Question

These problem are based on a patient standing on one limb. For each of the problem , do the following The abductor muscles are assumed to absorb the entire adducting torque produced by the body weight on the hip joint of the stance leg. The figure on the right is the free body diagram for Problem. Problems: 1. Patient standing on one leg (Trendelenburg Test). 2. Patient carries one suitcase (25 kg 250 N) in the hand opposite the stance leg (moment arm = 0.31 m). 3. Patient carries n suitcase in each hand (moment arm in hand on side of standing leg = 0.14 m).

Explanation / Answer

torque=moment arm*force

=0.05+0.10 * 700

105Nm

force=mg sin theta

=700 sin 70=657.7848 newtons

Fnet=700-657.78=42.22 N
