Both forelimbs of rats were amputated and these rats were kept in the custom-made cages to keep prolonged and repeated upright posture. Changes of bone were observed in the lumbar vertebrae at three different time points after the surgery. ⋯ Prolonged upright posture induces cartilage end plate calcification and hypertrophy in rat lumbar spine.

Randomized Controlled Trial
The McKenzie method compared with manipulation when used adjunctive to information and advice in low back pain patients presenting with centralization or peripheralization: a randomized controlled trial.
Randomized controlled trial. ⋯ In patients with low back pain for more than 6 weeks presenting with centralization or peripheralization of symptoms, we found the McKenzie method to be slightly more effective than manipulation when used adjunctive to information and advice.
-
Cost-effectiveness analysis of a randomized plus observational cohort trial. ⋯ Comparative effectiveness evidence for clearly defined diagnostic groups from Spine Patient Outcomes Research Trial shows good value for surgery compared with nonoperative care over 4 years.
