Does the speed of aquatic therapy exercise alter arm volume in women with breast cancer related lymphoedema? A cross-over randomized controlled trial

The effect of myofascial release in patients with breast cancer-related lymphedema: a cross-over randomized controlled trial

AIM

This study aimed to compare the effects of myofascial release (MFR) on upper extremity volume in patients with breast cancer-related lymphedema (BCRL).

DESIGN

A randomized, single-blinded, cross-over, controlled trial.

SETTING

An outpatient rehabilitation clinical setting.

POPULATION

Thirty patients with BCRL.

METHODS

Within a crossover design with randomized treatment sequences, fifteen subjects received MFR for 4 weeks, followed by 4 weeks of washout period, and then received placebo MFR and the other fifteen subjects received interventions in the reverse order. Each session had a 60 min process including either MFR or placebo MFR for 30 min, followed by complete decongestive therapy for 30 min twice a week. Upper limb volume as the primary outcome and subjective pain, shoulder range of motion (ROM), chest mobility, shoulder function, and quality of life as secondary outcomes were assessed before and at the end of each intervention period.

RESULTS

There were significant differences in upper limb volume after both MFR and placebo MFR (P<0.05) while no significant difference between MFR and placebo MFR treatments was found (P>0.05). MFR-based treatment also achieved a greater improvement than placebo MFR-based treatment in subjective pain and shoulder ROM (P<0.05), except for internal rotation, and shoulder function.

CONCLUSIONS

MFR-based treatment showed clinical improvement in shoulder function, induced by decreased edema volume and pain, and improved ROM and chest mobility. However, a further study with parallel randomized controlled trials to confirm what was achieved in the present study.

CLINICAL REHABILITATION IMPACT

MFR-based treatment is considered an important part of BCRL rehabilitation. Moreover, MFR-based treatment may be safe for patients with BCRL.

Water-based exercise for upper and lower limb lymphedema treatment

BACKGROUND

Lymphedema is a debilitating illness caused by insufficient lymph drainage, which can have serious physical and psychological consequences. Although water-based exercise can be useful, at present, little evidence is available regarding the outcomes of aquatic treatment for patients with lymphedema. Therefore, the aim of the present scoping review was to evaluate, from reported studies, the effects of water-based exercise on pain, limb motor function, quality of life (QoL), and limb volume among patients affected by primary and secondary upper and lower limb lymphedema.

METHODS

We performed a scoping review to examine clinical studies and randomized controlled trials reported in English from 2000 to 2021 by screening the MEDLINE (PubMed) and PEDro databases.

RESULTS

The search produced a total of 88 studies. Eight randomized controlled trials and one clinical study of patients with primary or secondary lymphedema of upper or lower limbs who had undergone water-based treatment were included in the present study. Most trials had focused on breast cancer-related lymphedema. The shoulder range of flexion, external rotation, and abduction have been shown to improve after performing a water-based exercise protocol. Some evidence has also demonstrated that the lymphedematous limb strength can improve. Moreover, water-based exercise seemed to improve pain perception and QoL for patients with upper or lower limb lymphedema. In contrast, in the control groups, the QoL showed a tendency to worsen over time. Although some studies had not reported beneficial effects on the lymphedematous limb volume, most of the studies examined had reported a reduction in volume, especially in the short term. No adverse events were reported in the included studies.

CONCLUSIONS

The findings from the present review have shown the potential for aquatic exercise in lymphedema management. However, at the same time, the findings underline the multiple limitations resulting from the heterogeneity in the study populations and related physical activity protocols. The role of aquatic exercise in the conservative treatment of lymphedema requires further investigation in the future to define specific protocols of application.

The Effect of Exercise for the Prevention and Treatment of Cancer-Related Lymphedema: A Systematic Review with Meta-analysis

INTRODUCTION

The purpose of this systematic review and meta-analysis was to evaluate the effects of exercise on (i) the prevention of cancer-related lymphedema (CRL) and (ii) the treatment of CRL, lymphedema-associated symptoms, and other health outcomes among individuals with CRL.

