Manual Lymphatic Drainage

This page as PDF · Summary

1. What Manual Lymphatic Drainage Is

Manual lymphatic drainage is a manual technique within the treatment complex of decongestive therapy. It is described as a sequence of slow, rhythmic, low-pressure hand movements along the lymphatic pathways. In practice, it rarely stands alone: it is combined with compression, skin care and movement exercises, and this combination is also tested in the controlled studies. The investigated fields of application range from oncology through skin and the musculoskeletal system to fatigue and cognition. A separate area concerns safety and contraindications, including an international consensus paper on risks and contraindications of medical compression therapy. The technique is most frequently studied in lymphoedema of the arms after breast-cancer surgery.

The decisive point for the evaluation of all papers: manual lymphatic drainage is almost never tested in isolation. In most controlled studies it is added to compression, an exercise programme or standard therapy; several titles address precisely this adjunct question. Consequently, no effect of the hand technique alone can be inferred from such combination studies. In addition, the papers measure very different endpoints: the incidence of lymphoedema, shoulder function, quality of life, pain or the extent of swelling. These levels are not interchangeable. A swelling value is a marker, not a disease course. Anyone comparing studies must therefore first check whether the comparison group received another treatment, a sham treatment or no treatment.

The key human studies and the most important reviews — by field of application, with population, duration, preparation, measure and result as reported in the original papers. Numbers appear only where the work states them.

Distribution of controlled human studies by field of application — the numbers are not additive, as one paper may be assigned to several fields:

Oncology

Two randomised studies address prevention after breast-cancer surgery with axillary lymph-node dissection. In the 2010 study, 120 women in Alcalá de Henares received either manual lymphatic drainage, scar massage and progressive shoulder exercises plus education or education alone. Of 116 women with one-year follow-up, 18 developed secondary lymphoedema (16 %): 14 in the control group (25 %), four in the intervention group (7 %); the difference was significant (P=0.01), the risk ratio was 0.28 (95 % CI 0.10 to 0.79), and in the survival analysis lymphoedema occurred four times earlier in the control group 18. The second study included 160 women in Leuven and compared guidelines, exercise therapy and manual lymphatic drainage (n=79) with the same programme without manual lymphatic drainage (n=81) for six months; after twelve months the cumulative incidence was 24 % versus 19 % (odds ratio 1.3) 30. The two prevention studies yield differing results.

Three review articles summarise the randomised studies. The 2013 meta-analysis evaluated ten RCTs with 566 patients: two prevention studies found no significant difference in incidence (risk ratio 0.63; 95 % CI 0.14 to 2.82), and seven studies on arm-volume reduction likewise found none (weighted mean difference 75.12; 95 % CI −9.34 to 159.58) 1. The 2020 meta-analysis included 17 RCTs with 1911 patients; in the pooled analysis of eight RCTs with 338 patients, manual lymphatic drainage did not significantly reduce lymphoedema (standardised mean difference −0.09; 95 % CI −0.85 to 0.67), and the subgroup analyses by region, year of publication, sample size, type of surgery, statistical method, mean age and intervention duration largely agreed with the main result 2. The 2021 review covered 17 studies with 867 women and two men and reports contradictory findings: partly positive effects on volume, quality of life and symptoms, partly no additional benefit within complex decongestive therapy 11. Proven: Taken together, several meta-analyses show that manual lymphatic drainage as an adjunct to complex decongestive therapy does not demonstrate consistent additional benefit.

For treatment, a randomised study at six centres examined 103 women with at least 10% arm volume difference, of whom 95 were evaluable. The control group wore compression stockings, the experimental group received daily Manual Lymphatic Drainage and bandaging, followed by compression stockings. The proportion with at least 50% volume loss did not differ, nor did quality of life (SF-36) and arm function 19. Another randomised study in 41 patients with axillary web syndrome compared exercise therapy (three times weekly, four weeks; n=20) with exercise therapy plus Manual Lymphatic Drainage (five times weekly, four weeks; n=21); pain and arm volume were significantly lower in the combination group, and lymphedema occurred only in the exercise therapy group (n=6) 27. A randomised crossover study in ten patients with unilateral breast cancer-related arm lymphedema compared in maintenance therapy a device that mechanically mimics Manual Lymphatic Drainage with massage, each for one hour daily over 14 days, with a one-week washout phase 34.

Two pilot studies compare robot-assisted and manual supermicrosurgical lymphaticovenous anastomoses in breast cancer-related lymphedema. In the first, the outcome improved after three months in both groups, and operating time in the robot-assisted group fell from 33 to 16 minutes 26. The one-year evaluation included 20 women (eight robot-assisted, twelve manual): quality of life improved significantly in both groups (p=0.045 and p=0.001 respectively), arm circumference did not decrease (p=0.094 and p=0.240), and daily use of compression stockings fell by 61.9% 33. A randomised study of immediate lymphatic reconstruction after axillary lymph node dissection enrolled 72 patients each; in the preliminary evaluation the cumulative incidence was 9.5% versus 32% 20. These studies examine surgical procedures, not Manual Lymphatic Drainage.

