Trigger Finger, Shockwave Therapy
Conditions
Keywords
trigger finger, shockwave
Brief summary
The goal of this study is to compare the effects of extracorporeal shockwave therapy and splinting in the treatment of trigger finger. Participants will: Be randomized into two groups (shockwave group and splint group). Visit the clinic once a week for four weeks for therapy. Keep a diary of their symptoms, which will be reviewed at six weeks.
Interventions
DEVICEShockwave
In the Shockwave group, will be applied focused shockwaves therapy of 1500 impulses at 0.01 mJ/mm2 over the painful area or the pathologic flexor tendon to each participant under the supervision of a physiatrist. The ESWT will be conducted once weekly for 4 weeks with a sham splint (DIP joint blocking splints) for at least 8 hours per day for 6 weeks.
DEVICESplint
In the splinting group, will be provided a PIP blocking splint at least 8 hours per day for 6 weeks with the sham shockwave (the patients close their eyes, extend their hand through a partition, apply shockwave device head with gel on the patient's finger, and play a mobile phone sound that mimics the sound of a real shockwave machine) once a week for 4 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 100-mm. horizontal VAS score | at enrollment, fourth week, and sixth week after first intervention | The VAS or Visual Analog Scale is a scale that is used to evaluate the level of pain. It is represented by a horizontal line that is 100-mm. long. The score is determined by measuring the distance in mm. A higher score on this scale indicates greater pain intensity. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| QuickDASH score | at enrollment, fourth week, and sixth week after first intervention | The QuickDASH or Quick Disabilities of the Arm, Shoulder and Hand is a questionnaire that is used to evaluate the ability to perform activities of the arm, shoulder, and hand. It consists of 11 questions that patients are required to answer all of them. The answers are summarized in a range of 0-100, where a higher score indicates greater disability. |
| Number of triggering | at enrollment, fourth week, and sixth week after first intervention | The number of triggering events in ten active full fists will be scored out of ten. If a participant's finger remain locked at any time in making ten active full fists, they will be asked to stop and given a score of 10/10 |
