What Is a Trigger Point?
A trigger point is a sensitive area within a tight band of muscle that may produce local tenderness or pain felt in another area. Physical therapists assess these points through a patient history, movement checks, and gentle palpation. A trigger point can affect muscle comfort, flexibility, and the way a person performs everyday movements.

Key Takeaways About Trigger Point
- A trigger point sits within a tight band of muscle.
- Pressure and movement checks help identify its practical effects.
- A trigger point is not the same as a muscle spasm.
How Trigger Point Works
A trigger point forms in a taut section of muscle that does not relax normally. Pressure on the area may reproduce familiar discomfort, while movement may reveal restricted flexibility or a change in muscle control. Symptoms can stay near the sensitive spot or appear in a related region.

A physical therapist checks the area alongside posture, strength, joint motion, and the task that brings on symptoms. The assessment helps connect the tender spot with a movement pattern. Treatment may include guided exercise, hands-on techniques, stretching, or changes to daily activities. Referred pain describes discomfort felt away from the point that contributes to it. A muscle spasm involves a sudden, involuntary contraction and may occur with different findings.
From the Arrowhead Clinic Chiropractor Garden City team
When we assess a trigger point, we combine the person’s reported symptoms with movement testing and careful palpation. We also check whether the tender area changes strength, flexibility, or task performance. Our team uses those findings to guide Physical Therapy care and monitor functional changes.
Trigger Point in Practice: A Real-World Example
A person may report shoulder discomfort while reaching overhead. During Physical Therapy, the therapist may find a tender point in a nearby upper back muscle and observe limited shoulder movement. The assessment connects the local muscle finding with the movement complaint.
