“…The removal of the anchor system resulted in better performance relative to the initial trial. This was contrary to a study by Freitas et al (2013), who did not confirm these findings for older adults. Their results showed that performing the balance task (i.e., baseline task without the anchor system) immediately after the blocks of practice that used the anchor system resulted in no effect in their postural control parameters; however an improvement appeared 24 h later.…”

Several studies have emphasized the contribution of haptic input that results from the use of rigid and non-rigid tools to the postural control system. Experimental protocols such as the light touch and the anchor system are based on individuals' haptic exploration of the environment through direct tactile-kinesthetic contact, or indirectly through rigid or flexible tools that are attached to the body. In this article, we introduce the main findings of humans' haptic use of non-rigid tools during postural control tasks. We illustrate the effects of an anchor system paradigm on the maintenance of stability via haptic information. Haptic anchoring includes the handling of flexible cables that are attached to loads that are in contact with a surface. We include results of studies about haptic information gathered during the holding of a walking dog's leash. Studies that used the anchor system demonstrated its effectiveness in reducing body sway in several groups, including young adults, children, older individuals, and intellectually disabled individuals. We discuss several experimental designs and intervention protocols in order to illustrate how haptic anchoring could prompt functional plasticity.

“…Moreover, using the strap did not affect the anchor system contribution to reduce body sway. These results, except for the anchor on the shoulder, are in accordance with our previous studies, in which we showed that the anchor system reduced older adults' body sway while maintaining an upright posture 3,15 and during tandem gait 16 . This study's results partially confirm its hypothesis, for fastening the anchor on the shoulder did not reduce body sway.…”

“…Adults with intellectual deficiency benefited from additional haptic information provided by the anchor system, and reduced body sway 13,14 . Older adults, likewise, have reduced body sway with the anchor system 3,15,16 . The anchor system advantages are noticed not only during its use 3,16 , but also and more importantly after its use 15 , making it a tool with potential for clinical and training application.…”

| The anchor system is a nonrigid tool that provides additional haptic information. It consists of two malleable cables with 125g loads resting on the floor, whereas the hands hold the other end of the cable (hand anchor). If we consider that light touch of different parts of the body reduces body sway, it is also possible that the use of the anchor system on different parts of the body might be effective. Therefore, this study aimed at investigating the effect of using the anchor system on different parts of the body on older adults' body sway. Thirty older adults The improvement observed with the use of anchors does not seem to be related to the amount of tactile receptors at the point of contact with the anchor cables.

“…Estudos com o sistema âncora revelaram melhora no controle postural em indivíduos idosos, reduzindo a oscilação corporal durante a manutenção da postura ereta semi estática 5,8,10 . É importante destacar, entretanto, que nos estudos prévios com o sistema âncora [3][4][5][6][7][8]10 , o modelo experimental predominante das tarefas hápticas envolvia os participantes segurarem as âncoras bilateralmente, o que evidencia uma referencia simétrica da ancoragem.…”

“…Os diferentes componentes desses três sistemas podem ser afetados por patologias específi cas ou por perdas progressivas decorrentes do próprio processo de envelhecimento. Assim, é importante para profi ssionais da área da saúde buscar novas estratégias de intervenção que permitam uma melhora da função postural e, consequentemente, redução das instabilidades posturais e o medo de cair em idosos.Desde 2004, uma nova ferramenta chamada sistema âncora vem sendo investigada como uma promissora contribuição para redução da instabilidade postural [3][4][5][6][7][8] . A manipulação do sistema âncora requer dos indivíduos segurarem em cada mão um cabo de propriedade fl exível com uma leve massa anexada ao fi nal do cabo (i.e., âncora) em contado com o chão.…”
