Objective
To assess the efficacy of spinal manipulation for the patients with acute low back pain.

Method
Twenty patients with acute low back pain have been received spinal manipulation 3 times per week. The 10-point scale and the distance of the fingertips from the floor on maximum forward flexion (fingertip-flexion test) were checked pretreatment, immediately posttreatment, 2 days posttreatment, 1 week posttreatment, and 2 weeks posttreatment.

Results
The results were as follows: 1) The 10-point scale at pretreatment, immediately posttreatment, 2 days posttreatment, 1 week posttreatment, and 2 weeks post-treatment were 10.0⁑0.0, 5.8⁑1.4, 2.2⁑1.0, 1.1⁑0.2, and 1.0⁑0.0, respectively (P＜0.01). 2) The fingertip-flexion test at pretreatment, immediately posttreatment, 2 days posttreatment, 1 week posttreatment, 2 weeks posttreatment were 35.4⁑8.4 cm, 22.4⁑7.0 cm, 14.1⁑4.9 cm, 7.4⁑3.6 cm, and 5.4⁑4.6 cm, respectively (P＜0.01).

Conclusion
In our study, the spinal manipulation for the patients with acute low back pain offered significant efficacy and appeared to be a reasonable therapeutic option. But the effectiveness of this method leaves a critical aspect that should be dealt with in future studies.
