Hemodynamic Responses in Lower Limb Lymphedema Patients Undergoing Physical Therapy

BACKGROUND

Lymphedema arises due to a malfunction of the lymphatic system, leading to extensive tissue swelling. Complete decongestive therapy (CDT), which is a physical therapy lasting for 3 weeks and includes manual lymphatic drainages (MLD), leads to fluid mobilization and increases in plasma volume. Here, we investigated hemodynamic responses induced by these fluid shifts due to CDT and MLD.

METHODS

Hemodynamic parameters were assessed continuously during a sit-to-stand test (5 min baseline, 5 min of standing, and 5 min of recovery). This intervention was repeated on days 1, 2, 7, 14, and 21 of CDT, before and after MLD. Volume regulatory hormones were assessed in plasma samples.

RESULTS

A total number of 13 patients took part in this investigation. Resting diastolic blood pressure significantly decreased over three weeks of CDT (p = 0.048). No changes in baseline values were shown due to MLD. However, MLD led to a significant decrease in heart rate during orthostatic loading over all epochs on therapy day 14, as well as day 21. Volume regulatory hormones did not show changes over lymphedema therapy.

CONCLUSION

We did not observe any signs of orthostatic hypotension at rest, as well as during to CDT, indicating that lymphedema patients do not display an elevated risk of orthostatic intolerance. Although baseline hemodynamics were not affected, MLD has shown to have potential beneficial effects on hemodynamic responses to a sit-to-stand test in patients undergoing lymphedema therapy.

PHYSICAL THERAPY AFFECTS ENDOTHELIAL FUNCTION IN LYMPHEDEMA PATIENTS

Lymphedema arises due to a malfunction of the lymphatic system and can lead to massive tissue swelling. Complete decongestive therapy (CDT), consisting of manual lymphatic drainage (MLD) and compression bandaging, is aimed at mobilizing fluid and reducing volume in affected extremities. Lymphatic dysfunction has previously been associated with chronic inflammation processes. We investigated plasma ADMA as an indicator of endothelial function/inflammation before-, during- and after-CDT. Also assessed were vascular function parameters such as carotid-femoral pulse wave velocity (PWVcf), flow-mediated dilatation (FMD) and retinal microvasculature analysis. 13 patients (3 males and 10 females, 57 ± 8 years old (mean ± SD), 167.2 ± 8.3 cm height, 91.0 ± 23.5 kg weight), with lower limb lymphedema were included. Vascular function parameters were assessed on day 1, 2, 7, 14 and 21 of CDT, pre- and post-MLD. ADMA was significantly lower post-MLD (p=0.0064) and tended to reduce over three weeks of therapy (p=0.0506). PWVcf weakly correlated with FMD (r=0.361, p=0.010). PWVcf, FMD and retinal microvasculature analysis did not show changes due to physical therapy. The novel results from this study indicate that lymphedema does not affect endothelial function and lymphedema patients may therefore not have a higher risk of cardiovascular diseases. Our results further suggest that manual lymphatic drainage with or without full CDT could have potentially beneficial effects on endothelial function in lymphedema patients (by reducing ADMA levels), which has not been reported previously.

Effects of physical therapy on hyaluronan clearance and volume regulating hormones in lower limb lymphedema patients: A pilot study

Lymphedema is manifested as a chronic swelling arising due to stasis in the lymphatic flow. No cure is currently available. A non-invasive treatment is a 3 week complete decongestive therapy (CDT), including manual lymphatic drainage and compression bandaging to control swelling. As CDT leads to mobilization of several liters of fluid, effects of CDT on hyaluronan clearance (maker for lymphatic outflow), volume regulating hormones, total plasma protein as well as plasma density, osmolality and selected electrolytes were investigated. In this pilot study, we assessed hyaluronan and volume regulating hormone responses from plasma samples of nine patients (three males, six females, aged 55 ± 13 years) with lower limb lymphedema stage II-III, before - and after - CDT. A paired non-parametric test (Wilcoxon) was used to assess hormonal and plasma volume changes. Correlation was tested using Spearman's correlation. The main findings of this novel study are that lymphedema patients lost volume and weight after therapy. Hyaluronic acid did not significantly change pre- compared to post-CDT. Aldosterone increased significantly after therapy, while plasma renin activity increased, but not significantly. Plasma total protein, density, osmolality and sodium and chloride did not show differences after CDT. To our knowledge, no study has previously investigated the effects of CDT on volume regulating hormones or electrolytes. To identify the time-course of volume regulating hormones and lymphatic flow changes induced by CDT, future studies should assess these parameters serially over 3 weeks of therapy.

[Treatment for chronic back pain? : Active multimodal, interdisciplinary pain therapy vs. physiotherapy-physical therapy for chronic back pain]

BACKGROUND

In industrialized countries, chronic back pain is referred to as the "number one common disease".

OBJECTIVES

Are there any indications of different outcomes of chronic back pain patients when treated with a multimodal, interdisciplinary pain therapy (MMSTh) compared to physiotherapy-physical therapy?

MATERIALS AND METHODS

Entrance and final examination by means of survey, questionnaires and physical tests in the intervention and control group, evaluation and comparison of the results.

RESULTS

The intervention group showed very significant improvements in all tests. In contrast, the control group achieved only partial improvements in physical parameters and quality of life. This resulted in clear group differences in favor of the MMSTh. In terms of patient satisfaction, the control group showed a better result than the intervention group.

CONCLUSIONS

Treatment with MMSTh is superior to standard physiotherapy-physical. Due to the extensive, proven positive effect on many pain-causing and pain-preserving factors, multimodal pain centers should be used more frequently in chronic back pain patients.

[Conservative lymphedema therapy - lymphological rehabilitation treatment]

The most important column in the conservative lymphedema therapy still represents the complex decongestive physical therapy/KPE.This is a multimodal therapy, which consists of four components. (1) skin restoration and/or skin care, (2) manual lymphatic drainage, (3) compression therapy and (4) decongestive exercises. The KPE is also divided into two phases. Phase 1-the decongestion-serves primarily the mobilization and transporting away the banked protein-rich oedema fluid and seamless transition into the Phase 2-the maintenance phase, which serves to preserve the achieved treatment success. The implementation of the KPE should be stage-adjusted, but depends also on the location (genital, head, face), and on co-existing comorbidities (congestive heart failure, diabetes mellitus, obesity, muscular-skeletal disorders, mental illness, etc.). It should be modified for children, elderly persons and for patients with malignant lymphedema.
