But do you know who else suffers from the effects of MSDs — you! According to the Bureau of Labor Statistics, MSDs account for 33 percent of lost day workplace injuries and illnesses. Of even greater concern to employers is the fact that typically MSDs result in longer periods away from the job than do more traumatic injuries. Carpal tunnel syndrome (CTS), for example, results in an average of 32 lost days, while fractures and amputations result in 30 lost days, repetitive motion injuries result in an average 22 lost days, and falls to a lower level result in 15 lost days.
From an economic perspective, MSDs account for one out of three dollars spent on workers’ compensation, at a cost of approximately $20 billion per year. In addition, indirect costs, such as those associated with hiring and training replacement workers, can be up to ten times as expensive as direct costs.
The following questions and answers will help you identify some of the causes of MSDs and provide some valuable insight on adjustments you can make to reduce the frequency and severity of these debilitating workplace injuries.
Q: What MSD risk factors should I be looking for in the work environment?
A: Repetitive, forceful, or prolonged exertions of the hands; frequent or heavy lifting, pushing, pulling, or carrying of heavy objects; prolonged awkward postures; and vibration contribute to MSDs. Jobs or working conditions that combine risk factors increase the risk for developing musculoskeletal problems.
Q: What steps can I take to reduce MSDs?
A: According to the National Institute for Occupational Safety and Health, a three-tiered hierarchy of controls is widely accepted as an intervention strategy for controlling MSDs. The three tiers are as follows:
- Reducing or eliminating potentially hazardous conditions using engineering controls
- Changing work practices and management policies (administrative controls)
- Using personal equipment
Q: What type of engineering controls are recommended?
A: The preferred approach to prevent and control MSDs is to consider the capabilities and limitations of the workforce when designing workstation layout, selection and use of tools, and work methods. A good match (meaning that the job demands minimize undue stress and strain to the working population as a whole) helps ensure a safe work situation. On the other hand, the presence of MSD risk factors represents departures from this goal and would indicate the need for control measures.
Q: What type of administrative controls are recommended?
A: Administrative controls are management- dictated work practices and policies to reduce or eliminate exposures to ergonomic risk factors. Administrative control strategies include changes in job procedures, such as scheduling more rest breaks, rotating workers through jobs that are physically tiring, and training workers to recognize ergonomic risk factors and to learn techniques for reducing stress and strain while performing their work tasks.
Q: How can personal protection equipment reduce MSDs?
A: Personal protection equipment (PPE) generally provides a barrier between the worker and the hazard source. Gloves are an example of an ergonomic PPE.
Q: Does my company need an ergonomics program?
A: YES! The extent of the program that’s appropriate for your organization depends on the exposures your employees face. Some signs that may indicate the need for a more formal program include:
- Company OSHA Form 300 logs or workers’ compensation claims show cases of MSDs
- Worker complaints of undue strain, fatigue, pain or discomfort that does not go away after a night of rest
- Workers making frequent trips to medical professionals due to physical aches and pains
- High turnover in certain departments and positions
- Jobs that involve repetitive and forceful exertions; frequent, heavy or overhead lifts; awkward work positions; temperature extremes; or use of vibrating equipment
- Cases of MSDs found among similar businesses in the industry
Q: Who can I count on to help reduce the likelihood of MSDs in my workplace?
A: Simple, Count on EMC. This issue of Loss Control Insights is packed with helpful tips. Even more information is available online at emcinsurance.com or from an EMC risk improvement professional.
A group of conditions that involve the nerves, tendons, muscles, and supporting structures (such as intervertebral discs). They represent a wide range of disorders, which can differ in severity from mild periodic conditions to those which are severe, chronic and debilitating.
Think computer use causes carpal tunnel syndrome? Think again. According to a Harvard Medical School study, carpal tunnel syndrome may occur because of heredity, body weight, fracture, or even pregnancy.
Recent research has found that heavy computer use — up to seven hours a day — does not increase risk for carpal tunnel syndrome. However, improper computer use and other workplace conditions can contribute to a type of disorder known as repetitive stress injury. Carpal tunnel syndrome is not a repetitive stress injury, though it is often incorrectly described as one, states the Harvard report.

According to a new study from Canada’s Institute for Work and Health, female college graduates employed in a full-time job are most likely to develop repetitive strain injury such as wrist tendonitis or certain kinds of lower back pain.
The most common type of repetitive strain injury identified in the study were in the wrist or hand (37%), shoulder or upper arm (20%), elbow or lower arm (15%) and lower back (11%).
The report concluded that while there are programs in place to prevent repetitive stress injury, more attention needs to be focused on convincing employers to take action to prevent work-related repetitive strain injury.

