Measure of early vision use: initial validation with parents of children with cerebral palsy

Effect of Hospital-Family Rehabilitation Intervention on Walking Function and Lower Limb Surface Electromyography in Children with Cerebral Palsy

Objective

To explore the effect of hospital-family rehabilitation intervention on walking function and lower limb surface electromyography in children with cerebral palsy (CP).

Methods

About 100 children with CP treated in our hospital from February 2019 to April 2021 were enrolled. The patients were randomly assigned into control group and study group. The control group received routine intervention, and the study group received hospital-family rehabilitation intervention. The intervention effect, GMFM88 scale score, IMMG value, CR value, lower limb surface EMG value, and compliance of gastrocnemius muscle and tibialis anterior muscle were compared.

Results

First of all, we compared the intervention effects. In the study group, 43 cases were markedly effective, 5 cases were effective, 1 case was improved, 1 case was ineffective, and the effective rate was 98.00%. In the control group, 22 cases were markedly effective, 14 cases were effective, 7 cases were improved, 7 cases were ineffective, and the effective rate of 86.00%. The intervention effect of the study group was better compared to the control group (P < 0.05). Secondly, we compared the scores of the GMFM88 scale. The scores of D area and E area and total score of the study group were higher compared to the control group (P < 0.05). The IEMG values of gastrocnemius muscle and tibialis anterior muscle were compared, and the IMMG values of passive and active gastrocnemius muscle and tibialis anterior muscle in the study group were higher compared to the control group (P < 0.05). There exhibited no significant difference in CR value before intervention (P > 0.05). After intervention, the CR values of gastrocnemius muscle and tibialis anterior muscle in the study group were significantly lower compared to the control group (P < 0.05). In terms of the surface EMG of lower limbs, the EMG value of passive activity (gastrocnemius muscle, tibialis anterior muscle) in the study group was higher compared to the control group, and the EMG value of active activity was significantly lower compared to the control group (P < 0.05). Finally, we compared the compliance. In the study group, there were 43 cases of complete compliance, 7 cases of compliance, and 0 cases of noncompliance, with a compliance rate of 100.00%. In the control group, there were 32 cases of complete compliance, 11 cases of compliance, and 7 cases of noncompliance with a compliance rate of 86.00%. The compliance rate of the study group was better compared to the control group (P < 0.05).

Conclusion

The intervention of hospital-family rehabilitation model is helpful to improve the self-care ability, cognitive function, and daily activities of children with CP, enhance the walking function and lower limb surface electromyography of children with SCP, and strengthen their qualities of life.

Measure of Early Vision Use: development of a new assessment tool for children with cerebral palsy

PURPOSE

To report the development of an assessment tool to describe "how vision is used" for children with cerebral palsy.

METHOD

Measurement development consisted of three steps: (i) an online survey to explore the relevance and comprehensiveness of visual behaviours identified in a previous conceptualisation study; (ii) construction of items and a rating scale for the new measure; and (iii) cognitive interviews to explore comprehensibility and refine the measure in preparation for field testing. Survey respondents were 130 parents of children with cerebral palsy, eight adults with cerebral palsy, and 108 clinicians (n = 246). Nine parents participated in the interviews.

RESULTS

The new tool, the Measure of Early Vision Use, is a 14-item descriptive measure of typical performance of visual behaviours observable in everyday activities, as rated by parent/caregiver observation. Each item is rated on a 4-point ordinal scale.

CONCLUSIONS

This new measure is conceptually grounded within the Activity level domain of the International Classification of Functioning, Disability and Health as a measure of a single visual ability construct. The target population is children with cerebral palsy, and using parent report the Measure of Early Vision Use describes both strengths and limitations in using vision. This study addressed the selection of items and response options for the new scale, and provides evidence to support content relevance, comprehensiveness and comprehensibility from key stakeholders. Further research will explore psychometric properties and clinical utility.Implications for rehabilitationThe ability to use vision in daily activities is relevant to the development and learning of all children, so the availability of a method for describing visual abilities has potential for diverse research and clinical purposes.The Measure of Early Vision Use is a parent-report tool that provides a criterion-referenced method for quantifying and describing how children use vision in typical daily activities to support intervention planning.Clinicians and parents wishing to measure vision use in children with cerebral palsy can be confident about the rigorous methods used to develop this tool, including consultation with key stakeholders.
