Marche à petits pas [maʁʃ a pəti pa] (“gait with little steps”) is a type of gait disorder characterised by an abnormal short stepped gait with upright stance (in strict sense, as opposed to generally stooping short-stepped gait of Parkinson's disease), seen in various neurological (or sometimes muscular) disorders. It can be further differentiated from " Parkinsonian gait" by normal arm swing (as opposed to no arm swing in Parkinsonism). This is associated with frontal lobe white matter lesions. [1]
Common causes
Marche à petit pas gait is seen in:
- Bilateral diffuse cortical dysfunction
- Diffuse cerebrovascular disease ('lacunar state') [2]
- Normal pressure hydrocephalus [2]
- Multiple sclerosis
- Parkinsonism (sometimes)
- Muscle weakness
