Rhythmic, oscillatory, and high amplitude tremor
- An intention, rubral, cerebellar, or course tremor is defined as a rhythmic, oscillatory, and high amplitude tremor during a directed and purposeful motor movement, worsening before reaching the target. It is due to cerebellar dysfunction. It can affect precision in coordinated movements of speech muscles and limbs.

Jan 7, 2024 · January 7, 2024. Intention tremor presents unique challenges to those affected by it. This article explains what intention tremor is, its causes and symptoms, and offers practical advice on how to manage and cope with this condition.
Intention tremors worsen as people get closer to the targeted object. These tremors are relatively slow and wide (coarse). Intention tremors may result from damage to the cerebellum, the part of the brain responsible for balance and coordination. Common causes of intention tremor include.
Nov 30, 2022 · Other debilitating symptoms may accompany the tremor, impacting posture, balance, and motor coordination. An intention tremor can feel alarming, especially if it's your first experience. Intention tremors occur due to cerebellar dysfunction. It affects coordinated movements of the limbs or muscles.
In this post, we’ll discuss two possible causes of tremor symptoms: essential tremor and intention tremor. We’ll start with an explanation of both, then take a look at essential tremor vs. intention tremor by detailing their differences in cause, diagnosis, and treatment.
What Are Multiple Sclerosis Tremors Like? The experience of tremor varies from person to person. For many, it feels like a lack of control of their movements. Tremor can be pronounced or slight. For instance, some people experience minor tremor, which sometimes affects their handwriting.

Scope: This page provides information on the different causes of intention tremor 1. intention tremor or tremor during target-directed movement is present when tremor amplitude increases during visually guided movements towards a target at the termination of movement 2. the possibility of postion-specific tremor or postural tremor produced at the beginning and end of a movement should be excluded 3. maximum tremor amplitude is reached at target 4. intention tremor may be accompanied by postur...

1. may be intention or postural tremoror both 2. tremor frequency usually below 5Hz 3. other cerebellar signs may be present: 3.1. nystagmus 3.2. dysarthria 3.3. dysmetria 3.4. dysdiadochokinesia 3.5. Holmes-Stewart manoeuvre "underdamping" (have the patient rest an elbow on a table and try to flex that arm against the resistance of the examiner; when the resistance is suddenly withdrawn, the affected arm rebounds to the patient's chest, whereas the normal arm flexes only slightly, the flexio...
Quick info:
1. essential tremor is a broadly symmetrical postural or kinetic tremor of the upper limbs 2. in some cases an intention tremor is also present 3. a positive family history in approximately 50% of cases 4. essential tremor is often alcohol responsive (in approximately 50% of cases) 5. It has a frequency range of 4-12Hz 6. It is usually progressive
Quick info:
1. typically there are three tremor components present (rest, postural and intention tremor) 2. symptoms often severe. -the action tremor severity is usually greater than that of the rest component 3. slow (frequency <4.5Hz) irregular tremor 4. tends to involve proximal (action tremor) and distal (rest tremor) muscles 5. Holmes tremor has numerous causes including stroke, vascular malformations, tumours, head injury, toxoplasmosis, major tranquilizers, radiation 6. typically 2 weeks to 2 year...

1. task specific or position specific They are not intention tremors, but are often considered to be by patients: 1.1. subtype of action tremor 1.2. occur almost specifically whilst performing a specific task (eg. writing) or maintaining a specific posture (eg. holding a pen). 1.3. can interfere with occupation 1.4. may respond to propranolol, primidone, anticholinergics or botulinum toxin but evidence is limited 2. The following are indications of a psychogenic tremor: 3. 3.1. sudden onset,...
Definition. Intention tremor is a type of involuntary, rhythmic, oscillatory movement that occurs during purposeful movements, such as reaching for an object or performing a specific task.
