BACKGROUND The aim of this study was to examine the effect of anxiety about falling on selected physiological parameters on the lead (LC) and top-rope climbing (TRC) methods. For this purpose the physical differences between the two methods have been eliminated and the effect of only the anxiety about falling on the physiological parameters has been studied. METHODS A total of 26 intermediate...

To reach adult habitats, juveniles of three species of Hawaiian gobies (fishes under 3 cm long) climb waterfalls up to 350 m high, over 10 000 times their body length. The demands of moving through such an extreme environment could constrain the range of viable locomotor mechanisms that these fishes use. Previous qualitative observations indicated that Lentipes concolor and Awaous guamensis use...

We present a new manufacturing technology to produce multi-scale compliant feet for use with a novel climbing robot. Climbing robots for space exploration missions may allow scientists to explore environments too difficult for traditional wheeled designs. These climbing robot designs should be able to grasp or adhere to a variety of surface types at multiple angles in order to be effective. To ...

OBJECTIVE During the transitional phase (ambulatory to non-ambulatory), synergies characterize the evolution of Duchenne muscular dystrophy (DMD). This study was performed to describe and quantify compensatory movements while sitting down on/rising from the floor and climbing up/down steps. METHOD Eighty videos (5 children × 4 assessments × 4 tasks) were recorded quarterly in the year prior t...
