BACKGROUND Poor control of reaching in spastic hemiparetic patients could be because of a combination of poor individuation of joints, weakness, spasticity, and/or sensory loss. OBJECTIVE To assess the effect of botulinum toxin injections (BTIs) on spasticity, upper-limb function, and kinematics of reaching movements in patients with spastic hemiparesis(More)
BACKGROUND Following stroke, patients frequently demonstrate loss of motor control and function and altered kinematic parameters of reaching movements. Feedback is an essential component of rehabilitation and auditory feedback of kinematic parameters may be a useful tool for rehabilitation of reaching movements at the impairment level. The aim of this study(More)
BACKGROUND The velocity of reaching movements is often reduced in patients with stroke-related hemiparesis; however, they are able to voluntarily increase paretic hand velocity. Previous studies have proposed that faster speed improves movement quality. OBJECTIVE To investigate the combined effects of reaching distance and speed instruction on trunk and(More)
Stiff knee gait (SKG) is common in hemiplegic patients. The main focus of treatment is rectus femoris (RF) spasticity. The aims of this study were to evaluate the effect of botulinum toxin injection (BTI) in the RF muscle on peak knee flexion during swing phase and its quantitative and functional impact on gait. We also wished to evaluate the correlation(More)
OBJECTIVE To investigate the mechanisms underlying the intermanual transfer of sensorimotor memory when lifting an object. METHODS Twenty healthy subjects grasped and lifted an object with constant mechanical properties with the right hand (RH) first and then with the left hand (LH). Ten of the subjects lifted the object with the RH in a regular wrist(More)
BACKGROUND Results of recent studies have suggested that restraint of non-paretic lower limb movement could improve locomotion in hemiplegic patients. The aim of this study was therefore to determine if a mass applied to the non-paretic lower limb during a single gait training session (GTS) would specifically improve spatio-temporal, kinematic and kinetic(More)
OBJECTIVE To assess by simulation the cost-effectiveness of intrathecal baclofen (ITB) therapy compared with conventional medical treatments for patients with disabling spasticity and functional dependence caused by any neurological disease. METHODS Two models were created to simulate therapeutic strategies for managing severe spasticity, one with and one(More)
BACKGROUND Poor control of grasping in spastic, hemiparetic patients could be because of a combination of poor individuation of joints, weakness, spasticity, and sensory loss. OBJECTIVE To investigate the effect of botulinum toxin injections (BTIs) on grasping objects of different shapes and to assess the effect on upper-limb function, reach-to-grasp(More)
In addition to changes in spatio-temporal and kinematic parameters, patients with stroke exhibit fear of falling as well as fatigability during gait. These changes could compromise interpretation of data from gait analysis. The aim of this study was to determine if the gait of hemiplegic patients changes significantly over successive gait trials. Forty two(More)
BACKGROUND AND PURPOSE wallerian degeneration (WD) in descending motor tracts after stroke is described at the level of the internal capsule and the brainstem. We investigated whether diffusion tensor imaging (DTI) can detect degeneration in the lateral cervical spinal cord after stroke. METHODS DTI at 1.5 T of the cervical spinal cord was performed in 4(More)
