Cervical Flexion Normal ROM
60
Cervical Rotation Normal ROM
80
Cervical Lateral Flexion Normal ROM
45
spinous process
attachment for muscles and ligaments
transverse process
attachment point for ribs, muscles and ligaments
vertebral foramen
spinal cord passes through
intervertebral joint
symphysis joint, body/disc/body
Facet Joint
gliding joint, limit ROM, assist in load bearing/compressive forces
Motion Segment
functional unit of spine, two adjacent vertebrae and all associated soft tissue
Cervical Vertebrae features
smaller body, transverse foramen, bifid spinous process, greatest ROM
SCM Function
PM flexion and hyperextension, contrlateral rotation
Scalene Function
neck flexion, PM ipsilateral rotation and lateral flexion
Splenius Capitis/Cervicis
PM Neck extension, PM ipsilateral rotation and lateral flexion
T-Spine
middle sized bodies/foramen, greatest stability
Costovertebral Joint
gliding joint, move ribs during breathing
Lumbar Vertebrae
largest body, small foramen
Stabilization Muscles
Transverse, IO, Multifidus, Deep erectors
Movement Muscles
Rectus, QL, EO, Superficial erector
Cervical Plane of motion
Trasnverse
Thoracic Plane of motion
Frontal
Lumbar Plane of motion
Sagittal
Stress placed on spine flexion
Disc: Anterior compression, posterior tension
Ligament: PLL and Flavum stretched
Joint: Intervertebral
Stress placed on spine extension
Disc: Anterior tension, posterior compression
Ligament: ALL stretched
Joint: facet
Stress on spine Lateral Flexion
Disc: Ipsilateral compressed, contralateral tension
Rotation
Shear
Pelvic Girdle
Lumbosacral, SI (Gliding), Pubic symphysis
Anterior Pelvic Tilt
Force couple between ES and Hip Flexors, ASIS over Pubis
Posterior Pelvic Tilt
Pubis in front of ASIS, force couple between abs and glutes
Lateral tilt
Lower ASIS on non supported/hip drop side
Lateral flexion to supported/hip hike side
Rotation
pelvis rotates and trunk rotates opposite side
Muscle Control Anterior Pelvic Tilt
spinal erectors/hip flexors
Muscle control posterior pelvic tilt
Abs and hip extensors
Muscle control lateral tilt
Unsupported side: ES and QL
Supported Side: Glute medius/minimus
