Effects of Exercise Training on Restless Legs Syndrome, Depression, Sleep Quality, and Fatigue Among Hemodialysis Patients: A Systematic Review and Meta-analysis

Correlation Between Symptom Clusters and Self-Management Among Maintenance Haemodialysis Patients: A Cross-Sectional Study

AIMS AND OBJECTIVES

The purpose of this study was to explore the relationship between symptom clusters and self-management among maintenance haemodialysis (MHD) patients.

BACKGROUND

MHD patients experience disease progression and multiple symptom burdens that severely impact quality of life, and self-management of symptoms may significantly improve patient-reported outcomes.

DESIGN

A cross-sectional study.

METHODS

This cross-sectional descriptive study included 194 patients undergoing MHD. The patients were assessed using the Dialysis Symptom Index (DSI) and the Haemodialysis Self-Management Instrument (HD-SMI). We used descriptive analysis, exploratory factor analysis, Pearson's correlation analysis and linear regression analysis to examine (1) the level of individual self-management, (2) the presence of symptom clusters by symptom severity and (3) the correlation between symptom clusters and self-management behaviours. This study was conducted in accordance with the STROBE checklist.

RESULTS

The top five most severe symptoms among the patients were itching, feeling tired or lack of energy, difficulty sleeping, dry mouth and dry skin. We identified five groups of symptoms: (1) poor sleep, (2) neuromuscular, (3) gastrointestinal, (4) skin irritation and (5) psychological. In the present study, MHD patients reported low to moderate levels of self-management behaviours (50.84 ± 10.56), and low self-management ability was correlated with greater severity of the five symptom clusters (p < 0.01). Linear regression analysis revealed that all five symptom clusters were included in the regression equation, explaining 30% of the total variance in self-management skills among MHD patients.

CONCLUSION

Enhanced awareness of symptom clusters and comprehensive symptom management are necessary to improve patients' quality of life.

CLINICAL RELEVANCE

Nursing practices should incorporate comprehensive symptom assessments to help patients develop effective self-management strategies to improve quality of life.

The effectiveness of relaxation exercises on fatigue in hemodialysis patients: a meta-analysis study

OBJECTIVE

This study was conducted to determine the effect of relaxation exercise on fatigue symptoms in hemodialysis patients.

METHODS

This is a meta-analysis study. The literature review was carried out by searching studies published between 2011 and 2020. This meta-analysis was recorded on PROSPERO in the National Health Research Institute (Registration no: CRD42022313646).

RESULTS

Seven studies meeting the inclusion criteria were included in the meta-analysis. The effect size of the studies included in the meta-analysis was found to be g=1.232 (p=0.028), which indicated a "huge effect size." The scale used in the subgroup analyses, the application time of the relaxation exercise, and the number of relaxation exercise applications were evaluated, and a significant difference was found at p<0.05.

CONCLUSION

Relaxation exercises can be used as an effective method for reducing fatigue in hemodialysis patients.

Unfolding the role of exercise in the management of sleep disorders

Sleep disorders are prevalent among the general population and even more in individuals suffering from chronic diseases. Recent data reveal promising effects of physical exercise as a non-pharmacological approach for improving sleep and managing various sleep disorders. However, more studies with proper design and methodology should be conducted in the future to obtain a clearer understanding of the subject. The role of exercise in preventing and improving sleep disorders is probably much higher than what is currently exploited. To fully exploit the potential benefit of physical activity on sleep disorders in the future, it is necessary to identify the relevant tools to assess sleep-wake disorders and establish specific exercise protocols tailored to different sleep disorders. The present manuscript aims to review the literature on the use of exercise in managing selected sleep disorders. Regular exercise, including short-term aerobic activity, resistance training, and mind-body exercises, can effectively improve sleep quality, particularly in cases of insomnia and sleep-disordered breathing. Additionally, increasing evidence supports the effectiveness of aerobic and strength training, and body-mind exercises such as yoga in managing sleep-related movement disorders. Exercise can be a safe, affordable, and efficient tool in enhancing sleep quality and improving sleep disorders. Per se, regular exercise could play an adjuvant role alongside with established therapies, or a valid alternative when the pharmacological approach is limited by side effects, interactions, or inefficacy. More research is needed to define how exercise affects the physiology of sleep, and consequently how to use exercise in patients with sleep disorders.

Exercise, Dialysis, and Environment: A Narrative Review in an Ecological Perspective

BACKGROUND

Patient empowerment and environmental sustainability may contribute to creating efficient and resilient healthcare models. Chronic kidney diseases call for a sustainable approach aimed at improving physical function and mental health of patients and possibly contributing to the slowing down of the evolution toward the end stage of renal disease (ESRD) with a reduction of the environmental and economic impact.

