Dynamic electromyography (EMG) of the extrinsic muscles of the ankle is used more and more frequently to assist in the planning of tendon transfers in children with equinovarus deformities. Since these children walk at low speeds (1 to 4km/h), and since walking speed modifies the EMG-time pattern, the clinical investigator must be able to differentiate EMG(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)
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)
Body centre of gravity (CG) mechanics and electromyographic activity of flexor-extensor antagonistic muscles of the lower limb were simultaneously recorded in lowest and middle-level gait disorders. Muscle co-contractions between tibialis anterior and triceps surae, and between rectus femoris and hamstrings were evaluated. CG mechanics was assessed by the(More)
Human walking has a peculiar straight-legged style. Consequently, the body's centre of mass (CM) moves up and down with each step, which is noticeable in their up and down head bobbing while walking. This vertical CM movement enables humans to save energy via a pendulum-like mechanism but is probably a relatively recent locomotor innovation insofar as(More)
BACKGROUND Hemiparetic gait following stroke requires substantial energy consumption, which would promote deconditioning and disability. Optimal modalities for decreasing this energy cost remain challenging. Excessive energy consumption, however, seems to be mainly due to extra positive muscle work to substantially lift the body's center of mass (CM)(More)
Abnormal movements of the body segments due to lowest level gait disorders such as musculoskeletal disorders, peripheral neuropathies and radiculopathies or middle-level disorders such as hemiplegia, paraplegia and dystonia influence the motion of the centre of gravity (CG) during walking. The translation of the CG can be studied by the work done by muscles(More)
Adolescent idiopathic scoliosis (AIS) is a progressive growth disease that affects spinal anatomy, mobility, and left-right trunk symmetry. Consequently, AIS can modify human locomotion. Very few studies have investigated a simple activity like walking in a cohort of well-defined untreated patients with scoliosis. The first goal of this study is to evaluate(More)
This preliminary study presents the development and testing of an instrumented treadmill device measuring the ground reaction forces (GRFs) and the feasibility of using this force measuring treadmill (FMT) in clinical gait analysis. A commercially available treadmill was modified and fitted out with three-dimensional strain-gauge force transducers. Tests of(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)
