INTRODUCTION Seat belt use reduces the risk of injuries and fatalities among motor vehicle occupants in a crash, but belt use in rear seating positions is consistently lower than front seating positions. Knowledge is limited concerning factors associated with seat belt use among adult rear seat passengers. METHODS Data from the 2012 ConsumerStyles survey were used to calculate weighted percen...

This paper presents a gray box approach for identifying physical parameters of an electromechanical actuator based on frequency response data. A feedforward and Linear-Quadratic Regulator feedback controller was developed to control the EMCV actuator for soft seating. A repetitive learning controller was designed to enhance the control performance through cycleto-cycle iterations. Experimental ...

The clinician providing seating for patients who are unwell, who have poor functional ability or who are at risk of pressure sores, is faced with an increasing choice of products. Making the decision as to which product and associated features to choose can be a difficult task. This article describes the importance of suitable seating provision in patients who are at risk and outlines the Karom...

PURPOSE We reviewed research on the effect of adaptive seating on sitting posture/postural control in children with cerebral palsy. Second, we examined whether changes in postural control related to changes in other aspects of functioning. METHODS Electronic database/hand searches were undertaken to locate studies published in English. Reviewers screened studies for inclusion criteria, extrac...

We reviewed the initial post-operative radiographs of the Trident acetabulum and identified a problem with seating of the metal-backed ceramic liner. We identified 117 hips in 113 patients who had undergone primary total hip replacement using the Trident shell with a metal-backed alumina liner. Of these, 19 (16.4%) were noted to have incomplete seating of the liner, as judged by plain anteropos...

The Matrix seating system is an adaptable orthosis made of interlocking plastic components which can be shaped to fit the needs of the disabled. Twenty-five patients who had used this system for a minimum of 12 months have been assessed clinically. It was found to have several advantages over its rivals particularly in patient and guardian acceptance, versatility and on economic grounds. Howeve...

Abstract: We consider the solvability of a hybrid model for the vibration of a vertical slender structure mounted on an elastic seating. The slender structure is modeled as a Rayleigh beam and gravity is taken into account. The seating and foundation block are modeled as rigid bodies connected by elastic springs with damping mechanisms. We show how an existence result for a general linear vibra...
