(Image 1) Palpate and mark S1 and T12
Step 3: Demonstrate and have patients perform flexion and extension movements. Emphasize the importance of smooth steady movements that go to end range. Check that both contact points remain on the sacrum and the pivot point remains on S1 during movements.

Step 4: Have the patient stand erect. Feet should be shoulder width apart. Place the moveable arm on T12 and record the reading on the sliding scale. This reading is the distace between S1 and T12 and can be used to position the arm during future measurements to assure that the same segment of spine is measured. The typical reading for an adult is 15 cm.
Step 5: With the arm tip on T12 record the initiall reading in degrees from the outer protracter scale. Remove the arm tip from T12 and place a finger securely on T12. Have the patient slowly bend forward trying to lay the palms on the floor. Replace the armtip on T12 and take the reading.

Step 6: Repeat step 5. If the reading is within 3 degrees, record the higher reading. If not, repeat.
Step 7: EXTENSION MEASUREMENTS Check that the patient is standing erect. Have the patient put their hands on their shoulders. Place the armtip on T12 and record the initial reading from the outer scale. Remove the armtip and have the patient extend backward (see image 4). Provide the necessary support to prevent the patient from falling backward. Replace the armtip on T12 and record the full extension reading. Subtract the full extension reading from the initial reading to obtain true flexion. A typical value is 12 degrees.

Step 8: PELVIC TILT MEASUREMENT Remove the arm. Have the patient stand erect. Move the dial until the yellow vial’s bubble is between the two lines (see Image 5). Record the reading from the INNER scale.

Frequently Asked Questions
What is the BROM back range of motion?
BROM Back Range of Motion (BROM) is a specialized tool that accurately measures how the spine moves—covering flexion, extension, rotation, lateral flexion, and pelvic tilt. It uses inclinometers and magnets for precise measurements, reducing errors common in other tools. BROM allows assessment of lumbar rotation, a key movement in the lower back. It offers an innovative way to understand and monitor the flexibility and mobility of the spine.
Is lumbar rotation good?
Yes, lumbar rotation within a normal range is essential for mobility and daily activities.
Why is range of motion used?
Range of motion (ROM) is crucial to assess joint and muscle health, providing insights into flexibility, mobility, and overall functional ability. It helps diagnose conditions, monitor progress during rehabilitation, guide treatment plans, and tailor exercises.
What is normal range of motion for back?
A normal back's range of motion includes bending forward (flexion) about 50-90 degrees, straightening backward (extension) 20-35 degrees, and twisting (rotation) 30-35 degrees to each side. Additionally, bending sideways (lateral flexion) is usually 25-30 degrees to each side.
