Purpose This study builds on knowledge of intimate partner violence (IPV) perpetration by examining theoretically important aspects of this crime within an Australian community sample. More specifically, the current study examines the relationship be

Here, we seek to determine how compliantly suspended loads could affect the dynamic stability of legged locomotion. We theoretically model the dynamic stability of a human carrying a load using a coupled spring-mass-damper model and an actuated sprin

Current literature describing the periacetabular osteotomy (PAO) is mostly limited to retrospective case series. Larger, prospective cohort studies are needed to provide better clinical evidence regarding this procedure. The goals of the current stud

Background The “rocking horse” phenomenon is considered the main cause of glenoid component loosening by eccentric loading of the glenoid rim. This study aimed to investigate the influence of increasing glenohumeral implant mismatch on bone-impla

Carrying loads with a compliant pole or backpack suspension can reduce the peak forces of the load acting on the body when the suspension natural frequency is tuned below the stepping frequency. Here we investigate a novel application for a load susp

Case: An extensive iliofemoral-popliteal deep venous thrombosis following arthroscopic anterior cruciate ligament reconstruction presented on the ninth postoperative day as the result of underlying May-Thurner syndrome. The patient was managed with t

Elasticity is an essential property of legged locomotion. Elastically suspending a load can increase the efficiency of locomotion and load carrying in biological systems and for human applications. Similarly, elastically suspended loads have the pote

Stabilizing arm mechanisms are used to support and position a load with minimal force from the user. Further, stabilizing arm mechanisms enable operators to stabilize the motion of the load while walking or running over variable terrain. Although exi

Carriage of heavy loads is common in developing countries and can impart large repetitive forces on the body that could lead to musculoskeletal fatigue and injury. Compliant bamboo poles have been used to carry heavy loads in Asia for generations and
