OBJECTIVE Although several previous studies have evaluated horizontal head restraint backset distances, few studies have evaluated them during driving. The purpose of this study was to measure this backset during routine automobile driving and to specifically evaluate the backset during individual driving tasks such as turning, stopping, starting, and lane changes. METHODS Fourteen subjects d...

introduction: shin splint is one of the common injuries in most athletes. although the relationship between abnormal foot posture and shin splint has been reported previously but, the relation between foot posture and shin splint has not been well documented. the aim of this study was to explore the relationship between foot postures in basketball players and the history of shin splint. materia...

Distracted driving is one of the main causes road crashes. Therefore, effective distinguishing distracted behaviour and its category key to reducing incidence To identify accurately effectively, this paper uses head posture as a relevant variable realizes classification based on literature investigation. A discrimination algorithm facial feature triangle proposed. In proposed algorithm, Bayesia...

The whole body vibration from the seat and foot board was measured during ten years from 11 different snowmobiles to evaluate the exposure and the need for technical improvements. In a questionnaire more than half of the drivers had back pains but only a few of them considered the whole body vibration as a health hazard. However in the literature there is often comments on spinal injuries relat...

This paper presents a time invariant kinematic motion controller for wheeled mobile robots. Actuator capability, mechanical design, and traction forces governed by terrain features provide velocity and curvature limitations that are used in the design of the controller. A novel path manifold that considers curvature limitations is introduced to provide a desired path shape and convergence to th...

A new car seat design, which allows the back part of the seat (BPS) to lower down while a protruded cushion supports the lumbar spine, was quantitatively tested to determine its effectiveness and potentials in reducing whole-body vibration (WBV) and musculoskeletal disorders in automobile drivers. Nine subjects were tested to drive with the seat in: 1) the conventional seating arrangement (Norm...

The aim of this study was to examine the effects of the sitting posture on the lower limb venous flow and to explore the beneficial effects of neuromuscular electrical stimulation (NMES) and an ottoman-type seat on the venous flow. Healthy adult volunteers without a history of lower limb surgery or thromboembolism were recruited, and the flow velocity, cross-sectional area, and flow volume of t...

Postural synergies describe characteristic patterns of actuation in human hands arising from biomechanical constraints, physical tendon coupling, and neurological control schemes. Often, a small number of synergies contain much of the information required to describe an entire human hand posture, with 80% or more of the total information encoded in only two component values. Synergies have comm...

the fear of driving can be severe enough to be considered a phobia. it is often great enough that people will avoid driving at all costs and instead find someone to drive them or use public transportation, regardless of how inconvenient or expensive. this fear will cause many to avoid driving, create excuses to not drive, or even refuse to get a driver's license for years. the aim of this ...
