Abstract：
Finger photo pulse plethysmography is a simple, inexpensive and non-invasive method for measurement of arterial stiffness. The objective is to assess the correlation of arterial stiffness in low back pain subjects with lumbar disc degeneration. Thirty-four back pain patients of both sexes in age group of 30-65 were included. Anthropometric measures like height, body weight, body mass index (BMI) were included. Stiffness index (SI) and reflection index (RI) were measured from the digital volume pulse waveform. There was a negative correlation between SI/RI and no correlation between SI and RI with BMI in both sexes. A significant correlation found between weight and BMI in both sexes. Arterial stiffness may not have any influence on disc degeneration. BMI showed some influence on disc degeneration and back pain.
摘要：
手指照片脉冲体积描记术是一个简单的，测量动脉硬度的廉价和非侵入性的方法。目的是评估下背痛受试者的动脉僵硬度与腰椎间盘退变的相关性。包括30-65岁年龄段的34名男女背痛患者。人体测量，如身高，体重,包括体重指数（BMI）。从数字体积脉冲波形测量刚度指数(SI)和反射指数(RI)。男女SI/RI与BMI呈负相关，SI和RI与BMI无相关性。男女体重与BMI之间存在显着相关性。动脉僵硬度可能对椎间盘退变没有任何影响。BMI对椎间盘退变和背痛有一定影响。
