Manual Cervical Traction and Trunk Stabilization Cause Significant Changes in Upper and Lower Esophageal Sphincter
Significant Changes in Upper and Lower Esophageal Sphincter
Abstract
Objectives: Dysfunctions in the lower esophageal sphincter (LES) and the upper esophageal sphincter (UES) levels can occur owing to poor muscle coordination, contraction, or relaxation. Such condition can possibly be addressed by functional rehabilitation. The aim of this study was to measure pressure changes in the upper esophageal sphincter (UES) and lower esophageal sphincter (LES) at rest and during routine rehabilitation techniques, that is, cervical manual traction and trunk stabilization maneuver.
Results: Average initial resting upper esophageal sphincter (UES) pressure was 90.91 mmHg. A significant decrease was identified during both cervical traction (average UES pressure = 42.13 mmHg, P < .001) and trunk stabilization maneuver (average UES pressure = 62.74 mmHg, P = .002). The average initial resting lower esophageal sphincter (LES) pressure was 14.31 mmHg. A significant increase in lower esophageal sphincter (LES) pressure was identified both during cervical traction (average LES pressure = 21.39 mmHg, P < .001) and during the trunk stabilization maneuver, (average pressure = 24.09 mmHg, P < .001).
Conclusion: Cervical traction and trunk stabilization maneuvers can be used to decrease pressure in the upper esophageal sphincter (UES) and increase lower esophageal sphincter (LES) pressure in patients with gastroesophageal reflux disease.
