Your patient is performing shoulder flexion from 0 to 180$\degree$ in a standing position with his elbow extended while holding a 5-pound weight in his hand. The torque imposed by the 5-pound weight is greatest at ______$\degree$.

Question

Quizplus · Accepted Answer

The torque imposed by the weight is greatest at 90 degrees because this is the point where the lever arm (distance from the weight to the axis of rotation, which in this case is the shoulder joint) is longest, maximizing the torque according to the formula torque = force x distance.
