Chiropractic Care for Spinal Whiplash Injuries


Chiropractic Care for Spinal Whiplash Injuries

By David BenEliyahu

Studies on the efficacy of chiropractic care for patients suffering with pain secondary to whiplash injury are appearing in the literature. In 1996, Woodward et al. published a study inInjury on the efficacy of chiropractic treatment of whiplash injuries.1 The authors of this study were from the Department of Orthopedic Surgery in Bristol, England.

In 1994, Gargan and Bannister published a paper on the recovery rate of patients with whiplash injuries and found that if patients were still symptomatic after three months, there was almost a 90% chance they would remain so.2 No conventional medical treatment has been shown to be effective in these established chronic whiplash injury patients.3,4 However, most DCs treating whiplash injury patients have empirically found high success rates in the recovery of these types of patients.

In the Woodward study, 93% of the 28 patients studied retrospectively were found to have a statistically significant improvement following chiropractic care.1 Chiropractic care in this study consisted of spinal manipulation, PNF and cryotherapy. Most of the 28 patients had prior treatment with NSAIDs, soft collars and physiotherapy. The average length of time before the patients began chiropractic care was 15.5 months post-MVA (range of 3-44 months).

This study clearly documented what most DCs experience in clinical practice: that chiropractic care is an effective modality for patients injured in a motor vehicle accident. Symptoms ranging from headaches to neck pain, back pain, interscapular pain and related extremity pain with parasthesias all respond to quality chiropractic care.

The literature has also suggested that cervical disc injuries are not uncommon after whiplash injury.5 In a study published on chiropractic care for disc herniations, I demonstrated that not only do patients improve clinically, repeat MRI imaging demonstrates decreased size or resolution of the disc herniation in many cases.6 Of the 28 patients studied and followed, several had post-MVA disc herniations that responded well to chiropractic care, with good clinical and anatomical outcome.6,7 In a recent retrospective study by Khan et al., published in theJournal of Orthopedic Medicine, on whiplash injured patients with respect to cervical pain and dysfunction, patients were stratified into groups based on degrees of good outcome to chiropractic care:8

Group I: Patients with neck pain only and restricted neck ROM. Patients had a “coat hangar” distribution of pain with no neurologic deficits; 72% had a good outcome.

Group II: Patients with neurological symptoms or signs and restricted spinal ROM. Patients had tingling, numbness and parasthesias in the extremity; 94% had a good outcome.

Group III: Patients had severe neck pain with full neck ROM and bizarre pain distributions in the extremities. These patients often described blackouts, nausea, vomiting, chest pain and visual dysfunction; 27% had a good outcome.

The results of this study showed that in group I, 36/50 patients (72%) responded well to chiropractic care: in group II, 30/32 patients (94%) responded well to chiropractic care; and in group III, only 3/11 cases (27%) responded well to chiropractic care. There was a statistically significant difference in outcomes between the three groups (p < .0001).

This study provides new evidence that chiropractic care is effective for whiplash injured patients. However, the study did not take into account those patients who also had back injuries, extremity injuries and TMJ injuries, and did not identify which patients had disc injuries, radiculopathy and concussive brain injury (most likely group III patients). In my experience, these types of patients respond better than 27% of the time with a more extensive model of chiropractic care, in conjunction with multidisciplinary providers.

These studies show what most DCs have already experienced that the doctor of chiropractic should be the primary care provider in these types of cases. It is my further opinion that in cases like the group III patients, care should be multidisciplinary so as to achieve the best possible outcome in difficult clinical cases.
