BACKGROUND Physiological co-activation of antagonistic muscles during gait allows stability of loaded joints. Excessive co-activation restrains motion and increases energy expenditure. Co-activation is increased by gait speed and in the case of upper motor neuron lesions. This study aimed to assess the pathological component of co-activation in children(More)
'Tremor' is one of the clinical signs of cerebellar dysfunction. Its nature remains subject to debate, one hypothesis being that of a predominant role of peripheral afferences in its genesis. This study was designed to study whether load compensating tasks, evoking sudden stretch, and thus stimulation of peripheral afferences induced tremor in cerebellar(More)
The authors describe a case of arachnoiditis ossificans (AO) of the cauda equina. The lesion is a rare pathological entity usually confined to the thoracic and high lumbar regions that can cause progressive spinal cord and cauda equina compression, inducing severe neurological deterioration. The authors analyze the clinical symptoms, radiological features,(More)
We present the case of a 54 year-old man presenting with a right Brown-Séquard plus syndrome (BSPS) after a traumatic cervical spinal cord injury. After being operated on with selective tibial neurotomy and triceps surae lengthening because of a right spastic equinus foot, he developed a gait disorder at high speed. The patient complained about an(More)
Spinal cord injuries often result in irreversible loss of motor and somatosensory functions below the lesion level. Treatment is limited to physiotherapy aimed at compensating disability. We previously showed that re-establishment of tissue continuity can be achieved in animal models through nerve autografts implanted between the rostral spinal ventral horn(More)
AIM We propose an improved technique for implanting a sacral root stimulator associated with dorsal sacral rhizotomy ("Brindley's technique") in a single intra-sacral approach. METHOD This novel technique only requires a single sacral laminectomy, consisting in a sacral deafferentation at the level of the dural cul-de-sac, facilitated by the anatomical(More)
OBJECTIVE To address the roles and mechanisms of co-activation in two flexor/extensor pairs during elbow extension in children with cerebral palsy (CP). METHODS 13 Typically Developing (TD) and 13 children with unilateral spastic CP performed elbow extension/flexion at different speeds. Elbow angle and velocity were recorded using a 3D motion analysis(More)
AIMS The Brindley procedure, used since the 1980s, consists of implantation of a stimulator for sacral anterior root stimulation combined with a posterior sacral rhizotomy to enable micturition. Patients suitable for the procedure are patients with detrusor overactivity and a complete spinal cord lesion with intact sacral reflexes. S2 to S4 posterior sacral(More)
BACKGROUND The theoretical role of muscle coactivation is to stiffen joints. The aim of this study was to assess the relationship between muscle coactivation and joint excursions during gait in children with and without hemiplegic cerebral palsy. METHODS Twelve children with hemiplegic cerebral palsy and twelve typically developing children underwent gait(More)
BACKGROUND Urinary disorders account for 10% of deaths in patients with complete spinal cord injury. Sacral anterior root stimulation (SARS) may be a valuable therapeutic option to restore complete and voluntary micturition (CVM), but questions on its cost-effectiveness remain. OBJECTIVE To evaluate the cost-effectiveness of SARS to restore CVM in(More)
