Objective:To reveal the force mechanism for therapeutic effect of pushing manipulation with one-finger meditation.Methods:A total of 15 participants were recruited in this study and assigned to an expert group,a skilled group and a novice group,with 5 participants in each group.Mechanical signals were collected from a biomechanical testing platform,and these data were further observed via similarity analysis and cluster analysis.Results:Comparing the force waveforms of manipulation revealed that the manipulation forces were similar between the expert group and the skilled group (P＞0.05).The mean value of vertical force was 9.8 N,and 95% CI rang from 6.37 to 14.70 N,but there were significant differences compared with the novice group (P＜0.05).The result of overall similarity coefficient cluster analysis showed that two kinds of manipulation forces curves were existed between the expert group and the skilled group.Conclusion:Pushing manipulation with one-finger meditation is a kind of light stimulation manipulation on the acupoint,and force characteristics of double waveforms continuously altemated during manual operation.
