คอมพิวเตอร์ทำให้กลายเป็นคนขี้โรค ป่วยโรคหัวใจ เบาหวาน และอ้วนง่าย

นักวิทยาศาสตร์มหาวิทยาลัยซิดนีย์ เมืองจิงโจ้ แสดงความเป็นห่วงใยผู้ที่ต้องนั่งทำงานหน้าจอคอมพิวเตอร์ วันหนึ่งเป็นเวลานานๆ จะพากันกลายเป็นคนขี้โรคกันหมด เพราะเหตุว่าจะเจ็บไข้เป็นโรคหัวใจ เบาหวาน และอ้วนได้ง่าย

พวกเขาพบในการศึกษาว่า แม้ว่าพนักงานตามสำนักงานหลายแห่ง จะพยายามป้องกันไว้แล้ว ด้วยการใช้เก้าอี้ที่ออกแบบพิเศษ คำนึงถึงสภาพและประสิทธิภาพในการทำงานของคนงาน หรือแม้แต่ยืนทำงาน ก็ยังไม่วายที่จะเกิดอาการปวดหลัง ปวดคอ ข้อมือและไหล่ อยู่ดี

หัวหน้านักวิจัยอ้างว่า เพราะมีการใช้คอมพิวเตอร์กันมากขึ้น จึงทำให้แทบจะลบล้างความพยายามในการออกแบบเครื่องคอมพิวเตอร์ทั่วไป ตั้งแต่สมัยยุคทศวรรษก่อนๆ ให้ดีขึ้นและใช้สะดวกขึ้นไปจนหมดสิ้น ยังคงมีเสียงร้องเรียนอาการปวดหลัง ปวดไหล่มากขึ้นอยู่ดี.

Corporate high flyers: the unintended victims of the paperless office

29 August 2012

Office workers from all professions are experiencing unprecedented levels of neck, back, shoulder and arm pain as an unintended consequence of the paperless office, according to new University of Sydney research.

The study, published in this month’s edition of WORK: a Journal of Prevention, Assessment and Rehabilitation, found that moves since the 1980s to improve occupational health and safety and workstation design may have been completely reversed by changing work practices, including longer duration of computer work and less task variability.

The survey of more than 900 office workers found a direct correlation between the amount of time spent at a computer and the likelihood of experiencing musculoskeletal pain over a 12 month period.

Eighty-five percent of people who spent more than eight hours a day working with a computer experienced neck pain, 74 percent reported shoulder pain and 70 percent reported lower back pain.

“Since I started assessing offices for computer workstation safety in the early 1980s, I’ve noticed massive changes with the amount of computer work now performed by office workers, particularly professional and executive workers,” says Karin Griffiths, lead author of the research and doctoral candidate in the University’s Faculty of Health Sciences.

“Better workstation design, seating and health education has not resulted in any observable decrease in the number of office workers reporting pain over the last 20 to 30 years. In fact, recent research shows that prolonged sitting and the lack of physical activity associated with computer work is the main problem, and may be contributing to cardiovascular disease, diabetes and obesity along with musculoskeletal pain,” she says.

As part of her research, Griffiths, who also works as an occupational health and rehabilitation physiotherapist, compared office workers in different occupations, the number of hours of computer-based work they reported, and whether they experienced pain or other health problems.

While musculoskeletal symptoms affect all office workers, those who spent more time at their computers, including professionals and senior executives, were the hardest hit.

“Though traditionally it was predominantly non-professional employees such as secretaries, data entry and call centre workers who were subjected to long hours of computer-based work, now all office workers, including more highly skilled or senior employees such as architects and engineers, tend to spend a longer day in front of the computer and so are more likely than ever before to experience musculoskeletal pain,” Griffiths says.

“Non-professional groups have generally been the focus of research in this area, so I felt that the literature was neglecting managers and higher level employees. Anyone who works in an office knows that whatever your occupation and level of seniority, you’re likely to be spending long hours every day at a computer.”

