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.
