Describe the biomechanics of human locomotion. Discuss examples of how biomechanical models can aid recovery of locomotion in patient groups and enhance locomotion in athletes. Flashcards
What systems does human locomotion involve?
The Skeletal system the muscular system,(generates the power needed to move the body), and the nervous system, (ensures coordination and control of these movements)
What is the Stance phase?
when the foot is in contact with the ground and carries body weight, this includes initial contact, midstance and propulsion
What is the purpose of the stance phase
to provide a stable base for the body and to absorb shock
What is the swing phase?
what the foot is not in contact with the ground and involved in moving the body forward; includes initial swing, midswing, and terminal swing
What is the purpose of the swing phase
It prepares the foot for the next stance phase and advances the body
What role does the skeletal system play?
It provides the rigid structure necessary for movement
What role do bones play in locomotion
They act as levers and the joints act as fulcrums, facilitating movement
What role do muscles play in locomotion?
The muscles generate tension needed to move the bones at the joints
What role does the nervous system play in locomotion?
Particularly the motor cortex and cerebellum, coordinates these movements ensuring that they are smooth and purposeful
What can biomechanical models be used for?
To analyze gait patterns, calculate joint forces and assess muscle activity. They can help in identifying abnormalities in gait patterns which can be used to develop personalized rehab programs
Give an example of a rehab program
A patient recovering from stroke often experiences difficulties with walking due to muscle weakness and coordination problems, through analyzing their gait they can target growth of specific muscles.
Is it useful for an althlete?
Yes, by understanding the specifics they can optimize performance and prevent injuries.
give an example of an athlete program?
A runner using biomechanical analysis to identify inefficiencies in their stride, like overpronation or underpronation, running more efficiently will reduce the risk of injury.
