Comfort Day 1 Subjects will be asked to provide a subjective rating of brace comfort using a 10cm visual analog comfort rating scale for each of the back braces during all ROM and ADL testing conditions. The endpoints of the scale will be labeled "Very comfortable", and "Very uncomfortable" at 0 and 10cm respectively.
