Can myofascial techniques modify immunological parameters?

The objective was to determine the effect of myofascial techniques on the modulation of immunological variables.

Thirty-nine healthy male volunteers were randomly assigned to an experimental or control group.

The experimental group underwent three manual therapy modalities: suboccipital muscle release, so-called fourth intracranial ventricle compression, and deep cervical fascia release. The control group remained in a resting position for the same time period under the same environmental conditions.

Changes in counts of CD3, CD4, CD8, CD19, and natural killer (NK) cells (as immunological markers) between baseline and 20 minutes post-intervention.

Repeated-measures ANOVA revealed a significant time × groups interaction (F(1,35)=9.33; p=0.004) for CD19. There were no significant time × group interaction effects on CD3, CD4, CD8, or NK cell counts. Intrasubject analyses showed a higher CD19 count in the experimental group post-intervention versus baseline (t=-4.02; p=0.001), with no changes in the control group (t=0.526; p=0.608).

A major immunological modulation, with an increased B lymphocyte count, was observed at 20 minutes after the application of craniocervical myofascial induction techniques.
