Bilateral Cervical Manipulation (C3/C4) on Thoracoabdominal Kinematics

April 1, 2024 updated by: Natália Maria Oliveira Campelo, Escola Superior de Tecnologia da Saúde do Porto

Influence of Bilateral Cervical Manipulation (C3/C4) on Thoracoabdominal Kinematics on Healthy Young Adults: Randomized Controlled Trial (RCT)

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: HVLA manipulation

In the intervention of the experimental group, the investigator will be primarily on the right side of the volunteer and identify C3 through the cervical reference of jaw angle, which is at the disc level between C2/C3 and then contact with the phalanges of third metacarpal in the left transverse of this vertebra.

The volunteer will be seated with 110º of hip and knee flexion using a digital goniometer and will be asked to breath normally.

The investigator will apply an anterior and lateral translation associated with extension, homolateral inclination and contralateral rotation of the cervical. This procedure will increase the tension of the soft tissues to reduce the remaining slack and, finally, the thrust will be applied in pure rotation. Subsequently the head of the volunteer will be repositioned in the neutral position without applying any pressure and will wait 10 seconds in this position. Finally, the previous procedure will be repeated to the opposite side.
Sham Comparator: Sham technique

The investigator will be primarily on the right side of the volunteer and identify the C3 vertebra, having as anatomical reference the angle of the jaw, which is at the disc level between C2/C3 and then contact, with the phalanges of the third metacarpal, the left transverse apophysis of this vertebra.

The volunteer will be seated with 110º of hip and knee flexion using a digital goniometer and will be asked to breath normally.

The investigator will apply an anterior and lateral translation associated with extension, homolateral inclination and contralateral rotation of the cervical until the perception of tissue tension at the point of contact, holding this position for 10 seconds. The investigator then repositions the head of the volunteer in the neutral position without applying pressure, holding again this position for 10 seconds. Finally, the previous procedure will be repeated for the opposite side.
No Intervention: No intervention group
The volunteer will be seated with 110º of hip and knee flexion using a digital goniometer and will be asked to breath normally.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from Baseline in anterior-to-posterior of the abdomen right after the intervention
Time Frame: Immediately after the intervention

The Qualysis Motion Capture System will measure the variation of the tridimensional movement of the abdomen through the positioning of two reflectors that will be placed in standardized points: in the umbilicus and the spinal process of L3. The volunteer will be seated with 110º of hip and knee flexion using a digital goniometer and will be asked to breath normally for 90 seconds.

This measure instrument have eight infrared cameras which after the calibration process will determine the data of the tridimensional thoracoabdominal amplitude variations of the volunteer by the kinematic of the reflex markers.

Immediately after the intervention
Change from Baseline in anterior-to-posterior of the abdomen 5 minutes after the intervention
Time Frame: 5 minutes after the intervention
