Although blast injuries are common with war; cooking gas; firecracker, mobile phone blast cases are increasing in number in last couple of years. We present 3 cases of mobile blast in 3 children causing injury to dominant hand in them.

BACKGROUND According to decades of research on affective motivation in the human brain, approach motivational states are supported primarily by the left hemisphere and avoidance states by the right hemisphere. The underlying cause of this specialization, however, has remained unknown. Here we conducted a first test of the Sword and Shield Hypothesis (SSH), according to which the hemispheric lat...

[Purpose] The purpose of this study was to compare the reaching velocity of the upper trunk and the center of force (COF) during a reaching task with the dominant and nondominant hands. [Subjects] Ten males between the ages of 20 and 30 years participated in this study. [Methods] This study measured the reaching velocity, upper trunk movement, and center of force movement during a reaching task...

BACKGROUND Low hand grip strength is a strong predictor for both long-term and short-term disability and mortality. The Nintendo Wii Balance Board (WBB) is an inexpensive, portable, wide-spread instrument with the potential for multiple purposes in assessing clinically relevant measures including muscle strength. The purpose of the study was to explore intrarater reliability and concurrent vali...

BACKGROUND The decline of motor performance of the human hand-arm system with age is well-documented. While dominant hand performance is superior to that of the non-dominant hand in young individuals, little is known of possible age-related changes in hand dominance. We investigated age-related alterations of hand dominance in 20 to 90 year old subjects. All subjects were unambiguously right-ha...

The present study examines the effects of a four-week training session in a pegboard task on uniand bimanual performance. Of particular interest was whether practice transfer from the trained to the untrained hand takes place. Twenty-five consistently right-handed subjects were trained to perform the task with the dominant hand, or the subdominant hand, or with both hands. After this training, ...

The issue of handedness has been the topic of great interest for researchers in a number of scientific domains. It is typically observed that the dominant hand yields numerous behavioral advantages over the non-dominant hand during unimanual tasks, which provides evidence of hemispheric specialization. In contrast to advantages for the dominant hand during motor execution, recent research has d...

OBJECTIVE To determine reliability of maximal grip strength, muscle coordination and muscle endurance. To compare these parameters in young adults with unilateral cerebral palsy and healthy subjects. To evaluate the correlation of these variables with functional activities. SUBJECTS Twenty-six healthy subjects and 26 young adults with unilateral cerebral palsy recruited from a cohort study in...

Amputation of the dominant hand forces patients to use the nondominant hand exclusively, including for tasks (e.g., writing and drawing) that were formerly the sole domain of the dominant hand. The behavioral and neurological effects of this chronic forced use of the nondominant hand remain largely unknown. Yet, these effects may shed light on the potential to compensate for degradation or loss...

Co-ordinated bi-manual actions form the basis for many everyday motor skills. In this review, the internal model approach to the problem of bi-manual co-ordination is presented. Bi-manual coordinative tasks are often regarded as a hallmark of complex action. They are often associated with object manipulation, whether the holding of a single object between the two hands or holding an object in e...
