What Is a Muscle Strain?
A muscle strain is an injury to a muscle or the tendon connecting it to bone, caused when tissue is stretched beyond its normal capacity or forced to contract under load. The injury may affect a small group of fibers or a broader area, producing localized pain, tenderness, weakness, or reduced movement.

Key Takeaways About Muscle Strain
- Strains affect muscles or the tendons attached to them.
- Pain may increase during movement or muscle contraction.
- A strain is not the same as a ligament sprain.
How Muscle Strain Works
A muscle strain develops when force places more stress on muscle tissue or its tendon than the tissue can manage. The affected area may become painful, tender, weak, or less able to move normally. Symptoms can appear during the activity or soon afterward, depending on how the tissue was loaded.

Assessment connects the reported activity with the location and behavior of symptoms. A clinician may review how the injury occurred and observe movement, muscle use, and Range Of Motion. Palpation can help identify tender tissue. This process also helps distinguish a strain from conditions such as a Ligament Sprain, which affects a different type of connective tissue.
From the Arrowhead Clinic Chiropractor Marietta team
When we assess a muscle strain, we review the work activity, symptom location, and movements that reproduce discomfort. We also check nearby joint motion and muscle function to understand how the injury affects daily tasks. Our team records these findings as part of a work injury evaluation.
