a b s t r a c tIn birds, a lateralised visual input during early development importantly modulates morphological and functional asymmetries of vision. We tested the hypothesis that human handedness similarly results from a combination of inborn and experience-driven factors by analysing sidedness in children suffering from congenital muscular torticollis. These children display a permanently tilted asymmetric head posture to the left or to the right in combination with a contralateral rotation of face and chin, which could lead to an increased visual experience of the hand contralateral to the head-tilt. Relative to controls, torticollischildren had a higher probability of right-or left-handedness when having a head-tilt to the opposite side. No statistical significant relation between head position and direction of functional asymmetries was found for footedness and eye-preference, although the means show a non-significant trend in the same direction as was observed for handedness. Thus, an increased visual control of the hand during early childhood seems to modulate handedness and possibly other lateral preferences to a lesser extent. These findings not only show that human handedness is affected by early lateralised visual experience but also speak in favour of a combined gene-environment model for its development.

“…Footedness has been considered more sensitive than handedness as a behavioral index of hemispheric lateralization in terms of emotional perception and language organization 4,5 . Sadeghi et al 4 recommended consideration of the preferentially-used foot in performing a specific motor task as a strategy to identify footedness.…”

“…Strategies to observe which foot is chosen to manipulate or move an object, when required to kick a ball, or to pick up a marble from the floor with the toes, could more precisely help identify the footedness. With this approach, the foot used to support the body weight would be considered the non-dominantly used 3,4,5 .…”

“…It is easy to apply but had not been translated and cross-culturally adapted for the Brazilian population 5 . Despite footedness having been related to functional asymmetries, studies considering the effects of footedness on gait and postural control for able-bodied people have presented divergent results, creating doubts about similarities or disparities coming from the preference referred to by performing tasks or performing weight support 4,6 .…”

Post-stroke hemiparesis causes compensated postures, which can modify the footedness established before the impairment. Recently, a paresis severity-modulated dominance hypothesis stated that measures to detect footedness become crucial to float new ideas for neurorehabilitation strategies. The Waterloo Footedness Questionnaire-Revised (WFQ-R) represents the most acceptable measure but it had not yet been cross-culturally adapted for Portuguese spoken in Brazil. Our aim was to cross-culturally adapt the WFQ-R to Brazilian Portuguese, verifying its reliability. We completed the essential steps to cross-culturally adapt one version, tested in 12 patients with post-stroke hemiparesis and 12 able-bodied individuals, sampled by convenience, to verify reliability. Measurements were taken by two independent raters during the test and by one of them at the one-week retest. No great semantic, linguistic or cultural differences were found, and acceptable reliability was recorded. The WFQ-R-Brazil is reliable and ready for use in the Brazilian able-bodied and post-stroke hemiparesis population.Keywords: diagnosis; monitoring; hemiplegia. RESUMOHemiparesia pós-doença cerebrovascular causa posturas compensadas que podem modificar predominância de uso do pé adotada antes da deficiência. Recentemente, hipótese de predominância modulada pela gravidade da paresia declara que medidas para detectar predominância tornaram-se cruciais para sugerir ideias em busca de estratégias de neurorreabilitação. A Waterloo Footedness Questionnaire-Revised (WFQ-R) representa a medida mais aceita e não foi ainda adaptada transculturalmente para o Português brasileiro. Nosso objetivo foi então adaptar o WFQ-R, verificando sua confiabilidade. Nós completamos os passos essenciais para adaptar uma versão testada em 12 pessoas com hemiparesia e 12 fisicamente aptas amostradas por conveniência para procedimentos de verificação da confiabilidade. Medidas foram tomadas por dois examinadores independentes durante o teste e por um deles no reteste após uma semana. Nenhuma diferença semântica, linguística ou cultural foi encontrada, e confiabilidade aceitável foi registrada. WFQ-R-Brasil é confiável e está pronto para uso na população de brasileiros fisicamente aptos e com hemiparesia.Palavras-chave: diagnóstico; monitoramento; hemiplegia Right or left brain asymmetries have been demonstrated in studies of complex cognitive functions such as musical abilities, language, emotions, and visuospatial tasks 1 . Mutha et al. 2 defended that a hemispheric specialization model, in which unilateral hemispheres become responsible through different motor control mechanisms, decreases the energy expenditure and time for communication between processing units (efficiency), optimizing performance. With this rationale, the asymmetry of performing different tasks by choosing a preferred hand or foot

Fluctuating asymmetry (FA) refers to random, small deviations from perfect bilateral symmetry in morphological traits. These minor deviations from the ideal phenotype reflect environmental and genetic perturbations experienced during ontogeny. FA has been associated with negative health outcomes and many developmental disorders in humans. The prevalence of developmental disorders and adult health vary according to the month of birth, suggesting that seasonal stressors may leave enduring signs in the adult body, marked by high FA. The current study examined the relationship between FA and birth season. Data were collected for 205 males and females (average age = 20.39 years) on FA of 10 bilateral traits (second, third, fourth, and fifth digit length, palm height, wrist diameter, elbow width, ear height, foot breadth, and ankle circumference). Additional relationships were also investigated among FA, testosterone (T), and birth order. Results indicate that ear FA was lower for fall births compared to winter births in males. In females, palm FA was lower for fall births compared to those of the spring. FA of the digits was positively associated with T in males. Average FA, excluding the digits, decreased as the number of maternal siblings increased for both sexes. T concentrations in males were positively associated with the number of younger brothers. Our results generally confirm previous research on seasonal variation in adult longevity and neurological and psychiatric disorders, suggesting that winter and spring births are at risk for asymmetric developmental trajectory.
