Which of the following best describes the movement called circumduction at the shoulder joint?

Accepted Answer

Movement of the arm in a cone-shaped pattern combining flexion, extension, abduction, and adduction

Question 19

Which of the following equations correctly calculates the range of motion ($$ROM) of a $$joint if the initial angle is $$\$$theta_1$$ and the final angle is $$\$$theta_2$$?

Accepted Answer
