From another thread - "In my interpretation of the Ellenbecker video the issue involves putting the ball of the humerus and attached tissue (suprispinatus tendon, bursa sack?...) in a more confined space under the acromion and then doing the very violent and perhaps sometimes wobbly internal shoulder rotation as shown in this serve video. https://vimeo.com/27528701 The space under the acromion is more confined if the upper arm is high. Acromion illustrations https://www.google.com/search?q=acro...w=1312&bih=703 " Good luck. |

From another thread -
"Best to view the Ellenbecker video as I could misinterpret. At minute 8 he describes the shoulder orientation to minimize the risk of impingement. http://www.tennisresources.com/index...idid=3712&rv=1 Think of the line between the two shoulders and the line of the upper arm. If those lines fell in a straight line, the angle is 180°, and the shoulder internally rotates (upper arm axial rotation) well and impingement risk is low. As the upper arm rises relative to the shoulders the risk increases. I have read that 170° is still OK. Let's say that it is higher than recommended, at 150° for example - then there is more risk of impingement. You can also visualize the angle by extending the shoulder-shoulder line and considering the complementary angle. Then for example, 0° is upper arm straight out, 10° is the upper arm up slightly and still OK, 30° is the upper arm up and at increased risk of impingement. I see many players serving well beyond the 10°. The shoulder orientation requires lateral trunk flexion which may stress the back for some people." |

I checked out the video what year was it made? Was that dude just a USPTA pro talking about shoulder pt? Nothing new in the video that I did not already know from being a CSCS for the past 23 years. Bottom line is any overhead sport is bad for your cuff. If u are like me and have a type 3 u will get impingement sooner.
First the tendon rubs on the bone the bone protects itself by making a bone spur which cuts the tendon over time. My doc even created more more and even cut off 1cm of my collarbone. Both spurs regrown over a 12 years and so I got both shoulders scoped after having the open style surgery first. I opted for the open style first since the retear rate was lower compared to scope jobs at the time 1996 and 1999. I got scoped in 2010 and 2012. Looking back my Doc said they could grow back over time but I had no problems until one day it just pooped and made another hole in the tendon. I could have gotten an mri every year on each shoulder but that would have costed me 800.00 out of pocket every year. Plus staying still in a tube for 30 mins for each one is not fun rather get another surgery haha!! Funny thing I only serve slice and flat no kickers. I think the kick serve and american twist is far worse than slice or flat. What I learned is always wear your shoulder pads even in light practice. Also don't play clay court tennis which is good for your knees bad for your cuff. Hitting 5-6 balls chest height on hard court is way better than 8-12 balls shoulder or above your shoulder height on clay. Knee sugery was about 10 years ahead of shoulder surgery last time I checked.

I don't know when the video was made. He published a paper in 1998 on the subject but I could not locate it.
As long as you understand the shoulder-shoulder to upper arm alignment as you start back to serving that was the main point. Last edited by Chas Tennis : 01-02-2013 at 12:27 PM. |

Nah, Iam not buying into that. Even if I had perfect biomechanics and perfect muscle balance I would have still have a tear in my cuff. First impact then overuse and a type 3 ac joint caused my problems. Man was build to climb to to throw overhand.
