  • A safe route for deep pelvic biopsy with distention of the Iliacus Muscle.
    Journal of vascular and interventional radiology : JVIR, 1991
    Co-Authors: Philip Carlson, Andrew B. Crummy, Myron Wojtowycz, John C. Mcdermott
    Abstract:

    To avoid bowel perforation during deep pelvic biopsy, the authors describe a technique in which the Iliacus Muscle is distended by injecting it with a solution of lidocaine and saline. This Muscle distention causes sufficient bowel displacement to allow safe advancement of biopsy needles as large as 14 gauge through the distended Muscle belly to the region of interest.

  • Relative EMG levels in training exercises for abdominal and hip flexor Muscles.
    Scandinavian journal of rehabilitation medicine, 1998
    Co-Authors: Eva Andersson, Alf Thorstensson
    Abstract:

    The main purpose of our study was to compare systematically EMG levels in sub-maximal training exercises for the trunk and hip flexor Muscles with those voluntarily attainable in corresponding situations. Six healthy subjects performed three types of standardized training exercises, whose static positions, movement velocity and range of motion were reproduced during maximal voluntary isokinetic strength tests. EMG was recorded with wire electrodes from the Iliacus Muscle and with surface electrodes from the rectus femoris, sartorius, rectus abdominis, obliquus externus and internus Muscles. The relative EMG values demonstrated a task dependency which could differ between individual Muscles. The maximal voluntary activation levels were relatively constant across conditions. Exceptions were present, particularly for the rectus femoris and Iliacus Muscles. These findings highlight the consequences of using different methods of normalizing EMG. The relative EMG values presented may serve as guidelines when selecting training exercises for specific trunk and hip flexor Muscles in sports and rehabilitation.

  • abdominal and hip flexor Muscle activation during various training exercises
    European Journal of Applied Physiology, 1997
    Co-Authors: Eva Andersson, Johnny Nilsson, Alf Thorstensson
    Abstract:

    The purpose of this study was to provide objective information on the involvement of different abdominal and hip flexor Muscles during various types of common training exercises used in rehabilitation and sport. Six healthy male subjects performed altogether 38 different static and dynamic training exercises trunk and hip flexion sit-ups, with various combinations of leg position and support, and bi- and unilateral leg lifts. Myoelectric activity was recorded with surface electrodes from the rectus abdominis, obliquus externus, obliquus internus, rectus femoris, and sartorius Muscles and with indwelling fine-wire electrodes from the Iliacus Muscle. The mean electromyogram amplitude, normalised to the highest observed value, was compared between static and dynamic exercises separately. The hip flexors were highly activated only in exercises involving hip flexion, either lifting the whole upper body or the legs. In contrast, the abdominal Muscles showed marked activation both during trunk and hip flexion sit-ups. In hip flexion sit-ups, flexed and supported legs increased hip flexor activation, whereas such modifications did not generally alter the activation level of the abdominals. Bilateral, but not unilateral, leg lifts required activation of abdominal Muscles. In trunk flexion sit-ups an increased activation of the abdominal Muscles was observed with increased flexion angle, whereas the opposite was true for hip flexion sit-ups. Bilateral leg lifts resulted in higher activity levels than hip flexion sit-ups for the Iliacus and sartorius Muscles, while the opposite was true for rectus femoris Muscles. These data could serve as a basis for improving the design and specificity of test and training exercises.
