Differences at the Achilles Insertion Between Adults with Insertional and Midportion Achilles Tendinopathy as Observed Using Ultrasound

SUMMARY Background. The purpose of this study was to determine structural and pathological differences of Achilles tendon insertion between insertional Achilles tendinopathy (IAT) and midportion Achilles tendinopathy (MidAT) in both injured and uninjured sides. Methods. Patients (n = 34; 58.8% male) with unilateral Achilles tendinopathy (50% with IAT; 50% with MidAT) were recruited. Median age … Continued

Investigation of the Contraction Ratio of Transversus Abdominis and Internal Oblique Muscles during Lumbopelvic Stability Test

SUMMARY Background. The clinicians administer lumbopelvic stability test (LPST) to evaluate core stability of lumbar spine and TrA muscle function. While the reduced thickness and contraction ratio of the TrA was well documented among people with nonspecific low back pain (NSLBP), the direct morphological changes of TrA during the LPST had not been reported so … Continued

Quantifying the Dimensions of Achilles Tendon Insertional Area Using Ultrasound Imaging A Validity and Reliability Study

SUMMARY Background. The purpose of this study was to evaluate the reliability and validity of using US imaging for measuring Achilles tendon insertion area to the calcaneus. Methods. Sixteen cadaveric tendons were used to compare the agreement between Achilles tendon insertion length measurements from US images with actual measurements after dissection. In addition, test-retest reliability … Continued
