A healthy person can develop a pressure sore in 6 to 12 hours. While 63 percent of patients who sit for unlimited periods of time develop pressure sores, only 7 percent who sit for maximum periods of 2 hours develop pressure sores. Although there are several intrinsic (within the body) risk factors for pressure sores, there is only one extrinsic (coming from outside the body) risk factor for pressure sores: Pressure. Cushions can be used to reduce external pressure. Studies show it is best to change posture frequently and use a medium density, open-cell foam cushion that envelops the buttocks to minimize external pressure.
A Healthy Person can Develop Pressure Sores in 6 – 12 Hours
“A healthy individual can develop pressure sores in six to twelve hours if left undisturbed in the same position, (Hargast, T., 1979; Staggs, K., 1983; Torrence, C., 1981).” (2)

Discussion of ergonomics and ergonomic design to minimize risk factors for the development of musculoskeletal disorders (MSDs) and cumulative trauma disorders (CTDs). Also includes discussion of OSHA Standard 29 CFR Part 1910 to explain the benefits of prevention of MSDs and CTDs to employers and employees. Prevention of musculoskeletal pain is also relevant to individuals who spend a lot of time social networking, gaming, or blogging.
What is Ergonomics?
Ergonomics is the science of fitting jobs to people, including anatomy, physiology, and psychology.
What is Ergonomic Design?
Ergonomic design is the application of this body of knowledge to the design of the workplace (i.e., work tasks, equipment, environment) for safe and efficient use by workers.
Musculoskeletal Disorders (MSDs)
Up to 85 percent of the population will suffer from musculoskeletal pain.
Ergonomic Design for Prevention of MSDs
Musculoskeletal pain is a leading cause of health-care visits, particularly in primary care, sick absenteeism, and early pensions. . .Thus preventing disability and high-cost cases may result in large economic savings (2).
Until prevention is granted more resources, programs need to be relatively cheap; and this suggests incorporating them into existing practice routines (2).

Hemorrhoids are much more prevalent in the Western World compared with “Third World Countries.” Hemorrhoids are associated with constipation, heavy physical work, and the effects of erect posture. Hemorrhoids are common during pregnancy. In addition to hemorrhoids, industrialized countries are at an increased risk for colorectal cancer. If you suspect you have hemorrhoids, always talk to your doctor. Do not self-diagnose!
Hemorrhoids are one of the most frequent problems people in westernized countries face. There are estimates of up to 75 to 90 percent occurrence rates of hemorrhoids in the U.S. population (1, 2, 3, 4, 5).

Frequent forward bending while sitting or standing is a risk factor for low back pain. The Buttpillow-Original (TM) and Butpillow-Ergo (TM) are embodiments of the Patented “Ergonomic Seating Cushion” which can minimize risk factors for the development of low back pain while sitting.
LOW BACK PAIN FROM FORWARD BENDING
In this study, a motion analysis system was used to measure the amount and velocity of lumbar spine and hip motion during forward bending.
The authors begin by citing the following previous findings:
Epidemic of Low Back Pain
“Disorders of the low back have reached epidemic proportions, (DeRosa, C.P., 1992).”
Lost Work Time | Workers’ Compensation Claims from Low Back Pain
“Epidemiologic studies show that billions of dollars are spent annually on the problem of low back pain, which is one of the most commonly-cited problems for lost work time in industry and Workers’ Compensation claims, (Chase, J.A., 1992; Frymoyer, J.W., 1988; and Pope, M.H., et al., 1991).”
Frequent Forward Bending Causes Low Back Pain
“Researchers have shown an association between frequent forward bending and low back pain, (Berquist-Ullman, M., et al., 1977; Magora, A., 1973; Mellin, G., 1986; Punnett, L, et al., 1991; Svensson H.O., et al., 1989; Videman T., et al., 1989).”
