Abstract
Thumb carpometacarpal (CMC) arthropathy pain is treated using carbonated water—a commercially available beverage. The right hand (affected side) was bathed once daily in carbonated beverage water (37°C) for 20 min. Prior to treatment, the visual analogue scale score of pain was 73 mm; 1 week after the treatment, it was 0 mm. Commercial carbonated water immersion was effective for thumb CMC arthropathy pain. Commercial carbonated water is inexpensive and easy to obtain, making it suitable for home carbonation therapy.

Blood flow to the capillary network is regulated by the alternating contraction and relaxation of the anterior capillary sphincter.
With a closed anterior capillary sphincter, massage or bathing to promote blood flow is unlikely to eliminate inflammatory chemical mediators. In a carbonated water bath, the anterior capillary sphincter muscles relax in all areas where percutaneous CO2 reaches, thus causing smooth muscle relaxation. Therefore, metabolites and inflammatory substances can be efficiently removed, and excellent muscle fatigue recovery and pain relief can be expected.
Result
Prior to treatment, the visual analogue scale score was 73 mm;
1 week after the treatment, it was 0 mm. Within 2 weeks, the treatment was completed, and the
patient experienced no pain even after 3 months of stopping the treatment.
Conclusion
Our study concluded that immersion of the affected hand in commercial beverage carbonated water
once a day for 20 min is effective in treating pain caused by thumb CMC osteoarthritis. The high concentration of CO2 easily reaches the inflamed area in osteoarthritis of the thumb, and the high CO2 concentration in commercial beverage carbonated water has a high flush-out effect on pain-related substances and is considered to have an excellent analgesic effect. Commercial carbonated water is inexpensive and easy to obtain, making it suitable for home carbonation therapy if the treated area is small. This study is a single case, and a randomized controlled trial is needed to substantiate this finding.
