Pelvic Floor Muscles Support pelvic floor organs

Assist in urinary and fecal continence

Aid in sexual performance

Stabilize surrounding joints

What Muscles Determine The Position Of the Pelvis?

Quadriceps Hamstrings Psoas MajorQuadratus Lumborum

Tensor Fascia Latae

Rectus Abdominis Latissiums Dorsi Multifidus

AdductorsErector spinea

Quadratus Femoris

Gluteus maximus

Gluteus medius

Levator Ani

Page 22: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

IliopsoasThe most important pelvicMuscle that doesn’t attach

to the pelvis

It’s alignment determines the relationship of the upper

and lower body

Page 23: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Iliotibial Band

ITB and TFL extend, abduct, & laterally rotate the hip

Stabilizes the knee in extension and a bit of flexion

TFL shortens the ITB at the knee

Half of the torque required to hold us up when pelvis is well aligned/

90% of the torque when misaligned

Page 24: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Iliotibial Band

The ITB is not muscle and doesn’t forgive bad posture the way muscle does

Misalignment of the femurs affects the ITB As the bones shift forward pulling the ITB backwards

Stabilizes the hip while walking

It’s evolution has been geared towards running

Acts as a spring to aid in locomotion

Tensor Fasciae Latae

External Rotation

Adduction

Stabilizes the pelvis on the leg

Origin on the ischial tuberosity

Insertion on greater trochanter

Quadrilateral muscle

Tensor of the Outer Fascia

Tensor fasciae latae

Adductor longus

SartoriousRectus femoris

Tensor fasciae latae

Pectineus

Page 26: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Quadriceps

Rectus Femoris

Flexes the thigh at the hip

Only quadriceps muscle to connect to the pelvis

Hip flexor along with psoas and sartorious.

Weak when knee is extended

Gluteal Muscles

Gluteus Minimus Gluteus Medius Gluteus Maximus

Page 29: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Gluteus Maximus

Big bubble of a muscleBrought us up to stand w/ hamstringsExtends and externally rotates the leg

Connects into the IT BandTends to be overly engaged.

We are a tight assed people and we need to let go.

Abducts the thighTogether both halves abduct the

hip and stabilize the pelvis.

Hamstrings

Page 33: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Hamstrings

Biceps FemorisTwo heads: One on tuberosity,

one on pelvis.

Attachment on tuberosity extends the knee

The second head attached to the pelvisInvolves the muscle in hip flexion.

Page 34: The Hip & Socket...Gluteal Medius The front half helps to flex and internally rotate the hip. The back half helps to extend and externally rotate the hip. Abducts the thigh

Hamstrings

Semimembranosus

Extends the thigh at the hip

Medially rotates the leg if the knee is flexed

Adductors

5 adductors

Pull the leg towards the midline

Adductor magnus acts like a extensor and flexor as well as adductor

One of the holy trinity of muscle groups
