简要总结
This study had the goal of analyse the neurophysiologic effects of both mechanical and manual cervical manipulation, in asymptomatic individuals.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Cervical spine manual manipulation (Other)
Mechanical manipulation
In the Mechanical manipulation group, the Activator instrument was applied on the right transverse apophyses of C3.
干预措施: Cervical spine mechanical manipulation (Other)
Placebo
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.
干预措施: Placebo intervention (Other)
Control
The subjects stayed in supine position and no intervention occurred.
结局指标
主要结局
Pressure pain thresholds
时间窗: Immediately after the intervention
To measure the pressure pain threshold, it was used an electronic pressure dynamometer FORCE ONE™ FDIX (Wagner Instruments - Greenwich, USA), with 1cm2 of surface. The values were expressed in Kg/cm2. The pressure was increased at a rate of 1 kg/cm2/s until the subject inform that the sense of pressure has become a sense of pain.
Pressure pain perception
时间窗: Immediately after the intervention
To evaluate the pressure pain perception, it was used a Visual Analogue Scale (VAS). The pressure increased until 2,5 kg/cm2 and was hold for 5 seconds, and the subject used the VAS scale to record the pressure pain perception he felt.
次要结局
- Muscle tone(Immediately after the intervention)
- Muscle stiffness(Immediately after the intervention)
- Muscle elasticity(Immediately after the intervention)
