A total of 283 wheelchair-seated bus riders responded to a 35-item Web-based survey investigating their experiences on public, fixed-route buses. The survey addressed the use of wheelchair tiedowns and occupant restraint systems (WTORS), the attitudes and behaviors of wheelchair users toward the use of this equipment, and the transit experience.

The Americans with Disabilities Act (ADA) has led to an increased number of wheelchair users seeking transportation services. Many of these individuals are unable to transfer to a vehicle and are instead required to travel seated in their wheelchairs. Unfortunately, wheelchairs are not typically designed with the same occupant protection features as motor(More)
BACKGROUND Short-distance falls, such as from a bed, are often falsely reported scenarios in child abuse. In attempting to differentiate between abusive and nonabusive injury, knowledge of factors that affect injury risk in falls could prove useful. OBJECTIVES To assess the biomechanics associated with simulated short-distance falls in children (one fall(More)
OBJECTIVE The objective of the work was to develop an estimate of the risk of death resulting from short falls of <1.5 m in vertical height, affecting infants and young children between birth and the fifth birthday. METHODS A review of published materials, including 5 book chapters, 2 medical society statements, 7 major literature reviews, 3 public injury(More)
OBJECTIVE The objectives of our study were to assess biomechanics associated with feet-first free falls in 3-year-old children and to investigate the influence of impact surface type and fall height on key biomechanical measures associated with injury risk. METHODS Repeatable feet-first free fall experiments were conducted in a laboratory mock-up(More)
OBJECTIVE The classic metaphyseal lesion is highly associated with abuse in infants. Classic metaphyseal lesions, also referred to as corner or bucket-handle fractures, are fractures through the metaphyseal region of the long bones near the growth plate. Knowledge of the biomechanics and mechanisms necessary to produce a classic metaphyseal lesion may(More)
We compared differences in isometric strength between older adults who have undergone elective unilateral total hip arthroplasty (THA) and completed rehabilitation with a population of community-dwelling older adults who have not had THA. The study was a cross-sectional design, and 22 unilateral THA subjects and 38 community-dwelling older adults(More)
BACKGROUND Stair falls are common among young children and are also common false histories in cases of child abuse. When a child presents with a femur fracture and a stair-fall history, a judgment of plausibility must be made. A lack of objective injury and biomechanical data makes plausibility determination more difficult. Our objective was to characterize(More)
OBJECTIVE To evaluate differences in isokinetic hip flexion, extension, and abduction muscle performance of operated vs. nonoperated hips in older adults who have undergone elective, unilateral, total hip replacement (THR) surgery and completed rehabilitation. DESIGN Quasi-experimental study using a nonequivalent posttest-only control group design,(More)