Skin

The 2015 Cochrane review asks about the efficacy and safety of Manual Lymphatic Drainage in breast cancer-related lymphedema. It describes complex decongestive therapy as a four-part conservative treatment consisting of Manual Lymphatic Drainage, compression therapy (bandages, sleeves or other compression garments), skin care and lymph-reducing exercises; phase 1 serves decongestion, phase 2 maintenance. Included were randomised and quasi-randomised studies in women with breast cancer-related lymphedema; primary endpoints were volumetric changes and adverse events, secondary endpoints function, subjective sensations, quality of life and care costs 25.

Significant differences in favour of the virtual-reality group appeared in pain intensity, DASH and shoulder mobility (p<0.001), in bodily pain (p=0.002), general health (p<0.001) and vitality (p=0.006); differences also existed in shoulder flexion strength (p=0.002) 29. Because Manual Lymphatic Drainage was included in both arms, this study does not test its own effect.

A controlled study in 31 patients with upper-arm lymphedema after mastectomy compared complex decongestive physiotherapy (n=15) with the same therapy plus intermittent pneumatic compression (n=16); both groups were treated five times weekly over three weeks. A randomised study in 58 women with lymphedema after mastectomy compared standard treatment (skin care, exercise, compression measures, one month of bandaging, thereafter compression stockings; n=29) with standard treatment plus Manual Lymphatic Drainage (n=29), daily over four weeks, with follow-up after one, three and six months 35. A randomised pilot study in 41 patients compared decongestive therapy with short-stretch bandaging (n=21) with a variant in which kinesio tape replaced the bandage (n=20); each session comprised skin care, 30 minutes Manual Lymphatic Drainage, one hour pneumatic compression and 20 minutes exercise. No significant difference was found between the groups in any endpoint (P>0.05) 41.

The 2010 review evaluated ten randomised, one pseudo-randomised and four non-randomised studies on combined physiotherapy, intermittent pneumatic compression and arm elevation and considers combined physiotherapy effective, as well as arm bandaging 32. The 2015 review screened more than 160 studies and more than 20 reviews; the reviews consistently concluded that complex physiotherapy effectively reduces limb volume and reported volume reductions also after compression stockings, pumps and Manual Lymphatic Drainage, with the greatest improvements when used in combination 44. The review on yellow-nail syndrome lists short-stretch bandages, elastic compression stockings, skin care, exercises and Manual Lymphatic Drainage if required for the accompanying lymphedema 42.

Further Investigations

An exploratory pilot study used near-infrared fluorescence imaging to examine whether the effect of Manual Lymphatic Drainage can be measured. Ten persons with grade I or II lymphedema and twelve healthy controls received intradermal indocyanine green; images were taken before and after Manual Lymphatic Drainage. Mean apparent lymph velocity rose in the symptomatic (+23%) and asymptomatic (+25%) limbs of the affected persons as well as in the control limbs of healthy subjects (+28%); mean lymph propulsion period shortened in the symptomatic (-9%) and asymptomatic (-20%) limbs of the affected persons 40. The study shows a measurable physiological response to the treatment.

The 2018 review distinguishes lipedema from lymphedema. Lipedema is a rare, painful adipose-tissue disorder that predominantly affects women and is frequently misdiagnosed as lymphedema or obesity; it can progress into the venous and lymphatic systems. For treatment the work names weight reduction, oedema control, complex decongestive physiotherapy, liposuction and laser-assisted lipolysis, describing tumescent liposuction as the preferred surgical option with long-lasting results 28. Manual Lymphatic Drainage is not examined here as an independent intervention.

The 2018 anatomical review summarises the structure of the lymphatic system and the lymphatic pathways in the upper and lower extremities and introduces the concept of the “lymphosome”, according to which the lymphatic vessels of a region connect to the same subgroup of regional lymph nodes. It also describes the anatomical changes of the lymphatic vessels after lymph-node dissection in the context of secondary lymphedema 39. This work supplies the anatomical basis but does not examine Manual Lymphatic Drainage.

Inflammatory Processes

The 2018 review classifies lymphedema as a fundamentally immunological process that culminates in inflammation, fibroadipose deposition, impaired lymphangiogenesis and impaired lymph pump; up to one in six persons after treatment of a solid tumour is affected 36. The 2017 review describes lymphedema as a progressive inflammatory process with discomfort, recurrent infections and occasionally secondary malignancy; the histological hallmark is infiltration of inflammatory cells, which appears to play a key role in animal experiments and tissue samples 37.

The 2020 review works out the unresolved questions of pathophysiology: after impaired lymphatic drainage, proteins and lipids accumulate in the interstitial tissue, the tissue changes progressively with adipose-tissue deposition and fibrosis, accompanied by inflammation; the temporal sequence and interplay of these processes remain unclear 38. The 2020 molecular review estimates five million people in the United States with secondary lymphedema and describes inflammation, fibrosis, adipogenesis and recurrent infections as a cycle that further impairs lymphatic function 43.

