Definition of rehabilitation

Need for rehabilitation

1. Reduce disability and dependence
   Helps the person perform activities such as walking, bathing, dressing, eating, toileting, and communication.
2. Restore maximum functional capacity
   Improves movement, strength, balance, endurance, coordination, and self-care ability.
3. Prevent complications of immobility and disability
   Prevents contractures, pressure sores, muscle wasting, deformity, deep-vein thrombosis, chest complications, and loss of bone mass.
4. Promote psychological well-being
   Reduces fear, anxiety, depression, low self-esteem, and social isolation that can follow chronic illness or disability.
5. Facilitate social reintegration
   Enables participation in family activities, education, community life, and recreation.
6. Facilitate vocational independence
   Helps a person return to previous employment where possible, or acquire skills for suitable alternative work.
7. Improve quality of life
   Supports independent, meaningful, and dignified living despite residual impairment.
8. Reduce the burden on family and society
   By reducing long-term dependence, hospitalization, caregiving needs, and economic loss.
9. Provide appropriate aids and environmental modifications
   Includes prostheses, orthoses, wheelchairs, walking aids, communication aids, home modifications, and accessibility measures.

Types of rehabilitation

2. Individualized care
   The programme should be based on the patient's age, diagnosis, disability, occupation, home environment, motivation, and personal goals.
3. Goal-oriented approach
   Functional goals should be specific and realistic, such as independent transfer from bed to chair, walking 20 metres with a walker, or returning to work.
4. Multidisciplinary teamwork
   Rehabilitation requires cooperation among doctors, physiotherapists, occupational therapists, nurses, psychologists, speech therapists, social workers, vocational counsellors, the patient, and family.
5. Active patient participation
   The patient should participate actively in goal setting and treatment.
6. Family involvement
   Family members should be educated about care, positioning, exercises, prevention of complications, and emotional support.
7. Continuity of care
   Rehabilitation may continue from hospital to home, outpatient department, workplace, and community.
8. Community integration
   The programme should help the person function in their real environment, not only in the hospital.

• The centre of the screen should be slightly below eye level.
• The worker should not need to bend the neck forward or backward to view the screen.
• Tilt the screen slightly backward if needed to reduce glare.
• Use an adjustable monitor stand if the screen is too low or too high.
• If dual monitors are used equally, place both centrally in a slight V-shape.
• If one monitor is used more often, place that monitor directly in front.

Prevention of eye strain

• Adjust screen brightness and contrast comfortably.
• Increase font size instead of leaning forward.
• Avoid reflections from windows or overhead lights.
