Patterned Electric Dressing Effects on Open Wounds (PED)
- This study is a pilot feasibility study to determine treatment effects to estimate sample size for future studies that evaluate wound bacteria colonization.
- The secondary objective of this study aims to observe the effect of PED on an open wound and its effects in wound bacteria colonization.
