Anxiety disorders are among the most prevalent mental health conditions worldwide and represent a significant public health concern, particularly among young adults and university students, who frequently experience academic, social, and financial stressors. The aim of this randomized clinical trial is to evaluate the effect of a protocol, consisting of 4 manual techniques, compared to a placebo group, in heart rate variability immediately after the intervention and in anxiety after one week in young adults. The main questions it aims to answer are:\n\nDoes the osteopathic intervention protocol influence the parasympathetic nervous system? Does the osteopathic intervention protocol influence anxiety and stress?\n\nThe researchers will compare the osteopathic protocol to a placebo (simulation technique), in order to see if the protocol influences anxiety and stress. Participants will:\n\nPrior to the intervention, complete the EADS questionnaire and undergo measurement of heart rate variability; Undergo the protocol or placebo; Immediately after the intervention, they will undergo the measurement of heart rate variability; After one week in the intervention, complete the questionnaire EADS.",[91,92],"Stress","Anxiety",[92,94,95,96,97,98],"Autonomic System Nervous","Parasympathetic Autonomic System Nervous","heart rate variability","Manual Therapy Techniques","Young Adults","NOT_YET_RECRUITING","2026-06-25",{"date":102,"type":103},"2026-06-29","ACTUAL",{"date":105,"type":85},"2026-06",{"date":107,"type":85},"2026-09",{"name":5,"class":6},1]
