Timing responses of children with spina bifida having varying ambulatory abilities
1University of Toledo, OH 43606-3390.
Insights
Children with spina bifida (SB) show varying upper extremity timing responses. Ambulatory children with SB performed better on reaction and movement tasks compared to those with limited ambulation, suggesting tailored educational approaches are beneficial.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatric Rehabilitation
Background:
- Spina bifida (SB) is a complex congenital condition affecting neural development and motor function.
- Understanding the perceptual-motor processing abilities in children with SB is crucial for targeted interventions.
- Ambulation level significantly impacts functional outcomes and cognitive-motor performance in children with SB.
Purpose of the Study:
- To investigate the timing responses (reaction and movement) of upper extremities in children with spina bifida across different ambulation levels.
- To compare the performance on simple and choice timing tasks between ambulatory, household-only ambulatory, and nonambulatory children with SB.
- To infer differences in perceptual-motor processing abilities based on ambulation status in this population.
Main Methods:
- A cohort of 24 children with spina bifida, categorized by ambulation level (ambulatory, household-only ambulatory, nonambulatory), participated.
- Subjects completed four timing tasks using a Lafayette reaction and movement timer: simple reaction time, choice reaction time, simple movement time, and choice movement time.
- A 2 x 3 x 4 repeated measures analysis of variance was employed to analyze the timing data.
Main Results:
- Children with spina bifida who were ambulatory demonstrated significantly faster and more accurate performance across all four timing tasks compared to household-only ambulatory and nonambulatory groups.
- The household-only ambulatory group also exhibited superior performance in speed and accuracy over the nonambulatory group for the timing tasks.
- These findings indicate distinct perceptual-motor processing capabilities correlating with the degree of ambulation in children with SB.
Conclusions:
- Ambulation level is a significant factor influencing upper extremity timing responses and perceptual-motor abilities in children with spina bifida.
- The study infers varying levels of perceptual-motor processing efficiency among children with SB based on their ability to ambulate.
- An individualized educational strategy tailored to specific ambulation levels is recommended to enhance psychomotor skills in children with spina bifida.
Abstract:
The authors investigated the timing responses of upper extremities to light and sound stimuli of 24 ambulatory, household-only ambulatory, and nonambulatory children with spina bifida. Using a Lafayette reaction and movement timer, each subject performed four timing tasks: (a) simple reaction time, (b) choice reaction time, (c) simple movement time, and (d) choice movement time. A 2 x 3 x 4 analysis of variance with repeated measures indicated that the ambulatory spina bifida children performed all timing tasks faster and more accurately than the household-only ambulatory and nonambulatory children. In addition, the household-only ambulatory group performed the timing tasks faster and more accurately than the nonambulatory group. Therefore, different perceptual-motor processing abilities are inferred for children with spina bifida who ambulate with different ability. For maximum benefit, an individualized educational approach should be used to improve psychomotor abilities of spina bifida children who have differing levels of ambulation.
