3) You are helping a patient to strengthen their hip flexors. Your patient is performing a hip flexion exercise as illustrated below (assume knee in full extension). While he was standing, you measured the distance from the hip joint to the center of mass of the thigh, shank and foot to be 0.32, 0.68, and 0.98m. The masses of his thigh, shank, and foot are 15.6, 11.2, and 3.1kg. Calculate the amount of hip flexor muscle torque required to hold the leg isometrically at 35⁰. Foot, 0.98m from Hip Shank, 0.68m from Hip Thigh, 0.32m from Hip Hip Joint

Question

Transcribed Image Text:3) You are helping a patient to strengthen their hip flexors. Your patient is performing a hip flexion exercise as
illustrated below (assume knee in full extension). While he was standing, you measured the distance from the
hip joint to the center of mass of the thigh, shank and foot to be 0.32, 0.68, and 0.98m. The masses of his thigh,
shank, and foot are 15.6, 11.2, and 3.1kg. Calculate the amount of hip flexor muscle torque required to hold the
leg isometrically at 35°.
Foot, 0.98m from Hip
Shank, 0.68m from Hip
Thigh, 0.32m from Hip
Hip Joint
