While cervical disc pathology can unquestionably produce radiculopathy, many patients presenting with arm pain, paresthesia or perceived weakness do not exhibit the clinical behavior of true nerve-root compromise. In these cases, failure to differentiate the primary pain generator may lead to unnecessary spinal injections, nerve ablation procedures or surgical consultation despite limited likelihood of benefit.
Not in Your Head
According to a recent study in Italy, spinal manipulation reduced the total pain index (TPI) of cervicogenic headache, and the drug consumption index (DCI) of patients on analgesic or anti-inflammatory medication. The eight-week study showed spinal manipulation effective during the care period (weeks 1-4), and during the follow-up period (weeks 5-8).
