MVA Neck Pain: Is the facet joint the ‘driver’ of my patient’s symptoms?

Everyday, physical therapists are striving to be better at clinical decision making. But in patients with chronic neck pain, it can be challenging for therapists to select the right treatment at the correct time for optimum outcomes for the patient. Motor vehicle accident whiplash-associated disorders or chronic neck pain from other ‘traumas’ can be evaluated by selected manual techniques and evidence based questionnaires to select the patients best suited for consideration of a cervical facet injection (cRFN or cervical radiofrequency neurotomy). Earlier studies, have shown that paraspinal tenderness, positive mechanical exam of spine segment can be combined with > 50% relief of familiar pain symptoms with a medial branch block injection to the ‘culprit’ segment, to be significant indicators of a positive response to a subsequent cRFN. Smith et al. 2016 has now established that in WAD Grade II patients, low scores on the pain catastrophization scale and neck disability scale, show a higher likelihood of success to the cRFN versus those patients who had higher pain focus, a tendency to catastrophize their condition and rated their level of function lower.

Also, in 2015, these same investigators found that WAD Grade II patients symptoms were not solely maintained by changes in the central nervous system (central sensitization only), but central sensitization was influenced by peripheral nociception (ie. Pain coming from other, peripheral sources such as the zygopophyseal joint).

So consider applying these clinical subjective and objective tests to help you determine if the facet joint is the ‘driver’ of your patient’s neck pain symptoms. Discuss these findings with the patient and a physician skilled at applying cRFN injections, to determine if proceeding to a segmental injection will give your patient the best outcomes possible.
