“…Five stroke participants had right hemispheric MCA strokes and eight had left hemispheric MCA strokes. All participants were tested for hand dominance based on the Edinburgh Handedness Inventory (68), and were right-handed. All control participants were right-handed.…”

Eye Control Deficits Coupled to Hand Control Deficits: Eye–Hand Incoordination in Chronic Cerebral Injury

et al. 2017

It is widely accepted that cerebral pathology can impair ocular motor and manual motor control. This is true in indolent and chronic processes, such as neurodegeneration and in acute processes such as stroke or those secondary to neurotrauma. More recently, it has been suggested that disruptions in these control systems are useful markers for prognostication and longitudinal monitoring. The utility of examining the relationship or the coupling between these systems has yet to be determined. We measured eye and hand-movement control in chronic, middle cerebral artery stroke, relative to healthy controls, in saccade-to-reach paradigms to assess eye–hand coordination. Primary saccades were initiated significantly earlier by stroke participants relative to control participants. However, despite these extremely early initial saccades to the target, reaches were nevertheless initiated at approximately the same time as those of control participants. Control participants minimized the time period between primary saccade onset and reach initiation, demonstrating temporal coupling between eye and hand. In about 90% of all trials, control participants produced no secondary, or corrective, saccades, instead maintaining fixation in the terminal position of the primary saccade until the end of the reach. In contrast, participants with stroke increased the time period between primary saccade onset and reach initiation. During this temporal decoupling, multiple saccades were produced in about 50% of the trials with stroke participants making between one and five additional saccades. Reaches made by participants with stroke were both longer in duration and less accurate. In addition to these increases in spatial reach errors, there were significant increases in saccade endpoint errors. Overall, the magnitude of the endpoint errors for reaches and saccades were correlated across participants. These findings suggest that in individuals with otherwise intact visual function, the spatial and temporal relationships between the eye and hand are disrupted poststroke, and may need to be specifically targeted during neurorehabilitation. Eye–hand coupling may be a useful biomarker in individuals with cerebral pathology in the setting of neurovascular, neurotraumatic, and neurodegenerative pathology.

“…The EHI is a self-report measure that assesses hand preference for common gross motor activities, such as writing, throwing, or using a pair of scissors. Following the recommendations of Dragovic (2004) and Edlin et al (2015), we used a modified version of the EHI, characterized by the following changes: BUsing a broom^was replaced with Bcombing hair^; Bopening a box lid^was replaced with Bopening a jar^; and a 5-point response scale was used, with the assignment of the following scores: Always right (+10), usually right (+5), no preference (0), usually left (-5), and always left (-10).…”

The contributions of handedness and working memory to episodic memory

2016

Past studies have independently shown associations of working memory and degree of handedness with episodic memory retrieval. The current study takes a step ahead by examining whether handedness and working memory independently predict episodic memory. In agreement with past studies, there was an inconsistent-handed advantage for episodic memory; however, this advantage was absent for working memory tasks. Furthermore, regression analyses showed handedness, and complex working memory predicted episodic memory performance at different times. Results are discussed in light of theories of episodic memory and hemispheric interaction.

“…36 Both types are useful, but the questionnaire type invariably has the advantage of being faster and easier to administer. 35 Furthermore, inventory scores correlate sensibly with performance measures as well as with differential activity in the motor cortex regions, which supports their validity.…”

“…6 There are also well-established studies showing the relationship between handedness and brain morphology in specific regions. 35 The other type is a test of manual dexterity, the Purdue Pegboard test, which assesses the motor performance of each hand. 36 Both types are useful, but the questionnaire type invariably has the advantage of being faster and easier to administer.…”
