Can Chronic Neck Pain Be Eliminated or Healed?
Selected Testimonials and Ergonomic Courses
B.J. Chang PhD and Karl M. Schwartz MBA

Ergonomic postures are not a natural posture such as a tennis stroke, baseball swing or golf swing. Our natural instinct is to tilt our heads and twist our bodies to get a closer view of our work. Using loupes effectively and ergonomically, by sitting upright and rotating our eyes down through a strong declination angle, takes practice.
