Origin
|
External surface of ilium between iliac crest and posterior gluteal line dorsally, and anterior gluteal line ventrally, gluteal aponeurosis. | |
|
Insertion
|
Oblique ridge on lateral surface of greater trochanter
of femur.

|
- location
|
Electrodes need to be placed at 50% on the line
from the crista iliaca to the trochanter.
|
|
|
- orientation
|
In the direction of the line from the crista iliaca
to the trochanter.
|
|
|
- fixation on the skin
|
(Double sided) tape / rings or elastic band.
|
