The Diaphragm and Breathing - Trigger Point Therapy
How To Assess and Influence Your Breathing
Abnormal breathing mechanics may be one of the key factors in the development of chronic myofascial trigger points throughout the body
Trigger point therapy can be a useful tool in releasing the musculoskeletal component of respiratory dysfunction and is especially useful when combined with other modalities, such as yoga, Feldenkrais, meditation, the Buteyko method and “breath therapy.”
Nothing in the body happens in isolation, and an exploration of breathing mechanics exemplifies this.
Breathing involves many sequences of coordinated muscular and visceral co-contractions.
Trigger points can often be palpated along the anterior inferior costochondral margin.
These trigger points should be contextualized with other relationships such as:
Submandibular inferior margin (often on the opposite side to the diaphragm trigger points)
Abdominal visceral fascia (greater and lesser omenta)
Spinal muscles (especially mid lumbar)
Abdominal muscles (especially transversus and rectus abdominus)
Pelvic floor muscles (pelvic diaphragm)
Thoracic spine and rib mobility
1st rib mechanics
Scalenes, levator scapulae, and upper trapezius
Breathing patterns are often abnormal. Hyperventilation syndrome, panic attacks, and postural habit are increasingly diagnosed.
If untreated, these syndromes also have ongoing physiological consequences, such as respiratory alkalosis (too much carbon dioxide is exhaled by over-breathing).
Paradoxically, this situation is one of the key factors in the development of chronic myofascial trigger points throughout the body.
It may be interesting to note here that cranial osteopaths talk about eight diaphragms which all coordinate together in breathing: the diaphragma sellae, under the pituitary gland; the submandibular myofascial raphe, bilaterally; the thoracic inlet/outlet, bilaterally; the abdominal diaphragm; and the pelvic floor, bilaterally.
Abnormal breathing and trigger point formation
Garland (1994) suggested a sequence of musculoskeletal changes that may develop over time as a result of chronic upper chest respiration:
- Restriction in thoracic spine mobility (secondary to aberrant rib mechanics)
- Trigger point formation in scalenes group, upper trapezius, and levator scapulae
- Tight and stiff cervical spine
- Changes in tone of abdominal diaphragm and transversus abdominis (Hodges et al. 2001; McGill et al. 1995)
- Imbalance between weakened abdominal muscles and hypertonic erector spinae
- Pelvic floor weakness
