Study summary

To determine if the addition of Astym treatment to traditional therapy produces a more positive outcome then traditional therapy alone for the treatment of de Quervain's tenosynvitis. Two groups will be examined with one group receiving traditional therapy and the other group receiving traditional therapy in addition to Astym treatment protocol.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

ii. Persistent symptoms for >3 wks which have not resolved after an additional 3 weeks of splinting

iii. A diagnosis by a physician of "de Quervain's", "fist compartment tenosynovitis", or "radial styloid tenosynovitis"

iv. Patients must agree and comply to a predetermined splinting regimen

Exclusion criteria

Exclusion Criteria:

i. History of cortical injection to affected wrist and/or thumb

ii. History of previous wrist trauma to affected limb

iii. Comorbidity such as carpal tunnel syndrome (CTS), radial tunnel syndrome, osteoarthritis, rheumatoid arthritis, auto-immune disease or inflammatory conditions, lateral epicondylitis or tendinopathies

iv. Clotting deficits

v. Positive Cozen's sign which would indicate intersection syndrome

vi. Post-partum mothers \<6 months and pregnant women

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Numeric Rating Scale for Pain

    This scale is a single point scale from 0-10. The participant picks one number to represent their pain, where 0 represents no pain and 10 represents worst pain imaginable.

    Time frame: 4.5 months

Secondary outcomes

  1. Sequential Occupational Dexterity Assessment (SODA) Score

    This is a test to measure dexterity and bimanual abilities in activities of daily living. It includes 12 tasks with participants being scored on their ability, difficulty and pain during the task. Scores on the individual tasks are summed, and the range of the total SODA score is 0-108. A higher score indicates a higher dexterity.

    Time frame: 1.5 months

  2. Quick Dash Score

    It is a questionnaire that measures an individual's ability to complete tasks, absorb forces, and severity of symptoms. The QuickDASH tool uses a 5-point Likert scale from which the patient can select an appropriate number corresponding to his/her severity level/ function level. QuickDASH Scoring Formula = (\[(sum of n responses)/n\] -1)(25) where n represents the number of completed items. Higher scores indicate a greater level of disability and severity, whereas, lower scores indicate a lower level of disability. The score on both test ranges from 0 (no disability) to 100 (most severe disability).

    Time frame: 4.5 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2015 to primary completion in Apr 2019, 51 months.

Results were first posted in Oct 2020, 1 year 5 months after primary completion.

Of 16 interventional studies with no phase under De Quervain Disease, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 28. This study's 51 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 9, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
