Cards in this deck (14)
- 1What is biomechanicsthe application of general human law on human motion
- 2what is human locomotionthe movement of the human body and its segments from one place to another
- 3What is human walking?it's a very complicated procedure, as it involves a three dimensional motion of a multiple linkage system which is controlled by the central nervous system
- 4What is gait analysisit's the quantitative description of the mechanical aspects of walking; relating the kinetic to kinematic data, and it's the foundation for understanding human walking
- 5What is a synovial joint?it's where two or more bones are joined together and compete any other mechanic joint
- 6What is the center of mass?the point where the mass of the body would be located if all the mass were concentrated in one infinantly small volume
- 7What factor affect the type of the mechanical joint?- the human joint itself (H,K,A)
- the aims of the model
- how accurate the model should be - 8What affects the number of segments in a model?- aims of the model
- how accurate the results should be
- the studies part - 9what is a gait cycle?the period when the foot first contacts the floor and proceeds through the process of walking till the instance of the same foot contacting the floor again
- 10what is a stride?the distance achieved during one gait cycle
- 11what is stance phase?when the foot is in contact (totally or partially) with the ground, it's about 60% of GC
- 12what is kinetics?the science that studies the act of force and its result on stopping or changing movement
- 13what is kinematics?the science that studies the movement and its parameters such as linear and angular velocity, linear and angular displacement and and acceleration
- 14what are gait parameters?1- durations of stance and swing phases
2- three dimensional positions of joints centers
3- three dimensional angles of segments in space
4- trunk ex/fle, tilt and rotation
5- angle of the arms movement regarding the gait and the trunk movement
