The purpose of this study is to determine the reliability and concurrent validity of the figure-of-eight method of measuring hand edema in the burn patient population. Establishing the reliability and validity would enable a more time efficient assessment than the currently accepted methods.

A prospective study involving 33 burn patients admitted to the US Army Burn Center. Two raters will perform three separate blinded measurements for hand edema using the figure-of-eight measurement technique. A third rater will then perform two blinded measurements using water volumetry. All measurements will be read and recorded by an independent recorder. The three measurements of rater 1 and 2 will be analyzed to determine intratester reliability. The average of the three figure-of-eight measurements will be compared to measure intertester reliability. The two volumetry measurements will be compared to determine intratester reliability. The average of the 2 volumetry measurements and the average fo the three figure-of-eight measurements will be used to determine concurrent validity.

Inclusion Criteria:

• Male or female 18-89 years old
• Admitted to the United States (U.S.) Army Burn Intensive Care Unit (ICU) or ward with burn injury and the presence of bilateral or unilateral hand edema

Exclusion Criteria:

• Subject unable to be placed in test position for volumetry testing or the presence of a medical condition, as defined by a physician, that precludes the safe use of volumetry.
• Subject is unable to tolerate his/her hand(s) being immersed in room temperature water for volumetry testing.
• Subject does not have any of the bony landmarks (due to amputation, previous surgery) required to perform the figure-of-eight measurement
