PainSci summary of Nachemson 1992?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.

From the abstract: “Psychosocial factors, including insurance benefits, have been demonstrated to be more important than biomechanical workload not only for acute but also for chronic low back pain patients who are unable to work. Orthopedic surgeons must recognize this fact when contemplating operations for patients with ill-defined back syndromes. Rarely are diagnoses scientifically valid, nor is the effectiveness of surgery proven by acceptable clinical trials.”

original abstractAbstracts here may not perfectly match originals, for a variety of technical and practical reasons. Some abstacts are truncated for my purposes here, if they are particularly long-winded and unhelpful. I occasionally add clarifying notes. And I make some minor corrections.

Scientific scrutiny of the low back problem demonstrates its socioeconomic importance in most industrialized societies. Natural history studies reveal that the prognosis for the low back pain patient is excellent; for those with sciatica and painful spondylolisthesis it is good. It is even relatively good for those older patients with symptoms of spinal stenosis. Although today there is a better understanding of pain, the pathomechanism of low back pain is unknown. However, for patients with sciatica, spondylolisthesis, and spinal stenosis, physicians are beginning to get a better perception of what causes the pain. Psychosocial factors, including insurance benefits, have been demonstrated to be more important than biomechanical workload not only for acute but also for chronic low back pain patients who are unable to work. Orthopedic surgeons must recognize this fact when contemplating operations for patients with ill-defined back syndromes. Rarely are diagnoses scientifically valid, nor is the effectiveness of surgery proven by acceptable clinical trials.
