Break ingrained patterns of movement, e.g., by incorporating tours of duty (if possible). It is also helpful to place work equipment such as telephone, printer, copier further away, so that their use already leads to a small break.
Introduce movement breaks as well as stretching exercises in the daily work routine to relax the affected muscles and joints. Suitable exercises are:
Shake out arms
Press hands against each other (wrists are bent), hold for a few seconds and release again
Clench fist and slowly open again, first with bent fingers and finally with stretched fingers
Head slowly tilt in different directions. This prevents tension in the head and neck area
Ergonomic workplace design:
Office chair should be height adjustable and swivel.
V-shaped curved keyboard, if necessary with hand rest in front of the keyboard.
Monitor should be adjustable in height and viewing angle.
Use ergonomically designed mouse.
Use mouse pad, this makes the mouse easier to move.
If necessary, test out keyboard with integrated scroll mouse.
Provide sufficient legroom under the desk.
If necessary, use alternative input methods such as voice software.
In between, execute short commands with the keyboard to interrupt the monotonous mouse movements.
