BACKGROUND Botulinum toxin (BTX) injection into rectus femoris (RF) is a therapeutic modality used to improve knee flexion during the swing phase of gait in hemiparesis. The impact of this treatment on lower limb coordination is unknown. The authors evaluated whether BTX injection into RF is associated with modifications of intersegmental coordination in(More)
Adolescent idiopathic scoliosis is characterized by a three-dimensional deviation of the vertebral column and its etiopathogenesis is unknown. Various factors cause idiopathic scoliosis, and among these a prominent role has been attributed to the vestibular system. While the deficits in sensorimotor transformations have been documented in idiopathic(More)
PURPOSE To evaluate the consequences of placing an aortic stent over the renal arteries. MATERIALS AND METHODS The renal ostia of 11 pigs were covered by Strecker stents placed in the aorta. At 1 month, the degree of renal ostial stenosis was determined by means of angiography and gross pathologic and histologic examination. Any reduction in area of the(More)
OBJECTIVE Spastic co-contraction is a misdirected supraspinal command in spastic paresis. We quantified the influence of effort and gastrocnemius stretch on plantar flexor co-contraction and torque during dorsiflexion efforts in hemiparetic and healthy subjects. METHODS Eighteen healthy and 18 hemiparetic subjects produced "light", "medium" and "maximal"(More)
BACKGROUND/OBJECTIVE Gait training at fast speed has been suggested as an efficient rehabilitation method in hemiparesis. We investigated whether maximal speed walking might positively impact inter-segmental coordination in hemiparetic subjects. METHODS We measured thigh-shank and shank-foot coordination in the sagittal plane during gait at preferred (P)(More)
BACKGROUND The mechanisms altering knee flexion in hemiparetic gait may be neurological (muscle overactivity) or orthopedic (soft tissue contracture) in nature, a distinction which is difficult to ascertain clinically during gait. This study aimed to distinguish the 2 mechanisms in evaluating thigh-shank coordination, which may show instability across the(More)
BACKGROUND Botulinum toxin is commonly used to treat spastic equinus foot. This treatment seems to improve gait in hemiplegic patients when used alone or combined with an ankle-foot orthosis. However, the nature and effects of this improvement have until now rarely been studied. The aim of this study was to quantify the impact of a Botulinum toxin injection(More)
This pioneering observational study explored the interaction between subacute stroke inpatients and a rehabilitation robot during upper limb training. 25 stroke survivors (age 55 ± 17 years; time since stroke, 52 ± 21 days) with severe upper limb paresis carried out 16 sessions of robot-assisted shoulder/elbow training (InMotion 2.0, IMT, Inc., MA, USA)(More)
BACKGROUND High intensity and early initiation of rehabilitation have been extensively demonstrated to enhance neural plasticity and motor recovery after stroke. However, the optimal duration of rehabilitation programs in order to have the highest impact on motor outcomes has not been established. OBJECTIVES To evaluate motor outcomes in subacute stroke(More)
When increasing ambulation speed in Parkinson's disease, step cadence increases more than stride length, indicating movement scaling difficulties that affect step generation in particular. We investigated whether step length variation when increasing ambulation speed was related to disease progression. Patients with Parkinson's disease (N = 39) and controls(More)
