Summary

This study had the goal of analyse the neurophysiologic effects of both mechanical and manual cervical manipulation, in asymptomatic individuals.

Detailed description

In this study, the investigators compared the effects of manual manipulation and instrument assisted manipulation of C3/C4 on muscle tone, elasticity and stiffness and on pressure pain threshold , and pressure pain perception. The muscles evaluated were upper trapezius and biceps brachialis, bilaterally. The study also had a placebo and a control group. All individuals were asymptomatic.

Conditions

• Healthy Subjects

Interventions

Type	Name	Description
OTHER	Cervical spine manual manipulation	In the Manual manipulation group, the thrust was applied in the right side of C3/C4 with neutral flexion/extension, ipsilateral side bending and contralateral rotation. Then, a low amplitude, high velocity thrust in rotation was delivered.
OTHER	Cervical spine mechanical manipulation	In the Mechanical manipulation group, the Activator instrument was applied on the right transverse apophyses of C3.
OTHER	Placebo intervention	The subjects were positioned in the same pre-manipulative position as the manual manipulation group, but the thrust didn't occur. Instead, the position was hold for 3 seconds and then the subject's head returned passively to neutral position.
