✔✔How do you strengthen the longus colli? - ✔✔Tri-flex
,✔✔Only portion of lower crossed syndrome you wouldn't use Williams exercises on? -
✔✔Hip Extension...Williams are flexion so use McKenzie

THESE
Iliopsoas : perform hip extension (McKenzie)
Rectus Femoris : perform hip extension (McKenzie)
TFL : perform ADDuction
Adductor Group: perform ABduction
Erector spinae: perform flexion
Gastroc: can't isolate because crosses 2 joints
Soleus: can be isolated by flexing the knee
✔✔What are the four main postural issues associated with lower crossed syndrome? -
✔✔Anterior rotation of the pelvis (stretch iliopsoas)
Increased lumbar lordosis (Williams flexion)
Hips in flexion (stretch iliopsoas- McKenzie)
Knees may be hyperextended (genu recuvatum)
✔✔Action of the Iliopsoas - ✔✔Flexes hip joint
✔✔Action of the Rectus Femoris - ✔✔Flexes the hip joint
Quadriceps extends the knee joint

✔✔Action of erector spinae - ✔✔Extension of vertebral column
✔✔Action of gastrocnemius - ✔✔Plantar flexes ankle and assists in knee flexion
✔✔Action of soleus - ✔✔Plantar flexes ankle
✔✔Weak/Inhibited muscles in lower crossed syndrome - ✔✔STRENGTHEN THESE
(resistance against action)
Rectus Abdominis : crunches (williams)
Oblique : crunches (williams)
