Calculating the scores for each of the BASMI

Table Two

	Mild 0	Moderate 1	Severe 2
Cervical rotation (Mean of L & R) Tragus to wall (Mean of L & R) Lumbar side flexion (Mean of L & R)	> 70 degrees < 15cm > 10cm	20 –70 degrees 15 – 30 cm 5 – 10 cm	< 20 degrees > 30 cm < 5 cm
Lumbar flexion (modified schobers) Intermalleolar distance	> 4 cm > 100cm	2 – 4 cm 70 – 100 cm	< 2 cm < 70 cm

Add the 0, 1, 2 scores for each of the five measurements using the table above (the mean for cervical spine rotation counting as one score and similarly for tragus to wall & lumbar spine side flexion). This will provide you with a figure out of 10. This is the BASMI score. The higher the BASMI score the more severe the patient’s limitation of movement due to their AS.

For cervical spine rotation, tragus to wall and lumbar spine flexion, take the mean of the left and right measurements. Add together the scores for each measurement. This will provide you with a figure out of 50. Divide this by 5 to give you the BASMI score. The higher the BASMI score the more severe the patient’s limitation of movement due to their AS.
