Hand function in children with myelomeningocele.
Hand function in 33 patients with myelomeningocele, aged from 4 to 17 years, was investigated by clinical examination and formal tests of co-ordination and dexterity. The average score for hand function was 59% of normal and only two children had clinically normal upper limbs. Twenty-eight patients (85%) had cerebellar ataxia, either alone or combined with other abnormal signs, most commonly upper motor neuron lesions. Hand function was significantly better in children of 11 years and older, in children under 11 with milder degrees of hydrocephalus, and in the younger children who were right-handed. Function was not shown to be better in those with lesions lower in the spine, nor in those with stable spines as has been previously reported. When co-ordination of the upper limb, manual dexterity and simultaneous movements of both arms were examined separately, these three were affected equally. Some abnormalities of hand function could be overcome by encouraging affected children to sit up and to practise skillful use of their hands as early in life as possible.
