Evaluation of a Proximal Block Site and the Use of Nerve-Stimulator-Guided Needle Placement for Posterior Tibial Nerve Block.

Few significant differences were seen between groups, but involvement of the median nerve was significantly less frequent in patients without conduction block. This was also true of proximal weakness.

Mixed inhibitors do not bind directly in the active site, and therefore do not block substrate binding, but instead bind at sites that can be proximal or distal from the active site.
