Read the detailed description
This study aims to analyse and compare the effectiveness of metacarpophalangeal joint blocking splint versus relative motion extension splint for trigger finger. This will help us find out which one of the two splint designs is more effective in the management of trigger finger, thus improving treatment outcomes for patients with trigger finger.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Comparison of splints for trigger finger
| Study group | Role | What they receive |
|---|---|---|
| Splint M | Active comparator | Metacarpophalangeal joint blocking splint Receives: Other: Splint |
| Splint R | Experimental | Relative motion extension splint Receives: Other: Splint |
What is being measured
The primary outcome is the main question the study is designed to answer.
Green's classification for trigger finger
Green's classification is an objective outcome measure. The therapist grades the triggering by observing the finger when the patient makes a full fist.
Grade I: Pain/history of catching Grade II: Demonstrable catching but can actively extend digit Grade III: Demonstrable locking, requiring passive extension Grade IV: Fixed flexion contracture
Lowest score is I; highest score is IV
Measured: 12 weeks
Secondary outcomes (1)
QuickDASH (Disability of Arm, Shoulder and Hand)
The QuickDASH is a patient rated questionnaire that rates patient's ability to perform certain tasks as well as severity of symptoms. The best score is 0 (no difficulty) and the lowest score is 100 (severe difficulty).
Measured: 12 weeks
