Randomized Controlled Trial Clinical TrialThe reliability of multitest regimens with sacroiliac pain provocation tests.
Studies concerning the reliability of individual sacroiliac tests have inconsistent results. It has been suggested that the use of a test regimen is a more reliable form of diagnosis than individually performed tests. ⋯ A multitest regimen of 5 sacroiliac joint pain provocation tests is a reliable method to evaluate sacroiliac joint dysfunction, although further study is needed to assess the validity of this test method.

Clinical Trial Controlled Clinical TrialFirst Prize: Central motor excitability changes after spinal manipulation: a transcranial magnetic stimulation study.
The physiologic mechanism by which spinal manipulation may reduce pain and muscular spasm is not fully understood. One such mechanistic theory proposed is that spinal manipulation may intervene in the cycle of pain and spasm by affecting the resting excitability of the motoneuron pool in the spinal cord. Previous data from our laboratory indicate that spinal manipulation leads to attenuation of the excitability of the motor neuron pool when assessed by means of peripheral nerve Ia-afferent stimulation (Hoffmann reflex). ⋯ When motor neuron pool excitability is measured directly by central corticospinal activation with transcranial magnetic stimulation techniques, a transient but significant facilitation occurs as a consequence of spinal manipulation. Thus, a basic neurophysiologic response to spinal manipulation is central motor facilitation.
