Human Locomotion
Objectives:
#1 To provide students with an understanding of the biomechanical
principles that form the basis for human locomotion
#2 To provide students with an understanding of the kinematic,
temporal/spatial, kinetic, and electromyographic
characteristics of normal human locomotion.
#3 To provide students with a general overview of the influence on
gait of selected pathological conditions.
#4 To provide students with an understanding of the technical
procedures involved in the analysis of human gait.

“About the Movement
of Animals”

Instruction concerning a dislocation of a vertebra of the neck:
“if you examine a man having a dislocation of the a vertebra of
his neck, should you find him unconscious of his arms and legs
on account of it......then you should say an ailment which
cannot be treated “
Edwin Smith Papyrus (1800) –
Egyptian circa 600 BC
Antiquity - 650 B.C. - 200 A.D.
Relevance to the study of Locomotion
• Separation of Knowledge and Myth
• Mechanical and Mathematical Paradigms
developed
• Anatomical Paradigms developed
• First Biomechanical Analysis of Human
Movement
The Middle Ages - 200 A.D. - 1450 A.D.

Significant People/Events
• Spiritualism diminished scientific inquiry
• St. Augustine - “the only type of knowledge
to be desired was the knowledge of God
and the soul”
• Arab scholars saved the work of the
Antiquity period by translating the works
into Arabic
The Middle Ages - 200 A.D. - 1450 A.D
Relevance to the Study of Locomotion
• Interest in anatomy, physiology, and
locomotion discouraged.
• Greek and Roman Art depiction of
human movement remained
The Renaissance - 1450 A.D. - 1600 A.D.

Significant People/Events
• Individual genius flourished
• Leonardo da Vinci - artist, scientist;
anatomical studies of bone, muscle,
nerve through dissection. He
described the mechanics of the
body during standing, walking up
and downhill, rising from a sitting
position, jumping, and human gait.
• Versalius - described muscle
function and related to movement,
advocated human dissection
The Renaissance - 1450 A.D. - 1600 A.D.
Borelli –
Estimated the center of mass of nude
men by having them stretch out on a
rigid platform supported on a knife
edge. The platform was then
repositioned until is balanced, thereby
indicating a location corresponding to
the center of mass for the entire body.
The Renaissance - 1450 A.D.- 1600 A.D.
Relevance to the Study of Locomotion
• Scientific study revived
• Foundations of modern anatomy and
physiology
• Movement and muscle studied as
connective entities
The Scientific Revolution - 1600 A.D. - 1730 A.D.


• Experimentation - the
basis of the scientific
method
• Galileo - Studied human
jumping, horse gait,
structure of bone
• Harvey - described blood
flow through heart

locomotion…..economy of
movement
