Evaluating Hand Function in Clients with Trigger Finger.
Danit Langer, Adina Maeir, Michael Michailevich and 1 others
PMID 29097982WHAT IT FOUND
In people with trigger finger, the Purdue Pegboard Test tracked severity, while the Functional Dexterity Test and grip strength did not.
All tests distinguished trigger finger from controls, and affected-hand scores related moderately to self-reported disability except the affected-hand Purdue Pegboard subtest.
Key findings
01The Purdue Pegboard Test showed lower scores as trigger finger severity increased, while the Functional Dexterity Test and grip strength did not show clear severity differences.
02The hand function tests distinguished clients with trigger finger from healthy controls, with controls scoring better.
03The affected-hand test scores correlated moderately with disability, except for the affected-hand Purdue Pegboard subtest.

What it does not show
This was a single-time assessment study, so it cannot show how hand function changes over time or responds to treatment. Only trigger finger grades 1 to 3 were analysed, so the findings do not cover clients with fixed deformity grade 4. The healthy controls were recruited by convenience sample, which may limit how well they represent the wider population. The radial-side and ulnar-side groups were unequal, with 44 and 19 participants, so the lack of difference between sides should be read cautiously. The DASH work, sport, and music modules were not included, so the disability measure may not capture all relevant functional demands.
The easy way to misread this
Do not assume all the tests can track trigger finger severity. The Purdue Pegboard Test did, but the Functional Dexterity Test and grip strength did not show clear severity differences.
