Purpose: There is a scarcity of information on the long term adaptations in lower limb biomechanics during game specific movements after an anterior cruciate ligament (ACL) reconstruction. Particularly, variables such as knee abduction moments and transverse plane knee motion have not been studied during a game specific landing and cutting task after ACL reconstruction. The purpose of this stud...

Manually landing an unmanned aerial vehicle presents unique challenges since unmanned vehicle pilots require extensive training to become proficient in the landing task. Operators must therefore choose between a pilot controlling the vehicle from a ground station, or procurement of an automatic landing system. Although several autoland controllers exist for small or micro unmanned vehicles and ...

Core stability training (CST) has increased in popularity among athletes and the general fitness population despite limited evidence CST programmes alone lead to improved athletic performance. In female athletes, neuromuscular training combining balance training and trunk and hip/pelvis dominant CST is suggested to reduce injury risk, and specifically peak vertical ground reaction forces (vGRF)...

Planetary exploration missions include an entry-descent-landing phase, where the spacecraft descends on a relatively steep trajectory to the surface. In order to minimize the loads during landing, a deceleration system is employed, consisting essentially of some or a combination of parachutes, retrorockets and airbags. Due to the communication round-trip delay time between spacecraft and ground...

BACKGROUND Obstacle crossing is impaired in people following stroke. It is not known whether people with stroke who fail an obstacle crossing task have more falls or whether the gait adjustments used to cross an obstacle differ from those used by people who pass the task. OBJECTIVE The purposes of this study were (1) to identify whether a group of people with stroke who failed an obstacle cro...

Background and Aims: The accurate mechanisms of ankle instability cannot be assessed in the absence of reliable knowledge about ground reaction force (GRF) variables. The purpose of this study was to evaluate the test-retest reliability of GRF variables during forward and lateral jump-landing in volleyball players with functional ankle instability (FAI). Methods: Eighteen professional volle...