According to Griffiths, with long computer-based work here to stay, the key to preventing musculoskeletal pain among office workers lies in changing workstation design and how we do our jobs so that we are obliged to stand and walk more often during work hours.

Activity-based workplaces, in which computer and non-computer work tasks can be completed at a variety of seated and standing workstations, are an example of an encouraging movement towards more mindful office design.

Other ways of reducing the risk of musculoskeletal symptoms at work could include discouraging internal emails on the same floor to encourage employees to walk to their colleagues instead, ‘kitchen table’ type meetings that encourage people to stand and walk, or work systems that require frequent standing breaks, such as placement of telephones on a standing bench.

“Offices need to be designed to stimulate physical activity among employees. We need to start including standing workstations and encourage more standing and walking within offices as a matter of course for everyone who uses a computer for most of their day,” Griffiths says.

ติงทำงานด้วยสมาร์ทโฟนทำเจ็บป่วย

สมาคมกายภาพบำบัดในอังกฤษออกรายงานชิ้นใหม่ เตือนว่ามนุษย์เงินเดือนทั้งหลายกำลังกลายเป็น “ทาสหน้าจอ” หลังพบว่าพนักงานบริษัทจำนวนมากยังคงทำงานหลังเวลางาน โดยใช้สมาร์ทโฟน หรืออุปกรณ์คอมพิวเตอร์พกพาต่างๆ
งานวิจัยพบว่า ผู้คนได้ทำงานเพิ่มขึ้นเป็นเวลาเฉลี่ย 2 ชั่วโมงทุกวันระหว่างเดินทางไป-กลับ และเมื่อถึงบ้านแล้ว

เหตุที่คนจำนวนมากกลายเป็น “ทาสหน้าจอ” เป็นเพราะแรงกดดันในที่ทำงาน แม้บางคนบอกว่าการเอางานกลับไปทำที่บ้านในตอนค่ำช่วยลดความเครียดได้
ผลการศึกษาเจ้าหน้าที่สำนักงานกว่า 2,000 คนพบว่า ในเวลากลางวันคนส่วนใหญ่ใช้เวลาอยู่หน้าจอคอมพิวเตอร์นานเกิน 6 ชั่วโมง จากนั้นระหว่างเดินทางกลับบ้านก็ยังทำงานต่อด้วยสมาร์ทโฟนหรืออุปกรณ์อื่นๆ

ทางสมาคมบอกว่า การโหมงานหนักทำให้เกิดปัญหาสุขภาพได้ และการใช้ท่วงท่าไม่ถูกต้องขณะใช้สมาร์ทโฟนก็ทำให้เกิดอาการปวดหลังหรือปวดคอได้
รายงานแนะว่า นายจ้างควรชักชวนให้พนักงานหยุดพักเป็นระยะ และเข้าร่วมกิจกรรมต่างๆ ในระหว่างวัน

ดร.เฮเลนา จอห์นสัน ประธานสมาคม บอกว่า ผลการสำรวจนี้สร้างความวิตกแก่บรรดานักกายภาพบำบัด ซึ่งได้เห็นอยู่ทุกวันว่าการนั่งใช้อุปกรณ์คอมพิวเตอร์ไม่ถูกหลักสรีรศาสตร์ และการละเลยหลักการทำงานที่ดี ได้ทำให้ผู้คนต้องเจ็บป่วยไม่สบาย

“ถ้าเอางานไปทำที่บ้านบ้างเป็นบางครั้งในระยะสั้นๆ ก็ไม่เป็นไร แต่ถ้าทำเป็นกิจวัตรประจำวันในยามค่ำก็อาจทำให้เกิดอาการปวดหลังหรือปวดคอได้ รวมทั้งอาการเจ็บป่วยที่เกี่ยวกับความเครียด”

“อาการเหล่านี้จะเกิดขึ้นเมื่อใช้อุปกรณ์พกพา และไม่ระวังเรื่องท่วงท่าในการทำงาน” ดร.จอห์นสันบอก “ถ้ารู้สึกเครียด จงพูดคุยกับนายจ้าง”.

