What Is Strain?
A strain is an injury to a muscle or tendon caused by overstretching or forceful loading. The injury may involve irritation, small tissue damage, or a partial tear. Strains often affect the back, neck, shoulder, or limb after lifting, reaching, twisting, repetitive work, or a sudden movement. Symptoms can include pain, tenderness, weakness, and reduced movement.

Key Takeaways About Strain
- Strain affects muscle or tendon tissue.
- Work tasks can stress tissue through force or repetition.
- A strain is not the same as a ligament sprain.
How Strain Works
A strain develops when muscle or tendon tissue handles more force or stretch than it can tolerate. The tissue may become irritated or sustain a partial tear, which can affect strength and movement. Repeated lifting, awkward reaching, sudden loading, and prolonged physical tasks can all place stress on the same area.

Clinical assessment connects the reported work activity with findings such as tenderness, weakness, and changes in Range of Motion. The location and pattern of symptoms help distinguish a strain from problems involving a joint, nerve, or ligament. A Sprain involves a ligament, while a strain involves muscle or tendon tissue.
From the Arrowhead Clinic - Lithia Springs team
When we assess a strain, we review how the work activity began, where symptoms occur, and which movements change them. We also check movement, strength, tenderness, and nearby structures so the treatment record reflects the reported workplace injury.
Strain in Practice: A Real-World Example
A warehouse employee lifts a loaded box and feels pain develop across the lower back. The work-related strain may produce tenderness, guarded movement, and difficulty with bending during the examination.
