Tissue Loading Created During Spinal Manipulation in Comparison to Loading Created by Passive Spinal Movements

Chiro.Org Blog: Spinal manipulative therapy (SMT) creates health benefits for some while for others, no benefit or even adverse events. Understanding these differential responses is important to optimize patient care and safety. Toward this, characterizing how loads created by SMT relate to those created by typical motions is fundamental. Using robotic testing, it is now possible to make these comparisons to determine if SMT generates unique loading scenarios. In 12 porcine cadavers, SMT and passive motions were applied to the L3/L4 segment and the resulting kinematics tracked. Despite methodological differences between studies, SMT forces and loading rates fell below published injury values. […]

Outcomes Of Pregnant Patients With Low Back Pain Undergoing Chiropractic Treatment

Chiro.Org Blog: 52% of 115 recruited patients ‘improved’ at 1 week, 70% at 1 month, 85% at 3 months, 90% at 6 months and 88% at 1 year. Most pregnant patients undergoing chiropractic treatment reported clinically relevant improvement at all time points. No single variable was strongly predictive of ‘improvement’ in the logistic regression model. […]

The OUCH Randomized Controlled Trial of Adverse Events

Chiro.Org Blog: A substantial proportion of adverse events after chiropractic treatment may result from natural history variation and nonspecific effects. […]

Symptomatic Reactions, Clinical Outcomes and Patient Satisfaction Associated with Upper Cervical Chiropractic Care

Chiro.Org Blog: A total of 1,090 patients completed the study having 4,920 (4.5 per patient) office visits requiring 2,653 (2.4 per patient) upper cervical adjustments over 17 days. Three hundred thirty- eight (31.0%) patients had symptomatic reactions (SRs) meeting the accepted definition. Intense SR (NRS ≥8) occurred in 56 patients (5.1%). Outcome assessments were significantly improved for neck pain and disability, headache, mid-back pain, as well as lower back pain and disability (p <0.001) following care with a high level (mean = 9.1/10) of patient satisfaction. The 83 chiropractors administered >5 million career upper cervical adjustments without a reported incidence of serious adverse event. […]

Outcomes of Usual Chiropractic; Harm (OUCH) Randomised Controlled Trial of Adverse Events

Chiro.Org Blog: This was the first study to use a sham-controlled design to examine adverse events after chiropractic treatment. A substantial proportion of adverse events experienced during chiropractic care for spinal pain may be the result of natural symptom fluctuation or from nonspecific effects. Adverse events were common in both the usual chiropractic care and sham groups, but no important differences were seen between the groups and no serious adverse events were reported. […]
