Table 1. Important aspects of the clinical history in patients with gait disturbances.

Duration and course	Episodic (e.g., related to blood pressure) or continuous (e.g., polyneuropathy) Sudden onset (e.g., stroke) or slow progression (e.g., spinocerebellar ataxia)
Precipitating and exacerbating factors	Environment (e.g., darkness, uneven ground in bilateral vestibulopathy) Situation (e.g., phobia) Dual-tasking (e.g., talking while walking) Medication use
Accompanying symptoms and signs	Dizziness (e.g., cerebellar ataxia) Anxiety (e.g., fear of falling) Pain (e.g., arthritis) Sensory deficit (e.g., polyneuropathy)
Medications and alcohol	Benzodiazepines, barbiturates, antidepressants, neuroleptic drugs, antiepileptic drugs, medications to treat parkinsonism, analgesics, Antihypertensive drugs, antiarrhythmic drugs, antidiabetic drugs Alcohol consumption
Comorbidities	Cardiac/pulmonary (e.g., heart failure with decreased reserve) Metabolic syndrome (e.g., diabetes with polyneuropathy)
Falls	Single (e.g., with fear of falling afterward) Recurrent (e.g., progressive supranuclear palsy) Mechanism (e.g., stumbling, loss of muscle tone, syncope)
