Leg Length Discrepancy of Hemicoxarthrosis.
Rigakuryoho Kagaku, 1997 片側性の変形性股関節症患者の脚長差について，最適な補高を検討することを目的とした。3cm以上の脚長差を有する片側性変形性股関節症患者4名（術前患者2名，術後患者2名）を対象とし，SMDでの脚長差，立位で重心位置が最も中心に近い補高の高さ（以下，立位での最適補高），歩行時に被検者が主観的に最適と思われる補高の高さ（以下，主観的最適補高）の関係について比較検討した。その結果，立位での最適補高は，全例SMDでの脚長差よりも低い値であった。主観的最適補高は1例を除き，SMDでの脚長差と立位での最適補高の中間の値であった。また，それぞれの補高時の脚長差を見ると，立位での最適補高時は平均1.5cm，主観的最適補高時は平均0.63cmであった。今回の結果から ...

Asymmetry in Skipping Enhances Viability Against Control Input Noise
Advanced Robotics Research, EarlyView.Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Radiographic parameters improve lower extremity prosthetic alignment
Journal of Children's Orthopaedics, 2013 Purpose The goal of prosthetic fitting is to provide comfort and functionality to the patient. It is thought that incorporating the use of standing anterior–posterior long leg radiographs (LLR) into the fitting of lower extremity prostheses will provide ...

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

, 2007 The Ilizarov technique has been used to treat severe limb length discrepancy and short stature. However, complications of this treatment are frequent. Between 1984 and 2001, 57 patients (94 tibias) had an Ilizarov procedure for limb lengthening.

Advanced Robotics Research, EarlyView.This study explores how information processing is distributed between brains and bodies through a codesign approach. Using the “backpropagation through soft body” framework, brain–body coupling agents are developed and analyzed across several tasks in which output is generated through the agents’ physical dynamics.
