2.3 Tips for Point Location
2.3.2 Patient Positioning and Body
Movements
To locate certain points, it can be very helpful to ask the patient
to assume a particular position or to perform a specific move-
ment.
Examples:
For locating points on the Pchannel on the forearm, ask the
patient to tightly press the thumb and little finger together.
This will make the tendons more visible (Fig. 2.6)
‘Tiger mouth grip’ as location help for LU-7and L.I.-6
(Fig. 2.7)
For locating L.I.-4, ask the patient to press his/her thumb and
index finger together. A muscle bulge will form; L.I.-4 is
located on its highest point (Fig. 2.8).
When turning the wrist joint from a pronated to a half-
supinated position, the palpating finger will glide into a bony
cleft just proximal to the styloid process of the ulna (S.I.-6,
fig 2.9).
As the palpating finger glides along the skin, the skin bulge
forming in front of it will ‘arrest’ the finger at the point to be
located. This method is very useful for quick location of cer-
tain points such as T.B.-5or P-6(Fig. 2.10).
