Whiplash
is a common injury that is often ignored or improperly treated due to a lack of
understanding of the condition. Common whiplash symptoms include (but are not
limited to) neck pain/stiffness, headache, shoulder pain and stiffness,
dizziness, fatigue, jaw pain (TMJ symptoms), arm pain, numbness and/or
weakness, visual disturbances, ringing in the ears (tinnitis), and back pain.
In more severe cases, symptoms may include depression, anxiety, anger,
frustration, stress, drug dependency, post-traumatic stress, sleep disturbance,
sick leave, and lost productivity. Traumatic brain injury symptoms can include
difficulty formulating thought, losing one’s place in conversation, fatigue,
and “mental fog.” If litigation is involved, it can complicate the situation as
well. While most people involved in car crashes recover quickly, some continue
to experience symptoms that can last for years after the incident, and chronic
pain can have devastating effects on an individual and his/her family.
A
whiplash injury occurs as a result of a “crack the whip” mechanism that occurs
very fast and before the muscles have time to react (within 300 milliseconds,
which is too fast to voluntarily contract our muscles). About half-way through
this process, the lower cervical spine extends while the upper half flexes
resulting in significant pressure on the joint capsules in the lower half and
the disks in the upper half of the neck. Recently, an interesting study found
that there might a way to “trick” the neck muscles so they relax prior to the
crash, thus reducing the amount of pressure exerted on the neck structures and
potentially reduce the amount of tissue injury. A rear-end collision typically
results in neck muscle contractions from a combination of postural and startle
responses. Using surface EMG (electromyography) to measures muscle activity,
researchers found that the superficial muscle tightness of the neck could be
attenuated (decreased) by a loud tone (105dB) 250 milliseconds BEFORE impact.
Then, they investigated whether the deep cervical spine stabilizing,
involuntary muscles (specifically the multifidus) would respond similarly to a
loud tone. (This is important because these muscles attach directly to the
small facet joints located in the back of the spine and have the potential to
increase the strain in the joint capsules during a crash and contribute to the
whiplash injury.) The researchers subjected twelve study participants to
simulated whiplash situations both with and without a loud tone. Their results
suggest that a loud pre-impact tone may reduce the strain in the cervical spine
facet joint capsules, which in turn may reduce the amount of tissue injury
during a rear-end collision. These findings are exciting as the degree of
injury may be reduced from using this tone prior to an impact.
Early
range-of-motion types of care and exercises appear to result in better outcomes
than the use of a cervical collar and rest. Similarly, manual therapies
including early manipulation, mobilization, traction, and soft tissue therapies
have also been demonstrated to produce better outcomes for whiplash patients.
Chiropractic offers these treatment approaches to whiplash patients more
frequently when compared with other healthcare professions. We also include
patient education and advice on posture, proper bending, lifting, pulling and
pushing methods, the use of ice over heat (especially initially), and many
self-care, home-based treatment approaches. Exercises often include
range-of-motion/stretching, cervical curve retraining, strengthening,
stabilization exercises, and balance exercises. If dizziness is present, we can
show you special exercises to help manage it. An emphasis of transitioning the
patient to these active, self-managing approaches is truly appreciated by our
patients!
