calculated with landing of the right foot prior to the left foot defined as positive. Stance time was quantified as the time duration between the first foot initial contact and second foot takeoff. Hip centers were defined as 25% of the distance from the ipsilateral to the contralateral greater trochanters

, 4 The BESS was originally developed to diagnose and assess athletes with concussion syndrome and distinguish them from persons with no concussion. 5 In the BESS, postural control is measured in 3 positions (double-leg stance, tandem stance, and single-leg stance), each on both a firm and a foam

) qualitative investigation of female figure skaters, we adopted a social constructivist stance to view the experiences of female professional dancers through a lens of a phenomenon highly influenced by environmental and cultural factors. This approach was used to give voice to participants and enable them to

The goal of this study was to investigate clinically relevant biomechanical conditions relating to the setup and alignment of knee-ankle-foot orthoses and the influence of these conditions on knee extension moments and orthotic stance control during gait. Knee moments were collected using an instrumented gait laboratory and concurrently a load transducer embedded at the knee-ankle-foot orthosis knee joint of four individuals with poliomyelitis. We found that knee extension moments were not typically produced in late stance-phase of gait. Adding a dorsiflexion stop at the orthotic ankle significantly decreased the knee flexion moments in late stance-phase, while slightly flexing the knee in stance-phase had a variable effect. The findings suggest that where users of orthoses have problems initiating swing-phase flexion with stance control orthoses, an ankle dorsiflexion stop may be used to enhance function. Furthermore, the use of stance control knee joints that lock while under flexion may contribute to more inconsistent unlocking of the stance control orthosis during gait.

corresponding to the individual subject’s maximum knee flexion angle during the stance phase of running (average: 40.7° [4.7]°) in a supine position. Quadriceps muscle morphology was assessed from axial plane MR images of the thigh using a 3-D spoiled gradient-recalled echo protocol (repetition time: 10.1 ms

The lower quarter Y-Balance Test (YBT-LQ) is a clinical movement screening test aimed at assessing dynamic balance. The YBT-LQ utilizes unilateral stance while reaching in 3 reach directions: anterior, posteromedial, and posterolateral to assess both a composite reach score and asymmetry assessment

), there were a number of significant findings with regard to angular kinematics in the sagittal plane (no differences were observed for Ab/Ab or I/E motions). Figure  1 depicts significant increases in hip-flexion angle during NMT walking compared to OG for a period in late stance, as well as a period

adolescence (i.e., between 13 and 17 years old) through the analysis of COP signals. First of all, our results found different postural control between subjects of 13–14 years old and older adolescents. Furthermore, a critical change was found in sensory reweighting during the bipedal stance with manipulation
