The KOR – a Leader in Softball Physical Therapy

Saving the Softball Athlete  

Our softball physical therapy team consists of Donn Dimond, PT, OCS and Kent Morimatsu, DPT.  

Examination and Assessment

The key to proper rehabilitation for the softball player is a thorough examination and assessment.

* Using very specific and  objective equipment we are able  to closely measure the   player’s strength and mobility of  her shoulder, hips, and trunk.


  •  Using machine-vision high speed cameras linked to JC  Video software, crystal clear frame-by-frame and slow motion playback, we are able  to clarify possible mechanical  red flags.  


  • Our goal is to be the detective for the player and address the true cause of their pain and decreased ability to throw.


  • Based on the deficits noted during the examination, we strengthen the specific muscles that are found to be weak or not within the proper strength ratios. 

  • Once the primary muscles are identified and worked on, will also work on the secondary muscles to ensure that the body is able to work together and reach its pain free potential.  


 Because of the nature of throwing, there is considerable stress placed on the arm. The stress placed through a softball pitcher's arm is equivalant to the stress placed on the arm with a baseball pitch.  

  •  This force, along with shoulder weakness, causes tightening of shoulder. This tightening can cause pain and dysfunction in the shoulder. 

  • This is why the majority of softball players with pain need aggressive mobilizations to break up the tissue to allow for proper pain free motion.  

  • Mobilizations paired with exercise have been shown to be more effective for shoulder pain than just exercise or mobilizations by themselves.  


 Using our machine-vision high speed cameras linked to the JC Video software, we are able to clarify possible mechanical red flags. 

  • Most common mechanical flags are the hips not opening up soon enough or trunk rotation happens too early in the pitching cycle. 

  • Based on current research it has been found that a pitcher with increased knee extension, quicker pelvis and hip rotation, and decreased elbow extension at ball release will minimize potential for injury. 

Injury Reduction Team Screenings

 Contact us if you would like to have one of our  softball experts screen your players for injury risk.  The optimal time frame to identify and treat those at risk of injury is 6-8 weeks prior to the start of the season.

Community Talks

Contact us if you would like to have one of our softball experts talk to your group about the common factors that lead to injuries in softball players and what you can do to minimize the risk.
