During Sahrmann test stage 5, what is the key action?

• A. Both legs are fully extended and lowered toward the floor while maintaining neutral spine and constant pressure.
• B. One leg remains extended while the other flexes.
• C. Both legs are raised toward the ceiling.
• D. Pressure is released and legs stay on the table.

Answer: (A)

Stage five of the Sahrmann leg-lowering stability task is about controlling the trunk while the legs are moved with maximum challenge. The key action is to keep both legs extended and slowly lower them toward the floor while maintaining a neutral spine and a constant brace of the abdominal muscles (intra-abdominal pressure) throughout the movement. This demands precise coordination of the deep stabilizers to prevent the spine from flexing or the pelvis from tilting, showing that lumbopelvic stability is preserved under a demanding leg-lowering load. If neutral spine control or the abdominal brace is lost, it indicates limited stability. The other described actions don’t impose the same level of trunk control and bracing required at this stage.
