“…O uso do peso adicional tem apresentado resultados interessantes em diversas habilidades motoras precoces, como o aumento no sucesso de elevar um painel durante o movimento de chutes após a remoção imediata do peso em lactentes a termo e com Síndrome de Down (SANTOS et al, 2014); o aumento da frequência de chutes (CHEN et al, 2002); a diminuição dos picos de aceleração e desaceleração do braço, e o aumento da velocidade média no alcance manual em lactentes pré-termo de baixo risco (TOLEDO et al, 2012), além de proporcionar uma melhor sincronia entre os membros superiores em alcances bimanuais (ROCHA et al, 2009). Esses resultados são atribuídos principalmente ao aumento da propriocepção, da ativação neural, das unidades motoras e do recrutamento de fibras musculares, causados pelo peso adicional (CHEN et al, 2002;VAAL et al, 2002), além de favorecer a seleção de um padrão adaptativo mais eficiente e estável (OUT et al, 1997).…”

Resumo:Objetivo: Investigar o efeito do peso adicional nos ajustes proximais e distais do alcance em lactentes a termo (AT) e pré-termo tardios (PTT). Método: Foram avaliados 10 lactentes AT e 9 PTT dos 5 aos 7 meses de idade. As variáveis analisadas foram: a) ajustes proximais: unimanuais ou bimanuais; b) ajustes distais: abertura das mãos (aberta, fechada ou semiaberta) e orientação das mãos (horizontalizada, verticalizada ou oblíqua). Os procedimentos analisados foram: P1 (linha de base) e P2 (acréscimo de 20% da massa do membro superior de peso adicional). Para verificar a associação entre os procedimentos e as variáveis dependentes utilizou-se o Teste Qui-quadrado (p<0,05). Resultados: O peso adicional proporcionou a diminuição de alcances bimanuais aos 5 e 7 meses no grupo PTT, o aumento da frequência de mão verticalizada e a diminuição da frequência de mão aberta no início do movimento, aos 6 meses. No grupo AT, o peso implicou no aumento da mão verticalizada no início e no fim do movimento, aos 5 meses, e ao final do movimento, aos 7 meses, e diminuiu a frequência de mão aberta no início e final do alcance, aos 6 meses. Conclusão: O peso adicional favoreceu um movimento mais maduro na maioria das variáveis analisadas e, de forma mais expressiva, no grupo prematuro. Assim, pode tornar-se um instrumento para o treino inicial do alcance, quando o objetivo for a estimulação de alcances unimanuais com a mão verticalizada.Abstract: Objective: The aim of this work is to investigate the effects of additional weight in the proximal and distal adjustments of the reaching behavior of full-term and preterm infants. Method: We evaluated 10 full-term and 9 low risk preterm infants from 5 to 7 months age. The following variables were analyzed: a) proximal adjustments: unimanual or bimanual; b) distal adjustments: hand opening (open, closed, semi-open) and hand orientation (horizontal, vertical, oblique). Variables were analyzed in two procedures: P1 (baseline) and P2 (addition of 20% of the total mass of the infant's upper limb). To verify the association between procedures and dependent variables was applied Chi-Square Test (p<0,05). Results: Additional weight decreased of bimanual frequency for the preterm group at 5 and 7 months old, increased vertical hand frequency and decreased open hand frequency at 6 months. In the full-term group, additional weight increased the vertical hand frequency at the initiation and at the end of the movement at 5 months and at the end of the movement at 7 months. It also decreased open hand frequency at the initiation and at the end of the reaching at 6 months. Conclusion: Additional weight favored a more mature movement in the majority of variables analyzed, more expressively in the preterm group. Therefore, it can become an instrument of training this skill in the beginning of the reaching, when looking for verticalized hand unimanual reaching stimulation. licença Creative Commons Attribution Este é um artigo publicado em acesso aberto (Open Access) sob a licença Creative Commons At...

“…For instance, individuals with DS are often capable of walking and jumping, as well as fine motor skills and manual dexterity. Examples of functional motor development can be seen when special teaching strategies are implemented [19][20][21][22][23][24]. This demonstrates that individuals with DS are at least somewhat able to adapt to their motor impairments.…”

IntroductionAction and perception are two inherently linked aspects of human behavior that allow us to understand and interact with our surroundings. The interplay between action production and perception enables humans to act in a number of highly demanding situation such as unusual, novel or unstable environments [1]. Babies interact with their environment in a myriad of different ways such as imitation, selfmotion and observing the examples of others [2][3][4]. These interactions serve to shape not only their knowledge about the world, but also their understanding of the functionality of their bodies.Action performance interacts with action perception, and viceversa. This is reflected in the brain, as both performing and perceiving actions activate similar cortical areas [5]. Previous research has revealed significant interactions between action perception and action execution, and studies have shown that action perception can interfere with action execution reciprocally [6][7][8]. It is particularly insightful to study such interactions in populations with abnormal skeleto-muscular and/or neural development, as in these populations the brain may have adapted differently to handle physical differences, which in turn may influence how affected individuals interact with their surroundings. For example Sinha et al. [9] have shown that individuals with autism spectrum disorder, adapt their sensory input atypically, resulting in diverse behavioral traits. Down Syndrome (DS) is one of the most common genetic disorders (14 per 10 000 live births) caused by the presence of a complete or partial third copy of chromosome 21 (Trisomy 21) [10]. DS is a genetic change that impacts not only intellectual ability, but also motor development and motor control over the lifetime [11,12]. Abnormal brain functioning related to learning has been reveled in a number of studies [13][14][15][16]. In addition to neurodevelopmental abnormalities, corporal abnormalities are also common in DS. These abnormalities are highly related to the impaired motor control of voluntary movements [11,17].Children with DS require more time to learn basic movements. Additionally, as movement complexity increases they achieve gross motor functions at an average age that is almost twice that of typically developed children [18]. However, despite delays in motor development and the control of voluntary movements, the DS population does not exhibit a complete absence of the production of gross motor skills. For instance, individuals with DS are often capable of walking and jumping, as well as fine motor skills and manual dexterity. Examples of functional motor development can be seen when special teaching strategies are implemented [19][20][21][22][23][24]. This demonstrates that individuals with DS are at least somewhat able to adapt to their motor impairments. In more realistic tasks, Latash [11,17] argue that, when confronted with an unexpected or unclear motion situation, individuals with DS choose to act slowly (bradykinesia) during the initiation ph...

The authors analyzed and compared the effect of additional weight on the spatiotemporal parameters of the kicking movement of late preterm and full-term infants. The experiment was divided into 4 conditions: training, baseline, weight, and postweight. In the W condition, a weight of one third the lower limb mass was added to the infant's ankle. During the baseline and postweight conditions, the ankle weight was removed. Late preterm infants do not differ from full-term infants in relation to spatiotemporal variables at 3 and 4 months. However, during the weight condition, the straightness index and the hip-ankle and knee-ankle correlations decreased in the preterm infants at both ages. In contrast, the straightness index increased in the postweight condition compared to the baseline values at both ages.
