All rights reserved. Most of the injuries happen in C-5 and C While the time associated with a specific collision will vary, the following provides an example of the occupant and seat interaction sequence for a collision lasting approximately milliseconds. Diagnosis occurs through a patient history, head and neck examination, X-rays to rule out bone fractures and may involve the use of medical imaging to determine if there are other injuries.
The focus of preventive measures to date has been on the design of car seats, primarily through the introduction of head restraints, often called headrests. This approach is potentially problematic given the underlying assumption that purely mechanical factors cause whiplash injuries — an unproven theory. Improvements in the geometry of car seats through better design and energy absorption could offer additional benefits.
Active devices move the body in a crash in order to shift the loads on the car seat. As a result, different types of head restraints have been developed by various manufactures to protect their occupants from whiplash. The most effective head restraint must allow a backset motion of less than 60 mm to prevent the hyperextension of the neck during impact. Adjustable head restraint — refers to a head restraint that is capable of being positioned to fit the morphology of the seated occupant.
Automatically adjusting head restraint — refers to a head restraint that automatically adjusts the position of the head restraint when the seat position is adjusted. A major issue in whiplash prevention is the lack of proper adjustment of the seat safety system by both drivers and passengers. Studies have shown that a well designed and adjusted head restraint could prevent potentially injurious head-neck kinematics in rear-end collisions by limiting the differential movement of the head and torso.
The primary function of a head restraint is to minimize the relative rearward movement of the head and neck during rear impact. More studies by manufacturers and automobile safety organizations are currently undergoing to examine the best ways to reduce head and torso injuries during a rear-end impact with different geometries of the head restraint and seat-back systems. In most passenger vehicles where manually adjustable head restraints are fitted, proper use requires sufficient knowledge and awareness by occupants.
When driving, the height of the head restraint is critical in influencing injury risk. A restraint should be at least as high as the head's center of gravity, or about 9 centimeters 3. The backset, or distance behind the head, should be as small as possible. Backsets of more than 10 centimeters about 4 inches have been associated with increased symptoms of neck injury in crashes.
In addition, there should be minimal distance between the back of head and the point where it first meets the restraint. Due to low public awareness of the consequence of incorrect positioning of head restraints, some passenger vehicle manufactures have designed and implemented a range of devices into their models to protect their occupants. Some current systems are:. The Insurance Institute for Highway Safety IIHS and other testing centers around the world have been involved in testing the effectiveness of head restraint and seat systems in laboratory conditions to assess their ability to prevent or mitigate whiplash injuries.
Various organisations exist which list such vehicles. Rehabilitation e.

The main purpose with early rehabilitation is to reduce the risk for development of Whiplash syndrome. Early rehabilitation for whiplash depends on the grade category. It can be categorized as grade 0 being no pain to grade 4 with a cervical bone fracture or dislocation. Grade 4 obviously needs admission to hospital while grade can be managed as outpatients. The symptoms from the potential injury to the cervical spine may be debilitating, and pain was reported to be one of the biggest stressor events experienced in daily living, so it is important to begin rehabilitation immediately to prevent future pain.
Furthermore, Schnabel and colleagues stated that the soft collar is not a suitable medium for rehabilitation, and the best way of recovery is to include an active rehabilitation program that includes physical therapy exercises and postural modifications. Another study found patients who participated in active therapy shortly after injury increased mobilization of the neck with significantly less pain within four weeks when compared to patients using a cervical collar.
Basic information is also given to teach the patient that exercises as instructed will not cause any damage to their neck. These exercises are done at home or under the care of a health professional. When beginning a rehabilitation regimen, it's important to begin with slow movements which include cervical rotation until pain threshold three to five times per day, flexion and extension of the shoulder joint by moving the arms up and down two to three times, and combining shoulder raises while inhaling and releasing the shoulder raise while exhaling.
Soderlund and colleagues also recommend that these exercises should be done every day until pain starts to dissipate. Patients who entered a rehabilitation program said they were able to control their pain, they continued to use strategies that were taught to them, and were able to go back to their daily activities. Medications According to the recommendations made by the Quebec Task Force, treatment for individuals with whiplash associated disorders grade 1—3 may include non-narcotic analgesics. Non-steroidal anti-inflammatory drugs may also be prescribed in the case of WAD 2 and WAD 3, but their use should be limited to a maximum of three weeks.

The consequences of whiplash range from mild pain for a few days which is the case for most people , to severe disability. A recent review concluded that although there are contradictions in the literature, overall there is moderate evidence that TMD can occasionally follow whiplash injury, and that the incidence of this occurrence is low to moderate. Whiplash is the term commonly used to describe hyperflexion and hyperextension, and is one of the most common nonfatal car crash injuries. More than one million whiplash injuries occur each year due to car crashes.
