Anatomic, Functional and Cognitive Asymmetries in Monozygotic Twins With Discordant Handedness
(Yuzuncu Yil Universitesi Tip Fakultesi, 2014) Erkec, O.E.; Yetkin, Y.
Discordant handedness was observed at a higher rate than expected in monozygotic (MZ) twins. This study was designed to investigate the degree of asymmetry in terms of anatomical, functional (motor) and cognitive (IQ and visual memory) features on 27 MZ twins for discordant handedness according to Edinburgh Handedness Inventory (EHI). There was statistically significant difference between EHI and Yetkin Laterality Questionnaire (YLQ). Ambidextrous were found lack of cerebral dominance. Both left and right handed subjects were found left hemisphere dominance. There was no significant difference in terms of anatomic or cognitive features between MZ twin members with discordant handedness. © 2014, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Evaluation of Relationships Between Postural and Functional Lateral Preferences and Chewing Side Among Students in Eastern Turkey
(Yuzuncu Yil Universitesi Tip Fakultesi, 2019) Erkec, O.E.; Keskin, S.
This study aims to evaluate the relationships between postural and functional lateral preferences and the preferred chewing side among young subjects. Functional lateral preferences, postural lateral preferences and the preferred chewing side were assessed in 376 young individuals (178 men, 198 women, mean age: 20.07). Of the 376 individuals, 31.1 % were strong right-handers, 58.8 % were weak right-handers, 2.9% were ambidextrous, 5.9% were weak left-handers, 1.3% was strong left-handers. There was a right-side preference for handedness (89.9%), footedness (75.8%), earedness (59.2%), eyedness (paper tube test, 70.0%), eyedness (Rosenbach dominant eye test, 62.9%), hand clapping (78.4%), leg-crossing (64.4%), preferred chewing side (60.9%) and a left-side preference for hand-clasping (55.2%), and arm-folding (55.3%). Only eyedness (paper tube test) differed between the genders; women mostly preferred the left eye when looking through the paper tube. Handedness, footedness, earedness, and eyedness (paper tube) were each related with hand-clapping, however not with hand clasping and arm folding. In addition, hand clapping and leg crossing (but not hand clasping and arm folding) were each related to preferred chewing side. In general, individuals who preferred the right side were right sided in all of the variables, while individuals who preferred the left side were closely related to individuals who preferred both sides. Thus, it can be concluded that individuals who preferred the left side tended to be mostly bilateral, compared with individuals who preferred only the right side. These results may bring insight into the relationships between functional and postural lateral preferences and the preferred chewing side for the young population. © 2019, Yuzuncu Yil Universitesi Tip Fakultesi.
