    • Variation in mechanical and activation properties of muscle fibers, tendons, and muscle architecture can affect the interpretation of muscle function from EMGs. Muscle activation may result in isometric or isotonic (even lengthening isotonic) contractions that are impossible to distinguish. However, our interpretations of the contributions of abdominal muscles to trunk bending and of the pectineus muscle to pelvic limb movement are conservative because we account for every muscle that attaches to the epipubic bones. The movements of the epipubic bones can only be produced by the muscles tested. In addition, the muscle activation resulted in musculoskeletal movement, which confirms that tension was generated during the stance phase. Thus, it is irrefutable that the abdominal muscles elevate, and the pectineus depresses these bones.

    • -1 on a motorized treadmill (19). Limb and epipubic bone movements were videotaped (at 60 fps) using a Picker Corporation Model K2601 video-fluoroscope as the animals ran on the same treadmill and speed range. Thin metal rods were implanted along each epipubic bone to visualize epipubic bone movements relative to the pelvis and hindlimb. Animal care and research protocols were in accordance with approved Ohio University Institutional Animal Care and Use Committee guidelines.
