following the manufacturer’s guidelines. To define the foot, shank, thigh, and pelvis, 14-mm retroreflective markers were attached to the right limb at the following locations: first and fifth metatarsal heads, medial and lateral malleoli, medial and lateral femoral epicondyles, and bilaterally to the

The cameras of a hybrid Vicon (Centennial, CO) MX T-Series and Bonita motion capture system surrounded two force platforms (AMTI, Watertown, MA) located in the center of the lab. The total length of the two platforms was approximately 1

of the position of the hands, irregular movement strategies were classified and clustered among the 3 major clusters of the 3-cluster solution. At trials A3, A4, and Q5, participants kept their hand(s) close to the seat at the height of their pelvis until completion of the standing movement. As a

participation in volleyball grows, it is necessary to have effective prevention programs for knee injuries in volleyball athletes. Core stability is defined as the ability to control the position and movement of the trunk over the pelvis. 5 Anatomically, the region between the diaphragm, abdominal muscles

-executed SLSq consists of an erect trunk, a level pelvis (frontal plane), a neutral hip position with no internal rotation (IR) or adduction, and the central knee aligned over the second toe during motion. 7 One of the key measures of lower limb dysfunction during SLSq is knee valgus. Knee valgus, which can

ethics approval. Instrumentation This study used six 100-Hz inertial sensors (Nanotrak; Catapult Sports, Docklands, Australia) to track trunk, pelvis, and lower limb kinematics. Inertial sensors are a validated tool for kinematic analyses ( Cuesta-Vargas, Galán-Mercant, & Williams, 2010 ; Steins, Dawes

validated by Thorborg et al. 38 For hip abduction strength testing, the HHD was placed 10 cm proximal to the lateral femoral epicondyle and the hip was placed in approximately 30° of abduction. The contralateral hip was flexed to 90° and neutral relative to rotation. The examiner stabilized the pelvis to
