Toque: qual o uso atual pelo enfermeiro?

Este trabalho tem como objetivo verificar o uso do toque pelo enfermeiro, na categoria proposta por LE MAY (1986), assim como sua percepção de quando e por que ele o utiliza. Foram entrevistados, para tanto, 37 enfermeiros (20 docentes, 16 assistenciais e 1 aprimorando), em setembro de 1995, na capital e interior do Estado de São Paulo, constatando-se que a maioria da amostra coletada fez menção ao toque de forma expressiva, referindo utilizá-lo principalmente para demonstrar empatia e segurança em momentos que percebe a expressão das emoções do paciente.

Postural control as a function of self- and object-motion perception

The goals of this study were to examine the visual information influence on body sway as a function of self- and object-motion perception and visual information quality. Participants that were aware (object-motion) and unaware (self-motion) of the movement of a moving room were asked to stand upright at five different distances from its frontal wall. The visual information effect on body sway decreased when participants were aware about the sensory manipulation. Moreover, while the visual influence on body sway decreased as the distance increased in the self-motion perception, no effects were observed in the object-motion mode. The overall results indicate that postural control system functioning can be altered by prior knowledge, and adaptation due to changes in sensory quality seem to occur in the self- but not in the object-motion perception mode.

Perception-action coupling in infants with down syndrome: Effects of experience and practice

This study examined the effects of experience and practice on the coupling between visual information and trunk sway in infants with Down syndrome (DS). Five experienced and five novice sitters were exposed to a moving room, which was oscillated at 0.2 and 0.5 Hz. Infants remained in a sitting position and data were collected on the first, fourth, and seventh days. On the first day, experienced sitters were more influenced by room oscillation than were novices. On the following days, however, the influence of room oscillation decreased for experienced but increased for novice sitters. These results suggest that the relationship between sensory information and motor action in infants with DS can be changed with experience and practice.
