Calcaneal pitch is an angle of the calcaneus and the inferior aspect of the foot, with different sources giving different reference points. The first line making up the angle is defined as either: The calcaneal inclination axis, extending from the calcaneus by the inferior portion of the calcaneocuboid joint to the inferior border of the ...
The BRI models the human body shape as an ellipse (an oval), with the intent to relate body girth with height to determine body roundness. A simple tape measure suffices to obtain waist circumference and height. [1] [2] Waist circumference and height can be in any unit of length, as long as they both use the same one. [1] [3
Fiber length is also a key variable in muscle anatomy. Fiber length is the product of both the number of sarcomeres in series in the fiber and their individual lengths. As a fiber changes length, the individual sarcomeres shorten or lengthen, but the total number does not change (except on long timescales following exercise and conditioning).
Gait analysis is the systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. [1]
The foot structures are divided into segments from proximal to distal and are grouped according to similarity in shape, dimension and function. In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. The hindfoot is the most proximal and posterior portion of the foot. [22]
Loss of radial inclination is associated with loss of grip strength. [5] Radial length - It is the vertical distance in millimetres between a line tangential to the articular surface of the ulna and a tangential line drawn at the most distal point of radius (radial styloid). Shortening of radial length more than 4mm is associated with wrist ...
Having a constant diameter, measured at varying angles around the shape, is often considered to be a simple measurement of roundness.This is misleading. [3]Although constant diameter is a necessary condition for roundness, it is not a sufficient condition for roundness: shapes exist that have constant diameter but are far from round.
Allometry is often expressed in terms of a scaling exponent based on body mass, or body length (snout–vent length, total length, etc.). A perfectly allometrically scaling organism would see all volume-based properties change proportionally to the body mass, all surface area-based properties change with mass to the power of 2/3, and all length ...
