Musculoskeletal Ultrasound Imaging (MSKUS) offers real-time imaging of muscles, ligaments, bone surfaces and tendons by using sonic waves. It is non-invasive and may be used to assist you and your Doctor of Physical Therapy to locate a diastasis recti, determine if your emptying your bladder completely, or teach you how to contract your transverse abdominus muscle - which is paramount to learning how to flatten your abdomen.
