High-resolution manometry (HRM) before and after respiratory physiotherapy in a case of hypotensive lower esophageal sphincter (LES). The finding on HRM shows an increase in the tone of the LES after respiratory physiotherapy was applied in a patient with initial hypotensive LES. Left: Evaluation in the landmark (a) and in a swallow (b) before respiratory physiotherapy (mean LES pressure 7.9 mmHg). Right: Evaluation in the landmark (c) and in a swallow (d) after respiratory physiotherapy (mean LES pressure 33.3 mmHg)