METHODS

An electronic search was undertaken for exercise studies measuring lymphedema and involving individuals at risk of developing or with CRL. The Effective Public Health Practice Project Quality scale was used to assess study quality, and overall quality of evidence was assessed using the Grading of Recommendation, Assessment, Development and Evaluation approach. Meta-analyses were performed to evaluate effects of exercise on CRL incidence, existing CRL status, lymphedema-associated symptoms, and health outcomes.

RESULTS

Twelve studies ( n = 1955; 75% moderate-high quality) and 36 studies ( n = 1741; 58% moderate-high quality) were included in the prevention and treatment aim, respectively. Relative risk of developing CRL for those in the exercise group compared with the nonexercise group was 0.90 (95% confidence interval (CI), 0.72 to 1.13) overall and 0.49 (95% CI, 0.28 to 0.85) for those with five or more lymph nodes removed. For those with CRL in the exercise group, the standardized mean difference (SMD) before to after exercise of CRL was -0.11 (95% CI, -0.22 to 0.01), and compared with usual care postintervention, the SMD was -0.10 (95% CI, -0.24 to 0.04). Improvements after intervention were observed for pain, upper-body function and strength, lower-body strength, fatigue, and quality of life for those in the exercise group (SMD, 0.3-0.8; P < 0.05).

CONCLUSIONS

Findings support the application of exercise guidelines for the wider cancer population to those with or at risk of CRL. This includes promotion of aerobic and resistance exercise, and not just resistance exercise alone, as well as unsupervised exercise guided by symptom response.

Water therapies (hydrotherapy, balneotherapy or aqua therapy) for patients with cancer: a systematic review

Background

Water therapies as hydrotherapy, balneotherapy or aqua therapy are often used in the relief of disease- and treatment-associated symptoms of cancer patients. Yet, a systematic review for the evidence of water therapy including all cancer entities has not been conducted to date.

Purpose

Oncological patients often suffer from symptoms which in patients with other diseases are successfully treated with water therapy. We want to gather more information about the benefits and risks of water therapy for cancer patients.

Method

In May 2020, a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL and PubMed) to find studies concerning the use, effectiveness and potential harm of water therapy on cancer patients.

Results

Of 3165 search results, 10 publications concerning 12 studies with 430 patients were included in this systematic review. The patients treated with water therapy were mainly diagnosed with breast cancer. The therapy concepts included aqua lymphatic therapy, aquatic exercises, foot bathes and whole-body bathes. Outcomes were state of lymphedema, quality of life, fatigue, BMI, vital parameters, anxiety and pain. The quality of the studies was assessed with the AMSTAR2-instrument, the SIGN-checklist and the IHE-Instruments. The studies had moderate quality and reported heterogeneous results. Some studies reported significantly improved quality of life, extent of lymphedema, neck and shoulder pain, fatigue and BMI while other studies did not find any changes concerning these endpoints.

Conclusion

Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of water therapy on cancer patients is not possible.

Effect of Aqua Therapy Exercises on Postmastectomy Lymphedema: A Prospective Randomized Controlled Trial

Objective

To investigate the effect of aqua therapy resistance exercise on arm volume, pain, and shoulder range of movements in post-mastectomy lymphedema.

Methods

This was a single-blind randomized controlled trial. Fifty eligible breast cancer survivors (median, 10 years after surgery) with lymphedema (median, 21% inter-limb difference) were assigned randomly to group A (n=25) or control group B (n=25). The study group underwent 60 minutes of aqua therapy exercise comprising of warm-up for 10 minutes, 40 minutes of strengthening exercises, and 10 minutes of cooling down, three times a week for 8 weeks. The control group underwent 60 minutes of land-based exercise three times a week for 8 weeks. Arm volume calculated by measuring the arm circumference, shoulder flexion, and abduction range of motion (ROM), and pain using a visual analog scale (VAS) were assessed at baseline and after 8 weeks of treatment.

