Back pain is one of the most common reasons for limiting daily activities, along with functional disability. The aim of this study was to investigate the relationship between some physiological and biomechanical factors associated with low back pain and postural stability in patients with nonspecific chronic low back pain.
This study is a retrospective cross-sectional study. The population consisted of all women 18-50 years of suffering from chronic non-specific low back pain (N = 15, mean age33/00±5/15 years, height162/87±4/22 Cm and weight: 68/18±4/73 Kg) and healthy (N = 15, mean age: 32/21±3/72years, height: 165/4±4/67 Cm and weight: 64/57±422 Kg). Pain sverity was measure by visual analogue scale, spine range of motion was measure by Schober test, proprioception by Newcomer test and postural stability was assessed by stabilometer. Collected Data was analyzed by independent t-test at the significant level of p≤ 0.05. Statistical analysis was performed by SPSS version 24.
The results showed that significant difference between of spinal propertiception, and center of pressure sway velocity and area in healthy women and low back pain women. There is no significant difference difference between spine range of motion of healthy women and low back pain women. There are significant and positive correlation between pain severity and postural sway velocity and area of women with back pain.
It seems that spinal proprioceptive reduce is associated with pain severity in women's low back pain. This deep sense of information impairment reduces the accuracy of sensory integration processes and, in turn, leads to inaccurate estimation of the pressure center position, thereby increasing the environment and the center of pressure displacement. Thus, this correlation can be considered as a useful tool for designing exercise rehabilitation programs for these people.