Smartphone users ‘risking health’ with overuse of devices

18 June 2012

People are risking their health by working on smartphones, tablets and laptops after they have left the office, according to the Chartered Society of Physiotherapy.

It says people have become “screen slaves” and are often working while commuting or after they get home.

The society said poor posture in these environments could lead to back and neck pain.

Unions said people needed to learn to switch off their devices.

An online survey, of 2,010 office workers by the Society found that nearly two-thirds of those questioned continued working outside office hours.

The organisation said people were topping up their working day with more than two hours of extra screentime, on average, every day.

The data suggested that having too much work and easing pressure during the day were the two main reasons for the extra workload.

‘Posture’

Brendan BarberTrades Union Congress

The chairwoman of the Chartered Society of Physiotherapy, Dr Helena Johnson, said the findings were of “huge concern”.

She said: “While doing a bit of extra work at home may seem like a good short-term fix, if it becomes a regular part of your evening routine then it can lead to problems such as back and neck pain, as well as stress-related illness.

“This is especially the case if you’re using hand-held devices and not thinking about your posture. Talk to your employer if you are feeling under pressure.”

The general secretary of the Trades Union Congress, Brendan Barber, said: “Excessive work levels are not good for anyone. Overworked employees are not only unlikely to be performing well at work, the stress an unmanageable workload causes is also likely to be making them ill.

“By the time someone is so overloaded they constantly feel the need to put in extra hours every night of the week at home, things have clearly got out of hand.

“Individuals who find themselves unable to leave their work in the office should talk to their managers and learn to switch off their smartphones.”

The ‘growing pains’ that could cripple you for life

The ‘growing pains’ that could cripple you for life
By ISLA WHITCROFT
UPDATED: 00:14 GMT, 30 November 2010

Paul Curry’s teenage years were blighted by what doctors insisted were growing pains. Not just the odd sharp stab or ache that many youngsters suffer, but attacks that were so severe he was often bedridden for days.
‘The pain was dull, gnawing deep inside both hips,’ says Paul, 28, from Durham. ‘It was excruciating.

‘The first time it happened I was 13 and mad about sport, particularly rugby. I assumed — as did my parents — it was growing pains or a sporting injury and so would go away.’

At risk: Young males are most likely to suffer from Ankylosing Spondylitis(AS), a progressive rheumatic disease that causes inflammation around joints

Unfortunately, over the next few years not only did the pain worsen, but the attacks became more frequent and lasted longer.

‘Sometimes I could cope by taking painkillers, but other times I’d be in bed for days, screaming with pain,’ says Paul.

Over the next few years, his parents took him to see his GP several times. He diagnosed growing pains and said it was ‘something Paul would grow out of’.

A consultant orthopaedic ­surgeon, to whom Paul was referred privately at the age of 16, then pronounced he was suffering from Sherman’s disease, a mild condition that causes a slight curvature of the upper spine.

‘He said that by the time I was 21 I’d have grown out of it. In the meantime, I was to keep taking painkillers,’ he says.

Sadly, Paul, from Durham, didn’t have Sherman’s disease, but Ankylosing Spondylitis (AS), a progressive rheumatic disease that causes inflammation around bone joints and ligaments.

Left untreated, this causes bone erosion, which stimulates the immune system into a healing process. This, in turn, produces an overgrowth of bone, which leads to the fusion of bones such as the spine and hips and eventually immobility. The damage is irreversible.

Some 400,000 Britons are affected by AS, with symptoms usually appearing between the ages of 25 and 34 — though ­teenagers and older people can be affected.

Unfortunately, like Paul, many sufferers are mis-diagnosed — with devastating consequences.

