Which test focuses on maintaining neutral spine during progressive lower limb movements?

• A. Sahrmann core stability test
• B. Apley's scratch test
• C. Kendall test
• D. Ely test

Answer: (A)

The main concept being tested is neuromuscular control of the trunk to keep the spine in a neutral position while the legs move through progressively challenging tasks. In the Sahrmann core stability test, a person performs a sequence of lower-limb movements with the spine and pelvis held in a neutral alignment, and the difficulty increases step by step. This setup specifically challenges the deep core muscles, like the transverse abdominis and multifidus, to stabilize the trunk during limb motion. A person who can maintain neutral spine through the progression demonstrates better core stability and trunk control, which is important for safe movement and load transfer in daily activities. The other assessments focus on different things: the shoulder-rotation and reach test checks shoulder girdle mobility, not trunk stability during leg movements; and the tests for muscle length or flexibility (such as the hip flexors or quadriceps) evaluate tissue length rather than how well the core can stabilize the spine during progressive limb tasks.
