Dr. Jan Lefkowitz, a New York City chiropractor, says that body pain, herniated discs, nerve problems, and painful joints are the direct result of long office hours. Dr. Lefkowitz continues that when you’re sitting the spine is under a lot of pressure.
Kelly McGonigal, Ph.D. a health psychologist at Stanford University and leading expert in neck and back pain says that work is putting a huge mental and physical stress on our bodies, and around 80% of Americans will experience chronic pain in their lifetime as a result.
John Edwards Swartz MD FACP and Sheldon Margen MD and the editors of the UC Berkley Wellness Letter state that sitting and standing put considerable pressure on the lower back, standing exerts five (5) times more pressure than lying down and sitting, surprisingly, is even more strenuous. In fact, researchers believe that poor sitting posture is a major contributor to lower back pain.
Gail M. Jensen, in the journal of American Physical Therapy Association, indicated that standing causes about four (4) times as much pressure in the third lumbar disk versus lying supine, sitting causes about 5.5 times as much pressure in the third lumbar disk versus lying supine, and sitting while bent forward 20 degrees causes about 7.5 times as much pressure in the third lumbar disk versus lying supine.
Kenneth K. Hansraj, MD Chief of Spine Surgery, New York Spine Surgery & Rehabilitation Medicine in the Assessment of Stresses in the Cervical Spine caused by Posture and Position of the Head, stated that compared with neutral, flexing the head forward at 45 degrees and 60 degrees caused about 5 and 6 times the force to the cervical spine, respectively, when compared to the neutral position.
Bonnie Berkowitz and Patterson Clark, The health hazards of sitting, published in The Washington Post January 20, 2014, wrote that we know sitting too much is bad, and most of us intuitively feel a little guilty after a long TV binge. But what exactly goes wrong in our bodies when we park ourselves for nearly eight hours per day, the average for a U.S. adult? Many things, say four experts, who detailed a chain of problems from head to toe, Heart Disease, Overproductive Pancreas, Foggy Brain, Strained Neck, Colon Cancer, Mushy Abs, Tight Hips, Limp Glutes, Poor Circulation in Legs, Sore Shoulders and Back, Inflexible Spine, Disk Damage, and Soft Bones.
Seth S. Leopold M.D. Professor, UW Orthopaedics Sports, says that typical symptoms of hip arthritis are pain in the groin, thigh, or buttock; the pain is generally worse with weight bearing (walking, standing) or twisting.
Ryan Nunley, MD, Washington University Physicians, says that groin pain is a common complaint in people who have hip problems. Many times people think their groin pain is due to a pulled muscle, but it can be frequently due to irritation inside the hip joint. Groin pain that comes from the hip typically develops slowly over time without specific injury or trauma. The pain is worse when the hip is flexed, for example, while sitting in a low chair or while driving.
Rachel Grumman Bender, at Fast Company, states that: Desk Job Danger No. 1: Lower Back Pain, Desk Job Danger No. 2: Wrist Strain, Desk Job Danger No. 3: Neck and Shoulder Pain, Desk Job Danger No. 4: Eye Strain, and Desk Job Danger No. 5: Tight Hips.
According to Knee Pain Explained, the second most common cause of knee pain is Chondromalacia Patella and is aggravated by sitting for long periods.
According to the Cleveland Clinic, back pain and related symptoms rank among the second most frequent medical complaints. Disability from low back pain is second only to the common cold as a cause of lost work time and is the most common cause of disability in people under 45 years of age. The Cleveland Clinic also indicates that during flexion that occurs with sitting, intradiscal pressure is greatest and the disc exerts pressure on the thinnest, least supported area of the surrounding ligament known as the annulus fibrosus. As a result, the disc can herniate. Mechanical low back pain is usually aggravated by static loading of the spine (prolonged sitting and standing), long levered activities (e.g. vacuuming) or levered postures (bending forward). According to the Cleveland Clinic, in the United States, the lifetime prevalence of back pain is approximately 80%. The one year prevalence rate of 15% to 20%, the highest prevalence is in the 45 to 64 age group. Applying this to the US population, there are approximately 310 million people in the US, therefore approximately 248 million people will experience back pain in their lifetime. Also, 37.2 million to 49.6 million people will have back pain for at least one year.
Dr. Jason Freedman, a specialist in orthopedic surgery, stated, “Standing desk aficionados tend to experience more pain in the lower back, legs, and feet.”
Dr. Rob DeStefano, a chiropractor in private practice in New York City, said “Yes, standing too much can become uncomfortable and irritate the hips or back if they have prior injuries.”
CUErgo, Sitting and Standing at work.
At Agency Central, the recruitment agency directory, in Standing vs. Sitting: Which is Better? It is stated that there are countless studies on how sitting for long periods is slowly ‘killing you’ and how we should treat it as a serious health threat. Yet people who are standing up every day are left with aches in the muscles (especially leg muscles), pain in their joints and spinal problems.
