The energy cost of walking (C) in nine chronic hemiparetic patients was calculated by measuring the total mechanical work (Wtot) done by the muscles and the efficiency of this work production (eta). The energy cost was twice normal in slow walkers and 1.3 times greater in fast walkers. The increase in C was proportional to the increase in Wtot and eta was(More)
INTRODUCTION Botulinum toxin type A (BoNT-A) injections are known to improve walking impairments and activity in spastic hemiparetic stroke patients presenting with a stiff-knee gait [Caty GD, Detrembleur C, Bleyenheuft C, Deltombe T, Lejeune TM. Effect of simultaneous botulinum toxin injections into several muscles on impairment, activity, participation,(More)
BACKGROUND Several pilot studies have evoked interest in robot-assisted therapy (RAT) in children with cerebral palsy (CP). OBJECTIVE To assess the effectiveness of RAT in children with CP through a single-blind randomized controlled trial. PATIENTS AND METHODS Sixteen children with CP were randomized into 2 groups. Eight children performed 5(More)
OBJECTIVE Evaluation of normal and pathological gait on the level ground has drawbacks that could be overcome by walking on a treadmill. The present work was designed to assess the feasibility of extended gait analysis on a treadmill allowing multiple steps recording at a constant speed in young healthy subjects. It also aimed to provide speed-specific(More)
OBJECTIVE To validate a protocol assessing upper limb kinematics using a planar robot among stroke patients. DESIGN Prospective cohort study. SUBJECTS Age-matched healthy subjects (n = 25) and stroke patients (n = 25). METHODS Various kinematic indices (n = 44) were obtained from 4 tasks performed by subjects with REAplan, a planar end-effector(More)
OBJECTIVE To compare kinematic indices in age-matched healthy subjects and stroke patients, by evaluating various tasks performed with a robotic device, and to provide an objective and standardized protocol to assess upper limb impairments in stroke patients. DESIGN A prospective cohort study. SUBJECTS Age-matched healthy subjects (n = 10) and stroke(More)
BACKGROUND The energy consumed per covered distance (C) is increased in hemiparetic stroke adults during walking. OBJECTIVE To ascertain if increased C in stroke patients is a result of increased mechanical work, of decreased efficiency of work production by muscles or of slow walking speed. METHODS C and mechanical work were computed in 20 patients(More)
BACKGROUND Selective neurotomy is a permanent treatment of focal spasticity, and its effectiveness in treating spastic equinovarus of the foot (SEF) was previously suggested by a few nonrandomized and uncontrolled case-series studies. OBJECTIVES This study is the first assessor-blinded, randomized, controlled trial evaluating the effects of this(More)
OBJECTIVE To develop a questionnaire (ABILOCO), based on the Rasch measurement model, that can assess locomotion ability in adult stroke patients (International Classification of Functioning, Disability and Health activity domain). DESIGN Prospective study and questionnaire development. SETTING A faculty hospital. PARTICIPANTS Adult stroke patients(More)
OBJECTIVE To study the effect of botulinum toxin type A (BTX-A) injection in the rectus femoris on the decreased knee flexion during the swing phase of gait (stiff-knee gait) in people with stroke. DESIGN Intervention study (before-after trial) with an observational design. SETTING Outpatient rehabilitation clinic and gait laboratory. PARTICIPANTS(More)
