This study determined differences in spinal-pelvic kinematics sitting on (i) mat (ii) block and (iii) novel 10o forward inclined wedge (ButtaflyTM) in a samesubject repeated measures cross-over design in 60 healthy individuals (34 females). Repeated measures ANOVA revealed statistically significant differences between sitting conditions and lumbar and pelvic sagittal angles. Both, the inclined ...

Objectives: Most elderly nursing home residents who need wheelchairs are not being assessed individually to ensure proper prescription for safe and effective mobility. This study evaluated the use of a new screening tool, the Resident Ergonomic Assessment Profile for Seating (REAPS). Methods: This descriptive study design examined the reliability and validity of the REAPS in a Veterans nursing ...

Adaptive seating devices (ASDs) are used in the treatment of children with multiple handicaps. This longitudinal study evaluated, through direct observation and parent-guardian assessment, the behavioral changes seen with the use of ASDs and programming. Nineteen individuals with multiple handicaps and developmental disabilities, aged 1 to 6 years, participated as subjects. Data were collected ...

Validated injury criteria are essential when developing restraints for AIS 1 neck injuries that should protect occupants in different crash situations. Such criteria have been proposed and attempts have been made to validate/falsify these. However, no criterion has to date been fully validated. The objective of this study was to evaluate the influence of seat geometry and seating posture on NIC...

Pressure ulcers are a large problem in individuals who use a wheelchair for their mobility and have limited trunk stability and motor function. Because no relation between interface pressure and pressure ulcer development has been established and no clinical threshold for pressure ulcer development can be given, looking at the sitting behavior of nondisabled individuals is important. Nondisable...

Twenty subjects performed typing tasks on a desktop computer and touch-screen tablet in two chairs for an hour each, and the effects of chair, device, and their interactions on each dependent measure were recorded. Biomechanical measures of muscle force, spinal load, and posture were examined, while discomfort was measured via heart rate variability (HRV) and subjective reports. HRV was sensiti...

This study compared outcomes of wheelchair seating and positioning interventions provided by telerehabilitation (n=10) and face-to-face (n=20; 10 in each of two comparison groups, one urban and one rural). Comparison clients were matched to the telerehabilitation clients in age, diagnosis, and type of seating components received. Clients and referring therapists rated their satisfaction and ide...
