What is RSI?

Repetitive Strain Injury (RSI) is pain or nerve problems in upper extremity (hands, arms, or

shoulders) can also include neck and back is a soft tissue disease (muscles and nerves)

Symptoms tightness, discomfort, stiffness,

burning in the hands, wrists, fingers, forearms, or elbow.

pain that wakes you up at night; tingling, coldness or numbnessin the hands,

and loss of strength and coordination in the hands

(CTS) is caused when median nerves thatcontrols the functioning of the hands andfingers become compressed inside a tunnelmade up of the wrist bones, or carpals.

Reasons for CTS injury

Long hours in the keyboard, especially those thattype more than four hours

Lack of circulation in the muscles that preventsnutrients and oxygen to reach the tissues

Inadequate rest and breaks

Poor posture including the sitting, placement ofhands on the keyboard and proper height of thekeyboard

Poor diet (lack of vitamins)

EYE STRAINS

Eye strain is the single largest complaint of

computer users causing soreness,

irritation, blurred vision, redness and

dryness of the eyes.


22/34

Reasons for this injury

Bad monitor resolution, flickering, or glare at the

monitor

Poor lighting conditions in the computer room

distance between eye and screen readability of

the screen

Electromagnetic radiation emitted by the CRT(UVA)

Staring at anything for a long period of time.


23/34

Symptoms of Eye Strains

Impaired vision, double vision and blurred vision

Difficulty in looking at one point for a period of time

Itchy dry eyes and discomfort while looking at theVDT

Headaches

Eye fatigue that can have seriousimpact later in life


24/34

Eye Strain Treatment

Use your knowledge ofErgonomics

Take breaks when you feel strained

Use your laptop when possible because the monitoremits less radiation

Use a monitor that holds a steady image withoutflickering.

Use the zooming function to improve readability

The screen should be kept 18-30 inches from ones eyesor about an arms length.

Discomgoogolation

It is defined asfeeling of distress or anxiety when unable to gainimmediate information access.

Derived from discombobulate which means illusion andGoogle

The internet users suffer from distress or anxiety when unableto get connected to the Internet.

They felt frustrated and

confused whilst unable to get

online. Some had higher stress levels.


28/34

Use internet only when necessary.

Try to have account on only one of the socialnetworking sites.

Indulge in other hobbies.

Take care of time while chatting.

If still suffered by online mania ,

consult psychologist.

There is even an anti-facebookblog called sickfacebook.com to

discuss issues.

STRESS & DEPRESSION Computer operators experience more stress than

any other occupational group the National

Institute of Occupational Safety and Health has

studied.


30/34

Other Computer Related

Health Hazards Back problems (pain) caused from the efforts of the muscle

to hold your posture for long periods of time

Skin rashes that are caused from the static fields in front ofthe screen causing ions and pollutants in the air to becomepositively charged and attach themselves to your negativelycharged skin (especially in low humidity)

Abnormal reproductive outcomes due to electromagneticradiation's affects on biological functions and biochemicalprocesses inside our cells

Cancer and leukemia (?)

Skin aging (?)


31/34

ERGONOMICS Derived from the Greek words ergon(work) andnomos(natural laws). Combined, it means THE LAWSOF WORK.

Study of designing and positioning workenvironment and computer equipment in a healthymanner

Designs of slope of the keyboard, keyboard height

(elbow height), computer tables, display screens.
