Mirror movements

Congenital mirror movements.

In this report are described seven patients assessed clinically and neuropsychologically in whom mirror movements affecting predominantly the hands occurred as a congenital disorder. These mirror movements, representing a specific type of abnormal synkinesia, may arise as a hereditary condition, in the presence of a recognisable underlying neurological abnormality, and sporadically, and the sev...

Mirror movements in neurology.

E xamination of patients for the presence or absence of mirror movements does not normally form part of a routine neurological investigation nor is this simple part of the motor examination normally taught to medical students and trainee neurologists. The examination requires the examiner only to observe both hands during voluntary fine finger movements of each hand in turn; for example, sequen...

Ataxic hemiparesis and mirror movements.

Quantitative assessment of mirror movements after stroke.

BACKGROUND AND PURPOSE Mirror movements (MM) are involuntary synchronous movements of one limb during voluntary unilateral movements of the opposite limb. We measured MM in stroke and control subjects and evaluated whether MM after stroke are related to motor function. METHODS Twenty-three patients and 16 control subjects were studied. A computerized dynamometer was used during two squeezing ...

Mirror Movements in Movement Disorders: A Review

BACKGROUND Mirror movements (MM) are involuntary movements of homologous muscles during voluntary movements of contralateral body regions. While subtle mirroring can be present in otherwise healthy adults, overt MM may be common in many movement disorders. Examining these collective findings may further our understanding of MM and help define their usefulness as a clinical sign. METHODS We so...
