THOMAS TEST FOR ILIOPSOAS LENGTH The Thomas Test is a great quick test to assess the length of your patients hip flexors. If the the extended leg does not remain on the treatment bench during contralateral hip flexion, this is a sign of a shortened iliopsoas muscle. Peeler et al. (2007) have evaluated the test's reliability and found an intra-rater reliability of 0.47 and an inter-rater reliability of 0.52 for the visual method. Using a goniometer yielded slightly better results. Nonetheless, th

If the the extended leg does not remain on the treatment bench during contralateral hip flexion, this is a sign of a shortened iliopsoas muscle. Be aware that our abdominal muscles and the iliopsoas have to work together smoothly. If the abs are not able to stabilize the spine in a neutral position against the iliopsoas (which pulls the lumbar spine into extension

HIP ASSESSMENT SERIES PART 13: THOMAS TEST FOR ILIOPSOAS TIGHTNESS Hip flexion can be impaired not only to a tight rectus femoris muscle but more often than not due to tightness of the iliopsoas muscle. The Thomas test is the most common quick test to assess for contractures or tightness of this muscle that runs from the lateral part of the segments T12-L4 and the iliac fossa to the lesser trochanter. | Physiotutors
