FYI: I have published a book titled: "Shoulder Pain? The Solution and Prevention"
This book is based on 25 yrs clinical research on healing and preventing the subacromial impingement syndrome and adhesive capsulitis (frozen shoulder) as well as decreasing the importance of small rotator cuff tears. The hanging exercise is especially effective in relieving shoulder pain for the overhead athlete such as throwing sports, lap swimming, etc.
Included in the book are a variety of patients and their testimonials, Volume CT scans performed on subjects in the simulated hanging position (using traction weights to reproduce the hanging force in the horizontal position) to disclose the anatomy in this position and other types of arm elevation, and instructions for the hanging and accompanying weight lifting exercises.
The book is being marketed by The Kirsch Institute for Shoulder Research LLC.
It is written for the common person, the difficult terminology of medicine simplified. It is available at Amazon.com, Barnes and Noble or the Kirsch Institute @ www.kirschshoulder.com -Strider
