Muscular strength and temporomandibular joint repositioning.
The relationship between physical performance and the position of the temporomandibular joint has received much attention in the past few years. Some studies have shown improvement in the physical performance with the proper alignment of the jaw. However, most of these studies lack proper experimental design. This study used a double blind and placebo design. All subjects experienced to some degree improper alignment of the temporomandibular joints. After establishing baseline data, no significant differences were found in grip strength, maximum peak torque for knee extension/flexion, or total work for knee extension/flexion. Therefore, we feel that changing the position of the temporal mandibular joint does not increase muscular strength. J Orthop Sports Phys Ther 1986;7(5):236-239.
