Single Hop Test Single leg hop test (Reid et al, 2007) Subjects stand on one leg and hop as far forward as possible and land on the same leg. The distance is recorded from toe at take-off to heel at landing with a tape measure which is fixed to the ground. Two valid hops are performed, with the average (mean) of the 2 being used for calculation. Hypothesis/Purpose. The purpose of this study was to examine the relationship between ACL-RSI scores and limb symmetry index (LSI) for the single hop for distance (SHD), triple hop for distance (THD), crossover hop for distance (CHD), timed 6-meter hop (T6H), and single leg vertical hop (SLVH) in a cohort of National Collegiate Athletic Association (NCAA) .Anterior cruciate ligament (ACL) rupture is a common orthopedic injury with an incidence of 30–78 per 100 000 person years . . activation, cross sectional area of vastus medialis, single leg hop test and step length symmetry). (2) Functional outcomes between groups were not significantly different (IKDC, Lysholm, Tegner) I've previously posted about the single leg hop test and its role in the decision-making process regearding return to sport following lower limb injury. Now, I'll cover the 4 hop test battery that is commonly used in return to sport testing following ACL surgery (SEE picture above). 2 recent studies (Kyritsis et al., 2016 & Grindem et al, 2016) show that athletes were .

Single hop for distance . In 91 people with ACL injury treated non-operatively, a hop for distance limb symmetry index (LSI=injured leg ÷non-injured leg) of <88% at 2.5 months after injury predicted worse self-reported knee function (ie. IKDC score) 1 .Purpose: There is a lack of objective factors which can be used in guiding the return to sport (RTS) decision after an anterior cruciate ligament reconstruction (ACLR). The purpose of the current study was to conduct qualitative analysis of the single leg hop (SLH) in patients after ACLR with a simple and clinical friendly method and to compare the possible difference in .
The one leg hop for distance is one of the most commonly employed functional tests utilized in the evaluation of the ACL deficient and reconstructed patient.
