The congenital mirror movements begin in infancy and persist throughout the patient's life, often with very little improvement, or deterioration. [3] Consequently, patients with this movement disorder have serious difficulty carrying out tasks that require manual dexterity or precision, such as playing a two handed musical instrument or typing ...
Ulnar dimelia, also referred to simply as mirror hand, is a very rare congenital disorder characterized by the absence of the radial ray, duplication of the ulna, duplication of the carpal, metacarpal, and phalanx bones, and symmetric polydactyly.
Movement disorders are clinical syndromes with either an excess of movement or a paucity of voluntary and involuntary movements, unrelated to weakness or spasticity. [1] Movement disorders present with extrapyramidal symptoms and are caused by basal ganglia disease . [ 2 ]
Facial synkinesis is a common sequela to Idiopathic Facial Nerve Paralysis, also called Bell's Palsy or Facial Palsy. [2] Bell's Palsy, which is thought to occur due to a viral reactivation which can lead (through unknown mechanisms) to diffuse axon demyelination and degeneration of the seventh cranial nerve, results in a hemifacial paralysis due to non-functionality of the nerve.
Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place.
Congenital myopathy is a very broad term for any muscle disorder present at birth. This defect primarily affects skeletal muscle fibres and causes muscular weakness and/or hypotonia. Congenital myopathies account for one of the top neuromuscular disorders in the world today, comprising approximately 6 in 100,000 live births every year. [1]
L1 syndrome is a group of mild to severe X-linked recessive disorders that share a common genetic basis. The spectrum of L1 syndrome disorders includes X-linked complicated corpus callosum dysgenesis, spastic paraplegia 1, MASA syndrome, and X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS).
Ramachandran created the mirror box to relieve pain by helping an amputee imagine motor control over a missing limb. Mirror therapy is now also widely used for treatment of motor disorders such as hemiplegia or cerebral palsy. As Deconick et al. state in a 2014 review, the mechanism of improved motor control and pain relief may differ from the ...
