Alternative keyboards and mouse(s) are designed to change the user’s posture. Though alternative peripherals have demonstrated a more neutral posture, to date, available research does not provide conclusive evidence that they reduce the risk of discomfort or injury. Subsequently, there is little information to assist people interested in purchasing alternative keyboards.

With this in consideration, here is some alternate input device advice:

• Assess how the equipment will fit with the workstation. Some alternative keyboards are extra wide, long, or high and may not fit on standard keyboard trays.

• Evaluate the peripherals which will affect the performance of the user. Review purchase options. If at all possible, test the product over a short time to determine a better alternative.

• Consider the sales and service issues. Understand warranty terms and how the peripheral will be maintained or repaired.

• Training. Like with any other piece of equipment, the employee should be trained on the appropriate use of the product.

• Grace period. When trying a new keyboard or mouse, allow at least a two week time frame to learn and evaluate the new set up.

• Follow-up. Users should be aware of any discomfort they experience while using a new keyboard. Because of different movements or increased use of certain fingers, alternative keyboards may cause new problems. Use should not be continued, however, if the new peripheral causes pain or discomfort.
