Posture Flashcards
normal posture assessment
neutral spine position natural lordotic state
muscles associated with postural control
erector spinae group + abdominals (balance pelvis) (work together), middle trapezius, rhomboids, upper trapezius, splenius capitus and cervicus, gasrocnesmius and soleus and tib posterior, Quadriceps, Gluteus maximus
the 4 major control components/structures associated with balance and postural control and each components/structure’s function.
Cerebellum
Vision
Vestibular
Proprioception
Vision
orient our bodies in our environment
Vestibular system
awareness and control of our body in motion for balance and control
provides awareness of center of gravity
Proprioceptive awareness
the body’s awareness
Receptive nerve impulses to body tells body what its doing
Cerebellum
unconscious control of movement & posture & is linked with vision vestibular and most importantly proprioception
Lock Knees
lumbar spine hyper extension hip extension thoracic spine increase kyphosis cervical spine inreased lordosis as a componsation for lumbar spine hyperlordosis
screw home mechanism go directly into valgus
femurs rotate in
major ligament that protects hyperextension of knee
anterior cruciate ligament
Stressed during lock knee
and colateral ligaments
Tibialis anterior
does not help with posture control
Gravity does it for you
Hamstrings too
and hip flexors
Forward flex posture
spinal stinosis
no Quads = Lock Knee
Hyper Extension
Weak Gluteus maximus
