5 Questions
What factors affect the loading on the hip joint in different situations?
Muscle tension, body weight, and external forces
How can you calculate the joint reaction force (JRF) at the hip?
By considering the weight distribution and external forces acting on the hip joint
What is the load on each hip joint during double (bilateral) stance in the frontal plane?
1/3 of the body weight
In an individual weighing 90 kg, what is the compressive force acting on each femoral head during double (bilateral) stance?
30 kg
Why is very little muscle activity required to maintain an erect position during upright standing posture?
Because gravity acts equally on both sides of the body and the line of gravity falls posterior to the axis of the hip joint
