Reference line design: In order to describe the mediolateral and superioinferior relationship between NEPs and the bony landmarks, the greater trochanter of femur (A), lateral epicondyle of femur (B), and pubic tubercle (C) were chosen as bony landmarks for measurement.
Based on the results of this study, we suggest that during the practice of chemical neurolysis treatment to thigh adductor muscles spasticity, one could measure on body surface the length between greater trochanter of femur and pubic tubercle (H line), and the length from greater trochanter of femur to lateral epicondyle of femur (L line).
