Chiropractic Management of a Patient With Thoracic Pain and a Stable Thoracic Aortic Aneurysm: A Case Report

Large abdominal aortic aneurysm presented with concomitant acute lumbar disc herniation - a case report

The purpose of this case report was to describe chiropractic management of acute lumbar disc herniation in a patient with a large abdominal aortic aneurysm. A 72-year-old male patient presented with low back pain and right lower leg numbness for 12 months. A review of full-spine X-ray and lumbar MRI revealed moderate spondylosis at L2-5, moderate lumbar scoliosis, and a 7.15 cm abdominal aortic aneurysm (AAA). Given the minimum 2-weeks of referral waiting time to receive treatment for AAA, the patient received chiropractic treatment with a hybrid rehabilitation to address the disc herniation causing severe physical disability. Through the treatments, the patient's pain was significantly alleviated with careful consideration of potential risk factors associated with AAA. In addition, the acute disc herniation was successfully managed by a series of chiropractic treatments before and after the operation for AAA. This case supports that low back pain in patients with AAA can be managed by manual therapy, in contrast to a widespread belief that manual therapy is contraindicated in AAA. More case reports of AAA patients with low back pain are warranted to assess the effectiveness and safety of manual therapy along with surgical treatment for AAA.

Spine adjusting instrument (Impulse®) attenuates nociception and modulates oxidative stress markers in the spinal cord and sciatic nerve of a rat model of neuropathic pain

OBJECTIVE

Oxidative stress plays an important role in neuropathic pain. Spinal manipulative therapy (SMT) can exert beneficial effects in pain outcomes in humans and animal models. SMT can also modulate oxidative stress markers in both humans and animals. We aimed to determine the effect of Impulse®-assisted SMT (ISMT) on nociception and oxidative stress biomarkers in the spinal cord and sciatic nerve of rats with neuropathic pain (NP).

METHODS

NP was induced by chronic constriction injury (CCI) of the sciatic nerve. Animals were randomly assigned to naive, sham (rats with sciatic nerve exposure but without ligatures) and CCI, with and without ISMT. ISMT was applied onto the skin area corresponding to the spinous process of L4-L5, 3 times/week, for 2 weeks. Mechanical threshold, latency to paw withdrawal to thermal stimulus and oxidative stress biomarkers in spinal cord and sciatic nerve were the main outcomes evaluated.

RESULTS

ISMT significantly increased mechanical threshold and withdrawal latency after CCI. In the spinal cord, ISMT prevented the increase of pro-oxidative superoxide anion generation and hydrogen peroxide levels. Lipid hydroperoxide levels both in the spinal cord and in the sciatic nerve were attenuated by ISMT. Total antioxidant capacity increased in the spinal cord and sciatic nerve of CCI rats with and without ISMT. CCI and ISMT did not significantly change the total thiol content of the spinal cord.

CONCLUSIONS

Our findings suggest reduced oxidative stress in the spinal cord and/or nerve may be an important mechanism underlying a therapeutic effect of SMT to manage NP non-pharmacologically.
