Treat your own rotator cuff? Who needs to worry about that? According to the medical research, a lot of people. The rotator cuff, a group of four, flat tendons that connect to the critical muscles that stabilize your shoulder, can cause a lot more problems than you might think. Consider a few of these statistics from the published literature: .It's simply just a matter of time until the majority of shoulders get a rotator cuff tear. According to Magnetic Resonance Imaging (MRI) scans, approximately 4% of people under forty years of age have a torn rotator cuff. After age sixty, however, 54% of people have one (Sher 1995). .Once the rotator cuff gets torn, it doesn't look good either. One study followed a group of patients with tears in their rotator cuffs and found that 80% of the them went on to either enlarge or turn into full thickness tears-in less than a two-year period (Yamanaka 1994). As you can tell, rotator cuff problems aren't just for elite athletes. Seriously consider investing just a few minutes a week doing the simple exercises in this book if you: .have been diagnosed with either a partial or full thickness rotator cuff tear (yes, many studies show that even full thickness tears can be helped with exercise ) .experience shoulder pain .do upper body weight lifting .have a job or play a sport where you do a lot of work with your arms above shoulder level .have been diagnosed with "impingement syndrome" .want a healthy and properly functioning rotator cuff So whether you already suffer from a rotator cuff problem, or simply want to prevent one, Treat Your Own Rotator Cuff will guide you step-by-step through an evidence-based program that can iron-plate your shoulders in justminutes a week.
