Exploring Kinetic and Kinematic Finger Individuation Capability in Children With Hemiplegic Cerebral Palsy

McCall, J. V., Hu, X., & Kamper, D. G. (2022, December 13). PERCEPTUAL AND MOTOR SKILLS.

By: J. McCall n, X. Hu * & D. Kamper n

author keywords: physical development & measurement; development testing; child motor development; medical disorders
MeSH headings : Humans; Child; Adolescent; Biomechanical Phenomena; Cerebral Palsy; Hemiplegia; Individuation; Fingers
TL;DR: This small sample of children with hCP showed substantial loss of individuation in the paretic hand and some deficits in the non-paretic hands, suggesting possible benefit from targeted training of digit independence in both hands for children with CP. (via Semantic Scholar)

2021 review

Hand function development of children with hemiplegic cerebral palsy: A scoping review

[Review of ]. JOURNAL OF PEDIATRIC REHABILITATION MEDICINE, 15(1), 211–228.

By: J. McCall n, M. Ludovice n, C. Elliott * & D. Kamper n

author keywords: Hand function; assessment methods; hemiplegia; cerebral palsy; upper limb
MeSH headings : Biomechanical Phenomena; Cerebral Palsy; Child; Hand; Hemiplegia / etiology; Humans; Physical Therapy Modalities; Upper Extremity
TL;DR: While several studies have evaluated hand function in children with hCP, the majority relied on clinical scales, assessments, or qualitative descriptions and further assessments of kinematics, kinetics, and muscle activation patterns are needed to identify the underlying impairment mechanisms that should be targeted for treatment.

2021 article

High Compliance Pneumatic Actuators to Promote Finger Extension in Stroke Survivors

2021 43RD ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE & BIOLOGY SOCIETY (EMBC), pp. 4588–4591.

By: J. McCall n & D. Kamper n

MeSH headings : Fingers; Hand; Humans; Robotics; Stroke / therapy; Survivors
TL;DR: A characterization of the extension force and passive flexion resistance generated by these pneumatic chambers across a range of joint angles as a function of cross-sectional shape, dimension, and wall thickness provides guidance in designing pNEumatic actuators for assisting finger extension and resisting unwanted flexion in the fingers.

2021 journal article

Neuromechanics and Energetics of Walking With an Ankle Exoskeleton Using Neuromuscular-Model Based Control: A Parameter Study

FRONTIERS IN BIOENGINEERING AND BIOTECHNOLOGY, 9.

By: B. Shafer *, S. Philius n, R. Nuckols *, J. McCall n, A. Young * & G. Sawicki*

author keywords: powered ankle exoskeleton; neuromuscular model; locomotion neuromechanics; human walking; muscle electromyography; metabolic energy cost; plantarflexor muscle-tendon mechanics
TL;DR: An ankle exoskeleton controller is developed that uses a neuromuscular model (NMM) comprised of a Hill type musculotendon driven by a simple positive force feedback reflex loop to capture the adaptive behavior of the human plantarflexors during natural gait. (via Semantic Scholar)
