Whiplash Injury Safety Moment S. Petmecky DWX Technology

Whiplash Injury Safety Moment S. Petmecky DWX Technology Planning Workshop July 27, 2000 What is Whiplash Injury? Definition: Whiplash is an acute injury of at least crushed

moderate intensity which causes a strain to the bones, muscles, nerves, tendons, and vertebral discs of the neck region. It is caused by a sudden, unexpected impact which jerks the head back and then forward causing the neck to snap out of alignment. DWX Technology Planning Workshop July 27, 2000 Where could it happen? 1) Traffic/stop light (traffic light disease) 2) End of traffic jam/queue 3) Sport (Boxing, Karate, Judo) 4) Roller coaster

DWX Technology Planning Workshop July 27, 2000 What are the symptoms? Symptoms are: headaches/migraines, stiffness, neck pain, dizziness (nausea/vomiting), problems thinking or remembering, numbness and tingling (arms, face, shoulders), jaw pain, low back pain, hip pain, impaired vision DWX Technology Planning Workshop July 27, 2000 What is a potential outcome? Before After

Note misalignment of vertebral discs after suffering from a whiplash injury. DWX Technology Planning Workshop July 27, 2000 What happens to the driver? (I) What happens during a rear end collision if - head restraint - seat position - seat belt height are not adjusted correctly? 1) Body moves up depending on angle of backrest and position of seat belt adjustor.. 2) ..head jerks back..

3) ..pushing the head restraint down DWX Technology Planning Workshop July 27, 2000 What are the facts? Facts: - even low speed accidents can cause significant injuries depending on where and how hard your car got hit, your position in the car, the position of your head, type of seat, position of the headrest, your pre-accident medical condition, and other things - only 12% of persons who suffer from whiplash are symptom-free after 10 years - Saab was the first to introduce an active protection system (SAHR); Volvos Whiplash Protection Seating System reduces acceleration forces on the neck by up to 50 % - A study by Young et al. (2005) showed that 93% of all head restraints

observed were sub-optimally positioned A L Young, B T Ragel, E Su, C N Mann, E H Frank: Assessing automobile head restraint positioning in Portland, Oregon; Injury Prevention 2005; 11: 97-101. DWX Technology Planning Workshop July 27, 2000 How can it be prevented? Adjust your head restraint Teminology 6 cm 7 cm 1) Ensure that the top of the head restraint is as high as the top of your head.

2) Position the head restraint as close to the rear of your head as possible.

Adjust your seat position First, the driver's back should be flat against the back of the seat with the buttocks squarely tucked into the corner created at the intersection of the seat back

and bottom. The underside of the legs should be in contact with the seat bottom. The purpose of this position is to provide as much surface contact between the driver's body and the seat. This has safety benefits as well as providing the driver with the most tactile feedback as possible DWX Technology Planning Workshop July 27, 2000 Second is the arm position. The arms when fully extended should allow the wrists to rest at the top of the steering wheel. This allows the arms

to be slightly bent at the elbow when fully extended for a turn. The purpose of this position is to prevent the arms from being overextended during turns (the shoulders should not need to lift from the seat back even to do a full arm crossover). Overextending the arms will cause them to tire quickly, and will cause the driver to lose sensitivity to the vibrations in the steering wheel Third is the leg position. When any of the pedals are fully depressed with the ball of the foot on the pedal (not the

toes), the leg should still be bent at the knee. This is to prevent overextension as described for the arms. Be sure that the knees are not against the underdash or steering column. In fact, there should be several inches room to prevent injury in event of a collision.

3) Check seat belt adjustor position 4) Leave plenty of space (escape route) if you are the last car in a traffic jam closely observe oncoming traffic in rear view mirror 5) Look up safety ratings before buying your next new or used car DWX Technology Planning Workshop July 27, 2000
