| L/R THIGH | On line between greater trochanter and knee marker, belowe hand | |
| Most prominent point of medial femoral epicondyle | ||
| L/R KNEE | On knee joint center line | |
| Most prominent point of medial malleolus | ||
| L/R TIB | Approximately midway on line between knee and ankle markers | |
| Most medially prominent point of 1 metatarsal head | ||
| L/R TOE | Between and 10 mm proximal to 2 and 3 metatarsla heads | |
