Anthropometry - Science that deals with the size, mass,
and shape of the human body and its components.
Biomechanics - Science that uses engineering concepts to describe
motions of the body.
CTD (Cumulative Trauma Disorder) - Premature wear and tear damage
to specific body structures.
Carpal Tunnel - Tunnel formed by the carpal ligament and the
bones of the wrist.
Carpal Tunnel Syndrome - Disorder associated with impingement
to the median nerve as it travels through the wrist.
De Quervain's Disease - A common type of stenosing tenosynovitis
(combination of tenosynovitis and tendinitis).
Epicondylitis - Technical term for "tennis elbow".
Ergonomics - An applied science that seeks to design work requirements
to within human capabilities.
Ergonomic Risk Factors - Conditions of a job, process, or operation
that contribute to the risk of developing Cumulative Trauma Disorders.
Fatigue - A reduction in the ability to exert force in response
to voluntary effort.
Force - An action that changes the state of rest or motion of
a body to which it is applied.
Kinesiology - The study of human movements as a function of
the construction of the musculoskeletal system.
Lifting Index - Ratio between load being handled and the recommended
weight limit.
Ligament - Connective tissue attaching bone to bone.
Mechanical Stress - Pressure to the skin and soft tissues from
direct contact with parts, tools, fixtures, etc.
Median Nerve - Nerve feeding the thumb and first two fingers
of the hand.
Muscloskeletal Disorders - Disorders and diseases of the muscles,
connective tissues, and surrounding neural tissues.
Optimal Work Area - Area in front of the body defined by the
keeping the back straight, the shoulders neutral, and the hands
between hand rest and elbow height.
Personal Risk Factor - Personal characteristics that increase
the likelihood that an individual will develop a work-related musculoskeletal
disorder.
Physiology - Science that measures people's capacity to do work
and their body's reaction t o doing work.
Radial Deviation - Any noticeable deviation of the wrists toward
the thumb.
Reaction Torque - Force created when a threaded fastener forms
a solid joint during the run-down phase.
Risk Factors - Conditions that increase the likelihood of a
certain outcome. WMSD risk factors are conditions that increase
the likelihood of developing a work-related musculoskeletal disorder.
Sprain - Injury to ligaments around a joint.
Strain - Injury to muscle or tendon.
Synovia - Membranes lining the inside of joint capsules and
moving surfaces of joints. They secrete the synovial fluid, which
lubricates joints.
Tendinitis - Swelling in the tendons, resulting in pain.
Tendon - Connective tissue that transmits the force from muscles
to the bone.
Tenosynovitis - Swelling in the tendon and tendon sheath, resulting
in pain.
Ulnar Deviation - Any noticeable deviation of the wrist opposite
the thumb.
Upper Extremities - The arms and hands and associated joints
Whole Body Fatigue - An overall reduction in the ability to
exert force in response to voluntary effort.
WMSD (Work-Related Musculoskeletal Disorder) - Disorders and
diseases of the muscles, connective tissues, and surrounding neural
tissues that are caused or aggravated by work causal factors.
