BACKGROUND Congenital hemiplegia is the most common form of cerebral palsy (CP) accounting for 1 in 1300 live births. These children have limitations in capacity to use the impaired upper limb and bimanual coordination deficits which impact on daily activities and participation in home, school and community life. There are currently two diverse intensive therapy approaches. Traditional therapy ...

The availability of consumer-facing virtual reality (VR) headsets makes training an attractive alternative to expensive traditional training. Recent works showed that virtually trained workers perform bimanual assembly tasks equally well as ones with methods. This paper presents a study investigated how levels immersion affect learning transfer between and physical gearbox tasks. used with-in s...

The purpose of this study was to investigate force variability generated by both the paretic and non-paretic hands during bimanual force control. Nine chronic stroke individuals and nine age-matched individuals with no stroke history performed a force control task with both hands simultaneously. The task involved extending the wrist and fingers at 5%, 25%, and 50% of maximum voluntary contracti...

This third paper in a series of three related developmental trajectories of bimanual object acquisition and non-differentiated bimanual manipulation (NDBM) to patterns of role-differentiated bimanual manipulation (RDBM) development to help identify the sequence of events that might predict (and potentially facilitate) the development of RDBM skill. Ninety infants were tested monthly from 6 to 1...

Bimanual microincisional cataract surgery has been introduced recently as a technique for cataract surgery and it is gaining interest of many cataract surgeons in the world. Over the last few years many changes were made in the phacoemulsification machines and the intraocular lenses design which allowed bimanual microincisional cataract surgery to be safer and more efficient. The purpose of thi...

Two-handed interaction is a very common paradigm that is gaining popularity in the fields of medical tele-operation, gaming, and large-scale design. In this paper, we validate Guiard’s theory of bimanual control for the tasks of navigation and selection. We present the related literature and the theoretical models that motivate the research, in particular Guiard’s theory of bimanual control. Tw...

Research has shown that bimanual (two-handed) interfaces often provide more intuitive, efficient, and comfortable interaction than one-handed interfaces. This paper introduces a new input technique, bimanual marking menus, and compares its performance with five other techniques: static toolbars, hotkeys, grouped hotkeys, marking menus, and toolglasses. The study builds on previous work by setti...

INTRODUCTION Bimanual hand coordination is very important in carrying out day to day activities like buttoning the shirt, driving, picking up objects. It depends on various factors like age, gender, education, intactness of central and peripheral nervous system, Occupation and lifestyle. AIM The aim of the study was to compare the efficiency of bimanual hand coordination between right handed ...

The bimanual advantage refers to the finding that tapping with two fingers on opposite hands exhibits reduced timing variability, as compared with tapping with only one finger. Two leading theories propose that the bimanual advantage results from the addition of either sensory (i.e., enhanced feedback) or cognitive (i.e., multiple timekeeper) processes involved in timing. Given that crossing th...
