Ultrasonographic Subcutaneous Scar Scoring System for Traumatic Hand Injured Patients

Development of a Subcutaneous Scar Scoring System Via Ultrasonography and Its Association With Hand Function in Traumatic Hand Injured Patients

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.

Inclusion Criteria:

• Able to do active motion and resistive activities
• Understand and cooperate the experiment

Exclusion Criteria:

• Injured by burn
• Have impairment in peripheral nerve and affect the movement
• Combined with other central nerve deficits
