A ciência de sistemas proporciona uma nova maneira de concetualizar a paralisia cerebral como uma condição complexa. Ela foi aplic...

要旨 現在、発達領域で推奨されているボバース臨床推論フレームワーク(Bobath Clinical Reasoning Framework: BCRF)によるボバース実践を、システム科学のレンズによって概念化し、小児期発症の障害に関連する様々な変数の相互関係・相関依存に対する全人的観点を提供する。BCRFはICFの各領域間の関係性を理解し、それぞれがどのように影響を与え、どのように影響を受けるのかを理解する助けとなる臨床推論の詳細なフレームワークである。BCRFは介入計画へとつながる観察に基づく学際的なシステムであり、実践的な推論のアプローチである。BCRFにより脳性麻痺(Cerebral Palsy: CP)などの障害における複雑な状況を全人的に理解し、神経学的障害がある人々の生涯にわたる...

Resumen La actual práctica de desarrollo Bobath recomendada dentro del Marco de Razonamiento Clínico Bobath (BCRF) puede conceptualizarse utilizando la visión de la ciencia de los sistemas. Proporciona, así, una perspectiva holística de la interrelación e interconexión de las variables asociadas con la discapacidad aparecida durante la infancia. El...

Objective: The aim was to explore the experiences of a group of Spanish physical therapists who apply the Bobath concept in the treatment of children with cerebral palsy, specifically to identify the components they experience as core and essential to the Bobath concept. Design: A qualitative phenomenological study. Methods: This study used purposi...

AimTo explore the appropriateness of using the interval-scale version of the Gross Motor Function Measure (GMFM-66) in paediatric acquired brain injury (ABI), and to characterize GMFM-66 recovery trajectories and factors that affect them.Method An observational study of gross motor recovery trajectories during rehabilitation at a single specialist...

Delivering and monitoring residential rehabilitation services for pupils with acquired brain injuries (ABI) is challenging because of variability in aetiology, age and pre-morbid characteristics. Therapists and educators in this residential rehabilitation setting identified the need for a comprehensive tool which would capture the pupils' ability t...

The majority of stroke patients experience upper limb motor impairment and reduced ability to perform basic activities. Shoulder strapping has been reported as a beneficial adjunct to rehabilitation therapies but has not been rigorously trialled. This study tested the feasibility of recruitment, intervention and outcome assessment protocols for fut...

Lack of complexity in general movements in early infancy is an important marker of potential motor disorders of neurological origin, such as cerebral palsy. Quantitative approaches to characterising this complexity are hampered by experimental difficulties in recording from infants in their first few months of life. The aim of this study was to des...

In adults, motoneurone pools of synergistic muscles that act around a common joint share a common presynaptic drive. Common drive can be revealed by both time domain and frequency domain analysis of EMG signals. Analysis in the frequency domain reveals significant coherence in the range 1-45 Hz, with maximal coherence in low (1-12 Hz) and high (16-...

X-linked Kallmann's (XKS) subjects, who display mirror movements, have abnormal corticospinal tracts which innervate motoneurons of the left and right distal muscles of the upper limb. The size of the abnormal ipsilateral projection is variable. We have used coherence and cumulant analysis between EEG and first dorsal interosseous muscle (1DI) EMG...

Human physiological tremor consists of mechanical-reflex and neurogenic components. The origin of the neurogenic component, classically detected in the frequency range 7-12 Hz, has been much debated. We have studied six subjects with X-linked Kallmann's syndrome (XKS) and mirror movements. In these subjects unilateral magnetic brain stimulation res...

The movement disorder of cerebral palsy (CP) is expressed in a variety of ways and to varying degrees in each individual. The condition has become more complex over the last 20 years with the increasing survival of children born at less than 28 to 30 weeks gestational age. Impairments present in children with CP as a direct result of the brain inju...

It has been shown that subjects maintain grasp stability by automatically regulating grip force in response to loads applied tangentially to a manipulandum held using a precision grip. Signals from cutaneous mechanoreceptors convey the information necessary for both the initiation and scaling of responses. The central neural pathways that support t...

Even the simplest movements require the co-contraction of many different muscles acting around different joints. Making a fist, for example, involves flexion at the interphalangeal and metacarpophalangeal joints, combined with extension at the wrist: co-contraction of the intrinsic hand muscles and forearm finger flexor muscles is combined with the...

The mechanism underlying mirrored activity/movements in normal individuals is unknown. To investigate this, we studied 11 adults and 39 children who performed sequential finger-thumb opposition or repetitive index finger abduction. Surface electromyographic (EMG) activity recorded from the left and right first dorsal interosseous muscles (1DI) duri...

The aim of this study was to examine the pathophysiological mechanisms underlying co-contraction in patients with dystonia (n = 6) and writer's cramp (n = 5). Multi-unit needle and surface EMGs were recorded from extensor carpi radialis (ECR) and flexor carpi radialis (FCR) muscles during motor tasks that elicited dystonia or writer's cramp. The EM...

Possible mechanisms underlying the pathological mirror movements that are seen in the majority of patients with X-linked Kallmann's syndrome have been investigated using neurophysiological techniques. An EMG was recorded from the first dorsal interosseous muscle (1DI) during voluntary self-paced abduction of one indexed finger; EMG activity could a...

To investigate the mechanism of mirror movements seen in X-linked Kallmann's syndrome, we measured changes of regional cerebral blood flow with H2 15O-PET. We studied six right-handed Kallmann male subjects and six matched, right-handed control subjects during an externally paced finger opposition task. The analyses were done both on a single subje...

Surface electromyography (EMG) and torque were measured from knee flexors and extensors in 12 control subjects (CS) aged 25-59 years (10 female) and bilaterally in 12 stroke subjects (SS) aged 27-75 years (four female) with hemiparesis and mild clinical spasticity. They performed isometric and isokinetic maximal voluntary contractions (MVC) and als...

One simple mechanism that could account for the co-contraction of synergistic muscles is that it is brought about by the sharing of common excitatory drive. To test this hypothesis we have performed cross-correlation analysis of motor unit discharges recorded during steady voluntary contractions in man (Bremner, Datta & Stephens, 1989; Bremner, Bak...
