Ultrasonographic Subcutaneous Scar Scoring System for Traumatic Hand Injured Patients

Study Overview
=================
Brief Summary
-----------------
This study aims to develop an objective scar scoring system via ultrasonography and try to apply it to clinical using. This study was divided into two parts. The first part of the study is an observational study design. The scar scoring system will be developed, and its test-retest reliability and criterion-related validity will be tested in this part. The second part is also an observational study design. The clinical application of the system on traumatic injured patients is conducted in the second part. The results from this scar scoring system are correlated with hand function measurements. Moreover, every scar will be recorded three times within one month during routine rehabilitation to investigate the change.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Ultrasonography platform - Healthy Group - Baseline | An ultrasonography platform and different installed modes will be used to gather the images from dominant hand of healthy adults. These data will be collected two times in healthy group to test the test-retest reliability of the system. | Baseline, 2 days after baseline | 
| Ultrasonography platform - Healthy Group - 2 days after baseline | An ultrasonography platform and different installed modes will be used to gather the images from dominant hand of healthy adults. These data will be collected two times in healthy group to test the test-retest reliability of the system. | Baseline, 2 days after baseline | 
| Ultrasonography platform - Hand Injuries Group - Baseline | An ultrasonography platform and different installed modes will be used to gather the images from affected and unaffected hand of patients with hand injuries. These data will be collected three times in hand injuries group to know how will the tissue change between different time points. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Ultrasonography platform - Hand Injuries Group - 2 weeks after baseline | An ultrasonography platform and different installed modes will be used to gather the images from affected and unaffected hand of patients with hand injuries. These data will be collected three times in hand injuries group to know how will the tissue change between different time points. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Ultrasonography platform - Hand Injuries Group - 4 weeks after baseline | An ultrasonography platform and different installed modes will be used to gather the images from affected and unaffected hand of patients with hand injuries. These data will be collected three times in hand injuries group to know how will the tissue change between different time points. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Goniometer - Hand Injuries Group - Baseline | The goniometer will be used to measure the range of motion (ROM) in the affected and affected finger. | Baseline, 2 weeks after baseline, 4 weeks after baseline |

| Hand dynamometer - Hand Injuries Group - Baseline | Hand dynamometer will be used to measure the grip strength and pinch strength. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Hand dynamometer - Hand Injuries Group - 2 weeks after baseline | Hand dynamometer will be used to measure the grip strength and pinch strength. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Hand dynamometer - Hand Injuries Group - 4 weeks after baseline | Hand dynamometer will be used to measure the grip strength and pinch strength. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Purdue pegboard test - Hand Injuries Group - Baseline | The Purdue pegboard test will be used to test the unimanual and bimanual manipulation versus hand dexterity. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Purdue pegboard test - Hand Injuries Group - 2 weeks after baseline | The Purdue pegboard test will be used to test the unimanual and bimanual manipulation versus hand dexterity. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Purdue pegboard test - Hand Injuries Group - 4 weeks after baseline | The Purdue pegboard test will be used to test the unimanual and bimanual manipulation versus hand dexterity. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Disabilities of the Arm, Shoulder and Hand - Hand Injuries Group - Baseline | The Disabilities of the Arm, Shoulder and Hand (DASH) is a questionnaire, which will be used to evaluate disorders and measure disability of the upper extremities and monitor change or function over time. | Baseline, 2 weeks after baseline, 4 weeks after baseline | 
| Disabilities of the Arm, Shoulder and Hand - Hand Injuries Group - 2 weeks after baseline | The Disabilities of the Arm, Shoulder and Hand (DASH) is a questionnaire, which will be used to evaluate disorders and measure disability of the upper extremities and monitor change or function over time. | Baseline, 2 weeks after baseline, 4 weeks after baseline |
