Healthy Situation Clinical Trial
Official title:
The Effect of Deep Friction Massage on the Achilles Tendon Blood Flow
Background: There is a hypothesis in literature that the mechanical action of deep
transverse friction massage (DTF) produces vasodilatation and increases blood flow. But as
yet, no experimental study has confirmed the effect of DTF on blood flow in the Achilles
tendon. Objective: The purpose of the present study was to investigate whether one session
of DTF can influence the Achilles tendon blood flow.
Design: a randomized pre- posttest trial was set up. Patients: Sixty-two healthy
participants volunteered. Each person underwent the following four steps of the procedure:
1. Measuring the tendon blood flow (PRE), 2.fifteen minutes of DTF on the Achilles tendon,
3. Measuring of the tendon blood flow (POST), 4.follow - up measurement after 20 minutes of
rest (POST20).
Intervention: one leg of each person was randomly assigned to deep transverse friction
session, the other leg was used as a control leg. Friction was applied continuously for a
total of 15 minutes. Measurements: the microcirculation was determined at 2 and 8 tissue
depths at the distal and the proximal midportion of the Achilles tendon. For each level, the
capillary blood flow, the tissue oxygen saturation, and the postcapillary venous filling
pressure was registered.
