Musculoskeletal Disorders (MSDs): Understanding the Risks, Costs, and Prevention Strategies

What is a “musculoskeletal disorder” (MSD)?

A musculoskeletal disorder (MSD) is an injury or condition that affects the muscles, bones, joints, tendons, ligaments, nerves, or other connective tissues. These disorders can develop gradually from repetitive movements and physical strain or occur suddenly from a workplace injury, often causing pain, reduced mobility, and difficulty performing everyday tasks.

What Is the Relationship Between Work and Musculoskeletal Disorders?

The relationship between work and musculoskeletal disorders (MSDs) is well established. In fact, the Centers for Disease Control and Prevention (CDC) and the National Institute for Occupational Safety and Health (NIOSH) published a comprehensive review of research on work-related musculoskeletal disorders (WMSDs) as early as 1997. Their findings showed that several workplace activities are directly associated with the development of musculoskeletal disorders affecting the neck, shoulders, elbows, hands, wrists, and back.

Key physical workplace risk factors include:

• Heavy materials handling
• Regular exposure to whole-body vibration
• Repeated overhead work
• Working with the neck consistently flexed
• Performing repetitive, forceful tasks

Beyond physical demands, several workplace and environmental factors also contribute to the development of musculoskeletal disorders, including:

• Excessive cold or heat
• Noise
• High work demands
• Long working hours
• Lack of breaks
• Harassment or discrimination
• Low job satisfaction

These physical and psychosocial factors create emotional stress, which can increase muscle tension and the total load on the musculoskeletal system. Together, these changes contribute to the development of work-related musculoskeletal disorders (WMSDs) and increase the risk of chronic musculoskeletal pain.

More broadly, a lack of workplace policies that promote healthy, non-aggravating work conditions also contributes to the development of musculoskeletal disorders. In workplaces without adequate ergonomic controls, workers are more likely to report discomfort and musculoskeletal pain, which can eventually lead to work absences, reduced productivity, and a higher risk of workplace injuries.

What Personal Factors Contribute to Musculoskeletal Disorders?

In addition to workplace characteristics, personal factors also play a significant role in the development of musculoskeletal disorders (MSDs). Personal health conditions such as obesity, smoking, physical deconditioning, poor nutrition, alcohol consumption, and age can all increase an individual's likelihood of developing a musculoskeletal disorder.

Proper body mechanics and lifting techniques are equally important. When workers do not know how to apply good ergonomic practices during their daily tasks, poor body mechanics and unsafe lifting habits can increase the risk of work-related musculoskeletal disorders (WMSDs). Likewise, if an employee's physical abilities do not match the physical demands of the job, the likelihood of developing musculoskeletal disorders increases.

Ignoring minor aches, discomfort, or early symptoms can also allow a musculoskeletal disorder to progress into a more serious injury that results in lost work time. Similarly, if employees return to work too soon after an injury or illness, they may not be physically ready to perform their job safely, increasing the risk of another musculoskeletal injury or recurrent work-related musculoskeletal disorder.

Musculoskeletal Disorders Are Caused by Both Workplace and Personal Factors

When musculoskeletal disorders (MSDs) occur, it's tempting to blame either the job or the worker in isolation, depending on one's perspective. We often hear comments such as:

"Well, it's no surprise that he was injured. That job is just too hard."

Or

"Well, given her weight, what did she expect?"

In reality, work-related musculoskeletal disorders (WMSDs) and musculoskeletal pain are rarely caused by a single factor. Instead, they typically result from a complex combination of workplace risk factors such as repetitive tasks, heavy physical demands, and poor ergonomics and personal factors, including overall health, physical conditioning, and lifestyle. 

Understanding this interaction is essential for developing effective strategies to prevent musculoskeletal disorders and reduce workplace injuries.

Just as the causes of musculoskeletal disorders are multifactorial, prevention requires more than a single solution. It begins with building a strong workplace safety culture where employee health and injury prevention are valued as highly as productivity. 

