What Are Trigger Points?
Trigger points are hyperirritable spots in skeletal muscle—tight bands or knots that are painful when pressed and can cause referred pain (pain felt in a different area). They're common in chronic pain conditions and can contribute to headaches, neck pain, back pain, and other musculoskeletal problems.1
Characteristics of Trigger Points
- Tender spots in taut muscle bands
- Pain when compressed
- Referred pain patterns (pain elsewhere)
- Local twitch response when pressed
- Limited range of motion
- Muscle weakness without atrophy
Types2
Active Trigger Points
- Cause spontaneous pain
- Painful at rest
- Refer pain when pressed
Latent Trigger Points
- Only painful when pressed
- Can restrict movement
- May become active with stress
Common Locations
- Upper trapezius (neck/shoulder)
- Levator scapulae (neck)
- Quadratus lumborum (lower back)
- Piriformis (buttock)
- Gluteal muscles
- Temporalis (jaw/temple)
Treatment Approaches3
Manual Therapy
- Ischemic compression (sustained pressure)
- Myofascial release
- Massage therapy
- Stretching with spray and stretch
Needle Therapies
- Dry needling
- Trigger point injections
- Acupuncture
Other Treatments
- Ultrasound therapy
- TENS
- Laser therapy
- Heat application
Self-Treatment
- Foam rolling
- Tennis ball or lacrosse ball
- Massage tools (Theracane, etc.)
- Sustained pressure for 30-90 seconds
- Followed by stretching
What Causes Trigger Points
- Muscle overuse or injury
- Poor posture
- Repetitive movements
- Stress and tension
- Lack of movement
- Sleep problems
Prevention
- Regular stretching
- Good posture
- Stress management
- Ergonomic workspace
- Regular movement breaks
