The Effects of Lower Right Limb Orthopedic Immobilization on Driving Performance

05:36 EDT 17th September 2014 | BioPortfolio


Abstract Background: Effects of orthopedic immobilizations of the lower right limb on driving performances are unknown. Therefore, clinicians and legislators cannot put forth recommendations for road safety for patients requiring such immobilizations. The objective of the present study was to evaluate the effects of different orthopedic immobilizations on braking performances in simulated driving conditions.

Methods: The braking performances of 48 healthy volunteers were evaluated under 3 conditions: wearing their running shoes, and 2 types of orthopedic immobilizations of the lower right limb, a walking cast and an Aircast walker. A computerized driving simulator was used to measure the maximum force applied on the brake pedal during braking, the braking reaction time and the total braking time during emergency braking with and without a distracter.

Medical and Biotech [MESH] Definitions

The effect of environmental or physiological factors on the driver and driving ability. Included are driving fatigue, and the effect of drugs, disease, and physical disabilities on driving.

Government required written and driving test given to individuals prior to obtaining an operator's license.

Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow.

A calcium salt that is used for a variety of purposes including: building materials, as a desiccant, in dentistry as an impression material, cast, or die, and in medicine for immobilizing casts and as a tablet excipient. It exists in various forms and states of hydration. Plaster of Paris is a mixture of powdered and heat-treated gypsum.

Dressings made of fiberglass, plastic, or bandage impregnated with plaster of paris used for immobilization of various parts of the body in cases of fractures, dislocations, and infected wounds. In comparison with plaster casts, casts made of fiberglass or plastic are lightweight, radiolucent, able to withstand moisture, and less rigid.
