Positional Therapy May Ease COPD Breathlessness, suggests research
Researchers have found in a new study that Positional therapy may help reduce dyspnoea in patients with COPD. Incorporating beneficial postures into pulmonary rehabilitation or using them at night could improve symptoms and quality of life.
Patients with advanced COPD often report that adopting a specific body posture improves their dyspnoea. Exploring the underlying mechanisms could enhance our understanding of the origin of this symptom and approaches towards its alleviation. Pulmonary function tests and detailed sensory–mechanical measurements, including gastro-oesophageal catheter-based crural diaphragm electromyography (surrogate for inspiratory neural drive (IND)) and respiratory manometry, were performed in 16 patients (nine males; mean±sd age 66±7 years) with advanced COPD (mean±sd forced expiratory volume in 1 s 36±16% predicted and residual volume/total lung capacity 55±11%) while adopting their most favourable (MF) and least favourable (LF) postures.
The MF postures included sitting upright (56%), sitting with arms on knees in a forward-leaning position (25%), standing (13%) and lying with three pillows (6%). About two-thirds of patients choose the supine posture as the LF posture. There were no significant differences in minute ventilation and inspiratory capacity between MF and LF postures (p>0.05). Compared to LF postures, MF postures were associated with 1) increased dynamic lung compliance, 2) lower transdiaphragmatic pressures and 3) reduced total work of breathing, leading to 4) decreased IND to the diaphragm and 5) improved neuromechanical and neuroventilatory coupling (all p<0.05). The decrease in the “difficulty breathing in” dyspnoea qualifier when assuming the MF posture correlated with corresponding improvements in neuromechanical dissociation (r=0.62, p=0.01) and neuroventilatory dissociation (r=0.57, p=0.02).
Healthcare professionals should evaluate the benefits of positional therapy for reducing dyspnoea in patients with COPD. Incorporating postural interventions into rehabilitation or using them at night may help lessen symptoms and improve quality of life.
