摘要

Our study enrolled 24 patients (11 men, 13 female) with acute low back pain and 48 healthy subjects (25 male, 23 females). Visual analogue scale (VAS) for pain, pain drawing and foot pressure were evaluated. Foot pressure was measured by Footscan (RSscan Inc., Belgium) with 6.3.4.3. Software. Foot pressure measured variables including contact time, percentage of contact time, maximal plantar pressure (Pmax) and Pressure-time integral were collected. Independent t test was used to analyze the data. The results revealed that the contact time in persons with acute low back pain was longer than that of the control subjects (p＜0.05), especially in big toe (T1) and heel (H) (p＜0.05). Right heel and forefoot were delayed at time of initial contact on the ground in persons with acute low back pain (p＜0.05). Compared with control group, persons with acute low back pain had lower standardized Pmax in medial forefoot and heel (p＜0.05). The lower impulse value over right big toe area was lower than that of the control groups. Our conclusion is that subjects with acute low back pain present an asymmetric gait pattern with longer contact time as well as delayed heel strike and push-off in order to reduce the impact force from the ground, which subsequently reduce back muscle contraction and low back pain.
