Pumping manipulation was used as a treatment for reduction of articular disc displacement in the temporomandibular joint disorder. 41closed lock cases of internal derangement of the temporomandibular joint were treated by this technique, and had obtained satisfactory effects about increasing of maximum mouth opening and resolving of pain. In spite of their effects, many cases had not obtained reduction of articular disc displacement in during treatment. So we investigated the relation of disc reduction to improvement symptoms (increasing of mouth opening and pain free). The results were follows.
A) About clinical effects
1) In 32 cases, over 40mm opening (78.0%)
2) In 35 cases, pain free (85.4%)
3) In 30 cases, obtained of both effects (73.2%)
4) In 4 cases, no effects (9.8%)
B) About reduction of disc displacement
1) In 3 cases, reduction and soon opening (9.4%)
2) In 6 cases, reduction and soon locking, but opening later (18.8%)
3) In 8 cases, no reduction and soon opening (25.0%)
4) In 15 cases, no reduction and opening later (46.8%)
In above mentioned, clinical effects of pumping manipulation therapy depend on the various kind of effect as well as disc reduction.
