Brent's case study

Movements required for phase 1 of Brent’s task + Plane and axis:

• Flexion at hip - sagittal plane, frontal axis

• Abduction at hip - frontal plane, sagittal axis

• Flexion at knee - sagittal plane, frontal axis

• Dorsi-flexion at ankle - sagittal plane, frontal axis

Movements required for phase 2 of Brent’s task + Plane and axis:

• Extension at the hip - sagittal plane, frontal axis

• Adduction at hip - frontal plane, sagittal axis

• Extension at knee - sagittal plane, frontal axis

• Plantar-fexion at ankle - sagittal plane, frontal axis

Prime movers for hip flexion + origin and insertion:

Iliacus:

• Origin: iliac fossa

• Insertion: lesser trochanter of the femur

Psoas major:

• Origin: posterior abdominal wall and transverse processes

• Insertion: lesser trochanter of the femur

Prime movers for hip abduction + origin and insertion:

Gluteus medius and gluteus minimus:

• Origin: External surface of the ilium

• Insertion: greater trochanter of the femur

Prime movers for knee flexion + origin and insertion:

• Common origin (except biceps femoris short head): Ischial tuberosity

Biceps femoris:

• Short head origin: Linear aspera and lateral supracondylar ridge of the femur

• Common insertion: Head of fibula

Semimembranosus and semitendinosus:

• Insertion: medial tibial condyle

Prime movers for dorsiflexion + origin and insertion:

Tibialis anterior:

• Origin: Lateral condyle and surface of the tibia and the interosseous membrane

• Insertion: Medial cuneiform bone and base of first metatarsal

Prime movers for hip extension + origin and insertion:

Gluteus maximus

• Origin: posterior gluteal line, sacrum, coccyx

• Insertion: iliotibial tract and gluteal tuberosity

Extra: iliotibial tract is a thick connective band down lateral aspect of thigh

Prime movers for hip adduction + origin and insertion:

Adductor magnus:

• Origin: ischiopubic ramus and ischial tuberosity

• Insertion: Linear aspera and adductor tubercle

Adductor longus and Adductor brevis:

• Origin: body of the pubis

• Insertion: Linear aspera

Prime movers for knee extension + origin and insertion:

• Common insertion: Tibial tuberosity via patella ligament and quadriceps tendon

Rectus femoris:

• Long head origin: Anterior inferior iliac spine

• Short origin: ilium superior to the acetabulum

Vastus lateralis and medialis:

• Origin: intertrochanteric line and corresponding lips of the linear aspera

Vastus intermedius:

• Origin: Anterior and lateral surface of the femur

Prime movers for plantarflexion + origin and insertion:

Gastrocnemius:

• Origin: Medial and lateral supracondylar ridge of the femur

• Insertion: Calcaneus via achilles tendon

Soleus:

• Posterior aspect of the tibia and fibula

• Insertion: Calcaneus via achilles tendon
