Some types of low-impact forces include:
Dynamic force: A force that you exert through movement, such as pressing the
keys while typing or clicking the mouse buttons.
Static force: A force that you maintain for a period of time, such as holding your
mouse or cradling the phone.
Contact force: A force that occurs when you rest on an edge or hard surface,
such as resting your wrists on the edge of your desk.
To reduce the effects of low-impact forces on your body, try the
following:
● Type with a light touch, keeping your hands and fingers relaxed, because it
takes little effort to activate keyboard keys.
● Use a light touch when clicking a mouse button or when using a joystick or
other gaming controller.
● Hold the mouse with a relaxed hand
and do not grip the mouse tightly.
● Avoid resting your palms or wrists on
any type of surface while typing (see
detail
7
). The palm rest, if provided,
should only be used during breaks from
typing.
● Relax your arms and hands when you
are not typing or using your mouse. Do
not rest your arms and hands on edges,
such as the edge of your desk.
● Adjust your chair so the seat does not
press into the back of your knees (see
detail

).
