Collagen fibers in the groups receiving pressure garment therapy (PGT) were oriented in two primary directions whereas controls were oriented parallel to the circumference of the pig (the vertical axis in each image). After cessation of PGT, collagen fibers within the pressure released group became more uniformly oriented in one direction. This increase in alignment continued until the end of the experiment (Week 29).