Today, at 28, Paul is racked with constant pain. The discs in the lower half of his spine have fused, as have his hip and pelvic joints.

Three vertebrae at the top of his neck are also affected and this once super-fit teenager counts himself lucky if he walks without using a stick.
At night, his joints stiffen and spasm and he is dependent on a daily dose of morphine.

Late diagnosis: Paul Curry’s crippling condition was not spotted until his 20s

Not surprisingly, in the past, the condition has left Paul feeling depressed.

‘I still get distressed about what might have been had I been properly diagnosed early on,’ says Paul who, after getting a degree in business management, had to move back in with his parents because he is often confined to bed for days at a time.

Despite spending thousands of pounds on specialists over the years, Paul wasn’t diagnosed until he was 26, when an astute physiotherapist recognised his symptoms and advised him to see a rheumatologist.

‘She examined me and said she was almost certain I had AS,’ says Paul.

‘Blood tests and an MRI scan confirmed this. It was a scary diagnosis, but an utter relief that at last I knew what I was dealing with.’

Shockingly, the average delay in diagnosing the condition is ten years, according to a survey for the National Ankylosing Spondylitis Society (NASS).

‘There is a lack of awareness of the condition and how to distinguish the symptoms from other causes such as back pain,’ says Dr Andrew Keat, consultant rheumatologist at Northwick Park Hospital, Harrow, Middlesex, and a specialist in AS.

‘Unfortunately, the very people who suffer most from the ­condition — young males — are also the ones who tend to be the most active,’ he says.

‘Therefore, it’s easy to write off their symptoms as being a sporting injury or even just growing pains.’

The main distinguishing ­symptom is inflammatory joint pain, which comes on slowly and usually occurs in the lower back or hips. Crucially, it improves with exercise and worsens with inactivity, meaning it’s often severe at night.

‘These symptoms should be a red light to your GP that ­inflammation is occurring,’ says Dr Keat. ‘If anti-inflammatories don’t help after a few weeks, the symptoms need further investigation by a rheumatologist.’
There is no one simple test, says Dr Keat.

‘We look at family history, symptoms, make a physical examination and take blood tests for signs of inflammation. X-rays rarely show the condition so an MRI scan is essential,’ he says.

Ironically, once the condition is diagnosed, treatment is ­usually effective — with anti-inflammatories such as ibuprofen and exercise, as movement discourages the fusion process.

Exercise can make a significant difference, as Liz Ledger proves. Now 28, she had severe hip pains from the age of 17; these were also blamed on growing pains.

‘I lost count of how many health professionals I saw,’ says Liz, a sales and marketing ­manager from Bristol.

However, she worked out that the pain receded when she ­exercised and over the years she has devised a routine that kept it manageable.

But by her mid-20s the pain was increasingly severe. Finally, in October 2007, she suffered a flare-up that left her bed-bound.

‘I dragged myself to the GP and insisted that I wasn’t ­leaving without a referral to a rheumatologist.’

An MRI scan and blood test confirmed AS; her first four ­vertebrae had fused and there were signs of fusion in the hips and pelvic joints.

Her condition is being managed by anti-inflammatories and pain-killers. She does cycle classes, body conditioning and gentle running six days a week.
‘It’s a commitment, but it means the difference between mobility and immobility,’ she says.

‘AS can be a devastating ­condition, but one positive thing is that the sufferer can actually help themselves,’ says Jane Skerrett of the NASS.

‘The earlier a patient gets on to a suitable exercise regimen the better.’
The charity has launched an exercise guide, developed by a rheumatologist and physiotherapists, that contains a full ­fitness programme as well as advice.

Despite his pain, Paul makes sure he always does gentle stretching and walking. And ­having recently married, he remains optimistic and is keen to start a family.

Liz, who was diagnosed earlier in the disease cycle, is also upbeat. ‘I recently completed a half-marathon,’ she says.

‘Now I’m back at work and have a social life. Exercise has given me control of this disease.’
