During human walking, the center of pressure under the foot progresses forward smoothly during each step, creating a wheel-like motion between the leg and the ground. This rolling motion might appear to aid walking economy, but the mechanisms that may lead to such a benefit are unclear, as the leg is not literally a wheel. We propose that there is indeed a benefit, but less from rolling than fr...

BACKGROUND Existing guidelines for optimal positioning of endotracheal tubes in neonates are based on scanty data and relate to measurements that are either non-linear or poorly reproducible in sick infants. Foot length can be measured simply and rapidly and is related to a number of external body measurements. OBJECTIVES To evaluate the relation of foot length to nasotracheal length in direc...

[Purpose] We developed socks which improve foot sensation and investigated their effect on the velocity and stride length of elderly women crossing obstacles. [Subjects] Ten community-dwelling, elderly women who could walk independently were recruited. [Methods] We measured velocity and stride length using the GAITRite system while the participants crossed obstacles under three conditions: bare...

BACKGROUND Foot dimension information on different user groups is important for footwear design and clinical applications. Foot dimension data collected using different measurement methods presents accuracy problems. This study compared the precision and accuracy of the 3D foot scanning method with conventional foot dimension measurement methods including the digital caliper, ink footprint and ...

In the present study an attempt has been made to reconstruct stature on the basis of hand and foot measurements among Kayastha Community of Bundelkhand region of India. A total of 223 Kayastha (100 males and 123 females) ranging in age 20 to 40 years were measured for the Stature, Hand length, Hand breadth, Foot length and Foot breadth by following the standard technique. Data demonstrates that...

Our understanding of how partial foot prostheses function stems from static force analyses, where assumptions about the location of the ground reaction force during terminal stance have been made. While such assumptions seemed reasonably based on an understanding of normal gait, they are often illogical based on what is observed clinically. As such, the aim of this work was to evaluate the beli...
