However, in some conditions the heart rate during walking does\nnot reach to a steady state. Therefore, it is not possible to determine the\nenergy expenditure by use of the PCI index. The total heart beat index\n(THBI) is a new method to solve the aforementioned problem.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>OBJECTIVE:<\/jats:bold>\n                    The aim of this research project was to find the\nsensitivity of both the physiological cost index (PCI) and total heart beat index (THBI).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHOD:<\/jats:bold>\n                    Fifteen normal subjects and ten patients with flatfoot\ndisorder and twosubjects with spinal cord injury were recruited in this\nresearch project.
