Key result
Positive lumbar discograms with concordant pain linked to increased heart rate versus negative discograms.
Why the study?
Lumbar discography is controversial due to its subjective nature, and heart rate changes have not been studied as an objective correlate of discography-induced pain.
Does heart rate response correlate with positive discography results in patients with low back pain?
Population
26 subjects with low back pain undergoing 75 lumbar discograms
Comparison
Positive discograms (concordant pain) vs negative discograms (nonconcordant or no pain)
Design
Prospective clinical data analysis
Follow-up
Immediate during procedure

May support heart rate monitoring during discography; leaves open diagnostic utility pending prospective validation.
Observational (n=26)
Does heart rate response correlate with positive discography results in patients with low back pain?
p-value: p=0.000002
Heart rate significantly increases during positive lumbar discography, suggesting it may serve as an objective physiological marker of concordant discogenic pain.
Stojanovic et al. (2007) conducted an observational in Low back pain (n=26). Concordant pain during lumbar discography vs. No pain or nonconcordant pain during discography was evaluated on Heart rate (HR) response during disc stimulation (p=0.000002). Positive lumbar discograms with concordant pain were associated with a statistically significant increase in heart rate (P=0.000002), whereas negative or nonconcordant discograms were not.
