What Is a Strain?
A strain is an injury to a muscle or tendon caused by overstretching or tearing tissue. Strains often develop during forceful movement, repeated activity, or a sudden change in load. Symptoms may include localized pain, tenderness, swelling, weakness, or reduced movement. The affected tissue and injury severity guide evaluation and treatment.

Key Takeaways About Strain
- Strains affect muscles or tendons, not ligaments.
- Pain and weakness may limit normal sports movements.
- A strain is commonly confused with a sprain.
How Strain Works
Strain develops when force places more demand on muscle or tendon tissue than the tissue can manage. The tissue may become irritated, overstretched, or partially torn. A strain can affect a small area or limit movement across a larger muscle group, depending on the affected structure.

Sports injury evaluation considers the activity, movement that caused symptoms, pain location, strength, and range of motion. A clinician may compare the involved side with the opposite side and check whether specific movements reproduce symptoms. Sprain describes a ligament injury, while strain describes muscle or tendon involvement.
From the Advanced Injury Care Clinic team
When we assess a strain during Sports Injury Treatment, we connect the reported activity with the exact movement that brings on symptoms. We check tenderness, strength, and range of motion while considering nearby joints and tissues. Our findings help shape care around the person’s sport and current activity level.
Strain in Practice: A Real-World Example
A recreational runner may develop a thigh strain after accelerating during a game. The person may notice localized pain and weakness when pushing off, climbing stairs, or repeating the same running motion.
