Grasping and manipulation by hands can be considered as one of inevitable functions to achieve the performances desired in humanoid operations. When a humanoid robot manipulates an object by his hands, each finger should be well-controlled to accomplish a precise manipulation of the object grasped. So, the trajectory of each joint required for a precise finger motion is fundamentally necessary ...

Acquisition of good quality training samples is becoming a major issue in machine learning based human motion analysis. This paper presents a method to simulate human body motion with the intention to establish a human motion corpus for learning and recognition. The simulation is achieved by a unique temporal-spatial-temporal decomposition of human body motion into actions, joint actions and ac...

This paper presents a novel approach to plan the optimal joint trajectory for a manipulator robot performing constrained motion tasks. In general, a two-step scheme will be deployed to find the optimal robot joint curve. Firstly, instead of solving a nonlinear, implicit EulerLagrange equation, we discretize the corresponding cost function and use Newton’s iterations to numerically calculate the...

Background. Consider the fact that the implementation of aerobic exercise can be effective in the learning and acquisition process, and that training athletes to acquire new skills is appropriately done in terms of the primacy and recency of the training time for aerobic activities such as the warm-up. Objectives. The purpose of the present study was to investigate the effect of moderate-inten...

BACKGROUND It is commonly believed that early motion after joint fixation is advantageous, especially in the upper limb. In the ankle joint this is much less clear. No previous systematic review of the evidence for this could be found in the literature. MATERIALS AND METHODS Nine randomized control trials were identified which met the inclusion criteria and compared early motion of the ankle ...

Introduction: Application of biofeedback techniques in rehabilitation has turned into an exciting research area during the recent decade. Providing an appropriate visual or auditory biofeedback signal is the most critical requirement of a biofeedback technique. In this regard, changes in Surface Electromyography (SEMG) signals during wrist movement can be used to generate an indictable visual b...
