The purpose of this study was to compare the differences of weight-bearing distribution between subjects with low back pain and healthy subjects. Fifty-one subjects (22 men, 29 women; mean age = 42.9 years) with low back pain and 31 healthy subjects (11 men, 20 women; mean age = 35.4 years) were evaluated. The weight-bearing distribution was measured by two commercial scales during comfortable standing. The difference of weight-bearing distribution between right and left side was calculated for each subject. The differences of weight-bearing distribution in subjects with low back pain and healthy subjects were 6.0 kg and 4.5 kg, respectively. However, there were no significant differences in the weight-bearing distribution between subjects with low back pain and healthy subjects.
