Hemiparetic patients often present an abnormal leg muscles balance that can lead to foot deformities like equinovarus or varus.To assess whether a muscle imbalance between tibialis anterior and extensor digitorum longus was associated with a varus deformity of the foot during the swing phase of gait in stroke patients.Twenty hemiparetic patients presenting a foot varus during the swing phase of gait...
This paper presents a novel reeducation device for paraplegics that combines hybrid orthoses and closed-loop electrical muscle stimulation. Based on the so called cyberthosis concept, the WalkTrainer enables an active muscular participation of the subject in the walking reeducation process by the mean of closed-loop muscle stimulation. The WalkTrainer is also equipped with a leg and pelvic orthosis,...
Pelvic motions are of great importance while walking, and have thus to be taken into account when developing and controlling rehabilitation devices. This paper will first introduce a new reeducation device for paraplegic people: the WalkTrainer. This device is composed of a leg and pelvic orthosis, an active bodyweight support and closed loop muscle stimulation. Second, the six degrees of freedom...
Pelvic motion is of great importance when walking, and have thus to be taken into account while developing rehabilitation robotics. This paper describes the implementation of a pelvic motion amplitude prediction model on a pelvic orthosis and tests on valid subjects. Furthermore over ground versus treadmill walking was also performed. For comparison averaged pelvic trajectories were tested against...
HIV-1 N-glycans are known to shield underlying epitopes towards the protective antibody repertoire. We previously described HIV-1 acute infection Env glycomutants designed from 3D-model in which the removal of clustered N-glycans did not disturb the envelope antigenicity, but increased the neutralization sensitivity. The potential of such immunogens to elicit neutralizing responses was estimated after...
