Brief Summary:
There is evidence of the interdependence between the diaphragm and the C4 vertebral level with regard to nerve, fascial and muscular connections. The purpose of this study is to evaluate the influence of cervical bilateral manipulation (C3/C4) on the thoracoabdominal kinematics in healthy young adults.
Detailed Description:
Due to respiration the thoracoabdominal kinematics is considered a complex mechanism that evolves the movement of the ribs and fascia, the diaphragmatic function, the respiratory muscles and the mechanical properties of the airways that includes a coordinated reflex neural activity. The phrenic nerve (C3 to C5) is responsable for the motor and sensory innervation of the diaphragm.
The High Velocity Low Amplitude (HVLA) vertebral manipulation stimulates the corresponding spinal nerves. It is well known that when this manipulation is applied to cervical region induces vasomotor cutaneous and cardiorespiratory modifications in autonomic nervous system.
The sample composed of healthy young adults (aged 18-40 years) will be assigned randomly in three groups: experimental group (bilateral C3/C4 HVLA manipulation), sham manipulation group (passive cervical mobilization) and control group (no intervention). The thoracoabdominal kinematics measures will be assessed at baseline, right after the intervention and five minutes after the second measure using the Qualisys Motion Capture System.
