Chapter 13 Key Terms: Biomechanics and Ergonomics Flashcards
Base of Support
Foundation on which a body rests or stands, when people stand, their feet and the space between the feet define the base of support.
Biomechanics
A component of physics, the laws of Newtonian mechanics, applied to living bodies at rest and in motion.
Center of Gravity
Hypothetical point around which all mass appears to be concentrated.
Commonly attached medical equipment
Items clipped, fastened, or affixed to patient’s bodies to deliver substances, such as oxygen, medication’s, hydration, or nutrition, or drain away substances such as post surgical fluids or urine. Care must be taken when moving or positioning patients with these attachments, neither the patient nor the clinician should get injured during this activity. The equipment should also survive intact without damage or functional impairment.
Ergonomics
The study of a persons efficiency in the working environment.
Mobility muscles
Muscles that are found in the four extremities and design for movement, examples include the biceps femoris, biceps brachii, and gastrocnemius. These muscles have long white tendons and are also called white muscles.
Orthostatic hypotension
A sudden drop in blood pressure in the brain when a person stands up quickly from a sitting or supine position, causing the oxygen in the brain to drop and the person to become dizzy and prone to falling.
Stability muscles
Muscles that supports the torso and are designed to provide postural stability, examples include the latissimus dorsi, abdominal group, and erector spinae. These muscles tend to have thick red muscle bellies and are also called red muscles.
Work-Related Musculoskeletal Disorder (WRMSD)
Injury or disorder of the muscles, verves, tendons, joints, Cartilage, and spinal discs, in which work environment and performance contribute significantly and/or the condition is made worse or persists longer due to work conditions.
