Table 1

Description of the acupuncture points used in the study.

Point	Meridian	Assessment method
BL37	Urinary Bladder	8 cun vertical cranial direction from BL40
BL40	Urinary Bladder	Centre of the popliteal fossa (between the tendons of the biceps femoralis and the
		semitendinosus). Ultrasound localisation.
KI10	Kidney	Centre of the popliteal fossa (between the tendons of the semimembranosus and
		semitendinosus). Ultrasound localisation.
ST31	Stomach	Inferior to the AIIS, at the intersection with the sartorius. Ultrasound localization.
ST32	Stomach	11 cun caudal from ST31 or 6 cun cranial from external top of the patella, in the
		imaginary line that joins ST31 with the external portal of the knee (ST35)
ST33	Stomach	14 cun caudal from ST31 or 3 cun cranial from external top of the patella, in the
		imaginary line that joins ST31 with the external portal of the knee (ST35)
ST34	Stomach	15 cun caudal from ST31 or 2 cun cranial from external top of the patella, in the
		imaginary line that joins ST31 with the external portal of the knee (ST35)
SP10	Spleen	4 cun cranial (in a palpable depression of the vastus medialis)
SP11	Spleen	10 cun cranial (at the intersection between the sartorius and the vastus medialis)
GB31	Gall bladder	12 cun from the highest prominence of the greater trochanter in the caudal
		direction, on the midline of the outer thigh; when the patient is standing in the
		military position with hands close to sides, the point is at the tip of their middle
		finger
LR9	Liver	6 cun from the internal femorotibial joint line (intersection between the sartorius
		and the vastus medialis)
LR10	Liver	3 cun inferior to the superior border of the pubic symphysis (intersection
		between the Sartorius and the adductor longus)
