My Personal Workstation My workstation includes two desks, two chairs, two computers with a mouse and keyboard, one phone, and two printers.

Potential Problems In My Workspace Keyboard & Mouse- I use both input devices for extended periods of time. Neither has a wrist rest, which helps keep my palms from resting on the edge of the desk and my wrists out of the flexion position.

Neither has a wrist rest, which helps keep my palms from resting on the edge of the desk and my wrists out of the flexion position.

Potential Problems Desk-The desk is about 3 feet tall with a wood laminate top with slightly rounded edges. Because the edges are still relatively sharp, leaning against them could pinch a nerve or restrict blood flow through the tissues Desk-The desk is about 3 feet tall with a wood laminate top with slightly rounded edges.

Potential Problems Chairs-The chairs have wheels, are slightly cushioned, and are not adjustable in any way. The chair is also about one foot shorter than the desk. The chair does not support the back, forces the arms, wrists and shoulders into tense and awkward positions. Chairs-The chairs have wheels, are slightly cushioned, and are not adjustable in any way.

Environment Adjustment Replace Existing Equipment-The desks should have rounded edges to reduce possible pressure points. The chairs need the arm height and chair height to be adjustable, and give back support by having a tilt adjustment.

Environment Adjustment Add Accessories to Existing Equipment- Wrist rests can be added to the keyboards and mouse to help promote a neutral wrist position. An adjustable document holder can be attached to the monitor to promote the proper head angle. A seat cushion can be added to the chair to help support the back. A footrest can be used to help keep thighs parallel to the ground and promote good posture to help prevent back, neck and shoulder pain.
