The performance of brain-machine interfaces (BMIs) that continuously control upper limb neuroprostheses may benefit from distinguishing periods of posture and movement so as to prevent inappropriate movement of the prosthesis. Few studies, however, have investigated how decoding behavioral states and detecting the transitions between posture and movement could be used autonomously to trigger a ...

BACKGROUND AND OBJECTIVE Motor control of the upper extremity during unilateral and bimanual functional tasks and functional change during daily activities were evaluated in patients with stroke treated with modified constraint-induced movement therapy (mCIMT). METHODS In a pre-post randomized, controlled trial, 30 stroke patients received 2 hours of mCIMT or traditional rehabilitation (TR) f...

This clinical note describes a typical case of dynamic varus deformity of the hind part of the foot in a head injured adult. Gait analysis objectified, by kinematic data, the perturbed movement of the rear foot in the frontal plane and identified, by dynamic electromyography, the overactive muscle (posterior tibialis) involved in the deformity. The diagnosis was confirmed by a motor point block...

This paper presents a novel generalized computational framework for quantitative kinematic evaluation of movement in a rehabilitation clinic setting. The framework integrates clinical knowledge and computational data-driven analysis together in a systematic manner. The framework provides three key benefits to rehabilitation: (a) the resulting continuous normalized measure allows the clinician t...

The three dimensional (3D) reconstruction of movement from videos is widely utilized as a method for spatial analysis of movement. Several approaches exist for a 3D reconstruction of movement using 2D video projection, most of them require the use of at least two cameras as well as the application of relatively complex algorithms. While a few approaches also exist for 3D reconstruction of movem...

BACKGROUND Practitioners need more sensitive measures to quantify reaching movement for judgement of the treatment effects and reflecting the degrees of motor impairment in upper extremities. OBJECTIVE The purposes of this study were to differentiate between spastic and normal reaching using three-dimensional (3D) motion analysis and to quantify the interference of spasticity on reaching move...

This paper concerns the analysis of the screw theory-based kinematic modeling in order to ease the programming process. To do so, an object-oriented computational framework is developed from this analysis. Screw theory and related tools are well used in motion analysis of open and closed kinematic chains, typical of robotic manipulators, in an uniform and systematic way. Their use in the invers...

This work provides information on the blue fox ejaculated sperm quality needed for seminal dose calculations. Twenty semen samples, obtained by masturbation, were analyzed for kinematic and morphometric parameters by using CASA-Mot and CASA-Morph system and principal component (PC) analysis. For motility, eight kinematic parameters were evaluated, which were reduced to PC1, related to linear va...

It is currently unclear whether the brain plans movement kinematics explicitly or whether movement paths arise implicitly through optimization of a cost function that takes into account control and/or dynamic variables. Several cost functions are proposed in the literature that are very different in nature (e.g., control effort, torque change, and jerk), yet each can predict common movement cha...