The 2019 review on lymphatic function in autoimmune diseases addresses rheumatoid arthritis, scleroderma, lupus and dermatomyositis and considers the possibility that manual techniques such as massage and acupuncture could improve lymphatic function in autoimmune diseases 45. Hypothesis: This consideration is an open question; an examination of Manual Lymphatic Drainage in autoimmune diseases still stands out.

Gut and Microbiome

No study examining Manual Lymphatic Drainage exists for this field. Whether and how the procedure acts on the gut or microbiome is an open question; it could be clarified only by studies that test Manual Lymphatic Drainage itself.

Overall Picture

Across the fields a clear picture emerges: Manual Lymphatic Drainage has been broadly studied as a component of complex decongestive therapy, and the greatest volume reductions are reported when several procedures are combined 44. As the sole addition to complex therapy it shows no consistent additional benefit in several meta-analyses 1 2 11. For prevention after breast-cancer surgery the randomised studies yield differing results 18 30. Physiologically a response to the treatment can be measured: lymph velocity rises and propulsion period shortens 40.

At the outset research stands where Manual Lymphatic Drainage extends beyond breast cancer-related lymphedema. For lipedema, autoimmune diseases and gut or microbiome an examination of the procedure itself still stands out 28 45. The surgical neighbouring procedures of lymph surgery are tested in their own randomised studies 20 26 33, not Manual Lymphatic Drainage. The pathophysiology of lymphedema is well described in reviews 36 38 43, yet the transition from these mechanisms to concrete effects of Manual Lymphatic Drainage has not yet been examined.

3. How Reliable the Research Is

The research is clearly concentrated on one core area: oncological questions, predominantly lymphoedemas after breast cancer treatment, form the largest group of controlled studies in humans. This is followed by skin and musculoskeletal system, then safety, cognition and exhaustion as well as further areas. The field is thus built around a clinical core question, not arbitrarily broad. The citation structure is striking: at the top are works on pathophysiology, on the anatomy of the lymphatic system and on diseases of the lymphatic vessels, not on the manual technique. The most cited controlled works partly examine early physiotherapy for prevention, partly lymphatic drainage as an adjunct to compression. Some of the well-regarded studies also concern surgical procedures such as immediate lymphatic reconstruction and robot-assisted microsurgery; they belong to the broader field, not to the manual technique.

Methodologically the field rests on two pillars. On one side are randomised, partly single-blind controlled studies and several systematic reviews with meta-analysis that directly address the contribution of the manual technique to lymphoedema treatment after breast cancer. On the other side, observational studies predominate; these describe associations and do not provide evidence of causation. Blinding of the treated person is hardly possible with a manual technique; the studies therefore use blinded outcome assessment and standardised measurements. Follow-up periods and comparison conditions differ markedly between the studies. The independent effect of the technique has so far been examined directly in comparatively few controlled studies; this question remains open.

6. Summary

Proven In the summary of several meta-analyses, manual lymphatic drainage as an adjunct to complex decongestive therapy shows no consistent additional benefit. The 2013 meta-analysis evaluated ten randomised studies with 566 patients and found no significant difference either in incidence (risk ratio 0.63; 95% CI 0.14 to 2.82) or in arm volume reduction (weighted mean difference 75.12) (1). The 2020 meta-analysis included 17 randomised studies with 1911 patients; in the pooled analysis of eight studies with 338 patients, there was no significant reduction in lymphoedema (standardised mean difference -0.09) (2).

Plausible The pilot study with near-infrared fluorescence imaging shows a measurable physiological response to the treatment: The mean apparent lymph velocity increased by 23% in the symptomatic and 25% in the asymptomatic limbs of the affected individuals as well as by 28% in the control limbs of healthy subjects; the lymph propulsion period shortened by 9% and 20% respectively (41). Hypothesis: Such a response could explain why swelling values decrease under treatment; a clinical benefit does not necessarily follow from this. Hypothesis: The consideration in the 2019 review that manual procedures such as massage and acupuncture could improve lymph function in autoimmune diseases is also an open question (48).

Hypothesis A study that aimed to clarify the independent contribution of the manual technique would have to test manual lymphatic drainage in isolation or against a sham treatment, with blinded outcome assessment and standardised measurements as already used in the present studies. The comparison group would have to be clearly named: other treatment, sham treatment or no treatment. Endpoints would have to be kept separate — incidence, arm volume, shoulder function, pain and quality of life are not interchangeable, and a swelling value is a marker, not a disease course. It is also open whether and how the procedure affects the intestine or microbiome; for this area there is no study that has investigated manual lymphatic drainage.

7. What Remains Open

• Additional contribution: What proportion does the manual technique have when compression, skin care and exercise are kept constant in both groups? This question would be decided by a study with a sham-treated control group.
• Lipoedema: Does the course under manual lymphatic drainage in lipoedema differ from that in lymphoedema? A separate controlled series is pending for this.
• Endpoints: Which endpoint reflects the benefit — swelling, shoulder function, quality of life or pain? A study that defines all four in advance would establish the comparability of the studies.