When organizations consistently prioritize safety through their policies, leadership, and daily practices, employees are more likely to adopt safe work habits and follow ergonomic best practices. As the saying goes, actions speak louder than words.

What Is a Comprehensive "Hire-to-Retire" Musculoskeletal Disorder Prevention Program?

There is no single solution for preventing musculoskeletal disorders (MSDs). Research consistently shows that reducing work-related musculoskeletal disorders (WMSDs) requires a comprehensive, multifactorial approach that addresses employees throughout their entire employment lifecycle from hiring through retirement.

However, our experience working with organizations across the United States shows that many employers still rely almost exclusively on training employees in proper lifting techniques and body mechanics. In many cases, this training is delivered through generic online or classroom courses, leaving employees to apply the information on their own.

Unfortunately, this limited approach rarely succeeds in preventing musculoskeletal disorders.

Organizations that combine hiring practices, workplace ergonomics, employee training, early intervention, and return-to-work programs consistently experience fewer work-related musculoskeletal disorders and lower injury rates.

Action 1: Conduct Job Analysis and Pre-Hire Physical Abilities Testing (PAT)

What It Is

Preventing musculoskeletal disorders (MSDs) begins before an employee starts work. Hiring individuals whose physical abilities match the physical demands of the job significantly reduces the risk of work-related musculoskeletal disorders (WMSDs).

What to Include

A comprehensive prevention program should include:

• Job Analysis: Identify and document the essential physical requirements of each role, including lifting, carrying, pushing, pulling, reaching, bending, climbing, and repetitive movements.
• Job-Specific Physical Abilities Testing (PAT): Evaluate whether candidates can safely perform the job's physical demands before they begin work.
• Legal Compliance: To comply with the Equal Employment Opportunity Commission (EEOC) and the Americans with Disabilities Act (ADA), Physical Abilities Tests (PATs) must be based on objective, job-specific requirements. A thorough job analysis provides the foundation for developing legally defensible assessments.

Why It Matters

Many employers rely on written job descriptions when developing hiring assessments. However, job descriptions often fail to reflect the actual physical demands of the role because equipment, workflows, staffing levels, and production expectations change over time. A current Job Analysis is essential for developing valid, job-specific Physical Abilities Tests.

Action 2: Implement Ramp-In and Work Acclimation for New Employees

What It Is

Many employees enter physically demanding jobs without being adequately conditioned for the work. Even if they successfully complete a Physical Abilities Test (PAT), they may not yet be prepared to sustain a full workday involving lifting, bending, reaching, squatting, climbing, and other repetitive physical demands. A structured ramp-in or work acclimation program allows employees to gradually build the strength, endurance, and tolerance needed to perform their jobs safely, reducing the risk of work-related musculoskeletal disorders (WMSDs).

What to Include

A successful work acclimation program should include:

• Gradual Workload Progression: Allow new employees to progressively increase their workload until they can safely sustain the physical demands of a full workday.
• Environmental Acclimation: Gradually expose employees to the environmental conditions associated with the job, such as temperature, pace, and work schedules.
• Job-Specific Ergonomic Training: Teach employees the safest and most ergonomic way to perform lifting, bending, reaching, squatting, climbing, and other essential job tasks while they acclimate.
• Ongoing Coaching: Reinforce proper body mechanics and safe work practices during the acclimation period to build long-term habits.

Why It Matters

Combining gradual work acclimation with job-specific ergonomic training helps employees safely adapt to the physical demands of their roles, significantly reducing the likelihood of a work-related musculoskeletal injury while improving confidence, productivity, and long-term workplace safety.

Action 3: Conduct Ergonomic Assessments and Implement Ergonomic Controls

What It Is

While the first two actions help build a stronger new workforce, existing employees also need protection from musculoskeletal disorders (MSDs). Ergonomic assessments identify workplace hazards that contribute to work-related musculoskeletal disorders (WMSDs) and provide the data needed to reduce employee exposure to injury risks through targeted ergonomic controls.

