Cumulative injuries typically arise over time rather than from a single occurrence, which makes them more difficult and expensive to treat. In fact, injuries of this nature are some of the most costly and complex workers’ compensation claims an organization will deal with. 

What’s more, cumulative injuries can often be long and painful experiences for employees. That’s why it’s important for your organization to mitigate the risk of these injuries — and minimize their impact should they occur.

What Are Cumulative Injuries?

Cumulative injuries — also known as repetitive movement or overuse injuries — usually stem from employees performing repeated movements while working within their job tasks over a period of time. These repetitive job tasks can lead to degeneration of the employees’ impacted body parts, eventually becoming symptomatic and needing treatment. 

Cumulative injuries can present in several different ways. Symptoms can include inflammation, numbness or tingling of extremities, swelling of joints and decreased range of motion. Common diagnoses for cumulative injuries are carpal tunnel syndrome and bursitis.

The following employees are more prone to cumulative injuries:

• Office workers who engage in frequent typing
• Factory line workers who pick or stand over a conveyor belt for hours daily
• Operators who use their hands to operate equipment
• Material handlers who perform lifting, carrying, pushing and pulling tasks frequently

Each of these occupations requires employees to perform the same job tasks repeatedly. That being said, cumulative injuries are a result of wear and tear on the body, so they tend to show up more in older workers who have been doing the same tasks for years. However, cumulative injuries can also show up in workers who practice poor posture and have inadequate ergonomics. In any case, the exact sources of these injuries are typically hard to determine.

Workers’ Compensation Claims From Cumulative Injuries

Since cumulative injuries often occur over an extended length of time, it can be challenging to discover their root causes. If an employee has been working within your organization for several years and has had several job tasks, it may be difficult to pinpoint the exact task that caused the injury. 

Employees may have symptoms that began several months back or even a year or more ago. The employee may not mention the pain, as they think it’ll go away on its own. It’s normally after the employee has dealt with the injury for a long time or when symptoms start to worsen that they finally report the injury. If it had been treated when the symptoms began, their injury could have been easier and less invasive to address.

Some employees start noticing symptoms shortly after starting a new position. In this scenario, there is a question of whether the employee has a preexisting injury, degeneration from previous work or other activities. Others experience soreness when getting used to moving their body in new ways or becoming accustomed to more manual labor. If it’s an exacerbation from a preexisting injury — but the symptoms flared up at work and the employee was performing job tasks that could have contributed to their symptoms — the employer could be held responsible for the resulting workers’ compensation claim unless the injury source is proven otherwise.

How to Mitigate Cumulative Injury Claims

Your organization must try to eliminate or reduce the repetitiveness of any job tasks that could potentially cause cumulative injuries. Be sure to perform ergonomic risk assessments on all job tasks to determine which hazards are present and provide solutions to those hazards. Solutions might include:

• Providing tools to make employees’ job tasks easier 
• Offering additional training in ergonomics to reduce incidents of sprains or strains
• Monitoring employees’ work practices to make sure they are using the correct tools and working within their physical limitations
• Creating a wellness program that boosts employees’ awareness on how to take care of their bodies
• Educating employees on proper reporting of injuries 
• Changing how job tasks are completed
• Utilizing mechanical operations rather than employees for certain job tasks (if applicable and logical to do so)

These assessments should be completed proactively to prevent any issues from arising from a process and then, after an injury occurs, to determine what movements or processes could have caused the injury. 

Cumulative Injury Treatment

Cumulative injuries often take a longer time to heal, leading to elevated treatment costs. Treatment options for cumulative injuries can include:

• Resting the injured extremity 
• Icing the affected area 
• Using contrast bath therapy 
• Receiving physical therapy 
• Getting surgery (in extreme cases) 

Cumulative injuries can result in time off from work, especially if an employee’s current job task aggravates their symptoms. In addition, if the employee discovers during treatment that they will be unable to return to their current job tasks, they may be provided vocational rehabilitation benefits through the employer’s workers’ compensation insurance. This benefit will help them find a new position or provide them with training for a new role altogether.
