| Objective:To develop a new device combining central posteroanterior spinal mobilization with cervical traction,and to estimate the effect of traction forces on spinal mobilization.Methods:The device was designed as mechanical and electrical integration structure,including traction and mobilization systems.Thirty asymptomatic volunteers lied on the device with the indentor focused on the 5th cervical spinous process.Central mobilizations(10-30 N,1Hz)were applied with different traction forces (0,3,5,7kg).Realtime mobilization forces and displacements were recorded during treatment. Results:Mean realtime peak and minimum forces(SEM)were(27.52±0.58)N and(4.57±0.52)N respectively.Intraclass correlation coefficients(ICC) of forces were more than 0.99.The mean maximum displacements of indentor had no significant difference in various traction forces.Conclusion:The new device can provide consistent and safe central posteroanterior spinal mobilization in combination with traction. |
