Hand function and tactile perception in a sample of children with myelomeningocele
Insights
This study found that hand function and tactile perception in children with myelomeningocele (a type of spina bifida) are largely unrelated. However, both can be negatively impacted by hydrocephalus and high spinal cord lesions.
Area of Science:
- Pediatric Neurology
- Developmental Neuroscience
- Rehabilitation Medicine
Background:
- Myelomeningocele is a complex congenital condition affecting neurological development.
- Impaired hand function and tactile perception are common challenges in affected children.
- Understanding these sensory and motor deficits is crucial for effective intervention.
Purpose of the Study:
- To investigate the relationship between hand function and tactile perception in children with myelomeningocele.
- To explore the influence of spinal cord lesion level and hydrocephalus severity on these abilities.
- To identify potential correlations between sensory and motor deficits in this population.
Main Methods:
- Assessed hand function and tactile perception in 17 children diagnosed with myelomeningocele.
- Evaluated the correlation between various hand function measures and tactile perception tests.
- Analyzed the impact of lesion level and hydrocephalus status on performance.
Main Results:
- 14 children exhibited impaired hand function, while 8 showed tactile dysfunction.
- Significant differences in hand function and tactile scores were observed with increased hydrocephalus severity and higher spinal cord lesions.
- A statistically significant correlation was found in only one of the 48 computed coefficients between hand function and tactile perception measures.
Conclusions:
- Hand function and tactile perception appear to be independent factors in children with myelomeningocele.
- Severity of hydrocephalus and level of spinal cord lesion are associated with poorer outcomes in both domains.
- Clinical strategies should consider these distinct, yet potentially co-occurring, impairments.
Abstract:
The purpose of this investigation were to study the relationships between hand function abilities and tactile perception, and the level of spinal cord lesion and status of hydrocephalus in a sample of 17 children with myelomeningocele. Fourteen children showed impaired hand function, and eight showed tactile dysfunction. Statiscally significant differences in hand function scores and graphesthesia scores were obtained for children with increased severity of hydrocephalus and high-level lesions. Of the 48 correlation coefficients computed between the hand function and tactile perception measures used, only one was statistically significant. This lack of correlation may indicate that hand function and tactile perception in children with myelomeningocele are unrelated factors. Clinical implications of impaired hand function and tactile perception were discussed.
