Autonomous nervous system regulation of pain in children with cerebral palsy

A concept for emotion recognition systems for children with profound intellectual and multiple disabilities based on artificial intelligence using physiological and motion signals

PURPOSE

This study proposes a concept for emotion recognition systems for children with profound intellectual and multiple disabilities (PIMD) based on artificial intelligence (AI) using physiological and motion signals.

METHODS

First, the heartbeat interval (R-R interval, RRI) of a child with PIMD was measured, and the correlation between the RRI and emotion was briefly tested in a preliminary experiment. Then, a concept based on AI for emotion recognition systems for children with PIMD was created using physiological and motion signals, and an emotion recognition system based on the proposed concept was developed using a random forest classifier taking as inputs the RRI, eye gaze, and other data acquired using low physical burden sensors. Subsequently, the developed emotion recognition system was evaluated, validating the proposed concept. Finally, we proposed a validated concept for emotion recognition systems.

RESULTS

A correlation was found between the RRI and emotion. The emotion recognition system was created based on the proposed concept and tested. According to the results, the recognition rate of "negative" and "not negative" of 70.4% ± 6.1% (Mean ± S.D.) of the developed emotion recognition system was higher than 48.5% ± 5.0% of an unfamiliar person used as a control.

CONCLUSION

The results indicate that the proposed concept for emotion recognition systems is useful for communicating with children with PIMD.

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.
