Objective
To investigate whether the decrease in dyspnea in neuromuscular diseases after air stacking (AS) occurs mostly in patients with decreased inspiratory muscle force and ensuing chest wall restriction or heterogeneous ventilation across the lungs. Design Interventional, before-after study. Setting A neurorehabilitation inpatient and outpatient center. Participants Fifteen consecutive adult patients affected by neuromuscular diseases (N=15). Interventions AS treatment. Main Outcome Measures Patients had vital capacity (VC) and sniff nasal inspiratory pressure (SNIP) measured. We measured Borg score, oxygen saturation, and ventilation heterogeneity across the lung as estimated from the difference between respiratory resistance at 5 and 19 Hz (R5-19) with the forced oscillation technique before and 5, 30, 60, and 120 minutes after applying AS. Results Before AS, Borg score was significantly related to R5-19 (r2 0.46, P<.05 but not to vc predicted snip and time since symptom onset. after as average borg score gradually decreased whereas inspiratory flow resistance at hz r5-19 reactance tended improve despite reaching statistical significance. the decrease in dyspnea minutes significantly correlated with baseline p r2 respectively onset clinical severity for patients affected by amyotrophic lateral sclerosis.> Conclusions These findings suggest that dyspnea in neuromuscular diseases is related to heterogeneous ventilation rather than inspiratory muscle force and/or lung volumes decrease. Restoring ventilation distribution across the lungs with AS appears to improve dyspnea. |
