Topic:
Appropriate duration for massage to increase peripheral blood flow and skin temperature of foot
Abstract:
Background: Massage is a popular technique to
increase peripheral blood flow. However, no
evidence that compared appropriate massage
duration for improving peripheral blood flow.
Objectives: To investigate the immediate effects of
massage at various time points on peripheral
blood flow and skin temperature of foot.
Methods: The study is a time series research
design. Thirty healthy volunteers aged 21.97±1.07
years received the Swedish massage at right
lower leg and foot for 40 minutes in controlledtemperature room at 24-26°c. Ankle systolic blood
pressure of Dorsalis pedis (aSBPd) and Posterior
tibial artery (aSBPp), ankle brachial index (ABI),
and skin temperature (T) of foot were measured
before massage and every 10 minutes. Data were
analyzed by one-way repeated measure ANOVA
and Bonferoni test, except aSBPd and aSBPp
were analyzed by Friedman test and Wilcoxon
signed rank test.
Results: The time effect of massage was
significantly detected on aSBPd (p = 0.001),
aSBPp (p = 0.024) and ABI (p=0.002,), but not on
a foot skin temperature. The aSBPd and aSBPp at
20, 30, and 40 minutes during massage
significantly increased when compared to before
massage while ABI significantly increased than
before massage just only at 20 and 30 minutes
during massage (P<0.01).
Conclusion: Massage (discontinuously or pause
every 10 minutes) for 20 minutes or more may
increase peripheral blood flow to the foot by
increase the blood pressure gradient.
