The assessment of hip abductor activity using ultrasound imaging
MetadataShow full item record
Current assessments of hip abductor activity are limited to superficially accessible muscles. Hip pathology may be accompanied by changes in abductor activity, including deep gluteus minimus. The non-invasive assessment of hip abductor activity was evaluated using ultrasound imaging in comparison to surface and fine-wire electromyography. Measurements of abductor thickness were found irrelevant. M-mode measurements of abductor motion indicated a significant difference in the use of gluteus minimus in subjects with anterior hip pain.
