Trigger Point Therapy - Tension Type Headaches (TTH)

Posted by Simeon Niel Asher on

Headache Trigger Points

 


Tension headaches usually affect both sides of the head and last from thirty minutes to several days or more.

TTH are by far the most common type of chronic headache. People who experience migraines typically also have tension headaches in between their migraines these are also known as transformed headaches.

Symptoms of TTH

Tension headaches usually affect both sides of the head and last from thirty minutes to several days or more.

They often have a characteristic tight-band or vice like pain with a ‘dull steady aching’ quality. Symptoms can vary in intensity from mild to moderate to severe; they may also affect sleep.

These headaches are NOT accompanied by the additional symptoms that traditionally distinguish migraine headaches such as light sensitivity (photophobia), and flashes and patterns in the eyes (visual scotoma).

Tension headaches are said to affect about 1.4 billion people (20.8% of the population) and are more common in women than men (estimated at 23% to 18% respectively).

TTH and trigger points

Muscular problems and tension are commonly associated with TTH and trigger points within muscles may either be causative or may perpetuate TTH.

The most commonly affected muscles are Trapezius, Sternocleidomastoid, Temporalis, Masseter and Occipitofrontalis. There is also a strong association with postural issues such as the upper crossed pattern.

The pain processing part of the central nervous system is almost certainly involved in TTH as it shows up abnormal in scans.

Trigger points often add to the misery of headaches because they are associated with peripheral and central sensitization.

Long-term inputs from trigger points may lead to a vicious cycle that converts periodic headaches into chronic tension headaches.

In these cases even if the original initiating factor is eliminated, the trigger point-central sensitization cycle can perpetuate or even worsen.

Aggravating Factors

TTH's are often aggravated by stress, anxiety, depression, fatigue, noise, and glare, but they can also be associated with neck arthritis or neck disc problems.

Acute or Chronic

TTH headaches can be episodic or chronic. Episodic tension-type headaches are defined as tension-type headaches occurring fewer than 15 days a month, whereas chronic tension headaches occur 15 days or more a month for at least 6 months.

Headaches can last from minutes to days, months or even years, though a typical tension headache lasts 4–6 hours.

Seven Main Causes

The following are considered some of the main causes of TTH:

  • Sleep deprivation

  • Stress: usually occurs in the afternoon after long stressful work hours
  • Uncomfortable stressful position and/or bad posture

  • Irregular meal time (hunger is reported in up to 50% of people)

  • Eyestrain

  • Tooth Clenching (bruxism)

  • Postural issues

Treatment

Numerous studies have indicated that active trigger points in neck and shoulder muscles contribute to tension-type headache, and that the pain profile of this headache may be provoked by referred pain from active TrPs in the posterior cervical, head and shoulder muscles.

The presence of active trigger points has also been associated with a higher degree of sensitization in tension-type headaches. 

We treat headache sufferers daily in our clinics, and our own experience continues to confirm that trigger point therapy can have both immediate and long lasting effects for the treatment of tension type headaches and importantly can help to reduce dependency on medication.
