“…Some researchers have specifically investigated the haptic system's functional role on postural control (Riley, Stoffregen, Grocki & Turvey, 1999;Carello, Silva, Kinsella-Shaw & Turvey, 2008;Holden, Ventura & Lackner, 1994). The current study explores the contribution of haptic perception to the basic function of postural control through individuals' manual use of nonrigid tools, during their maintenance of the upright stance.…”

We tested the short-term effects of a nonrigid tool, identified as an "anchor system" (e.g., ropes attached to varying weights resting on the floor), on the postural stabilization of blindfolded adults with and without intellectual disabilities (ID). Participants held a pair of anchors-one in each hand, under three weight conditions (250 g, 500 g and 1,000 g), while they performed a restricted balance task (standing for 30 s on a balance beam placed on top of a force platform). These conditions were called anchor practice trials. Before and after the practice trials, a condition without anchors was tested. Control practice groups, who practiced blocks of trials without anchors, included individuals with and without ID. The anchor system improved subjects' balance during the standing task, for both groups. For the control groups, the performance of successive trials in the condition without the anchor system showed no improvement in postural stability. The individuals with intellectual disability, as well as their peers without ID, used the haptic cues of nonrigid tools (i.e., the anchor system) to stabilize their posture, and the short-term stabilizing effects appeared to result from their previous use of the anchor system.

“…While the individual elements of an experience with motion change (e.g., distance to targets, flow of visual field, etc. ), the lawful properties of the mass distribution of muscles and objects at hand (e.g., inertia, moments of inertia, and vibratory resonance) remain perceptually constant or invariant (Carello, Silva, Kinsella-Shaw, & Turvey, 2008;Carello & Turvey, 2004;Michaels & Carello, 1981). This detection of invariants is possible as long as the environment affords 1 possibilities for an action or behavior.…”

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 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). The haptic system's effect on postural control later gained the interest of researchers in the action-perception area (Burton, 1993;Carello, Silva, Kinsella-Shaw, & Turvey, 2008;Holden, Ventura, & Lackner, 1994;Lackner & DiZio, 2005;Rabin, DiZio, & Lackner, 2006;Rabin, DiZio, Ventura, & Lackner, 2008). Individuals' use of tools for postural orientation during the maintenance of an upright position, or during the execution of movements such as the handling of objects, can provide us with excellent examples of how humans detect information by exploring different textures and dimensions indirectly, rather than via "biological detectors" such as hands or fingertips.…”

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...
