Measurements and quantitative analysis of kinematic parameters of human hand movements have an important role in different areas such as hand function rehabilitation, modeling of multi-digits robotic hands, and the development of machine-man interfaces. In this paper the assessment and evaluation of the reachto-grasp movement by using computerized and robot-assisted method is described. Experim...

BACKGROUND Patients with pronounced spasticity reveal difficulties in hand opening during the approaching grasping phase. The general description and assessment procedures of reach-to-grasp movement for rehabilitation purposes is still not established. There is a necessity to develop a universal methodology to describe the approaching phase in grasping which would allow clinical evaluation of m...

The study aimed at investigating the extent to which the brain adaptively exploits or compensates interaction torque (IT) during movement control in various velocity and load conditions. Participants performed arm pointing movements toward a horizontal plane without a prescribed reach endpoint at slow, neutral and rapid speeds and with/without load attached to the forearm. Experimental results ...

This study is part of a larger project investigating the individual and combined effects of word position, utterance length, and phonetic context on kinematic aspects of labial and mandibular movements during grammatically correct and semantically meaningful utterances. In the present study, the effects of word position and utterance length on kinematic measures of movement duration, movement e...

The colour-changing stimulus paradigm is based on a tacit assumption that kinematic attributes (velocity, movement direction) do not affect the detection of colour change (). In this study three experiments are reported that clearly demonstrate that the time needed to detect changes in colouration of a moving stimulus becomes shorter with its velocity. The reduction of reaction time with increa...

The visual perception system of humanoid robots should provide sensorial information that fulfills the requirements imposed by perceptual tasks in natural environments. One prerequisite for such systems is the ability to observe the environment by actively moving its visual sensors. This ability allows to implement two essential behaviors for a cognitive visual system: smooth pursuit and saccad...

Laban Movement Analysis (LMA) is a method for describing, interpreting and documenting all varieties of human movement. Analyzing movements using LMA is advantageous over kinematic description, as it captures their qualitative aspects in addition to the quantitative. Thus, in recent years, LMA is increasingly becoming the preferred method for movement analysis. In this study we developed a Mach...
