According to Betteridge's law of headlines, the answer to the titles question is: NO!
The study found MICROSCOPIC effect sizes for the contribution of psychological factors in the persistence of shoulder pain!

First phase 3 trial for the novel non-opioid drug Suzetrigine. It’s not placebo controlled and aimed to test the safety profile of the drug. I am not sure wheter this could be considered “well-tolerated” and “generally safe”

It just means that the mode of activation is not nociceptive nor neuropathic. Unfortunately, the term nociplastic pain has been hijacked by those with vested interests to sell and promote psychological treatments for those with “non structural pain. Do not cooperate with this trend!

This activation can occur due to three mechanisms: nociceptive, neuropathic and nociplastic. It is now known that activation of nociception can occur independently and without observed tissue damage (nociplastic). This does not make nociplastic “non structural pain”

There is no such thing as “STRUCTURAL PAIN” and “non structural pain” etc. The plethora of unpleasant sensory experiences we humans use the word “pain” to describe them, are all the consequences of activation of our specialized appartus of nociception.

It should be obligatory for every med/life sci grad student to learn formal logic & reasoning. Too many published papers are poorly argued and make basic inferential errors. This small change would dramatically improve science

⭐️Surgery should be considered if leg pain and decreased walking distance are the main clinical features that disturb and affect the patient.

⭐️Eventually, at one year follow-up, both groups equalized in their outcomes,but the surgery group improved faster.

⭐️Functional tests are good at reflecting the subjective self assessment of patients with Spinal Stenosis and can be used for shared decision making.

What you can learn from the study:

⭐️ Leg pain and the decreased ability to walk are the main features that led those who opted for surgery.

⭐️Contrary to the vilification trend of lumbar surgery in healthcare, those with leg pain improved significantly faster than the wait and see group.

Instead of talking about the predatory nature of MDPI journals, can we talk about how UGLY their formatting is? It’s literally hurting my eyes reading their papers online and PDFs 😣

I don’t think its a prank. I could be wrong though. The Scand J Pain has never published pranks or comic editions like the traditional BMJ Christmas issue.

Finland Publication Forum will downgrade hundreds of Frontiers and MDPI journals A committee of scholars in Finland has decided to downgrade 271 journals from Frontiers and MDPI in their quality rating system, in a move that may discourage researchers from submitting manuscript…

Finalnd downgraded many MDPI and Frontiers journals in their quality grading. Good call for MDPI. As for Frontiers I am not really sure but tend to say its also a good call.
