Rehabilitative Ultrasound Imaging of Pelvic Floor Muscle Function

Jackie L. Whittaker, Judith A. Thompson, Deydre S. Teyhen, Paul W. Hodges
SYNOPSIS: This commentary provides an overview of the current concepts and evidence related to rehabilitative ultrasound imaging (RUSI) of pelvic floor (levator ani) function. As this is an emerging topic, the goal is to provide a basic understanding of ultrasound imaging applications related to levator ani function: the available quantitative and qualitative information, the limitations, as well as how ultrasound imaging can be incorporated as a form of biofeedback during rehabilitation. Furthermore, as the ability to compile and compare existing evidence depends on the degree of similarity in methodology by investigators, this commentary highlight points of consideration and provides guidelines, as well as an agenda, for future investigation.

Rehabilitative Ultrasound Imaging: Understanding the Technology and Its Applications

Jackie L. Whittaker, James M. Elliott, Katy Cook, Helene M. Langevin, Haldis H. Dahl, Maria Stokes, Deydre S. Teyhen

The use of ultrasound imaging by physical therapists is growing in popularity. This commentary has 2 aims. The first is to introduce the concept of rehabilitative ultrasound imaging (RUSI), provide a definition of the scope of this emerging tool in regard to the physical therapy profession, and describe how this relates to the larger field of medical ultrasound imaging. The second aim is to provide an overview of basic ultrasound imaging and instrumentation principles, including an understanding of the various modes and applications of the technology with respect to neuromusculoskeletal rehabilitation and in relation to other common imaging modalities.

Rehabilitative Ultrasound Imaging of the Abdominal Muscles

Norman W. Gill, Julie A. Hides, Jackie L. Whittaker, Sharon M. Henry, Deydre S. Teyhen, Paul W. Hodges

Rehabilitative ultrasound imaging (RUSI) of the abdominal muscles is increasingly being used in the management of conditions involving musculoskeletal dysfunctions associated with the abdominal muscles, including certain types of low back and pelvic pain. This commentary provides an overview of current concepts and evidence related to RUSI of the abdominal musculature, including issues addressing the potential role of ultrasound imaging in the assessment and training of these muscles. Both quantitative and qualitative aspects associated with clinical and research applications are considered, as are the possible limitations related to the interpretation of measurements made with RUSI. Research to date has utilized a range of methodological approaches, including different transducer placements and imaging techniques. The pros and cons of the various methods are discussed, and guidelines for future investigations are presented. Potential implications and opportunities for clinical use of RUSI to enhance evidence-based practice are outlined, as are suggestions for future research to further clarify the possible role of RUSI in the evaluation and treatment of abdominal muscular morphology and function.
