Understanding Ergonomics and MSDs

Carpal Tunnel Syndrome

• Pain, numbness, and tingling in the hand and arm.
• Associated with repetitive flexion and extension of the wrist.

Cumulative Trauma Disorders (CTDs)

• Painful conditions resulting from ongoing stresses.
• Affect muscles, tendons, nerves, and joints.

Ergonomics

• The study of people in their work environment.
• Focuses on preventing injuries.

Maximum Horizontal Reach

• Achieved when the upper arm is fully extended.

Maximum Vertical Reach

• Achieved by a vertical sweep of the forearm.
• Elbow kept at midtorso level.

Musculoskeletal Disorders (MSDs)

• Painful conditions affecting both muscles and bones.
• Examples include neck or back pain and carpal tunnel syndrome.

Neutral Position

• Body position maintained for prolonged periods.
• Involves a natural curvature of the spine.

Normal Horizontal Reach

• Achieved by a sweep of the forearm with the upper arm held at the side.

Sprains

• Injuries caused by sudden twisting or wrenching of a joint.
• Involve stretching or tearing of ligaments.

Strains

• Injuries caused by extreme stretching of muscles or ligaments.

Thenar Eminence

• Refers to the fleshy mound on the palm at the base of the thumb.

Carpal Tunnel Syndrome (CTS)

• A condition that causes pain, numbness, and tingling in the hand and arm.
• Often associated with continued flexion and extension of the wrist.

Cumulative Trauma Disorders (CTDs)

• Painful conditions that result from ongoing stresses to muscles, tendons, nerves, and joints.

Ergonomics

• The study of people in their work environment and how to prevent injuries.

Maximum Horizontal Reach

• The reach created when the upper arm is fully extended.

Maximum Vertical Reach

• The reach created by a vertical sweep of the forearm while the elbow is kept at midtorso level.

Musculoskeletal Disorders (MSDs)

• Painful conditions that affect both muscles and bones.
• Examples include neck or back pain and carpal tunnel syndrome.

Neutral Position

• The position of the body to maintain for a prolonged period, with a natural curvature of the spine.

Normal Horizontal Reach

• The reach created by a sweep of the forearm with the upper arm held at the side.

Sprains

• Injuries caused by sudden twisting or wrenching of a joint.
• Involve stretching or tearing of ligaments.

Strains

• Injuries caused by extreme stretching of muscles or ligaments.

Thenar Eminence

• The fleshy mound at the base of the thumb.

This quiz covers key concepts related to ergonomics, cumulative trauma disorders, and musculoskeletal disorders. Participants will learn about the effects of repetitive motion and how to maintain neutral positions to prevent injuries. Gain insights into the definitions and characteristics of various conditions affecting the musculoskeletal system.
