Abstract

fetched live from OpenAlex

Objective: This commentary aims to summarise the importance of the joint nervous system in maintaining joint homeostasis and the role of nerves in contributing to degenerative diseases such as osteoarthritis (OA). Methods: Pertinent scientific literature was evaluated and summarised to form the hypothesis that OA is a neurological disease. Results: Joint nerves regulate a constant blood supply to maintain joint homeostasis and sustain tissue health; however, in OA this neurovascular control system is compromised and joint tissue integrity declines. Similarly, a decrease in joint proprioceptors and nociceptors with age and during arthritis interferes with position sense and pain transmission so that the body is unable to correct abnormal loading and this alteration in joint biomechanics can lead to joint destruction. Finally, brain morphology and activity are altered in OA patients but can be rectified by total joint replacement. Conclusions: Joints possess a complex nervous system that controls multiple physiological functions such as tissue blood flow, position sense, and pain. Damage or dysfunction of the joint nervous system can affect joint health and promote degenerative diseases such as OA. Drugs that are used to treat neurological diseases such as epilepsy and depression have been found to be effective at ameliorating the symptoms of OA. Thus, in addition to age, obesity, joint instability, and sex, neuronal impairment could be considered an additional risk factor for the development and pathogenesis of OA.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
