkinson's disease and essential tremor.
- Do not apply deep brain stimulation therapy for Parkinson's disease if any of the following are present: cognitive disturbances (Mattis score ≥130), major comorbidities, major depression (Beck depression score II <25), or other psychiatric contraindications, or neurosurgical contraindications.