First The Good News:
Workplace Injury And Illness Rates Are Down
A total of 4.3 million injuries and illnesses were reported in private industry during 2004 (latest data available), down from 4.4 million in 2003. These cases occurred at a rate of 4.8 cases per 100 equivalent full-time workers, according to the Survey of Occupational Injuries and Illnesses by the Bureau of Labor Statistics. This was a decline from the rate of 5.0 cases per 100 equivalent full-time workers reported by the Bureau for 2003 and resulted from a 2.5 percent decrease in the number of cases reported combined with a 1.6 percent increase in the number of hours worked.
Goods-producing industries as a whole had an injury and illness rate of 6.5 cases per 100 equivalent full-time workers, while service-producing industries as a whole had a rate of 4.2 cases per 100 equivalent full-time workers. Both of these rates declined by 0.2 cases per 100 equivalent full-time workers from the rates reported for 2003. Among all private industry sectors, only the utilities sector experienced a significant increase in the injury and illness rate, rising from 4.4 cases per 100 equivalent full-time workers in 2003 to 5.2 cases in 2004.
Now For The Bad News:
Workplace Injuries Remain Costly To Employers
While employers have implemented programs to cut the number of workplace injuries, accidents continue to impact the financial performance of organizations throughout the country. Although a recent national study revealed that the rate of growth in the cost of the most serious workplace injuries slowed significantly, the financial impact of those injuries remains a problem. In 2003, for example, employers spent $50.8 billion on wage payments and medical care for workers hurt on the job.
What type of injury has the greatest financial impact? According to this study, overexertion represented 26.4 percent of total reported injuries, costing employers $13.4 billion. Other costly injuries included falls on the same level, representing 13.7 percent of injuries at a cost of $6.9 billion; bodily reaction injuries, representing 10.2 percent at a cost of $5.1 billion; and falls to a lower level, representing 9.0 percent of reported losses, costing employers $4.6 billion.

What body part is the most frequently affected by workplace injuries? According to the Bureau of Labor Statistics, more than one million workers suffer back injuries each year; and back injuries account for one of every five workplace injuries or illnesses. The financial impact is just as alarming. One-fourth of all compensation indemnity claims involve back injuries, costing American industries billions of dollars.
Lifting Is The Culprit. Effective Controls Are The Answer.
Although no approach has been found for totally eliminating back injuries caused by lifting (the major cause of injuries to the lower back), a substantial portion can be prevented by implementing the following controls:
- Installation of mechanical aids such as pneumatic lifts, conveyors and/or automated materials handling equipment
- A reduction in the size or weight of the object lifted
- Adjusting the height of a pallet or shelf to avoid strenuous lifting which occurs below knee height or above shoulder height
- Training employees to utilize lifting techniques that place minimum stress on the lower back
- Physical conditioning or stretching programs to reduce the risk of muscle strain
- Strength testing of workers can prevent up to one-third of work-related injuries by discouraging the assignment of workers to jobs that exceed their strength capabilities
Count On EMC To Help You Reduce Back Injuries
You can learn more about reducing back injuries by logging in to emcinsurance.com. Click loss control for access to videos, technical manuals and other resources that can help train your employees about safe lifting and other techniques to reduce the likelihood of back injuries and other MSDs.
The following safe lifting principles from the Washington State Department of Labor can reduce the risk of back injury.
- Size up the load, making certain you can lift it safely.
- Get as close to the load as possible before lifting.
- Keep the load as close to your body as possible.
- Make sure your footing is secure.
- Do not twist while lifting.
- Lift smoothly and slowly.
- Organize the work to avoid lifting from the floor or above shoulder level.
- If you have a lot of lifting to do during the day, try not to do it all at once.
- Use the same principles when lowering or placing the load after lifting.
- Try to avoid carrying a load more than 10 feet without getting mechanical assistance.
Not all jobs are created equal when it comes to the risk of work-related back pain and injury. Members of the American Chiropractic Association (ACA) rated the jobs they considered to be most “back-breaking:”
- Heavy truck and tractor-trailer drivers
- Construction workers
- Police officers
- Shingle roofers
- Delivery drivers
- Nursing home workers
- Auto mechanics
The ACA suggests the following to limit back strain:
- Maintain proper posture
- Wear comfortable, low-heeled shoes
- Alternate tasks that use different muscle groups
- Take periodic stretch breaks
- Lift with the knees, keep the object close to the body, and do not twist when lifting
Concussions can happen to any athlete in any sport. More than 300,000 people sustain sports- and recreation-related concussions every year in this country. Coaches, athletic directors and trainers play a key role in helping to prevent concussions and in managing them properly if they occur.
Concussions are a type of traumatic brain injury caused by a blow or jolt to the head that can range from mild to severe and can disrupt the way the brain normally works.
To reduce the frequency of this type of injury, the Centers for Disease Control and Prevention (CDC) has developed a tool kit for coaches titled, “Heads Up: Concussion in High School Sports.” The kit contains practical, easy-to-use information, including a video and DVD, a guide, wallet card, and clip board sticker; posters, fact sheets for parents and athletes (in English and Spanish); and a CD-ROM with downloadable kit materials.
You can order a free copy of this kit by contacting the National Center for Injury Prevention and Control at www.cdc.gov.
