In this paper, studies are performed on a large number of diabetic patients belonging to different classes, using new on-line foot pressure parameters, i.e. normalized peak pressure (NPP) and pressure contact ratio (PCR), which include effects of the weight of the subject, velocity of walking and duration of high pressures in any region of the foot. A statistical study of the mean maximum value of these parameters in different plantar areas of the feet, for different classes of diabetic subjects, indicates distinguishing trends and hence could aid the clinician in better diagnosis and therapy planning. The NPP and PCR transforms calculated on-line (using specially developed software) help the clinician to quickly determine the heavily loaded foot areas that are potential sites of ulceration in insensitive feet and take the necessary action to prevent further damage to the foot sole.
在本文中，使用新的在线足部压力参数，即归一化峰值压力（NPP）和压力接触比率（PCR），对大量不同类型的糖尿病患者进行了研究，这些参数包括受试者体重、行走速度以及足部任何区域高压持续时间的影响。对不同类型糖尿病受试者足部不同足底区域这些参数的平均最大值进行的统计研究显示出明显的趋势，因此有助于临床医生进行更好的诊断和治疗规划。在线计算的NPP和PCR变换（使用专门开发的软件）可帮助临床医生快速确定在感觉迟钝的足部中可能发生溃疡的高负荷足部区域，并采取必要措施防止足底进一步受损。
