Tanner Thomas, PT,DPT Community Rehab Physical Therapy Baseball Players ◦ Position Players vs. Pitchers Softball Players ◦ Position Players vs. Pitchers Things to consider ◦ Pitching is a combination of ROM, balance and strength throughout several joints ◦ ROM/Strength imbalances will increase risk of injury ◦ Poor mechanics increase risk of injury General History Symptoms ◦ Onset of symptoms-trauma or repetitive ◦ Pain When and where???-shoulder,elbow What phase of throwing is painful Multiple joints ◦ How long w/ symptoms What position does player play? ◦ Position vs. Pitcher or both!! ◦ Intensity and Duration of throwing How many games per week?? How much throwing on the side? Shoulder/Scapular AROM/PROM ◦ Rotational mobility ER/IR at 90° abduction Norms: ER=137°± 15° IR=40°± 10° Total rotational motion: ER/IR=TRM 177°±16° Wilk et al.2008 Horizontal Adduction ◦ Is the scapula moving??? Elbow ROM Trunk ROM-Thoracic/Lumbar ◦ Rotational movement 45° bilaterally should be minimum ◦ Flexion/Extension Important for follow-through Hip ROM ◦ Rotational Mobility: IR= 30°± 5° ER=45°± 7° Strength ◦ Shoulder/Scapular Strength-All planes Pain or crepitation w/ resisted motion? Assessment at neutral and 90/90 position ER/IR! IR: 35-40% stronger than ER ◦ Elbow/Wrist strength ◦ Core strength/Stability VERY important in mechanics ◦ Hip/Knee Strength Base is EVERYTHING Rotational Hip Strength Special Tests ◦ Hawkins-Kennedy, O’Brien’s, Speed’s, etc. Treatment of impairments ◦ ROM and Strength deficits in the trunk, hip and shoulder/scapula Mechanics-Soon to come!! ◦ Minimizing the amount of mechanical changes in the patients throwing motion is a must ◦ “Tweeking” faulty mechanics to decrease overall risk of injury is acceptable Phase 1-Acute Phase ◦ Diminish pain and inflammation Modalities as appropriate-ice,ionto,etc. Modification of activities Limiting throwing and certain exercises Stretching exercises-limitation of IR GIRD-Glenohumeral Internal Rotation Deficit Due to posterior muscle tightness Diagnosed by more than 20-25° loss of IR when compared to other side Sleeper stretch w/ lock down of scapula Manual sleeper stretch Limitation in horizontal adduction Supine Horz. Add w/ IR and manual stabilization Phase 1 ◦ Sleeper stretch ◦ Horizontal Adduction Stretch Phase 1 cont. ◦ Posture Common in overhead athlete to demonstrate poor posture Tightness in pec minor is common as well as forward head ◦ Strength Deficits Restoring strength to ER’s and scapular stabilizers Core and LE strengthening and proprioception Phase 2-Intermediate Phase ◦ Continued Strengthening of ER’s and Scapular stabilizers Begin utilization of the “Thrower’s Ten” exercise program Full can vs. empty can for supraspinatus Scapular NMR control drills ◦ Maintain soft tissue flexibility ◦ Continuation of core and LE strengthening Participate in running program Phase 2 ◦ Working on protraction/retraction ◦ Elbow in pronation ◦ Sets of 10-15 as tolerated Phase 3: Advanced Strengthening Phase ◦ Continuation of Throwers Ten w/ manual end range resistance ◦ Dynamic Stabilization Drills 2 lb plyoball throws into trampoline from end range ER Scapular Horz. Abd. on a physioball Seated ER on physioball w/ single leg support Increased w/ rhythmic stabilization ◦ Shoulder endurance activities “Wall Dribbling w/ weighted ball UE biking Wall arm circles Phase 3-cont. ◦ Initiating “mirror” throwing Working on proper mechanics w/o the use of a ball Only started after pain free ROM and WFL strength ◦ Interval throwing Starting at 45ft, progressing to 60 ft Must be able to throw w/ no pain to 120 ft before beginning a off the mound program Phase 4-Return to Throwing Phase ◦ Continuation of strengthening/flexibility exercises for UE/LE and core ◦ Continuation of Phase 1 Interval Throwing Program ◦ Begin initiation of Phase 2 (Off the Mound) Careful monitoring of thrower’s mechanics and intensity 50% isn’t always 50%!!!! Phases of Throwing ◦ Sequence of body segment motions ◦ Not going to be “Picture Perfect” for every thrower! Wind Up ◦ Good balance over stance leg ◦ Ends w/ knee flexed to maximum height Early Cocking/Stride ◦ Begins w/ stride towards to the plate and arms breaking ◦ Supraspinatus, Infraspinatus, teres minor active to initiate ER ◦ Ends when front foot hits the ground Late Cocking ◦ Between foot contact and maximum ext. rotation ◦ Scap retracts, supraspinatus for GH compression ◦ Increased trunk rotation Acceleration ◦ Max ER til release of ball ◦ Max elbow extension velocity Deceleration ◦ Considered the most violent phase of pitching ◦ High eccentric biceps activity to slow elbow ◦ Eccentric loading of posterior cuff to resist distraction forces Follow Through ◦ Arm motion ends ◦ Pitcher is in proper fielding position Stance Phase of windup Solid Base w/ heels on mound Relaxed elbows and shoulders Feet shoulder width apart Small Step Back Minimal 4-6” step back Maintain weight on ball of foot Balance Position Controlled raising of the lift leg Need to control this position Should be able to hold this position as long as asked Power position Ball facing away from pitcher T-pattern Drive off of mound w/ back leg Throw to plate Stride foot toward plate Elbow equal to shoulder level Chest not too “open” Follow through Flexed knees Facing batter Squared Feet What’s to come?? ◦ Softball mechanics ◦ Performance drills
