Isokinetic and functional parameters in patients following reconstruction of the anterior cruciate ligament

Methodological Report: Dynamic Field Tests Used in an NFL Combine Setting to Identify Lower-Extremity Functional Asymmetries

“…(6, 16, 18, 19, 29, 35) Functional hop tests such as the single leg hop, cross-over hop, triple hop, and timed hop have been used to evaluate ACL injury rehabilitation progress. (32) However, many of these functional hop tests have a low sensitivity and specificity for determining lower extremity asymmetries (16) and these movements do not take into account other high risk multi-planar movements, such as perpendicular cutting and challenging lateral motions.…”

Measurement properties of performance-based outcome measures to assess physical function in young and middle-aged people known to be at high risk of hip and/or knee osteoarthritis: a systematic review

“…Six of the 10 measurement properties outlined in COSMIN were evaluated in the 20 included studies (Table I). These were reliability 23e26,28e30,32,40 and hypothesis testing 27,33e39,41 in nine studies each, measurement error in three studies 25,30,32 , structural validity in two studies 31,42 , and interpretability 23 and 31 e e Co-contraction test 33,38 e e e e Shuttle run test 36,37 e e e e Carioca test 36,37 e e e e Figure- responsiveness 30 in one study each. Other measurement properties described in COSMIN such as internal consistency, criterion validity, content validity or cross-cultural validity were not assessed in any of the included studies.…”

“…Validity studies (Table III) In people with ACL reconstructions, the one-legged hop for distance was rated positive on hypothesis testing in two "fair" quality studies 39,41 . Two other "fair" quality studies were rated negative 27,36 and one was rated indeterminate 37 . The 6-m timed hop test and the crossover hop for distance were positive rated for hypothesis testing in one "fair" quality study 39 , but the crossover hop for distance was rated negative in another "fair" quality study 36 .…”

“…Two other "fair" quality studies were rated negative 27,36 and one was rated indeterminate 37 . The 6-m timed hop test and the crossover hop for distance were positive rated for hypothesis testing in one "fair" quality study 39 , but the crossover hop for distance was rated negative in another "fair" quality study 36 . The triple hop for distance was rated positive for both hypothesis testing and structural validity in two "fair" quality studies 31,41 and the stairs hopple test was rated positive for structural validity in one "fair" quality study 31 .…”

Relative muscle contribution of lower extremity muscles during isokinetic single leg squat in patients following reconstruction of the anterior cruciate ligament

“…So it is used as a functional clinical test to assist practitioners in examining the lower extremity kinetic chain [25]. To our knowledge there is no study assessing the SLS isokinetic dynamometry in ACLRP and previous studies were conducted on open kinetic chain [27,28].…”
