Populations and Risk Factors
- Individuals with a history of chronic asthma or atopic conditions
- Exposure to allergens (pollen, dust mites, pet dander), cold air, tobacco smoke, or pollution
- Emotional stress, exercise, respiratory infections, and GERD as triggers
- Sensitivity to aspirin or NSAIDs (aspirin-induced asthma triad with nasal polyps)
Causes and Pathophysiology
- Triggers initiate IgE-mediated mast cell degranulation releasing histamine, prostaglandins, and leukotrienes
- Three primary airway changes: smooth muscle spasm (bronchospasm), mucosal edema, and viscous mucus production
- Air can be inhaled but narrowed bronchioles make exhalation extremely difficult, trapping air in alveoli
- Lung hyperinflation results from chronic air trapping
Signs and Symptoms
- High-pitched expiratory wheezing. Persistent cough (dry or with thick, clear sputum)
- Dyspnea, chest tightness, and intercostal retractions
- Tachycardia, tachypnea, and use of accessory muscles
- Anxiety, panic, or "impending sense of doom"
- Cyanosis of lips or face (late, critical sign of severe hypoxia)
- "Silent chest" indicates no air movement and impending respiratory failure
Assessment
| Assessment Stage | Tests | Expected Findings | Rationale |
|---|---|---|---|
| History | Trigger audit | Recent allergen, smoke, or cold air exposure | Connects symptoms to environmental precursor |
| History | Medication review | Bronchodilator or corticosteroid use | Classifies asthma stage and stability |
| Visual Inspection | Posture scan | Barrel chest; tripod position | Chronic hyperinflation and breathing effort |
| Observation | Speech difficulty | Cannot speak in full sentences | Severity indicator of respiratory distress |
| Palpation (5 T's) | Accessory muscle tone | Hypertonicity in scalenes, intercostals, upper trapezius | Postural adaptations to difficult breathing |
| Functional | Peak flow meter (PEF) | Below 50% of personal best (Red Zone) | Objective measure of severe obstruction |
| Special (Med) | Spirometry | Low FEV1/FVC ratio (below 75-80%) | Gold standard for airflow limitation |
CMTO Exam Relevance
- Category: A7 Systemic Conditions (Respiratory)
- Red flags: Silent chest (no wheezing) indicates airways so obstructed no air moves — medical emergency. Cyanosis signals critical hypoxia. PEF below 50% is Red Zone requiring emergency response.
Massage Therapy Considerations
- Contraindications: Massage is strictly contraindicated during an active asthma attack
- Environment: Session room must be free of scents, essential oils, and candles. Use hypoallergenic lubricants
- Positioning: Semi-supine, side-lying, or seated positions preferred due to orthopnea
- Techniques: Between episodes, focus on muscles of respiration (diaphragm, intercostals, scalenes) to reduce chronic tension
- Caution: Avoid tapotement on the back as it can trigger coughing or bronchospasm
- Emergency: If a client struggles during session, assist to seated position, encourage diaphragmatic breathing, and ensure access to their emergency inhaler
Key Takeaways
- Massage is strictly contraindicated during an active asthma attack. A "silent chest" (no wheezing) indicates a life-threatening emergency.
- The treatment room must be free of scents, essential oils, and candles. Use only hypoallergenic lubricants.
- Position clients semi-supine, side-lying, or seated due to orthopnea. Avoid tapotement on the back as it can trigger bronchospasm.
- Between episodes, focus on muscles of respiration (diaphragm, intercostals, scalenes) to reduce chronic tension.
- If a client struggles during a session, assist to seated position, encourage diaphragmatic breathing, and ensure access to their emergency inhaler.
