Does biofeedback improve postural control recovery from multi-axis discrete perturbations?
The results show that among the displays evaluated in this study, no one tactor column configuration was optimal for standing tasks involving discrete surface perturbations. Feedback produced larger effects on body tilt versus center of pressure parameters. Furthermore, the subjects' performance worsened when erroneous feedback was provided, suggesting that vibrotactile stimulation applied to the torso is actively processed and acted upon rather than being responsible for simply triggering a stiffening response.
The results suggest that the experience of maltreatment has a negative impact on children's developing interpersonal skills above and beyond the influence of factors associated with low socioeconomic status and other environmental stressors.
