Longus: Functional Movement?
Adduct the hip
Medially rotate hip & knee
Assist with hip flexion
Longus: Resisting the muscle?
Place one hand on their inner thigh and ask them to move their thigh toward the midline against your resistance. Apply gentle pressure to resist the adduction movement.
Brevis: Origin?
Inferior ramus of pubis
Brevis: Insertion?
Pectineal line and medial lip of linea aspera

Brevis: Functional Movement?
Adduct the hip
Medially rotate hip & knee
Assist with hip flexion
Brevis: Resisting the muscle?
Place one hand on their inner thigh and ask them to move their thigh toward the midline against your resistance. Apply gentle pressure to resist the adduction movement.
Pectineus: Origin?

Pectineus: Insertion?
Pectineal line of femur
Pectineus: Nerve?
Femoral & Obturator nerve L2 - L4
Pectineus: Bony Landmarks & Ligaments?
Femur, Pubis, ischium, linea aspera
Pectineus: Functional Movement?
Adduct the hip
Medially rotate hip & knee
Assist with hip flexion
Pectineus: Resisting the muscle?
- Resisted hip adduction: Stand beside the patient. Place one hand on their inner thigh and ask them to bring their leg toward the midline against your resistance.
- Resisted hip flexion: With the patient lying on their back, place one hand above their knee and resist as they try to lift their leg upward against your resistance
Gracilis: Origin?
Inferior ramus of pubis
Gracilis: Insertion?
Proximal, medial shaft of tibia at pes anserinus
Gracilis: Nerve?
Obturator nerve L2 - L4
Gracilis: Bony Landmarks & Ligaments?
Femur, Pubis, ischium, linea aspera
Gracilis: Functional Movement?
Flex the knee
Gracilis: Resisting the muscle?
- Resisted hip adduction: Stand beside the patient. Place one hand on their inner thigh and ask them to bring their leg toward the midline against your resistance.
- Resisted knee flexion: With the patient lying on their back, place one hand above their ankle and resist as they try to bend their knee against your resistance.
Sartorius: Origin?
Anterior superior iliac spine
Sartorius: Insertion?
Proximal part of the medial surface of tibia at pes anserinus
Sartorius: Nerve?
Femoral nerve (L2-L4)

Sartorius: Functional Movement?
Flex the hip
Laterally rotate
Abduct the hip
Flex the knee
Medially rotate the flexed knee (T/F joint)
Sartorius: Resisting the muscle?
Stand beside the patient. Place one hand on their thigh and ask them to lift their leg out to the side against your resistance. Apply gentle pressure to resist the abduction movement.
Tensor fascia latae: Origin?
Iliac crest
Posterior to ASIS
Tensor fascia latae: Insertion?
