The purpose of this study is to compare the effectiveness of relative motion splint and metacarpophalangeal joint blocking splints in terms of sign and symptoms, hand function, occupational performance, and perception of splint wearability (comfort and satisfaction) after six weeks of TF management.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Relative Motion Splint | Experimental | In the relative motion splint, the metacarpophalangeal joint of the affected finger(s) positioned in approximately 20°-25° more extension/flexion than metacarpophalangeal joint of the adjacent fingers. |
|
| Metacarpophalangeal Joint Blocking Splint | Active Comparator | In the metacarpophalangeal joint blocking splint, the metacarpophalangeal joint of the affected finger(s) positioned in 0°. |

| Measure | Description | Time Frame |
|---|---|---|
| Stages of Stenosing Tenosynovitis (SST) | SST is a grading system that divides trigger finger into six stages. Stage 1 is normal; Stage 2 is uneven finger movement; Stage 3 is triggering or clicking or catching; Stage 4 is locking of finger in flexion or extension, which can be unlocked by active finger movement; Stage 5 is locking of finger in flexion or extension, which requires application of passive force to unlock; and Stage 6 is locked finger in flexion or extension | Baseline, 6 weeks after splint wear |
| Measure | Description | Time Frame |
|---|---|---|
| Visual Analog Scale (VAS) for pain | The left end of the VAS labelled as "no pain" and the right end labelled as "extreme pain". | Baseline, 6 weeks after splint wear |
| Number of triggering events in ten active fists |

| Metacarpophalangeal Joint Blocking Splint |
| Other |
Six weeks metacarpophalangeal joint blocking splint wear. |
|
The number of triggering events (0 - 10) can be obtained by asking the patient to make 10 active full fists.
| Baseline, 6 weeks after splint wear |
| Disabilities of the Arm, Shoulder and Hand (DASH) Outcome Measure | DASH is a 30-item, self-report questionnaire that range from 0-100 score, with higher scores represent more severe disability or poorer hand function. | Baseline, 6 weeks after splint wear |
| Canadian Occupational Performance Measure (COPM) | COPM is a interview-based assessment tool for measuring occupational performance. The importance, satisfaction, and performance of an activity are rated using a 10-point rating scale. | Baseline, 6 weeks after splint wear |
| Visual Analog Scale (VAS) for splint comfort | The left end of the VAS labelled as "not at all comfortable' and the right end labelled as "extremely comfortable". | Baseline, 3 and 6 weeks after splint wear |
| Visual Analog Scale (VAS) for splint satisfaction | The left end of the VAS labelled as "not at all satisfied" and the right end labelled as "extremely satisfied". | Baseline, 3 and 6 weeks after splint wear |
