Study Notes
Ergonomics
Posture Assessment
- Definition: Evaluation of body positions to optimize comfort and reduce strain.
-
Key Elements:
- Static Posture: Long-term positions; monitor for muscle fatigue and discomfort.
- Dynamic Posture: Movement analysis; ensure smooth transitions and proper alignment.
-
Assessment Techniques:
- Visual inspections for alignment (head, shoulders, hips, knees, ankles).
- Use of digital tools (software/apps) for measuring angles and body angles.
- Self-assessments through questionnaires or checklists.
-
Ideal Posture Guidelines:
- Feet flat on the ground or supported.
- Back straight with lumbar support.
- Elbows at a 90-degree angle.
- Monitor at eye level to avoid neck strain.
Human Factors Engineering
- Definition: The study of how humans interact with systems and environments.
-
Objectives:
- Enhance user performance and safety.
- Minimize errors and discomfort in user interactions with tools and technology.
-
Key Principles:
- User-Centered Design: Involves users in the design process to meet their needs.
- Ergonomic Design: Focus on fit between user and equipment; considers physical and cognitive abilities.
-
Application Areas:
- Workplace design (furniture, tools).
- Software interfaces (usability, accessibility).
- Product design (easy to use, understand).
Repetitive Strain Injuries (RSI)
- Definition: Injuries caused by repetitive motion or sustained awkward positions.
-
Common Types:
- Tendonitis (inflammation of tendons).
- Carpal Tunnel Syndrome (compression of the median nerve).
- Bursitis (inflammation of bursae).
-
Symptoms:
- Pain, stiffness, or swelling in affected areas.
- Numbness or tingling sensations.
- Reduced range of motion.
-
Prevention Strategies:
- Ergonomic workstations (adjustable chairs, desks).
- Regular breaks and stretching exercises.
- Proper tool usage (ergonomic handles, lightweight materials).
-
Treatment Options:
- Rest and ice application.
- Physical therapy.
- In severe cases, medical intervention (surgery).
Posture Assessment
- Evaluation of body positions aims to enhance comfort and minimize physical strain.
- Static Posture: Focus on long-term body positions; important to monitor for signs of muscle fatigue and discomfort.
- Dynamic Posture: Involves analyzing body movements; ensures proper alignment and smooth transitions during activity.
-
Assessment Techniques:
- Visual inspections are essential for checking alignment of key body parts (head, shoulders, hips, knees, ankles).
- Digital tools, such as software and apps, measure angles and overall body posture.
- Self-assessments can be conducted using questionnaires and checklists to identify issues.
-
Ideal Posture Guidelines:
- Feet should be flat on the ground or supported for stability.
- A straight back with lumbar support promotes comfort.
- Elbows should be kept at a 90-degree angle to reduce strain.
- Monitors should be positioned at eye level to minimize neck strain.
Human Factors Engineering
- Study of the interaction between humans and various systems or environments.
- Objectives include enhancing user performance and safety while reducing errors and discomfort.
-
Key Principles:
- User-Centered Design: Engages users in the design process to ensure their needs are addressed.
- Ergonomic Design: Ensures compatibility between the user and equipment, considering both physical and cognitive capacities.
-
Application Areas:
- Workplace design must focus on ergonomic furniture and tools.
- Software interfaces should prioritize usability and accessibility.
- Product design should emphasize ease of use and understanding.
Repetitive Strain Injuries (RSI)
-
Injuries are triggered by repetitive motions or sustaining awkward positions over time.
-
Common Types:
- Tendonitis involves tendon inflammation.
- Carpal Tunnel Syndrome results from median nerve compression.
- Bursitis is characterized by inflammation of the bursae.
-
Symptoms:
- Commonly manifests as pain, stiffness, or swelling in the affected regions.
- May cause numbness or tingling sensations as well as reduced range of motion.
-
Prevention Strategies:
- Workstations should be ergonomic, featuring adjustable chairs and desks.
- Incorporating regular breaks and stretching exercises is crucial to prevent strain.
- Correct tool usage, such as ergonomic handles and lightweight materials, can significantly reduce injury risk.
-
Treatment Options:
- Rest and application of ice are primary initial treatments.
- Physical therapy can assist with recovery.
- In severe cases, surgical intervention may be necessary.
