Effect of the diaphragmatic myofascial release technique on flowmetry results in healthy university students: pilot test

Abstract

Introduction: post-COVID motor and respiratory sequelae have become a public health problem for rehabilitation teams around the world. Diaphragmatic myofascial release may be a strategy to improve respiratory parameters measured with flowmetry. Objective: to determine the effect of diaphragmatic myofascial release on respiratory function measured with flowmetry in healthy university students.Method: quasi-experimental study of before and after design, 32 healthy subjects, divided into 15 men and 17 women, with an average age of 23,97 years, a basal flowmetry was performed, immediately diaphragmatic myofascial release was performed for 10 minutes in a supine position, and then, perform flowmetry after diaphragmatic release. Results: the flowmetry values pre and post diaphragmatic myofascial release showed different results, PEF (peak expiratory Flow) pre versus post, shows a statistically significant difference (p=0,04). Meanwhile, the FEV1 value (Forced expiratory volume in 1 second) showed a statistically non-significant difference (p=0,37).Conclusions: diaphragmatic myofascial release can be a manual strategy to improve lung capacity
