The effects of maxillary MORA's on strength and muscle efficiency tests.

Abstract

AbstractThe study described in this article tested mandibular orthopedic repositioning appliances (MORA's) on eleven athletes to determine changes in muscle strength and efficiency (power) during various exertions. In the vertical jump and grip tests, a significant increase in muscle efficiency was recorded. An average increase of 5% in vertical jump was noted for the eleven subjects. All of the subjects showed an increase in the grip test, with a mean of 17.3%. However, there was no significant increase in strength recorded for the maximum hip sled or the bench press test.
