Lecture Test 2 Flashcards
Lower Cross Syndrome
Tight Thoracolumbar Extensors, Weak Abdominals, Weak Glutes, Tight Iliposoas & Rectus Femoris
Common location for Vertebral Artery imingement?
C1 due to sharp medial turn
Atlanto-Occipital Joint Arthro
convex occipital condyles on concave superior facets
AO Osteo
convex occipital condyles on concave superior facets
AO Flexion limited by
Bony contact of dens and foramen magnum
AO Extension limited by
Compression of occiput on sub occipital muscles
Atlantoaxial Joint Artho
pivot joint between dens of C2 and anterior arch of C1/transv
AA Osteo
Flex/Ext, Lateral Flexion, ROTATION!
Intervertebral Joint Arthro
Sliding and tilting superior vertebra on intervertebral discs
Facet Joint Arthro
sliding of inferior facet of the vertebrae above and & SUP facet of the vertebrae below
Intervertebral and Facet Joint Osteo
Flex/Ext, Lat Flex, Rotation
Cervical Facet Orientation
45 degrees in frontal plane
Cervical Flexion ROM
Goni: 45
Inclino: 50
Cervical Lateral Flexion ROM
Goni: 45
Inclino: 45
Cervical Rotation ROM
Inclino: 80
Cervical Extension ROM
Goni: 45
Inclino: 60
Cervical Flexion limited by:
Interspinous ligament, Posterior Longitudinal Ligament, posterior part of annulus fibrosus, ligamentum flavum
Cervical Extension limited by:
Bony contact of facets, Anterior Longitudinal Ligament, anterior part of annulus fibrosus
Cervical Lateral Flexion limited by:
Intertransverse ligaments, vertebral process/bodies, lateral parts of annulus fibrosis
Cervical Rotation limited by:
Annulus Fibrosis
Facet joints limited by:
Synovial joint capsule/capsular ligaments
Upper Cross Syndrome
Inhibited Neck Flexors, Inhibited Rhomboids & Serratus Anterior, Tight Upper Trap & Levator Scapula, Tight Pecs
Thoracic Extension limited by:
Spinous Processes
Thoracic Flexion Arthro
superior vertebrae tilts ant, translates ant, facet joints: inferior facet of superior slides upward on superior facet of inferior
Thoracic Lateral Flexion Arthro
facet downslides on same side and up slides on contralateral
Thoracic Rotation Arthro
superior vertebrae rotates on inferior vertebrae…impact of inferior facet of sup vert on sup facet of inferior vert. on opposite side
Thoracic Flex/Ext Osteo
facets T1-T6 = frontal plane…limited flex and ext
Facet T6-T12 = more sagittal alignment… allows more flex/ext
Thoracic Lat Flex/Rotation Osteo
Ribs restrict in upper/middle thorax
Lumbar Flex Artho
inferior vertebral facet of superior body slides upwards
Lumbar Lat Flex Arthro
inferior vertebral facet on superior slides down towards lat flex, up on other
Lumbar Rot Arthro (left)
right inferior facet of superior body, impacts superior facet of inferior body
Lumbar Flex/Ext Osteo
facet joints in sag plan = more flexion/ext, limits lat flex and rotation
L5-S1 most flexion, little to no rot/lateral flexion
Lumbar Lat Flex/Rot Osteo
Upper L-spine more (L1-L2, L2-L3)
Trunk Flexion ROM
TM: 10cm
Inclino: 60
Trunk Extension ROM
Goni: 35
Inclino: 25 (L-spine)
Trunk Lateral Flexion ROM
TM: 22cm
Goni: 35
Inclino: 25 (L-spine)
Trunk Rotation ROM
Goni: 45
Inclino: 30 (T-spine)
Trunk Flexion Functional ROM: Sit to stand
35 Degrees
Trunk Flexion Functional ROM: Picking up item from floor
60 degrees
TMJ Osteo
depression (mouth opening), elevation (mouth closing), protrusion, retraction/retrusion, and lateral deviation
TMJ Depression/Elevation Arthro
sagittal plane; condylar rotation combined with sliding of the condyles on the inferior surface of the discs
TMJ Protrusion/Retrusion Arthro
bilateral condyles and discs translate together along temporal articular eminences; upper joint; no rotation (more of a glide)
TMJ Lateral Deviation Arthro
one mandibular condyle and disc slide inferior, anterior, & medially; the other rotates and slides within mandibular fossa
TMJ Depression ROM
35-50mm
TMJ Elevation ROM
Teeth contact
TMJ Protrusion ROM
3-7mm
