What Is a Strain?
A strain is an injury to a muscle or tendon caused by overstretching or excessive force. The injury may affect muscle fibers, the tendon that attaches muscle to bone, or both. Symptoms can include localized pain, tenderness, weakness, swelling, or limited movement, depending on the tissue involved and the work activity.

- A strain is commonly confused with a sprain.
How Strain Works
Strain describes damage that develops when muscle or tendon tissue is stretched or loaded beyond its current tolerance. The tissue may become irritated, partially damaged, or less able to produce normal force. Pain often appears near the affected area, and movement may feel restricted or weak.

A work-related strain can follow lifting, pulling, reaching, repetitive motion, or a sudden effort. Clinicians assess the location of symptoms, tenderness, movement, strength, and the activity that preceded the problem. Muscle Spasm may occur with a strain, while Sprain refers to an injury involving a ligament around a joint. These terms help describe different tissues involved in a work injury.
From the Arrowhead Clinic Chiropractor Newnan team
When we assess a work-related strain, we review how the injury happened and which movements reproduce symptoms. We check movement, strength, tenderness, and nearby joints to understand how the affected area functions during the job. Our findings help guide a clear treatment record.
