Patients with advanced Parkinson's disease may experience fluctuations between bradykinetic
(slowness of movement) and hyperdyskinetic (involuntary movement) states.
While commonalities exist between the obstacle-crossing behaviors displayed by subjects with PD and CTRL subjects, the crossing behavior demonstrated by the subjects with PD reflects bradykinetic
gait patterning that was not exacerbated by the presence of an obstacle.
Williams DR, Watt HC, Lees AJ, Predictors of falls and fractures in bradykinetic
rigid syndromes: a retrospective study, J Neurol Neurosurg Psychiatry.
1) HD is a progressive autosomal dominant disorder, characterised by involuntary choreiform movements, psychiatric manifestations with cognitive decline and, rarely, a bradykinetic rigidity.
The dementia was of a moderate to severe degree, and no patient had a picture of bradykinetic rigidity.
In NPH patients, the gait is commonly characterized as wide-based, short-stepped, shuffling, and bradykinetic
EPS are characterized as either hyperkinetic (excessive movements) or bradykinetic
Patients who presented with tremor were on average age 55 years at onset, compared with patients who presented with bradykinetic
rigidity (age 50 years at onset).
Characteristic features include resting tremor, rigidity, bradykinetic
(slow) movements and instability of posture.
Parkinsonism associated with HIV is described as symmetric and mostly bradykinetic
In addition, early signs of a movement disorder may be interpreted as tardive dyskinesia, or the patient may develop the bradykinetic
form of HD and , not show significant amounts of chorea.