Results

There was a statistically significant difference in limb volume, shoulder flexion and abduction ROM, and VAS scores in favor of the study group (p<0.001) after 8 weeks of intervention. The mean±standard deviation for limb volume, shoulder flexion, abduction, and pain score were 2,108.71±200.97 mL, 169.68°±4.54°, 150.44°±3.92°, and 3.16±1.1 in the study group and 2,256.41±186.94 mL, 147.36°±5.32°, 131.32°±4.38°, and 5.68±0.94 in the control group, respectively.

Conclusion

Adding aqua therapy resistance exercise to routine physical therapy might be more effective in decreasing the limb volume and pain intensity and improving ROM of the shoulder in postmastectomy lymphedema.

Effects of 12 weeks of water aerobics on body composition in those affected by breast cancer

Exercise may prevent changes in body composition and provide an effective means of improving the side effects of treatment without causing lymphedema.

PURPOSE

Test the effectiveness of a 12-week water aerobics program on body composition and lymphedema risk in breast cancer survivors.

METHODS

Body composition analysis was completed at weeks 0, 6, and 12 weeks.

RESULTS

Ten females completed all testing. Baseline subject characteristics were as follows: age (59.40 ± 8.22 years), weight (169.91 ± 41.70 lbs), body fat percent (%BF) (40.15 ± 9.84%), body fat mass (BFM) (71.27 ± 31.50 lbs), lean body mass (LBM) (98.66 ± 13.24 lbs), skeletal muscle mass (SMM) (53.17 ± 8.09 lbs), intracellular water (ICW) (44.24 ± 6.18 lbs), and extracellular water (ECW) (28.91 ± 3.62 lbs). One-way ANOVA showed no statistically significant differences over time as determined for weight (F(2.27) = 0.002, P = 0.96), %BF (F(2.27) = 0.004, P = 0.97), BFM (F(2.27) = 0.001, P = 0.97), LBM (F(2.27) = 0.013, P = 0.95), SMM (F(2.27) = 0.027, P = 0.91), ICW (F(2.27) = 0.021, P = 0.93), and ECW (F(2.27) = 0.01, P = 0.94) across the 12 weeks.

CONCLUSIONS

A water aerobics program for 12 weeks was not enough to observe changes in body composition nor did it increase the risk for lymphedema and may be a safe exercise method for breast cancer survivors.

Comparing the experience of individuals with primary and secondary lymphoedema: A qualitative study

BACKGROUND

Lymphoedema is a chronic condition that has significant detrimental impact on patients' quality of life. Secondary lymphoedema often results from anti-tumour treatment, in contrast to primary lymphoedema which is the result of genetic abnormalities that leads to an abnormal development of the lymphatic system.

OBJECTIVE

To describe and compare the experience of individuals with primary and secondary lymphoedema.

METHODS

A total of 19 patients (mean ± standard deviation age: 56.7 ± 16.2 years), 8 with primary and 11 with secondary lymphoedema, participated in this qualitative phenomenological study. Purposeful sampling method was applied. We recruited participants from specialised lymphoedema units of two physical therapy clinics and the Lymphoedema Patient Association in Spain. Data collection methods included unstructured and semi-structured interviews. An inductive thematic analysis was used.

RESULTS

The findings suggest differences between the experience of living with primary or secondary lymphoedema. Also, those with lower extremity lymphoedema have more pain, fatigue, and functional limitations. Three primary themes emerged: "Emotional challenge", "Adapting your life to a new situation," and "lymphoedema management".

CONCLUSIONS

The experience of living with lymphoedema involves aspects of fear, suffering, coping, and management of the disease and differs between secondary and primary causes. However, it seems to be more dependent on its location than its cause.
