(i) The argument method='bootstrap.t' invokes pivot tests for the exclusion of a null value from Gaussian confidence interval, using on resampled estimates of the mean and variance of the global statistic; (ii) method='bootstrap.q' invokes tests based on the exclusion of a null value from the alpha-quantile interval of the resampled global statistic.
Instead, RhoE gt/gt mice were hypoactive in early time points (PD5 7), with less pivotings and longer latency to walk than their siblings, and showed a delayed neuromotor development characterized by the persistence of the immature motor pattern in the pivoting test and a delay in the appearance of a normal gait pattern.
Prior to testing, the participants had to undergo clinical examination of both knee joints, including the Lachman and drawer tests, the pivot shift test, as well as quantitative measurement of anterior stability using the Rolimeter in 30° and 90° of flexion.
A special pivoting testing frame is conceived to apply cyclic, uniformly distributed inertia-like forces.
Clinical tests for assessment of rotational laxity, such as the pivot shift test or the Losee test were subsequently developed [ 16, 17, 30, 36].
In the acute ACL tears, the pivot shift test was the most sensitive test (0.89), followed by the Lachman test (0.78).
Data include manual Lachman, instrumented Lachman with a Rolimeter measurement device, the pivot shift test, and manual dial test.
In the clinical practice, the Lachman and anterior drawer tests are used for testing anterior stability of the knee, while the pivot shift test is applied to check for rotational stability.
Signs of instability are redislocation, a positive pivot shift test, positive valgus and varus stress testing, and radiographic incongruence.
All patients underwent clinical examination after closed reduction (ROM, lateral pivot shift test, varus-valgus stress), preoperative X-ray examination, and CT scan; they then underwent clinical and radiographic follow-up evaluations at 1, 3, and 6 months.
