Study Notes
External Forces in Gait Analysis
- External forces involved in gait analysis include gravity, ground reaction forces, and frictional forces.
Line of Gravity (LOG)
- The line of gravity (LOG) represents a vertical line passing through the body's center of mass.
Gravitational Torque
- A gravitational torque is created around a joint axis when the line of gravity (LOG) does not pass through the joint axis.
Components Assisting Muscles
- Bones, ligaments, and joint capsules are components that primarily assist muscles by resisting, transmitting, and absorbing forces.
Line of Gravity (LOG) and Joint Axis
- If the line of gravity (LOG) passes directly through a joint axis, no gravitational torque is created around that joint axis, and muscles do not need to generate a torque to balance the gravity.
