Differentiating Motor Coordination and Position Sense in Children with Cerebral Palsy and Typically Developing
Insights
Robotic assessments can identify motor deficits in children with cerebral palsy (CP). Preliminary models using a reaching task showed impairments in one child, highlighting potential for targeted CP therapy.
Area of Science:
- Pediatric neurology
- Rehabilitation robotics
- Motor control research
Background:
- Childhood motor function and coordination naturally improve with age.
- Robotic assessments offer repeatable, objective, and accurate measures of motor skills.
- Previous studies utilized robotic assessments to quantify motor deficits in children with cerebral palsy (CP).
Purpose of the Study:
- To present preliminary results of using a normative model to identify motor function and coordination deficits in children.
- To evaluate the efficacy of age, sex, and handedness-adjusted normative models in detecting impairments.
- To assess the models' ability to identify motor deficits in children with CP using a robotic reaching task.
Main Methods:
- Development of normative models for motor function and coordination based on age, sex, and handedness.
- Assessment of motor function using a robotic reaching task in typically developing children and individuals with CP.
- Comparison of robotic assessment data from three participants with CP against the normative models.
Main Results:
- The normative models identified motor deficits in one participant with CP based on initial speed and distance ratios during a visually guided reaching task.
- No evidence of motor control deficits was found in the other two participants with CP using the current models.
- Preliminary findings suggest the models' potential in differentiating impaired from typical motor performance.
Conclusions:
- Normative models accounting for age, sex, and handedness show promise in identifying motor deficits in children with CP.
- Refinement of these models is necessary for improved identification and quantification of motor control impairments.
- Quantifiable goals derived from such models could potentially guide and target therapeutic interventions for CP.
Abstract:
Motor function and coordination improve as children age. Robotic assessments of motor function and coordination have been shown to be repeatable, objective, and accurate. Additionally, robotic assessments have been used to measure and quantify deficits in motor function and coordination in children with cerebral palsy (CP). Normative models of motor function and coordination based on age have not been used widely to differentiate impaired performance from typical performance. This study presents preliminary results of identifying deficits in motor function and coordination assessed with a robotic reaching task and using a normative model of typical performance that accounts for age, sex, and handedness. The models were compared with data from three participants with CP to evaluate whether the models could be used to identify deficits in motor function. The models indicated motor deficits in one participant when performing a visually guided reaching task with respect to initial speed and distance ratios. There was no evidence of motor control deficits in the other two participants. Future work will refine the models to be able to better identify and quantify motor control impairments with the potential to target therapy around quantifiable goals.
