Key long cervical restrictors that sideband and rotate to opposite sides
Key long cervical restrictors that sideband and rotate to the same side
Levator scapula: due to TWIST in it from rotation during development. ASSOCIATED WITH C2 dysfunction.
If you have a thoracic dysfunction at T4 ERS L, T5 ERS R, and T6 ERS L, what muscles are inhibited?
What are the key hypertonic shoulder muscles?
Levator Scapula (C2)
Latissimus dorsi (C4-C5)
What are the key inhibited shoulder muscles?
Middle and lower trapezius (lower T spine)
Serratus anterior (mid T spine)
Postural muscles of the upper quarter
Flexors of the upper extremity
Dynamic muscles of the upper quarter
Middle and lower trapezius
Extensors of the uppers extremity
Bilateral Shoulder Abduction Maneuver is a screening test used to assess for what?
1) Asymmetry of gliding motion of scapula on trunk
2) Winging of scapula
Bilateral Shoulder Abduction Maneuver: Inhibited muscles
Lower and Middle Trapezius
Unilateral Shoulder Abduction Maneuver: Muscle Firing Sequence
Normal: Contralateral Quadratus lumborum should fire
Abnormal: ipsilateral Quadratus lumborum fires.
Ideal Sequence: 1st->Supraspinatus, deltoid, infraspinatus, middle and lower trapezius, contralateral quadratus lumborum
Dysfunctional sequence: Tight levator scapula fires and inhibits ideal firing pattern, late firing of middle and lower trapezius, ipsilateral QL fire (instead of contralateral)
Anterior Shoulder Postion Test: Hypertonic muscles
POSTERIOR SHOULDER CAPSULE
Anterior Shoulder Position Test: Inhibited muscles
