Abstract :Demonstrate movement of the Interosseous Membrane insert ignore into journalissuearticles values(IM); when tensile loading was applied to the Tibialis Anterior insert ignore into journalissuearticles values(TA); and Tibialis Posterior insert ignore into journalissuearticles values(TP);. Postulate new roles for IM in running. Nine IMs were assessed by 2 examiners. Dissections exposed the TA and TP. Posterior IM was palpated under TP as tensile loading of TA applied. Anterior IM was palpated under TA, as tensile loading of TP applied. Tensile loading was measured via a spring scale attached to distal tendons of TA and TP. TA tensile loading caused movement of IM anteriorly. TP tensile loading caused movement of IM posteriorly. T-test revealed no statistically significant difference between two examiners. The IM moves when TA and TP muscles undergo tensile loading. Rapid TA contraction during running pulls on the IM, pre-stretching TP and resulting in a forceful TP contraction. The IM is an important factor in pre-stretching of TA and TP. Nerve endings found in IM in our previous publication can increase afferent signal input and coordinate muscle activation of anterior and posterior IM muscles; IM acts as both a tendon and ligament; IM can coordinate muscular activity at heel strike and toe-off; IM limits separation of the distal tibio-fibular joint at heel strike; IM attenuates vertical ground reaction forces.
