RESUMO:
For several decades the evaluation of the electrical activity of respiratory muscles has
been used in clinical and physiological studies. On the other hand recently, new inspiratory
muscle training devices have been introduced in the commercially like electronic kinetic
valves. This thesis includes in its development a study of Health Technology Assessment,
systematic review and a clinical study. The aim of this thesis was to synthesize and
systematize a through systematic review methodologies used in the evaluation of surface
electromyography of extradiaphragm inspiratory muscles during the use of inspiratory
overloads and to evaluate the pattern of changes in thoracic wall volumes during use of
two forms of inspiratory muscle load: pressure-loading threshold (mechanical valve-MV)
versus resistive load to conical flow (electronic valve-EV) with loads (light, moderate and
high) in healthy individuals. A systematic review was conducted on the use of EMG for the
evaluation of extradiaphragm inspiratory muscles during the application of respiratory
muscle load, which was published in the Journal of Electromyography and Kinesiology.
The clinical study was performed 2 days where the use of the valves was randomized as
well as the loads with resistance that offered loads 30%; 50% and 70% of MIP. In both
valves the subjects breathed against the resistances for 3 minutes in each of the steps:
quiet breathing, loading and recovery. Among each load there was a rest period of 15
minutes. During the protocol, the evaluation of chest wall volumes through Optoelectronic
Plethysmography was performed concomitantly with evaluation of flow and pressure at the
mouth level. Fifteen volunteers were included in the study. An increase in chest wall
volumes was observed in the comparison between the loads with calm breathing and
recovery, but this increase was higher when using EV. The respiratory cycle was also
influenced during the use of both valves and in all loads with higher increments observed
during the use of the EV. In both valves the compartment that increased the most volume
was the pulmonary rib cage, but this increase was not statistically significant. The
application of inspiratory muscle load influences both the volumetric variables and the time
variables of the breath. The electronic valve tends to better optimize the effects on thoracic
wall volumes and make breathing more efficient.
