PURPOSE To evaluate clinical outcomes of limbal relaxing incision (LRI) combined with bimanual phacoemulsification and insertion of an intraocular lens (IOL) developed for bimanual microincision cataract surgery (MICS). METHODS In a prospective, single-center study, eyes with > or = 0.75 diopters (D) of keratometric astigmatism were randomly assigned to two surgical techniques: 1) bimanual MI...

[Purpose] To evaluate the relationships between residual strength deficits (RSD) of the upper limb muscles and the performance in bimanual activities and to determine which muscular group would best explain the performance in bimanual activities of chronic stroke individuals. [Subjects and Methods] Strength measures of handgrip, wrist extensor, elbow flexor/extensor, and shoulder flexor muscles...

OBJECTIVE To compare patients' acceptance of and correlate their pain level for bimanual versus metal speculum fixation in intravitreal injections. DESIGN Prospective analysis. PARTICIPANTS Seventy-three eyes of 56 patients. METHODS A questionnaire indicating patients' discomfort and pain grading immediately after intravitreal injections using either bimanual fixation or metal speculum fi...

BACKGROUND Cervical Spinal Manipulation (CSM) is considered a high-level skill of the central nervous system because it requires bimanual coordinated rhythmical movements therefore necessitating training to achieve proficiency. The objective of the present study was to investigate the effect of real-time feedback on the performance of CSM. METHODS Six postgraduate physiotherapy students atten...

To determine the factors that ensure successful and complete implementation of proposed simulation tasks, a “boxed” simulator was taken to work out bimanual manipulations skills with needle-holder Lapsim simulator. A computer allows high level reliability stages surgical interventions, use anatomical situations various levels complexity, orientation skill in two -dimensional space, master video...

Bimanual actions impose intermanual coordination demands not present during unimanual actions. We investigated the functional neuroanatomical correlates of these coordination demands in motor imagery (MI) of everyday actions using functional magnetic resonance imaging (fMRI). For this, 17 participants imagined unimanual actions with the left and right hand as well as bimanual actions while unde...

Corpus callosum (CC) is involved in the performance of bimanual motor tasks. We asked whether its functional role could be investigated by combining a motor behavioral study on bimanual movements in multiple sclerosis (MS) patients with a quantitative magnetic resonance diffusion tensor imaging (DTI) analysis of CC, which is shown to be damaged in this disease. MS patients and normal subjects w...

Bradykinesia is a well-documented DOPA-responsive clinical feature of Parkinson's disease (PD). While amplitude deficits (hypokinesia) are a key component of this slowness, it is important to consider how dopamine influences both the amplitude (hypokinesia) and frequency components of bradykinesia when a bimanually coordinated movement is required. Based on the notion that the basal ganglia are...

Hinder MR. Interhemispheric connectivity between distinct motor regions as a window into bimanual coordination. J Neurophysiol 107: 1791–1794, 2012. First published November 30, 2011; doi:10.1152/jn.00822.2011.—Performing coordinated bimanual movement is a fundamental feature of the human motor system, with imaging techniques revealing the involvement of an extensive network of motor regions in...

Bimanual actions are ubiquitous in daily life. Many coordinated movements of the upper extremities rely on precise timing, which requires efficient interhemispheric communication via the corpus callosum (CC). As the CC in particular is known to be vulnerable to traumatic brain injury (TBI), furthering our understanding of its structure-function association is highly valuable for TBI diagnostics...
