In this study, group one served as the control group. They had their blood pressure taken with their feet on the floor. While group two served as the test group. This group had their blood pressure taken with their legs crossed. Then both groups are compared to each other. In the second portion of the study the roles were reversed. On the other hand the qualitative study uses descriptive phenomenology.
