Popis: Summary (Table I) I. The factors concerned in maintainingnormal muscle tone have been described in detail as a background to the understanding of the possible sites of pathology which can lead to hypotonia. II. The causes of hypotonia in childrenunder 24 months of age have been discussed from the point of view of the presumed site of pathology. The classification which has evolved from this approach is as follows: A. Hypotonia due to diseases of thecentral nervous system: 1. Atonic diplegia 2. Congenital chorea and athetosis 3. Congenital cerebellar ataxia 4. Kernicterus 5. Mongolism 6. Tay-Sach's diseas B. Hypotonia due to diseases of thespinal cord: 1. Werdnig-Hoffman's disease (infantileprogressive muscular atrophy) 2. Myelopathic arthrogryposis multiplexcongenita 3. Congenital anterior poliomyelitis C. Hypotonia due to diseases of thespinal roots or peripheral nerves: 1. Acute and chronic polyneuropathy D. Hypotonia due to abnormalities of the myoneural junction: 1. Congenital myasthenia gravis 2. Neonatal (transient) myasthenia gravis E. Hypotonia due to diseases of themuscle: 1. Benign congenital hypotonia 2. Universal muscular hypoplasia 3. Congenital infantile muscular dystrophy with or without arthrogryposis multiplex congenita 4. Dystrophica myotonica 5. Central core disease 6. Rod body myopathy 7. Polymyositis 8. Glycogen storage disease III. The value of ancillary aids in thediagnosis of the etiology of hypotonia in infants has been discussed. These have included muscle biopsy, electromyography, measurement of the nerve conduction time, determination of serum enzyme concentrations, urinary creatine and creatinine excretion coefficients, and the assessment of the developmental level of the infant.
