| Caused by midline damage to the cerebellar vermis | |
| Specialty | Neurology |
| Symptoms | "drunken sailor" gait characterised by uncertain starts and stops, falling |
| Causes | Spinocerebellar Ataxia (Lesion in Flocculonodular Lobe OR Vestibulo-cerebellum) |
Truncal ataxia (or trunk ataxia) is a wide-based "drunken sailor" gait characterised by uncertain starts and stops, lateral deviations and unequal steps. It is an instability of the trunk and often seen during sitting. [2] It is most visible when shifting position or walking heel-to-toe. [1]
As a result of this gait impairment, falling is a concern in patients with ataxia. [3]
Truncal ataxia affects the muscles closer to the body such as the trunk, shoulder girdle and hip girdle. It is involved in gait stability. [3]
Truncal ataxia is different from appendicular ataxia. Appendicular ataxia affects the movements of the arms and legs. It is caused by lesions of the cerebellar hemispheres. [3]
Causes
Truncal ataxia is caused by midline damage to the cerebellar vermis. There are at least 34 conditions that cause truncal ataxia. [2]
Common
- Alcohol intoxication [1]
- Cerebellar infarction [1]
- Cerebellar hemorrhage [1]
- Cerebellar ataxia [1]
- Multiple sclerosis [1]
- Friedreich's ataxia [1]
- Drugs such as Benzodiazepines, Lithium, Phenytoin [1]
Uncommon
- Adrenoleukodystrophy [4]
- Ataxia oculomotor apraxia type 1 [4]
- Branchial myoclonus [4]
- Christianson syndrome [4]
- Dandy–Walker syndrome [4]
- Dysequilibrium syndrome [4]
- Epilepsy [4]
- Episodic ataxia [4]
- Post viral cerebellar ataxia [1]
- Gerstmann–Sträussler–Scheinker syndrome [4]
- Machado–Joseph disease [4]
- Microcephaly [4]
- N-acetylaspartate deficiency [4]
- Neuhauser–Eichner–Opitz syndrome [4]
- Paraneoplastic cerebellar degeneration [1]
- Polymicrogyria [4]
- Rett syndrome [4]
- Spinocerebellar ataxia [4]
- Vertebral dissection [1]
