3. “HYPER-ANGULATION”
1. Anterior instability
Excessive humeral head
translations
2. Posterior shoulder stiffness
Alterations of glenohumeral
kinematics
3. Scapular dyskinesis:
Insufficient scapular retraction
during cocking

Chronic shoulder pain (6 months)
During serve and smash, pain at
the back of the shoulder
G.I.R.D.
Pain in ABER – positive Relocation

5. Patient presentation
Anterior tilt scapula during rest
and arm movements
Positive tests scapular

7. Stretching posterior
shoulder: clinical experience
Ann Cools Wrightington nov 2012

8. POSTERIOR SHOULDER
STRETCHING
Sleeper’s stretch & cross body
stretch improve ROM (Mc Clure
2005)
Additional manual mobilisations
improve ROM (Manske 2010,
Cools 2011)
Improvement ROM is related to
reduction of symptoms (Tyler
2010)

9. STRETCHING G.I.R.D.:
influence on the subacromial space?
Measurements:
- Acromiohumeral distance (Echoblaster 128; Telemed, Vilnius,
Lithuania)
- Glehonumeral ROM (Acumar inclinometer)
Quantifying acromiohumeral distance in overhead athletes with glenohumeral
internal rotation loss and the Ann Cools Wrightington nov 2012
influence of a stretching program. Maenhout A,
Van Eessel V, Vanraes A, Van Dyck L, Cools A. (AJSM May 2012)

10. STRETCHING G.I.R.D.:
influence on the subacromial space?
Intervention:
- 6 weeks stretching
- Sleeper’s stretch

15. Stretching pectoralis minor: literature
Borstad et al. JOSPT 2005: short PM
influences scapular kinematics and induces
changes similar to impingement related
dyskinesis
Cools & Johansson BJSM 2010: significant
decrease PM length in elite junior (11-17yr)
tennis players
Reeser PM&R 2010: tight PM is associated
with history of shoulder pain in volleyball
players
Borstad et al. JSES 2006: unilateral self
stretch (in 90° ABER) best results,

19. Scapular muscle balance during RC
exercises - progression

20. Scapular muscle control during basic daily
activities: external rotation component!

(Kibler 1998, Vanderhoeven 2006, Kibler 2006, Cools & Walravens 2005, Cools 2008)

21. Results 5 weeks
treatment
Basic clinical exam is (-)
Scapular control increased, however not
sufficient
No pain during (beach) volleyball, however
no full return to sport (season)
Working on other links of the kinetic chain
(very poor pelvic stability, contol during
squat...)
Continue self-stretching
