Primary Orthostatic Tremor



  • It is remarkable that the characteristic activation and deactivation pattern in orthostatic tremor is already present in the supine position without tremor presentation.[ncbi.nlm.nih.gov]
  • Although rare, some PD cases can also present with leg tremors on standing. Those tremors have distinctive frequency bands, 13-18 Hz for OT and 4-9 Hz for PD, determined by SEMG.[mdsabstracts.org]
  • Clinical Case 1 The patient was a healthy, 65-year old woman, who attended consultation due to instability, sensation of nausea and general malaise, along with heaviness of the lower limbs when standing, which was relieved by leg movement.[elsevier.es]

  • Falls were common, with one patient experiencing a fall with upper limb fracture whilst on the placebo. The frequency of falls correlated with both the severity of the self-rated symptoms and a shorter time to feeling unsteady with eyes closed.[ncbi.nlm.nih.gov]
  • Essential tremor and orthostatic tremor do not respond to the same therapies, suggesting differences in the pharmacological profiles of the two conditions.[ncbi.nlm.nih.gov]
  • Essential tremor and orthostatic tremor do not respond to the same therapies, suggesting differences in the pharmacological profiles of the two conditions.[ncbi.nlm.nih.gov]


  • Diagnostic workup in an older person with tremor Relevant history taking As with other clinical presentations, relevant and thorough history taking is essential in the diagnostic workup of tremor.[gmjournal.co.uk]
  • A laboratory workup is not necessary for most tremor patients.[clevelandclinicmeded.com]
  • (See Workup.) An association between essential tremor and dystonia has also been suggested. Some patients with focal dystonia, such as torticollis, have mild, bilateral upper extremity postural tremors.[emedicine.medscape.com]
  • Haloperidol Hypoglycemic agents Lithium Metoclopramide (Reglan) Methylphenidate (Ritalin) Pseudoephedrine Terbutaline Theophylline Thyroid hormones Tricyclic antidepressants Valproic acid (Depakene) Verapamil Metabolic causes of tremor are varied. 8 Initial workup[aafp.org]


  • Previous studies have reported a reduction in OT symptoms with gabapentin treatment. In this study, we report on the benefits of gabapentin treatment in a double-blind placebo-controlled crossover study of 6 OT patients.[ncbi.nlm.nih.gov]
  • Treatment According to Pradalier and associates(2002), clonzepam is the preferred treatment for orthostatic tremor. This is also the medication recommended by Glass and associates for orthostatic myoclonus.[dizziness-and-balance.com]

  • Thus, we cautiously propose that unilateral SLT as an initial symptom of PD might be a predictor of good prognosis for parkinsonism. However, this assumption should require further experiences to be confirmed. Figure 1.[e-jmd.org]

  • However, establishing the underlying cause is important because prognosis and specific treatment plans vary considerably. History and physical examination can provide a great deal of certainty in diagnosis.[aafp.org]


  • Chapters include sections on clinical phenomenology, etiology and pathogenesis and therapy. There are also on-line resources for clinicians and patients to refer to as well.[books.google.de]
  • Etiology At present, the pathophysiology of POT is unknown.[orpha.net]
  • These factors all suggest that OT and ET have separate etiologies. PET with H 2 15 O is a minimally invasive technique that can be used to measure regional cerebral bloodflow (rCBF) repeatedly in subjects while they perform different tasks.[neurology.org]

  • Medications, hyperthyroidism, ethanol, or dystonia are not potential etiologic factors. No psychogenic features (e.g., bizarre features, inconsistent in character, patient is distractable, other psychiatric features on examination).[online.epocrates.com]


  • Summary Epidemiology The prevalence is unknown. To date, around 390 cases have been reported in the literature. Women are predominantly affected (sex ratio: 2:1) with disease onset occurring in middle aged or elderly people.[orpha.net]
  • . • Sparse clinical findings, mostly limited to a fine rippling of the leg muscles that may be easier to feel than see.⁴ Epidemiology The incidence and prevalence of OT is unknown.² However, OT is generally considered a rare disorder that is under-recognised[pulsetoday.co.uk]

  • TREMORS PREVENTION Tremor prevention is as simple as avoiding what triggers their occurrence. Patients are advised to stay away from caffeine and other similar stimulants, including minimizing their alcohol consumption.[medicalook.com]
  • No preventive or neuroprotective therapy is available. Mild rest tremor without disabling motor symptoms does not require treatment.[clevelandclinicmeded.com]
  • This problem became progressively more severe and he found that he was having to lean on objects while standing to prevent himself falling. He did not describe propulsion or retropulsion.[jnnp.bmj.com]
