Thumb osteoarthritis, also known as rhizarthrosis, can cause functional discomfort and sometimes significant daily pain.

Faced with the limitations of medication, or a desire to explore gentler approaches, some people turn to alternative solutions such as magnet therapy.

But what can we realistically expect from it? Is it a credible option, or simply an unfounded belief? This page explores the topic in an objective and balanced way.

Magnet therapy is often mentioned among complementary and alternative approaches for thumb osteoarthritis, alongside essential oils, dietary supplements or osteopathy.

What is magnet therapy?

Magnet therapy is based on the idea that magnetic fields, applied locally, may have beneficial effects on biological tissues.

It usually involves:

  • Static magnets placed on the skin (bracelets, splints or patches),

  • Or devices emitting pulsed electromagnetic fields, most often used in specialised clinics.

The intended aim is to stimulate blood circulation, reduce inflammation and relieve pain.

These effects are sometimes compared to those of certain physiotherapy or electrotherapy techniques, which are more strictly regulated and medically supervised.

What does scientific research say?

To date, evidence supporting the effectiveness of magnet therapy in treating thumb osteoarthritis remains limited and controversial.

Some small-scale studies suggest a potential benefit for chronic pain or musculoskeletal conditions, but their methodologies are frequently criticised due to:

  • Small sample sizes,

  • Lack of double-blind protocols,

  • Placebo effects that are difficult to rule out.

Specifically for thumb osteoarthritis, data are almost non-existent, and no official medical guidelines currently recommend magnet therapy as part of standard care.

Perceived benefits… but not scientifically proven

Some people with thumb osteoarthritis report temporary relief after using magnetic devices.

This may be explained by several factors:

  • The placebo effect, which is genuine and can sometimes be powerful,

  • Increased attention to the painful area (rest, gentle movement),

  • The compressive or stabilising effect of certain magnetic supports.

However, it is important to note that perceived improvement should never replace a proper medical assessment, especially if pain becomes persistent or disabling.

An approach to consider with caution

If you are considering trying magnet therapy, the following points may be helpful:

  • Choose simple, non-invasive devices without unrealistic claims.

  • Avoid expensive or non-certified equipment.

  • Never stop or alter an ongoing medical treatment without consulting your doctor.

  • Pay close attention to your symptoms: if pain worsens or does not improve, seek professional advice promptly.

Magnet therapy generally poses no major risk in most cases, but it should not replace appropriate medical management of thumb osteoarthritis.

Exploring other complementary options

If you are looking for natural or alternative ways to better manage thumb osteoarthritis, other approaches may be worth considering.

These include:

  • Natural treatments,

  • Dermotherapy and cryotherapy,

  • Assistive devices to improve grip,

  • Psychological approaches to pain management.

Finally, if pain persists or functional limitation becomes significant, seeking specialist advice may be appropriate.
