Short leg (SLW) and patellar tendon bearing walkers (PTBW) are orthotic appliances† which have been recently designed as alterna­ tive devices to traditional plaster cast immobili­ zation. The indications for use of lower leg walkers include severe ankle sprains, and ankle and foot fractures. Orthopedic walkers are con­ venient to use, lightweight, and removable to perform joint range of motion...

The aim of the study was to investigate the influence of karate fights on Achilles tendon stiffness in karate competitors. Eleven male karate fighters participated in the present study. A handheld MyotonPRO device (MyotonPRO, Myoton Ltd, Estonia) was applied to measure Achilles tendon stiffness in karate fighters. The Achilles tendon was tested 5 cm above the tuber calcanei. Stiffness measureme...

CONTEXT Fatigue appears to influence musculoskeletal injury rates during athletic activities, but whether males and females respond differently to fatigue is unknown. OBJECTIVE To determine the influence of fatigue on vertical leg stiffness (K (VERT)) and muscle activation and joint movement strategies and whether healthy males and females respond similarly to fatigue. DESIGN Repeated-measu...

Two popular methods of assessing lower body musculotendinous stiffness include the hopping and oscillation tests. The disparity and paucity of reliability data prompted this investigation into leg musculotendinous stiffness (Kleg) and ankle musculotendinous stiffness (Kank) measures. Kleg and Kank were assessed on three separate occasions in 20 female subjects. Kleg was determined using bilater...

One approach in the field of legged locomotion is to use theoretical models and analysis to provide basic knowledge [1]. One particular group of these models with rotary hip torque and radial leg damping has demonstrated a greater degree of robust stability and biological relevance. The previously developed Clock Torqued Spring-Loaded Inverted Pendulum [3] and Torque-Actuated Dissipative Spring...
