Ankle-hip joint trade-off in normal gait: Exploring the kinematic influence of the medial longitudinal arch of the foot.

Background: In human gait, leg progression into the swing phase involves two primary strategies: ankle plantar flexion and hip flexion. These strategies are believed to exhibit a trade-off relationship; however, it is unclear whether this relationship holds for normal gait and the role of the medial longitudinal arch (MLA) in shaping these strategies.

Research Questions: Does a trade-off relationship exist between ankle plantar flexion and hip flexion strategies during normal gait in young healthy adults? Do the kinematics of MLA during gait influence the strategies during leg progression into the swing phase?

Methods: Data from 36 young healthy adults were analyzed.

Covalent Bonds van der Waals Forces: A Picture in Thermal Conduction of Organic Materials.

We present a direct comparison of the heat transport properties between the state in which the constituent molecules are assembled by intermolecular forces and the one in which they are covalently bonded, in a molecular system with identical constituent elements and masses, as well as a nearly identical structure and density. This comparison leading to an essential understanding of thermal conduction in organic materials is made possible by the unique compound found by Wudl et al., which exhibits a single-crystal-to-single-crystal topochemical polymerization with a yield of >99%, in combination with microtemperature wave analysis (TWA), which allows accurate measurements of the thermal diffusivity of small single crystals.

Kinematics of the anterior interval in individuals with knee osteoarthritis.

[Purpose] Abnormal anterior interval kinematics may be associated with knee pain and loss of knee motion. We investigated the anterior interval kinematics during passive knee extension in individuals with knee osteoarthritis (OA). [Participants and Methods] The anterior interval space was evaluated in 13 healthy knees (healthy group) and 11 knees with OA (knee OA group) at 30° and 15° knee flexion using ultrasonography.
