Welcome to the Future of Shoulder Health

The SHARQ Shoulder and Rotator Cuff Stretching and CPM  Machine

Is a device designed for stretching the shoulder into external and internal rotation.

Research and use with our customers has shown that used properly it will

                       1) Speed rehabilitation of shoulder injuries

                       2) Prevent shoulder injury and relieve chronic shoulder pain

                       3) Enhance athletic performance 


 Comfortable Tension Stretching (CTS)

Is an innovative technique of stretching for the treatment, prevention and rehabilitation of musculo-

skeletal injuries.  This extremely effective methodology was developed by John J. Quintinskie Jr.,

Ph.D. over the last 20 years.  It was inspired by research done in the 1970's and 80's that showed

that low load-prolonged stretch is a very powerful inducer of skeletal muscle growth(1,2,3,4,5).
