We studied to clarify the effect of passive intra-articular movement to the brain using fMRI. Stimulation of joint movement consisted of three kinds of stimulations – passive joint movement of wrist for control, passive intra-articular movement of radiolunate joint, and sacroiliac joint. Main activated areas of radiolunate joint were ipsilateral cerebellum, contaralateral insular cortex and motor cortex. Main activated areas by sacroiliac joint were contaralateral insular cortex and ipsilateral BA 7. Relief of joint pain may be modified by these brain areas to manipulate intra-articular movement. This is a first basic study of manual therapy using fMRI.
