Rotator cuff syndrome is one of the most common orthopedic injuries of the upper extremities, affecting especially athletes and the elderly. One cadaveric study found that 51% of random subjects had at least one rotator cuff tear.
The rotator cuff supplements the small shoulder joint to keep the bones functioning properly. It is composed of four muscles: the supraspinatus, the infraspinatus, the teres minor and the subscapularis. Any one of these muscles can tear, but 90% of rotator cuff syndromes involve the supraspinatus.
We have developed and validated a two-step method that teaches people to substitute the subscapularis for the supraspinatus, enabling them to raise their arms completely and painlessly. We have tested it on over 1200 people with MRI-documented rotator cuff tears, and followed 50 patients for 2.5 years, some for as long as 15 years, confirming that the method continues to be effective over that time period. The two-step technique often takes less than 5 minutes to complete, and appears to last a lifetime. It involves no drugs or injections, and is strikingly simple for most people.