What to Include

A comprehensive ergonomics program should include:

• Ergonomic Assessments: Evaluate job tasks to identify and quantify ergonomic risk factors that contribute to musculoskeletal disorders.
• Hazard Prioritization: Assign ergonomic hazard scores to determine which job tasks present the highest risk and should be addressed first.
• Ergonomic Controls: Implement practical engineering, administrative, or work practice controls to reduce employees' exposure to identified hazards.
• Continuous Improvement: Conduct ongoing assessments and update ergonomic controls over time to systematically reduce workplace risk factors across all job roles.

Why It Matters

Most organizations cannot eliminate every ergonomic hazard at once. By identifying, measuring, and prioritizing the highest-risk tasks first, employers can make meaningful progress toward reducing work-related musculoskeletal disorders, improving workplace ergonomics, and creating a safer work environment over time.

Action 4: Provide Job-Specific Ergonomic Training

What It Is

Implementing ergonomic controls is only part of an effective musculoskeletal disorder (MSD) prevention strategy. Employees also need job-specific training on the safest and most ergonomic ways to perform their work. Proper lifting techniques, body positioning, breathing, muscle engagement, and the use of stretch breaks all influence fatigue levels, reduce strain on the body, and help prevent work-related musculoskeletal disorders (WMSDs).

What to Include

An effective ergonomic training program should include:

• Job-Specific Training: Teach employees the safest and most ergonomic techniques for performing the physical tasks required in their specific roles.
• Proper Body Mechanics: Train employees on correct lifting techniques, body positioning, breathing, and muscle engagement to reduce unnecessary strain on the musculoskeletal system.
• Stretch Breaks: Educate employees on when and how often to incorporate stretch breaks to manage fatigue during physically demanding work.
• On-the-Job Reinforcement: Reinforce classroom or online training through hands-on coaching at the job site, whether in the field, on the production floor, in the warehouse, or in other work environments.
• Ongoing Refreshers: Continue reinforcing body mechanics and ergonomic work practices over a period of 30–90 days, with periodic refresher training to build long-term safe work habits.

Why It Matters

Generic training alone rarely prevents musculoskeletal disorders. Job-specific instruction combined with ongoing reinforcement helps employees consistently apply safe work practices, reducing physical strain, lowering the risk of work-related musculoskeletal disorders, and creating lasting improvements in workplace safety.

Action 5: Implement an OSHA-Compliant Early Intervention Program

What It Is

Even with comprehensive musculoskeletal disorder (MSD) prevention strategies in place, work-related musculoskeletal disorders (WMSDs) can still occur, especially in jobs involving repetitive work, heavy physical demands, and awkward postures. When early symptoms appear, the best approach is to address them immediately through an OSHA-compliant Early Intervention Program (EIP) before they progress into more serious injuries.

What to Include

An effective Early Intervention Program should include:

• Employee Self-Reporting: Encourage employees to report discomfort or early symptoms of musculoskeletal pain as soon as they arise rather than waiting for them to worsen.
• Onsite First-Aid Treatment: Have a qualified EIP practitioner, typically an athletic trainer, physical therapist, or occupational therapist, provide OSHA-approved first-aid treatments for the musculoskeletal system, including heat or cold therapy, massage, and non-rigid supports such as sports taping.
• Ergonomic Work Practice Review: Evaluate the employee's work practices to ensure they are using the safest and most ergonomic techniques while performing their job.
• Flexible Care Options: For organizations without onsite treatment facilities, allow employees to receive early intervention services at a nearby clinic.
• Short-Term Intervention: Most employees require only 3–5 treatment sessions, experience significant improvement, and avoid the need for additional medical intervention.

Why It Matters

Many employees believe discomfort is simply part of physically demanding work. In reality, stiffness, fatigue, or mild pain often represent the earliest stages of a developing musculoskeletal disorder. Addressing musculoskeletal disorders at the first sign of discomfort can prevent minor symptoms from developing into recordable injuries, reduce lost work time, improve employee recovery, and help organizations lower the long-term costs associated with work-related musculoskeletal disorders.

