Unconstrained three-dimensional reaching in Rhesus monkeys

Grégoire Courtine

To better understand normative behavior for quantitative evaluation of motor recovery after injury, we studied arm movements by non-injured Rhesus monkeys during a food-retrieval task. While seated, monkeys reached, grasped, and retrieved food items. We re ...

Near infrared spectroscopy (NIRS) can readily report on changes in blood volume and oxygenation. However, it has proved more problematic to measure real-time changes in blood flow and oxygen consumption. Here we report the development of a novel method usi ...

NMR Properties of Human Median Nerve at 3 T: Proton Density, T1, T2, and Magnetization Transfer

Giulio Gambarota

Purpose: To measure the proton density (PD), the T1 and T2 relaxation time, and magnetization transfer (MT) effects in human median nerve at 3 T and to compare them with the corresponding values in muscle. ...

The WalkTrainer, a New Generation of Walking Reeducation Device Combining Orthoses and Muscle Stimulation

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Jacques Fournier, Yves Allemand

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 ...

We performed a whole-body mapping study of the effect of unilateral muscle vibration, eliciting spindle Ia firing, on the control of standing and walking in humans. During quiet stance, vibration applied to various muscles of the trunk-neck system and of t ...

Stretch-elicited intracellular calcium (Ca(2+)) changes in individual smooth muscle cells in a ring of aorta were measured simultaneously with the force developed by the ring. A phasic increase in Ca(2+) was observed in 30% of the cells and a sus ...

Coordinated modulation of locomotor muscle synergies constructs straight-ahead and curvilinear walking in humans

Grégoire Courtine

We describe the muscle synergies accompanying steering of walking along curved trajectories, in order to analyze the simultaneous control of progression and balance-threatening emerging forces. For this purpose, we bilaterally recorded in ten subjects the ...

This thesis is the first to be carried out within the framework of the project "Cyberthosis for Paraplegics" in progress at the "Laboratoire de Systèmes Robotiques" (LSRO) of the "Ecole Polytechnique Fédérale de Lausanne" (EPFL). This project, initiated in ...

Performance of locomotion and foot grasping following a unilateral thoracic corticospinal tract lesion in monkeys (Macaca mulatta)

Grégoire Courtine

Six adult monkeys (Macaca mulatta) received a unilateral lesion of the lateral corticospinal tract (CST) in the thoracic spinal cord. Prior to surgery, the animals were trained to perform quadrupedal stepping on a treadmill, and item retrieval with the foo ...

Human walking along a curved path. II. Gait features and EMG patterns

Grégoire Courtine

We recorded basic gait features and associated patterns of leg muscle activity, occurring during continuous body progression when humans walked along a curved trajectory, in order to gain insight into the nervous mechanisms underlying the control of the as ...
