Many experts believe that MLD techniques may be effective for releasing trigger points.
Manual lymph drainage (MLD) is a gentle manual treatment technique initially developed in the 1930’s by Danish Drs. Emil Vodder and Estrid Vodder. It is a type of gentle massage which is intended to encourage the natural drainage of the lymph, which carries waste products away from the tissues back toward the heart.
The Vodders began to study the lymph system in the early 1930's, developing light, rhythmic hand movements to promote lymph movement. They first introduced the technique 1936, in Paris, France, and after the second world war, they returned to Copenhagen to teach other practitioners to use this therapy.
Whilst scientific research has shown mixed results, MLD is practiced quite widely. A 2009 meta-analysis of studies in the area of sports medicine and rehabilitation showed the best evidence of effectiveness for Manual lymphatic drainage treatment to "enzyme serum levels associated with acute skeletal muscle cell damage as well as reduction of edema [swelling] around broken bones".
MLD is based on a "more subtle" approach
Manual Lymphatic Drainage (MLD) requires a more subtle approach and also a good knowledge of the morphology of the lymphatic system. Very light pressure is used to encourage lymph flow, as opposed to forcing blood through the system. MLD is considered by many therapists to be useful at releasing trigger points in the scalenes, anterior cervical musculature, and clavipectoral fascia (ex. in the acute phase of whiplash injury).
The Lymphatic System
Trigger Points and Lymphatic Flow
Trigger point activity has been demonstrated to attenuate lymphatic flow in the following ways (Simons et al. 1998):
- Scalene trigger points (especially anterior) cause tension that interferes with drainage into the thoracic duct. This is compounded by restrictions in the 1st rib mechanics (often secondary to trigger points in the middle and posterior scalenes).
- The peristaltic movement of lymph is disrupted by trigger points in the scalenes.
- Lymph flow in the arms and breast may be disrupted by trigger points in the subscapularis, teres major, and latissimus dorsi.
- Lymph flow to the breast may be further disrupted by trigger points in the anterior axillary fold (especially in the pectoralis minor). This commonly results from a protracted, chronically round-shouldered posture (Zinc 1981).
It is suggested that MLD should be employed either before deeper work or after it, in order to help remove excessive toxins and/or waste products from the tissues (Chaitow & DeLany 2000).
MLD procedure is best described (Harris & Piller, 2004) as follows:
Administer light, rhythmic, alternating pressure with each stroke.
Perform skin stretching and torque both longitudinally and diagonally.
Apply pressure and stretch in the direction of the desired fluid flow (not always in the direction of lymph flow).
Use light pressure over spongy, edematous areas and slightly firmer pressure over fibrotic tissue.
- Do not exceed a pressure of 32 mmHg.
