Workplace injuries do not always result from a single accident. Repeated lifting, gripping, typing, or reaching can gradually cause pain, weakness, numbness, and difficulty moving.
South Carolina recognizes qualifying gradual injuries as repetitive trauma injuries. These claims require medical evidence connecting the condition to repetitive job duties, rather than simply showing that symptoms occur at work.
Morris Law, LLC helps employees pursue workers’ compensation benefits when repeated work activities cause injuries. Understanding the evidence requirements can help workers document how their condition develops.
What Is a Repetitive Trauma Injury?
Under S.C. Code § 42-1-172, a repetitive trauma injury develops gradually through the cumulative effects of repetitive traumatic events. Qualifying claims involve a series of similar activities performed regularly or frequently over an extended period.
For example, a ladder fall usually provides an identifiable injury event. Shoulder pain from repeatedly lifting materials overhead may instead develop over months.
Activities that may contribute to repetitive injuries include:
- Typing or data entry
- Repeated lifting and carrying
- Gripping tools or operating vibrating equipment
- Reaching overhead
- Frequent bending or twisting
- Performing repeated assembly-line movements
- Pushing or pulling heavy objects
Performing these activities does not automatically establish eligibility. Their frequency, duration, physical demands, and connection to the diagnosed injury all matter.
Why Do These Claims Require Different Evidence?
A sudden workplace injury may have witnesses and an incident report documenting a specific event. A repetitive injury often lacks that clear starting point.
Instead, the evidence must explain the pattern of work and how it relates to the condition. Useful details include the weight of materials handled, repetitions per shift, body position, and time spent performing each task.
Medical records, work schedules, job descriptions, and coworker accounts can help establish that history. These details support a claim for a work-related injury, but they do not replace the required medical evidence connecting the injury to employment.
Medical Evidence Must Connect the Injury to Work
A diagnosis identifies the condition, but it does not necessarily establish that repetitive job duties cause it. Under S.C. Code § 42-1-172, medical evidence must establish a direct causal relationship between the work conditions and the injury.
A workers’ compensation commissioner must find that connection by a preponderance of the evidence, meaning it is more likely than not. Qualifying evidence includes opinions, testimony, records, and documentation from licensed and qualified physicians.
For example, a carpal tunnel diagnosis alone may leave questions about its cause. The physician needs an accurate account of the worker’s gripping, wrist movements, equipment use, and time spent performing those tasks.
Providing those details helps support a repetitive injury claim with medical findings that reflect the actual demands of the job.
What Injuries Can Develop From Repetitive Work?
Repetitive work can affect different areas of the body, depending on the movements and physical demands involved. Conditions may include:
- Hand and wrist conditions: Carpal tunnel syndrome and tendon problems associated with repeated movements.
- Elbow and shoulder conditions: Injuries involving repetitive gripping, lifting, or overhead reaching.
- Knee, neck, and back conditions: Problems that may involve repeated bending, lifting, twisting, or other physical demands.
These conditions do not automatically qualify for benefits. The medical evidence must connect the diagnosed injury to the employee’s regular repetitive activities. Symptoms that worsen during work can inform the evaluation, but they do not replace that proof.
When Must a Repetitive Injury Be Reported?
Under S.C. Code § 42-15-20(C), employees generally have 90 days to notify their employer after discovering that the condition is compensable. The period also applies when reasonable diligence should lead to that discovery.
“Compensable” means qualifying for workers’ compensation under the applicable legal requirements. The clock does not necessarily start with the first episode of soreness, but workers should not assume a formal diagnosis always starts it.
Report a suspected work-related injury promptly and keep a dated copy of the notification. Records of symptoms, medical advice, and changes in job duties can help establish the timeline.
Limited relief for late notice may apply if the Commission accepts a reasonable excuse and finds no undue prejudice to the employer. Reporting the condition to an employer is also separate from formally filing a claim with the Commission.
What Is the Filing Deadline for Repetitive Trauma Claims?
Notifying your employer does not replace filing a claim with the South Carolina Workers’ Compensation Commission. Under S.C. Code § 42-15-40, repetitive trauma claims generally have two filing limits:
- Two years after you know or should know the injury qualifies for workers’ compensation.
- No more than seven years after the last date of injurious exposure, even without awareness that employment caused the injury.
The seven-year limit does not give every worker seven years to file. The two-year deadline may expire sooner.
Keep records showing when symptoms develop, when you seek treatment, and when medical advice identifies a possible work connection. Also document when the repetitive activity ends. These dates can help establish the timeline, but no single event automatically determines every claim’s deadline.
How Can Workers Document Repetitive Job Duties?
A job title rarely explains the physical demands of a shift. Detailed records give medical providers a clearer basis for assessing how repeated movements relate to an injury.
Useful documentation includes:
- Job descriptions and schedules: Tasks performed, shift lengths, overtime, and breaks.
- Production records: The pace and approximate number of repeated movements.
- Photographs or videos: Body positions, equipment, and task movements, where recording is permitted.
- Coworker accounts: Observations about duties and how frequently they occur.
- Assignment changes: New tasks, increased workloads, or changes in equipment.
- Medical records: Symptoms, findings, and the work history provided during treatment.
For example, “frequent lifting” provides less detail than describing the weight, repetitions per hour, lifting height, and years performing the task. Accurate information helps support a claim for workplace injury benefits without relying on assumptions about the occupation.
What If You Have a Preexisting Condition?
A prior injury or medical condition does not automatically prevent a repetitive trauma claim. However, medical evidence must still establish the required connection between repetitive work activities and the injury being claimed.
The evaluation may consider earlier symptoms, previous treatment, outside activities, and changes associated with job duties. Simply experiencing pain at work does not establish causation. Likewise, a medical history does not automatically rule out a qualifying work-related injury.
Give your physician a complete, accurate account of your condition and responsibilities. Explain what symptoms existed before the current problem and how they change over time.
What Benefits May Be Available?
A qualifying repetitive trauma injury may provide access to treatment and financial support under South Carolina’s Workers’ Compensation Act. Depending on the circumstances, benefits may include:
- Authorized medical care: Treatment, rehabilitation, and other medically necessary services related to the covered injury.
- Temporary disability payments: Partial wage replacement when qualifying work restrictions prevent you from working or reduce your earnings.
- Permanent disability benefits: Compensation for qualifying lasting impairment or disability after your condition reaches maximum medical improvement.
Eligibility depends on medical findings, work restrictions, earnings, and other legal requirements. Workers’ compensation generally does not pay damages for pain and suffering.
Disputes may concern the connection to work, recommended treatment, benefit calculations, or compliance with reporting and filing deadlines.
Keep Your Records Accurate as the Claim Develops
Your duties, symptoms, and treatment may change while the claim progresses. Update your medical provider about new assignments, increased workloads, or restrictions that affect your ability to work.
Review records for factual errors and request corrections when necessary. A note describing occasional lifting may give an incomplete picture if you perform that movement hundreds of times per shift. Accuracy matters more than making every account sound identical.
Getting Help With a Gradual Injury
An injury does not need a single accident date to qualify for workers’ compensation. Repetitive trauma claims depend on medical evidence, a detailed work history, and compliance with notice and filing requirements.
