One drawback of manual printing is that using a squeegee is a repetitive task. With what is known today about carpal tunnel syndrome with regard to repetitive tasks, we highly recommends the use of wrist supports. Wrist supports (when worn properly) help protect against carpal tunnel syndrome without affecting the range of motion that is used when pulling a squeegee. Wrist supports should be worn on both wrists. They are inexpensive to purchase and are well worth the money. They are available from HarborFreight.com.
