Notes on Section Two: The Problem With Sitting (For consultants)

This section differentiates the different kinds of sitting needed in the office, and clarifies the very different health risks between work and leisure.

Research studies show that the health risks of diabetes, obesity and heart disease may not apply to office work nearly as much as the very common risk of musculoskeletal problems.  Clear examples are shown how a chair well designed for one kind of work can cause low back pain, as well as neck, shoulder, arm and hand pain when the type of work changes. Good spine posture is critical to resolve long-term trauma, and most ergonomics practice does not readily appreciate how easily good posture is lost in sitting.

Health Risks for Sitting ~ Leisure sitting has been linked to several disease categories

Sitting Has Bad Press! ~ Bloomberg/Huffington Post articles

Is Work Sitting Really a Problem? ~ Research says otherwise

Posture and the Low Back ~ An illustrative chart

Classic Ergonomic seated posture ~ Body is relaxed and torso is reclined, etc.

Work can change posture ~ A video

People get hurt at computers ~ Statistical research

Postural Muscles ~ The activity of deep postural muscles in the spine are linked to health

Deep muscle strength is linked to pain ~ Research papers

Slumping shuts off muscle ~ The deep muscles relax after 5 seconds of forward bend

We don’t feel slump ~ A video

Forearm support helps ~ Four research papers summarized

Thigh-Torso Angle does not show spinal posture ~ The simplest test for good spine posture is some slight movement at the low back

What’s Wrong With This Picture? ~ A look at problematic posture

“Perch” or Declined Sitting ~ The good and the bad

Section Three

Notes on Section Three: The Problem with Standing Work (For consultants)

If seating in general is considered the primary problem, moving to standing workstations ignores the reasons why different seated postures are problematic. Despite sales literature claiming to solve one problem, like low back pain, many of those products can cause additional musculoskeletal trouble when not used correctly. Medical research is cited to show how little standing workstations are used in the long-term, and where standing workstations may increase the risk of heart disease.

Standing—Good And Bad ~ The good and the bad

Work Postures By Effort ~ Work Postures By Effort

People Don’t Want To Stand ~ Three research papers summarized

Health Risks To Standing ~ Three more research papers summarized

Not Just The Lower Back … ~ Low back pain improved

Section Four

Notes on Section Four: The ActivSeating™ Process (For everybody)

This is the How-To section of the course that uses photographs and videos to demonstrate the sequence of the ActivSeating process in detail.  The key instructions show how to find good posture, and then how to sustain it easily. Attention is also drawn to the chair for critical details on chair adjustment. Six different chairs in common use are presented with a demonstration for their proper adjustment. Also included are research outcome measures from a Fortune 500 company.  This section is intended as a stand-alone guide for the end-user, or as a central component for the ergonomics consultant.

Pre- & Post-Comparison ~ 187 respondents reported frequency and severity of pain before and after consultation

Section Five

Notes on Section Five: Supporting Materials and Methods (For everybody)

This section will prove invaluable for the consultant: detailed observation skills are presented for both the body in the chair and for the chair itself, use of a commercial accelerometer program is introduced to provide objective strength data, and allow the process to work for alternative seated jobs like transportation and motorsports. Common hardware products are shown to modify the chair armrests and work surface height where needed. Alternative seating options are presented with the pros and cons of gymnastic balls, kneeling chairs, and sit-stand options. Independent care strategies for the low back and neck-shoulder-arm are provided, as well as case studies of common client presentations and solutions.
