Effect of Massage on Serum Level of -Endorphin and
β-Lipotropin in Healthy Adults
JANE A. DAY,

SARAH E. CHESROWN
We conducted this study to evaluate the effect of massage on the levels of
endogenous opiates in peripheral venous blood. The results were based on
findings from 21 healthy, adult volunteers. After separation by sex, the volunteers
were assigned randomly to either the Control Group (n = 11) that rested but
received no massage or the Experimental Group (n = 10) that received a 30-
minute complete back massage. We found no significant pretreatment or posttreatment
difference in blood
β-endorphin or β-lipotropin levels between the
groups. The results indicate that massage did not change significantly the
measured serum levels of β-endorphin or β-lipotropin in our healthy subjects
without pain. A follow-up study using patients experiencing acute or chronic back
pain is recommended. Massage is used routinely in the treatment of such patients,
and endogenous opiates are recognized as a possible mechanism for pain relief.

Increase of plasma beta-endorphins in connective tissue massage.

Abstract
1. Connective tissue massage produces relief of pain and increases microcirculation in a number of vascular beds. 2. The concentration of plasma beta-endorphins has been measured in 12 volunteers before and 5, 30 and 90 min after a 30-min session of connective tissue massage. 3. There was a moderate mean increase of 16% in beta-endorphin levels from 20.0 to 23.2 pg/0.1 ml (P = 0.025), lasting for about 1 hr with a maximum in the test 5 min after termination of the massage. 4. It is assumed that the release of beta-endorphins is linked with the pain relief and feeling of warmth and well-being associated with the treatment.

Abstract
Beta-endorphin (betaE) is an important reliever of pain. Various stressors and certain modalities of physiotherapy are potent inducers of the release of endogenous betaE to the blood stream. Most forms of exercise also increase blood betaE level, especially when exercise intensity involves reaching the anaerobic threshold and is associated with the elevation of serum lactate level. Age, gender, and mental activity during exercise also may influence betaE levels. Publications on the potential stimulating effect of manual therapy and massage on betaE release are controversial. Sauna, mud bath, and thermal water increase betaE levels through conveying heat to the tissues. The majority of the techniques for electrical stimulation have a similar effect, which is exerted both centrally and--to a lesser extent--peripherally. However, the parameters of electrotherapy have not yet been standardised. The efficacy of analgesia and the improvement of general well-being do not necessarily correlate with betaE level. Although in addition to blood, increased brain and cerebrospinal fluid betaE levels are also associated with pain, the majority of studies have concerned blood betaE levels. In general, various modalities of physical therapy might influence endorphin levels in the serum or in the cerebrospinal fluid--this is usually manifested by elevation with potential mitigation of pain. However, a causal relationship between the elevation of blood, cerebrospinal fluid or brain betaE levels and the onset of the analgesic action cannot be demonstrated with certainty.
