Science of designing workplaces, equipment and tasks within the capabilities of the human body and mind.
Ergo = work/effort Nomos = natural law/surroundings

The goals of ergonomics are to optimise:
human well-being overall system performance.

What does it all mean? 1. Human
• emotional and physical well-being • poor working habits
2. Machine • appropriate equipment • maintenance and safety of equipment
3. Environment • physical e.g. workstation design, temperature, lighting and noise • emotional e.g. relationships and support systems amongst colleagues

Repetitive Strain Injuries
Repetitive movements Sustained postures Poor postural habits Fatigue Decreased level of
fitness

Ideal Computer Station Design • Adjustable tilted screen. • Screen and work surface free of
glare and reflection. • Good lighting (avoid a glare or
reflection on the screen). • Adjustable chair with casters and
suitable armrests. • Space under the desk clear for
legs. • Keyboard and mouse in close
proximity.

Correct Sitting Posture Sit far back into the chair so that back
is well supported. Head in a balanced position (avoid
poking head forwards). Top of screen at eye level. Shoulders relaxed and upper arms
vertical. Forearms and wrists horizontal and
supported. Knees bent to +/- 90 degrees. Hips positioned slightly higher than
knees. Feet flat on the floor (foot rest for
shorter people).

Common Workstation Faults
Armrests are not suitable for the desk
![Page 12: National Secretaries and Personal Assistants’ Symposium 26 ... Talbot.pdf · National Secretaries and Personal Assistants’ Symposium . ... and mind. Ergo = work/effort Nomos =](https://reader034.fdocuments.us/reader034/viewer/2022042104/5e8255f17179e651f32975c7/html5/thumbnails/12.jpg)

Stressors
A significant life change or event can be a stressor. Either a major positive or negative event can be
stressful. Stressors may precipitate, exacerbate or perpetuate
neck and back pain.
![Page 17: National Secretaries and Personal Assistants’ Symposium 26 ... Talbot.pdf · National Secretaries and Personal Assistants’ Symposium . ... and mind. Ergo = work/effort Nomos =](https://reader034.fdocuments.us/reader034/viewer/2022042104/5e8255f17179e651f32975c7/html5/thumbnails/17.jpg)
The Mind-Body Connection
Brain has developed over millions of years. Most primitive part of the brain is the brainstem. Limbic system was the first true emotional component
of the brain to develop. Cortex allows for thought, reflection and analysis to
take place. Cortex facilitated the development of emotional
“fine-tuning “.
![Page 18: National Secretaries and Personal Assistants’ Symposium 26 ... Talbot.pdf · National Secretaries and Personal Assistants’ Symposium . ... and mind. Ergo = work/effort Nomos =](https://reader034.fdocuments.us/reader034/viewer/2022042104/5e8255f17179e651f32975c7/html5/thumbnails/18.jpg)
The Stress Response Signals are transmitted via the nervous system from the
brain to the body. Sympathetic nervous system is activated by the limbic
system. Hormones such as adrenalin, nor-adrenalin, cortisol and
prolactin are released. The body goes into “red alert” i.e. the “fight or flight
response”. Parasympathetic nervous system is activated when the
threat has passed. The body goes into “green alert” i.e. the “rest and digest
response”.

Symptoms of Stress Physical Emotional and Behavioural
Loss of appetite Constipation or diarrhoea Tiredness Insomnia Poor concentration and memory Skin rashes Colds and flu Reduced sex drive Chest pain
Irritability Irrationality Anxiety Emotionally variable Negativity Feeling of doom Intolerance to noise Over eating

Chronic Stress
Chronic stress is a common problem of modern living. Sympathetic nervous system remains constantly
aroused. Immunity system is suppressed. Internal organs are prone to disease. Recurrent musculoskeletal symptoms.
