RhizarthrosisNCT04115085
Study of Medical Ultrasound for Rhizarthrosis
A study testing Hand therapy (18 treatments), Therapeutic ultrasound (18 treatments) and Combined hand therapy and therapeutic ultrasound (18 treatments) in people with Rhizarthrosis, run by Waldfriede Hospital at 1 site in Germany.
Trial summary
It was never investigated which preservative non-invasive treatments are superior to treat rhizarthrosis. This randomized study compares the effect of 1. hand therapy vs. 2. therapeutic ultrasound vs. 3. hand therapy plus therapeutic ultrasound in the treatment of rhizarthrosis.

Questions about this trial
What is this clinical trial studying?
A study testing Hand therapy (18 treatments), Therapeutic ultrasound (18 treatments) and Combined hand therapy and therapeutic ultrasound (18 treatments) in people with Rhizarthrosis, run by Waldfriede Hospital at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 12 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
