Error Detection and Response Adjustment in Youth With Mild Spastic Cerebral Palsy
2013
This study evaluated the brain activation state during error making in youth with mild spastic cerebral palsy and a peer control group while carrying out a stimulus recognition task. The key question was whether patients were detecting their own errors and subsequently improving their performance in a future trial. Findings indicated that error responses of the group with cerebral palsy were associated with weak motor preparation, as indexed by the amplitude of the late contingent negative variation. However, patients were detecting their errors as indexed by the amplitude of the response-locked negativity and thus improved their performance in a future trial. Findings suggest that the con…
Visual Attention Study in Youth With Spastic Cerebral Palsy Using the Event-Related Potential Method
2011
Youth with mild spastic cerebral palsy (n = 14) and a peer control group were compared on an oddball paradigm. Here, visual stimuli were presented with low and high probability and participants were instructed to count in silence the number of rare stimuli. The infrequent stimulus typically elicits an enhanced frontal central N2 and a centroparietal P300 event-related brain potential, reflecting orientation and evaluation of stimulus novelty. No differences in latency and amplitude of the N2–P300 complex were found between the 2 groups, indicating that some fundamental attention processes are intact in youth with mild spastic cerebral palsy.
Deteriorated stabilization of walking in individuals with spastic cerebral palsy revealed by a simulated tripping perturbation
2014
Abstract. The aim of this study was to make use of a pr eviously introduced method of a simulated tripping perturbation to examine stability of walking in individuals with and with out cerebral palsy. This tripping perturbation is a forward-dynamics analys is, and it works so that in a subjec t-specific muscle-driven simulation of walking, created from experimental gait data, a force is applied to the swin g-foot, and resulting changes in the kinematics are observed. Here, changes in the fore-aft position of the trunk were analyzed. Subjects were 10 children with spastic diplegic cerebral palsy and eight un impaired children walking at their self-sel ected speed. Several tripping perturbati…
Medial gastrocnemius muscle and tendon interaction during gait in typically developing children and children with cerebral palsy
2020
1. IntroductionEfficient gait is dependent on optimal interaction between musclesand tendons [1]. Pathological changes in the extensibility of the MGmuscle fascicles, whole muscle-belly and Achilles tendon have beenreported in children with spastic cerebral palsy (CP) [2]. Studying therelative length of these tissues during gait can improve our understandingof their dynamics and, inferably, the control strategies used inCP. In-vivo dynamic ultrasound imaging has been used to visualise theinteraction between the MG muscle and tendon during 3D gait analysis.However, most studies combined ultrasound imaging of one variable(either fascicles or muscle-belly and tendon) with some form ofmusculosk…
Stimulus Evaluation, Event Preparation, and Motor Action Planning in Young Patients With Mild Spastic Cerebral Palsy: An Event-Related Brain Potentia…
2012
The study investigated stimulus evaluation time, event preparation, and motor action planning of patients with mild spastic cerebral palsy and a peer control group in the age range of 9 to 18 years. To this end, participants were carrying out a stimulus recognition task. Findings indicated an overall slowness and inaccurate reaction time performance of the patient group. An event-related potential analysis revealed that the stimulus evaluation processing, indexed by the parietal P300, was intact in the group of patients. Also event preparation and action planning, indexed by respectively the frontal late contingent negative variation and the frontal P2, were intact in the group of patients…
