Mike Roberts and the good folks at Central Mass Physical Therapy did an excellent job hosting Impingement and Instability this past weekend in beautiful Worchester, MA. I was able to spend some time visiting family and friends and I took the opportunity to visit Minuteman National Park in Concord MA. Here the British Red Coats faced down the early colonists across the Old North Bridge prior to the firing of "The shot heard round the world". I went to the nearby Acton Memorial Library and saw the actual sword, a blood stained hat band and a lock of hair from 3 of the colonists that died on that day. Cool stuff. I'm a history buff and I had an awesome time taking in some of the great American history that region has to offer. Anyhow, as far as the course was concerned, we had a great experience exploring secondary level PRI integration with a fantastic group of people. We had a fun combination of rehab, strength, performance and training professionals in attendance who were willing to do their part to make it a great learning experience for the group. They came together to take a more advanced look at the science of PRI, after having done some of the due diligence required with our primary course material. Its always great to take things to the next level in a secondary course like this, especially with an interactive group who came prepared with so many great questions. We talked about the human sense organs and how all things come together to help us sense the space around us and the ground beneath us. The concept of reference centers was well received and it seemed to help all in attendance become better at what they already knew about PRI movement science. The questions were awesome and it was fun to demonstrate so many of the principles taught on course attendees with specific instabilities or a lack of perception and awareness across specific reference centers. Nothing teaches a confusing principle better than seeing it demonstrated on a person with a similar deficit or problem to someone you have seen yourself and didn't know what to do with. We talked about he many ways and reasons the human system becomes lateralized to the right and how the neurology of perceiving space, both the space around us and the space within us, helps us negotiate these lateral tendencies. There were a lot of "ah ha" moments as the class considered the affect of asymmetrical hyperinflation, overactive unilateral muscle chains and asymmetrical ways of stabilizing our body when we stop to rest or attempt to move. These principles were put into play to decrease the negative effects of calcaneal instability, patella femoral instability, ilium instability and scapular instability. The thoughtful questions from the group and their requests to see techniques demonstrated throughout the course added to our overall learning experience. So, thanks again for all the great contributions everyone and for making our time together so practical and fun.
