OBJECTIVES Our study determined whether depth perception defects and hand-eye dominance affect an individual's ability to perform laparoscopic skills. METHODS The study cohort comprised 104 third-year medical students from LSU School of Medicine who completed a questionnaire including information on handedness and were tested for eye dominance and depth perception by using standardized method...

Hemispheric lateralization for language production and its relationships with manual preference and manual preference strength were studied in a sample of 297 subjects, including 153 left-handers (LH). A hemispheric functional lateralization index (HFLI) for language was derived from fMRI acquired during a covert sentence generation task as compared with a covert word list recitation. The multi...

The aim of this retrospective study was to assess the presence of a possible association between handedness and the side of symptom dominance in 963 patients with Parkinson's disease (PD). In only 287 patients the hand dominance was registered. Out of 254 right-handed patients, 158 (62%) had a right-side dominance of PD symptoms, while 96 patients (38%) had left-lateralized symptom dominance (p...

BACKGROUND Hand grip strength in both the dominant and non-dominant hands is often used to assess upper limb impairment. Excessive hand grip fatigability is another important measure, as fatigability may also influence activities of daily living. OBJECTIVE To investigate to what extent hand grip fatigability in multiple sclerosis is dependent on hand dominance, muscle strength and disease pro...

In this study, which investigates the relationship between the levels of stereopsis with eye and hand dominance or interpupillary distance, 120 healthy young volunteers were investigated. Eye dominance was determined by modified Miles technique following a complete eye examination. Handedness was assessed with the Edinburgh handedness inventory. Interpupillary distance was measured with millime...

Objective: The purpose of this study is to examine the association between hand preference in young healthy individuals and handgrip strength (HGS), (which is accepted to be an objective measurement in the assessment of gender), 2D:4D ratio (ratio of the length of index finger to that of ring finger), eye dominance and upper limb performance. Methods: A total of 198 individuals, 111 males and 8...

Brain lateralization is a common term used to describe dominance of one brain hemisphere over another for a specific function. The right hand dominance in writing, controlled by the left hemisphere, is preceded by development of communicative gesticulation and followed by development of speech in the same hemisphere. We assumed that some people are not aware of their own capability of using the...

Background: Hand-grip strength studies with healthy adults have shown correlation between anthropometric variables and hand grip strength. There is dearth in literature in population of Saudi Arabia. The objective of this study is to describe normative data to evaluate the relationship between handgrip strength and other anthropometric variables especially hand length, forearm circumference wit...
