Face-to-face interaction between infants and their caregivers is a mainstay of developmental research. However, common laboratory paradigms for studying dyadic interaction oversimplify the act of looking at the partner’s face by seating infants and caregivers face to face in stationary positions. In less constrained conditions when both partners are freely mobile, infants and caregivers must mo...

The aim of the present study was to perform a comparative biomechanical analysis of four antidecubitus wheelchair cushions. Thirty wheelchair users were considered divided into three groups: paraplegic subjects (with no cutaneous sensation), neurologic subjects (with intact cutaneous sensation), and elderly subjects. The biomechanical evaluation was performed using a piezoresistive sensor matri...

For many severely handicapped children requiring external trunk support there is probably no better solution than to provide custom moulded seating. This will improve the patient's posture, reduce the occurrence of pressure sores and facilitate such activities as feeding. However, if large numbers of patients are to be supplied with this type of equipment, it is important that it should be manu...

BACKGROUND Postural asymmetries with seating problems are common in adults with cerebral palsy. AIMS To analyse the prevalence of asymmetrical limited hip flexion (<90°) in adults with CP, and to evaluate the association between asymmetrical limited hip flexion and postural asymmetries in the sitting position. METHODS AND PROCEDURES Cross-sectional data of 714 adults with CP, 16-73 years, G...

BACKGROUND Back pain is a common complication of wheelchair-bound elderly people. Seating system is a key factor that influences spinal curvature, back muscle activation, interface pressure, and comfortability. A seating system can maintain lumbar lordosis, lower back muscle activity, and decrease ischial tuberosities pressure, which reduces spinal load and directly influences sitting comfort. ...
