What causes RSI?
RSI is caused by making the same movement over and over again. For computer users RSI can result from poorly designed workstations with keyboards too high, ill-fitting chairs, stressful conditions, extended hours of typing, and using a mouse. Some of the most serious injuries that Dr. Emil Pascarelli (a specialist in RSI treatment) has seen have come from mouse use.

According to Dr. Pascarelli, ergonomic computer-related accessories are very hard to find. “We couldn’t find a single mouse or trackball we felt was safe to use for extended periods of time.” The computer keyboard is an ergonomic nightmare. It tends to force you into an unnatural palms-down (pronated) wrist-cocked position. This strains the delicate muscles and tendons of the fingers and wrists, reducing circulation. Arthritis and poor posture can also be contributing
