“…Recent studies in children with CP reported changes of the gait pattern towards more knee flexion during the early stance phase accompanied by signs of muscle fatigue after a 6-minute walking exercise (6MW) in children who walk in a crouched 8,9 or jump gait pattern. 10 This supports the idea that gait deviations progress with prolonged walking because of physical fatigue. Moreover, because minimization of ECoW is an important criterion for gait pattern optimization, 11 the results of these studies raise the question whether gait pattern changes that occur after prolonged walking would also result in a further increase in ECoW in children with CP.…”

AimTo obtain insights into the effects of fatigue on the kinematics, kinetics, and energy cost of walking (ECoW) in children with cerebral palsy (CP).MethodIn this prospective observational study, 12 children with CP (mean age 12 years 9 months, SD 2 years 7 months; four females, eight males) and 15 typically developing children (mean age 10 years 8 months, SD 2 years 4 months; seven females, eight males) followed a prolonged intensity‐based walking protocol on an instrumented treadmill, combined with gas analysis measurements. The protocol consisted of consecutive stages, including a 6‐minute walking exercise (6MW) at comfortable speed, 2 minutes of moderate‐intensity walking (MIW) (with a heart rate > 70% of its predicted maximal), and 4 minutes walking after MIW. If necessary, the speed and slope were incremented to reach MIW. Outcomes were evaluated at the beginning and end of the 6MW and after MIW.ResultsWith prolonged walking, Gait Profile Scores deteriorated slightly for both groups (p < 0.01). Knee flexion increased during early stance (p = 0.004) and ankle dorsiflexion increased during late stance (p = 0.034) in children with CP only. Negligible effects were found for kinetics. No demonstrable change in ECoW was found in either group (p = 0.195).InterpretationKinematic deviations in children with CP are progressive with prolonged walking. The large variation in adaptations indicates that an individual approach is recommended to investigate the effects of physical fatigue on gait in clinical practice.

“…CP is a clinical diagnosis based on symptoms and neurological signs, and a definite diagnosis is usually made between 12 and 24 months of age, but a review of the progress in early diagnosis and treatment of CP published in JAMA Pediatrics in 2017 combs the standardized tools for early prediction of CP and clearly proposes that the time of diagnosis can be advanced to before 6 months of gestational age [ 20 ]. Study reported that the incidence of CP is 1‰~5‰ in the world, 2‰~3‰ in developed countries, and 1.8‰~4‰ in China [ 21 ]. CP is the most common physical disability in children, with 2.1 cases per 1000 cases in high-income countries [ 22 ].…”

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.

In this paper, a gait classification method based on the deep belief network (DBN) optimized by the sparrow search algorithm (SSA) is proposed. The multiple features obtained based on surface electromyography (sEMG) are fused. These functions are used to train the model. First, the sample features, such as the time domain and frequency domain features of the denoised sEMG are extracted and then the fused features are obtained by feature combination. Second, the SSA is utilized to optimize the architecture of DBN and its weight parameters. Finally, the optimized DBN classifier is trained and used for gait recognition. The classification results are obtained by varying different factors and the recognition rate is compared with the previous classification algorithms. The results show that the recognition rate of SSA-DBN is higher than other classifiers, and the recognition accuracy is improved by about 2% compared with the unoptimized DBN. This indicates that for the application in gait recognition, SSA can optimize the network performance of DBN, thus improving the classification accuracy.
