FAQ: Stanford Study on Pulsed Shortwave Therapy for Thumb Arthritis Pain Relief

What is the main finding of the Stanford University study?

The study found that pulsed shortwave therapy (PSWT) provides sustained pain relief in adults with thumb carpometacarpal joint osteoarthritis, with the PSWT group maintaining pain relief even after device use was discontinued.

Why is this research significant for people with thumb arthritis?

This research is significant because thumb arthritis affects 4-7 million U.S. adults and makes everyday tasks difficult, and PSWT offers a safe, drug-free treatment option that can be used at home, potentially changing how this widespread condition is treated.

How was the clinical trial conducted?

The double-blind, randomized controlled trial involved 61 adults with thumb CMC osteoarthritis who used either an active PSWT device or an identical-appearing sham device for approximately eight hours each night over a four-week period.

What were the key differences between the PSWT and sham groups?

Both groups reported pain reduction at 4 weeks, but only the PSWT group maintained pain relief at 6 weeks after device use was discontinued, with the difference being statistically significant (p value of .02).

Is pulsed shortwave therapy safe to use?

Yes, PSWT was found to be safe and well tolerated with infrequent, mild adverse events (most commonly minor skin irritation from adhesive tape) and no serious adverse events reported.

What is pulsed shortwave therapy (PSWT) and how does it work?

PSWT is a non-invasive electromagnetic therapy designed to reduce pain and improve quality of life in patients with chronic musculoskeletal conditions, with no systemic side effects and can be self-administered at home.

How does PSWT compare to current thumb arthritis treatments?

Unlike current limited treatment options involving splints, medications, or injections, PSWT offers a drug-free alternative that provides sustained pain relief and can be used conveniently at home.

What product uses PSWT technology and how affordable is it?

BioElectronics’ ActiPatch is available over-the-counter and costs less than a nickel per hour of use, making it an affordable, effective, drug-free solution for arthritis pain.
