Everything is uncertain when it comes to whether spa therapy, such as mud packs or carbon dioxide baths are better than, erm nothing, in patients with RA according to a Cochrane review.
We thought uncertain made a pleasant change at least from insufficient evidence, but alas, there’s also that.
“Overall evidence is insufficient to show that balneotherapy is more effective than no treatment, that one type of bath is more effective than another or that one type of bath is more effective than mudpacks, exercise or relaxation therapy,” the review concludes.
