Praxis 5857 Practice Question
Hyperextension of the lumbar spine occurs when a person
Correct Answer: B
Rationale: Hyperextension of the lumbar spine occurs when bending backward, as this motion increases the angle between the torso and thighs, extending the spine beyond its neutral position.
Option A, bending forward, results in flexion of the lumbar spine, decreasing the angle and not causing hyperextension. Options C and D, bending or twisting to the left or right, involve lateral movements that do not extend the spine backward, thus they do not lead to hyperextension. Understanding these movements is crucial for maintaining spinal health and preventing injury.
