The tester measured the total moved angle of lumbosacral
flexion and extension with a single inclinometer
placed over the L1-S2 spinous processes.
Statistical analyses were performed using SPSS v15.0.
The independent t-test was performed to compare the differences
in dependent variables between groups, and the
paired t-test was used to evaluate the differences within
groups. The level of probability was set at p < 0.05.
