The leading joint hypothesis (LJH) offers a novel interpretation of control of human
movements that involve multiple joints. The LJH makes control of each multijoint movement …

Although a number of upper limb kinematic studies have been conducted, no review actually
addresses the key-features of open-chain upper limb movements after cervical spinal cord …

Several years ago, our research group forwarded a model of goal-directed reaching and
aiming that describes the processes involved in the optimization of speed, accuracy, and …

Study design: Descriptive control case study. Objectives: To analyze the kinematics of
tenodesis grasp in participants with C6 quadriplegia and healthy control participants in a …

The aim of this study was to correlate clinical and functional evaluations with kinematic
variables of upper limp reach-to-grasp movement in patients with tetraplegia. Twenty chronic …

Nowadays touch technology is growing and developers try to make it ever more intuitive and
easier to use. This present work focused on the upper limb joint coordination during the …

Background While upper-extremity movement in individuals with neurological disorders
such as stroke and spinal cord injury (SCI) has been studied for many years, the effects of …

In this work, it is proposed to evaluate the upper-limb movements through a global index of
performance borrowed from the field of robotics: the manipulability. For a given posture, this …

Regaining upper extremity function is the primary concern of persons with tetraplegia
caused by spinal cord injury (SCI). Robotic rehabilitation has been inadequately tested and …

We have previously shown that the Coriolis torques that result when an arm movement is
performed during torso rotation do not affect movement trajectory. Our purpose in the …
