THROWING PAINS.IS IT MECHANICAL? PHYSICAL? OR BOTH? Disclosure Nothing to Disclose at this time Jeffrey Lahti, PT/Partner Viverant Adam Barta Owner- Blizzard Baseball Academy July 7 th 2017 Objectives Complete history of injury Objective Evaluation of Throwing Athlete (Upper and lower extremity) Mechanical Analysis-initiating corrective techniques Putting the pieces together to restore the throwing efficiency History Pain (gradual or sudden) Any other areas of dysfunction (Lower extremity? Back?) Position(s) How many teams and games a week Growth Spurt? AllinaHealthSystem 1
Interesting Statistics 26% of youth players and 58% of high school pitchers in one study experience elbow pain 29% of 9- to 19-year-old boys experience shoulder pain (according to one study) and between 32% and 35% in two other studies 38% of high school pitchers experience shoulder pain. Athletes who pitch with a tired arm are 6 times more likely to suffer from elbow pain and 4 more times more likely to have shoulder pain than those who pitch when their arms aren't tired. Roughly half of youth pitchers reports elbow or shoulder pain at least once during the season. The risk of shoulder pain is 2 and a half times greater for pitchers who throw more than 75 pitches per game. The risk of elbow pain is 3 1/2 times greater for pitchers throwing more than 600 pitches per season Objective Evaluation Visual exam (Atrophy/asymmetry) ROM (Total Arc of motion)(gird) Strength (Scapular, RTC, Forearm) Flexibility (Arm, Chest, Hips, Ankle) Thoracic mobility Palpation (Bone/Tendons) Special tests Throwing Mechanics Mechanics Courtesy of New York Times (July 2, 2010) Arm Pain and Correlated Throwing Phase of Pathology 1) RTC Pain (Late Cocking/Acceleration/Deceleration) Phase) 2) Scapular Pain/Dysfunction (Deceleration) 3) Internal Impingement (Late Cocking) 4) GH Capsular Lesion (Late Cocking/Early Acceleration) 5) Osseous Lesions(more common in older throwers Late Cocking) 6) Biceps Tendon Lesions (Late Cocking/Early Acceleration) 7) Flexor Bundle/Pronator Strain (Deceleration) 8) UCL Pathology (Acceleration) AllinaHealthSystem 2

Separation momentum Disconnect with foot and arm(s) 4a - Foot strike and posture 4a - Hip position (belly button facing forward) 4b - Release / late launch 4b - Glove side AllinaHealthSystem 3
Disconnection What is it? When a body segment is acting independently from the trunk and spine Adds additional stress Limits energy production Difficulty with command and secondary pitches Key word: EFFICIENT 5 Key Pitching Pointers-- #1 #1 Elevated Distal Humerus 1) step behinds 2) connection balls Big 5-- #2 Big Five-- #3 #2 Forearm fly out #3 Inefficient back leg, hip, and glute 1) connection ball 1) double crow ups / jump backs AllinaHealthSystem 4