Action 6: Implement Return-to-Work Testing and Work Conditioning

What It Is

Even when a comprehensive musculoskeletal disorder (MSD) prevention program is in place, some work-related musculoskeletal disorders (WMSDs) will still result in lost or restricted-duty workdays. When this happens, the next question is: When can the employee safely return to work? Too often, return-to-work decisions are made without objective information about the employee's physical ability to perform the essential demands of the job.

What to Include

An effective return-to-work program should include:

• Objective Return-to-Work Testing: Use a Return-to-Work Physical Abilities Test to evaluate whether the employee can safely perform the physical requirements of the job before returning to full duty.
• Job-Specific Assessments: Base return-to-work decisions on objective information that reflects the actual physical demands of the employee's role, rather than relying solely on medical recovery.
• Physician Support: Provide physicians with job-specific physical abilities test results so they can make informed return-to-work decisions.
• Work Conditioning: If an employee does not pass the return-to-work test, implement a short-term work conditioning program to restore the strength, endurance, and functional capacity needed to safely perform the job.

Why It Matters

Physicians typically release employees to return to work once they have reached maximum medical improvement, but medical recovery does not always mean an employee has regained full physical function. By using objective, job-specific testing and work conditioning when needed, organizations can make safer return-to-work decisions, reduce the risk of reinjury, and help employees return to work with greater confidence and long-term success.

Frequently Asked Questions

What is MSD, and is every musculoskeletal disorder work-related?

No. A musculoskeletal disorder (MSD) is any condition affecting the muscles, bones, joints, tendons, ligaments, nerves, or connective tissues. While some MSDs develop because of age, lifestyle, or medical conditions, others are directly related to workplace factors such as repetitive motions, heavy lifting, awkward postures, and poor ergonomics. These are known as work-related musculoskeletal disorders (WMSDs).

2. Can musculoskeletal disorders be prevented in physically demanding jobs?

Yes. While not every musculoskeletal disorder can be prevented, many work-related MSDs can be significantly reduced through job-specific Physical Abilities Testing (PAT), ergonomic assessments, workplace controls, employee training, early intervention, and safe return-to-work programs. A comprehensive prevention strategy is far more effective than relying on training alone.

3. Is ergonomic training alone enough to prevent musculoskeletal disorders?

No. Although ergonomic training is an important part of prevention, it is only one component of an effective musculoskeletal disorder prevention program. Organizations achieve better outcomes by combining ergonomic training with job analysis, Physical Abilities Testing (PAT), ergonomic assessments, early intervention, and return-to-work testing to address risks throughout the employee lifecycle.

4. Why is early intervention important for musculoskeletal disorders (MSDs)?

Early intervention helps address discomfort before it develops into a more serious musculoskeletal disorder or recordable workplace injury. Prompt evaluation, first-aid treatment, ergonomic coaching, and work practice adjustments can reduce recovery time, minimize lost workdays, lower workers' compensation costs, and help employees return to work safely.

5. Why isn't ergonomic training alone enough to prevent musculoskeletal disorders?

Ergonomic training helps employees perform physical tasks more safely, but it cannot eliminate workplace hazards by itself. Effective musculoskeletal disorder prevention also requires appropriate job design, ergonomic assessments, engineering controls, Physical Abilities Testing, early intervention, and objective return-to-work processes. Combining these strategies addresses risk throughout the employee lifecycle rather than relying on a single intervention.

Protect Your Workforce by Preventing Musculoskeletal Disorders Before They Happen

Organizations that achieve long-term reductions in musculoskeletal disorders rarely rely on a single initiative. Instead, they integrate hiring practices, workplace ergonomics, employee training, early intervention, and return-to-work strategies into a coordinated prevention system. Addressing risks at every stage of the employee lifecycle creates a stronger, healthier, and more resilient workforce while reducing long-term injury-related costs.

Key Takeaways

• Musculoskeletal disorders (MSDs) are one of the leading causes of workplace injuries, lost productivity, and workers' compensation claims.
• Preventing work-related musculoskeletal disorders (WMSDs) requires addressing both workplace hazards and personal risk factors.
