Thoracolumbar flexion ROM is assessed. Which option correctly describes the patient position and measurement method?

• A. Position: Standing; Stabilize: Stabilize the pelvis to limit Anterior pelvic tilting; Tape Measure: between spinous process of T1 and S2 vertebra; Procedure: measure distance between spinous processes in neutral. Ask the Pt to flex and re-measure. Find the difference between measurements indicates the amount of thoracolumbar flexion ROM
• B. Position: Standing; Stabilize: Stabilize pelvis to limit Posterior pelvic tilting; Tape Measure: between spinous process of T1 and S2 vertebra; Procedure: measure distance between spinous processes in neutral. Ask Pt to extend and re-measure.
• C. Position: Standing; Stabilize: Stabilize the pelvis to limit Posterior pelvic tilting; Tape Measure: between spinous process of T1 and S2 vertebra; Procedure: measure distance between spinous processes in neutral.
• D. Position: Standing; Stabilize: Stabilize pelvis to limit Anterior pelvic tilting; Tape Measure: between spinous process of T1 and S2 vertebra; Procedure: measure distance between spinous processes in neutral. Ask Pt to flex and re-measure.

Answer: (D)

The main idea here is to isolate thoracolumbar flexion by measuring how much the spine itself moves, without the pelvis skewing the result. To do this, have the patient stand and secure the pelvis so its movement won’t contribute to the change in length. Stabilizing to limit anterior tilting keeps the pelvis from tilting forward and adding extra spinal movement, allowing the measurement to reflect the thoracolumbar segment more accurately. Place a tape measure between the spinous processes from T1 to S2 and record the distance in neutral. Then ask the patient to flex forward and re-measure. The difference between the two distances represents the thoracolumbar flexion ROM. This approach uses the same landmarks (T1 to S2) and a repeatable neutral-to-flexion measurement, which is why it’s the best option. The other choices either suggest the wrong stabilization direction or movement (extending instead of flexing) or omit the re-measurement step, which would not correctly capture the ROM.
