Objective:To explore the biomechanical characteristics of one-finger zen push method when applied to the cervical region.Methods:Ten senior tuina physicians were recruited to perform the one-finger zen push method on bilateral cervical muscles under three force conditions:light,moderate,and heavy.A dynamic pressure distribution system was employed to capture key biomechanical parameters,with each force condition maintained for 3 minutes.Data from the middle 1-minute segment were analyzed,focusing on maximum force,mean force,peak pressure,mean pressure,force-time integral(FTI),pressure-time integral(PTI),and frequency.Results:Under light,moderate,and heavy manipulation intensities,all biomechanical parameters,including maximum force,mean force,peak pressure,mean pressure,FTI,and PTI,demonstrated a progressive increasing trend with rising intensity levels when a senior Tuina practitioner performed the moving one-finger zen manipulation on the cervical region.Overall,mechanical outputs at the heavy intensity level were consistently higher than those at the moderate and light levels,and the moderate level was higher than the light level,indicating a clear graded differentiation across the three predefined intensities.In contrast,operational frequency showed only minor variation among the three intensity conditions and did not exhibit a corresponding increase with greater manipulation intensity.Conclusion:This study quantitatively characterizes the biomechanical parameters of the one-finger zen push method applied to the cervical region under different force conditions,providing empirical data for the scientific transmission of tuina techniques.The findings offer an objective reference for ensuring the safety and efficacy of clinical manual therapy.
