“…Desta forma, indivídu-os com deficiência visual, que estão privados deste tipo de informação sensorial e, consequentemente estão mais instáveis, podem ter maior facilidade em manutenção da postura ereta correta 18 . Nesse caso, a supressão visual e a instabilidade postural são compensadas pela estimulação de outras áreas sensoriais 19 .…”

Objetivo. Avaliar os benefícios da fisioterapia aquática nas capacidades musculoesqueléticas e cardiorrespiratórias e no índice de qualidade de vida (QV) em um deficiente visual. Método. A amostra foi composta de um indivíduo portador de deficiência visual adquirida, de 50 anos, sem comprometimentos neuromusculoesqueléticos. Foram utilizados: a dinamometria de preensão palmar para avaliação da força muscular de membros superiores, o teste de oito repetições máximas para os membros inferiores; o Banco de Wells para flexibilidade; o teste de velocidade de marcha para funcionalidade; a espirometria para força dos músculos inspiratórios e expiratórios e o questionário WHOQOL BREF para qualidade de vida. Após a construção de um protocolo de exercícios com comandos áudio-táteis, os mesmos foram aplicados por 12 semanas, duas vezes por semana, durante 60 minutos. Resultados. Aumento de 5,2% na força muscular de membros superiores e 30% de membros inferiores. O ganho de flexibilidade foi de 100%, refletindo em melhora de 25 milissegundos no teste de velocidade de marcha. A força muscular inspiratória obteve ganho de 57,1% a melhora de QV total foi de 5,7%. Conclusão. Um protocolo de hidrocinesioterapia adaptado a deficientes visuais foi eficaz na promoção de ganhos físico funcionais e de QV de um deficiente visual.

“…), but also can originate intrinsically (i.e., the presence of developmental disabilities or degenerative conditions). Postural instability has been investigated from a perception-action approach relative to the role sensory cues play on it in older individuals (Prioli et al, 2006), in congenitally blind people (Easton, Greene, DiZio, & Lackner, 1998;Jeka et al, 1996), and in individuals with Down syndrome (Gomes & Barela, 2007).Several systems-the visual, vestibular, proprioceptive, and haptic-take part in the evolution of the postural system. In early studies of haptic sensitivity, 1 researchers focused on the acquisition of information through the exploratory actions of the hands (Cooper, Carello, & Turvey, 2000;Solomon & Turvey, 1988).…”

This study assessed the effects of haptic information on the postural control systems of individuals with intellectual disabilities (ID), through the use of a nonrigid tool that we call the "anchor system" (e.g., ropes attached to graduated weights that rest on the floor). Eleven participants with ID were asked to stand, blindfolded, on a balance beam placed at two heights (10 and 20 cm), for 30 s, while using the anchor system at two weights. The lighter anchor weight appeared to improve the individuals' balance in contrast to a control task condition; therefore, we concluded that haptic sensitivity was more significant in helping to orient the body than was the anchor's mechanical support alone.Individuals with intellectual disability (ID) invariably exhibit poor or delayed postural adjustments at early stages; and, while many eventually acquire most fundamental motor milestones (e.g., upright position, walking, and running), they continue to experience balance problems as they age (Mauerberg-deCastro & Kinzler, 2000). Individuals with ID, such as Down syndrome, are known to have slower reactions to perturbations to posture, regardless of their ages (Shumway-Cook & Woollacott, 1985). Carvalho and Almeida (2009) demonstrated that individuals with Down syndrome adopted a pattern of cocontraction in their leg muscles, making them unable to modulate the magnitude of postural response to a task with varied degrees of instability. This finding reflects a proprioceptive deficit for this group. In addition, as individuals with ID age, lifestyle and health-related problems also contribute to postural instability and often increase the risk of falls and of loss Stabilization of Posture and Intellectual Disability 209 of independence (Hale, Bray, & Littmann, 2007). Lahtinen, Rintala, and Malin (2007), reporting a 30-year longitudinal study of individuals with ID, found that in adolescence, 25% of the ID participants were able to complete a static balance task (standing on one foot for 60 s, i.e., stork stand test); in adulthood the total of those who could perform the task dropped to less than 10%.Researchers have focused on causes for poor balance skills found in adults with ID, as well as on the adaptation process underlying postural control. Knowledge about the role of sensory information on postural control in groups that are known to have poor balance, for example, has added to our understanding of how, under a perception-action approach, sensory-motor mechanisms function (Gomes & Barela, 2007;Jeka, Easton, Bentzen, & Lackner, 1996;Prioli, Cardozo, Freitas Junior, & Barela, 2006). Numerous researchers have investigated how postural sway can be attenuated through an individual's acquisition of additional sensory information (somatosensory or visual;Jeka & Lackner, 1994;Jeka et al., 1996) or by the introduction of task demands to a challenged postural system (Prioli et al., 2006). Sources of postural disruptions can be task-manipulated (i.e., unexpected surface displacement, blindfolding of the participant, etc.), but...

Abstract. According to Latvia's statistical data, for the first time during the period from 2005 up to 2011, more than 3115 people were registered with the eye and it's parts diseases. The aim of the study was to assess postural parameter for people with severe visual impairment. The study involved visually impaired Social Care Center "JUGLA" occupiers, with the 1 st and the 2 nd visual impairments disability group. Participants were interviewed, posture was assessed (Kendall) and anthropometric measurements were taken. The majority -53.6% the study participants were 1 st group visual handicaps (mean age 47.9 ± 10.6 years). 82.1% the study participants had a straight backbone in the frontal plane. The cervical spine of 10.7% the participants had a normal position in the sagittal plane, for 32.1% the participants normal position was observed in the thoracic spine and for 39.3% -in lumbar spine. Faulty postural alignment in frontal and sagittal plane was equally often observed for the 1 st as well as for the 2 nd group visual handicaps. The most common postural type in the sagittal plane for the participants was kyphotic -lordotic posture.
