Pre-Season Screening for GIRD February 8, 2016 Brian L. Siddall, M.A., A.T., ATC Supervisor of A.T. Services
TOTAL MOTION CONCEPT • Anatomy of shoulder allows for maximum mobility – but less stability • Role of RC Muscles is to spin the ‘Ball” in the socket – keeping it centered • Demo: E.R. Vs I.R. • ISSUE: I.R. – where deficits occur w/ O.H.T.
MEASURING TOTAL MOTION • Before measure – observe cross-over / back scratch AROM • Determine summation of shoulder AROM – ND vs. DS (Looking for deficits in I.R.) • Find in ND: ↓ ER ↑ IR Find in DS: ↑ ER ↓ IR
EXAMPLE - Pre Season Screen • N.D. D.S. • ER 90°100° • IR 80°40 ° • ------------ -------------- • 170 ° 140 ° If more than 15 degrees – potential for problems GIRD
GIRD • Humeral head gets forced ‘forward” in socket and results in impingement of rotary cuff tendon between the bones. (Small tunnel for rc tendon to go thru) • Also, shortened post-scapular muscles keep humeral head moving forward – ‘Off Center”
HOW TO CORRECT • Sleeper Stretch Lengthens scapular muscles Will re-center humeral head Hold 30 sec. – 5x • Cross-Over Stretch Biceps to Chin Hold 20 sec. – 5x Don’t twist torso
Rotator Cuff Exercise: • Endurance Vs. Power • Minimal weight • Higher Repetitions • Burn Factor • 1-3 sets, 25-30 reps
RC Exercise • Internal Rotation - Neutral / 90/90 • Elbow maintained 90 degrees • Errors: elbow off side, rotating at spine
RC Exercise • External Rotation - Neutral / 90/90 • Elbow maintained 90 degrees • Errors: elbow off side, rotating at spine
RC Exercise • Prone Horizontal Abduction • Raise the arm with the thumb pointed up • Slightly above shoulder height
RC Exercise • Scaption • Arms at side: • 35-45 degrees from center of body • Shoulder height
Essential Principles & Strategies • Strength and endurance of scapular and rotator cuff musculature • Encourage good posture • Maintain adequate flexibility of muscles and capsular tissues • Reinforce proper execution of all exercises
