“…In another study with adults with and without intellectual disability, Mauerberg-deCastro et al (2012) again found that the anchor system was efficient as an aid for postural tasks, reducing the path length of the COP when comparing pre-and post-practice without the anchors. The adults with and without disabilities improved their postural performance equally when using the anchors, in contrast to the pre-practice trial.…”

“…In two other studies that used the anchor system, various levels of task difficulty 3 in the postural task were tested in individuals with intellectual disability (Mauerberg-deCastro, Moraes, & Campbell, 2012;Mauerberg-deCastro et al, 2010). The primary rationale for testing these individuals was to demonstrate whether or not the use of the anchors required higher levels of cognitive processing.…”

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.

“…In that study, we suggested that this limitation in transfer effect could be the result of the walking task's low level of difficulty. Benefits of the anchors are less evident during the practice of simple postural tasks (e.g., standing with feet apart) as compared to tasks that challenged balance control (e.g., standing with one foot, with feet together, or with eyes closed) [10,17]. Our previous study [7] showed that tandem walking in a straight line on level ground was not challenging enough for the participants to exploit the additional haptic input provided by the anchors, although this task caused destabilization of their posture.…”

This study assessed the contribution of the "anchor system's" haptic information to balance control during walking at two levels of difficulty. Seventeen young adults and seventeen older adults performed 20 randomized trials of tandem walking in a straight line, on level ground and on a slightly-raised balance beam, both with and without the use of the anchors. The anchor consists of two flexible cables, whose ends participants hold in each hand, to which weights (125 g) are attached at the opposing ends, and which rest on the ground. As the participants walk, they pull on the cables, dragging the anchors. Spatiotemporal gait variables (step speed and single- and double-support duration) were processed using retro-reflective markers on anatomical sites. An accelerometer positioned in the cervical region registered trunk acceleration. Walking on the balance beam increased single- and double-support duration and reduced step speed in older adults, which suggests that this condition was more difficult than walking on the level ground. The anchors reduced trunk acceleration in the frontal plane, but the level of difficulty of the walking task showed no effect. Thus, varying the difficulty of the task had no influence on the way in which participants used the anchor system while tandem walking. The older adults exhibited more difficulty in walking on the balance beam as compared to the younger adults; however, the effect of the anchor system was similar in both groups.

“…Changes in body orientation relative to the support surface are detected by variations of pressure exerted on the skin by the anchor cable. 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 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.