SUMMARY

Multidisciplinary interventions should be implemented particularly, at the final stages when patients are exposed to sedentariness, reduced health-related quality of life (HR-QoL), high cardiovascular morbidity and mortality, and the healthcare services to high costs, and participation in environmental pollution. Ecological strategies based on specific nutritional approaches, exercise, and environment should be designed and tested. In particular, the introduction to physical exercise represents a useful replacement therapy to counteract the hazards derived from the sedentary behavior of ESRD patients, with low physical function associated with poor clinical outcomes. A more active and healthy lifestyle, particularly in the natural environment, could impact HR-QoL, mental and physical well-being but also on socialization, with lower anxiety and fatigue stress levels. Otherwise, combining sustainable exercise models into the patient's daily routine can be enhanced by the biophilic design called to reproduce a natural environment in the dialysis center. Finally, the involvement of the personnel and the health professionals in properly managing the exercise interventions and the related factors (location, modality, dose, intensity, and duration) might improve the patients' participation. In particular, ecological programs should be broadly inclusive and aimed to target the lowest performing populations through minimal feasible doses of exercise.

KEY MESSAGES

Moving toward an ecological framework of lifestyle change in the very advanced stages of kidney disease, the potential synergies between environment, diet, and exercise may improve the physical and mental health of the patients and reduce the impact of dialysis.

Effect of Exercise on Fatigue in Patients Receiving Maintenance Hemodialysis Treatment: A Systematic Review and Network Meta-analysis

OBJECTIVE

This study aimed to evaluate the effect of different exercises for improving fatigue in maintenance hemodialysis patients.

DESIGN

PubMed, Embase, Web of Science, Cochrane, PEDro, CNKI, VIP, Wanfang data, CBM, and CINAHL were conducted from the establishment of the database to July 2023. We independently screened the literature, evaluated the quality, analyzed the data using Stata 15.0, and performed subgroup analysis on intervention time and exercise intervention adherence.

RESULTS

Twenty-three studies were analyzed, with 1867 patients and nine interventions. Based on the surface under cumulative ranking curves and pairwise comparisons effects, overall long-term, short-term, and exercise intervention adherence >90% effects have all presented that during dialysis aerobic-resistance combined exercise was ranked as the most effective compared with routine care (surface under cumulative ranking curves = 83.9%, standardized mean difference = -1.45, 95% CI = -2.23 to -0.67; surface under cumulative ranking curves = 85.9%, standardized mean difference = -1.38, 95% CI = -2.24 to -0.52; surface under cumulative ranking curves = 86.6%, standardized mean difference = -1.54, 95% CI = -2.58 to -0.49; surface under cumulative ranking curves = 83.6%, standardized mean difference = -1.45, 95% CI = -2.25 to -0.66, respectively), followed by interdialytic period muscle relaxation exercise, interdialytic period aerobic-resistance combined exercise, interdialytic period aerobic exercise, and interdialytic period Baduanjin.

CONCLUSIONS

Dialysis aerobic-resistance combined exercise may be considered in practice when resources allow. However, high-quality, multicenter, and large-sample randomized control trials must further verify this conclusion.

A Current State of the Art and Science of Exercise in Dialysis: A Narrative Review

Purpose of the review

The purpose of the review is to discuss current proven benefits and problems of integrating exercise in the care of people receiving dialysis by reviewing literature from the last few years and identifying important questions that still need to be asked and answered.

Methods

A focused review and appraisal of the literature were done. Original peer-reviewed articles, review articles, opinion pieces and guidelines were identified from PubMed and Google Scholar databases. Only sources in English were accessed. Search terms "exercise" and "dialysis" were used to find active recruiting randomized trials in various clinical trial registry platforms.

Key findings

Numerous studies have demonstrated the benefits of exercise training in individuals receiving dialysis, limited by factors such as short duration of follow-up and inconsistent adverse event reporting and outcomes selected. Notable gaps in exercise research in dialysis include ways to maintain programs and patient motivation, studies in peritoneal dialysis and home hemodialysis patients, and how best to define and measure outcomes of interest.

Implications

This review summarizes the current state of exercise in people receiving dialysis and serves as a call to action to conduct large, randomized controlled trials to improve the quality of evidence needed to implement and sustain innovative, exercise interventions, and programs for this population.

Renal Rehabilitation: Present and Future Perspectives

Chronic kidney disease (CKD) is a global health problem. In patients with CKD, exercise endurance is decreased, especially as renal dysfunction advances. This is due to the combined effects of protein-energy wasting, uremic acidosis, and inflammatory cachexia, which lead to sarcopenia and are aggravated by a sedentary lifestyle, resulting in a progressive downward spiral of deconditioning. Renal rehabilitation (RR) is a coordinated, multifaceted intervention designed to optimize a patient's physical, psychological, and social functioning, as well as to stabilize, slow, or even reverse the progression of renal deterioration, improving exercise tolerance and preventing the onset and worsening of heart failure, thereby reducing morbidity and mortality. This review focused on the history and benefits of RR in patients with CKD. Based on current evidence, RR is an effective, feasible, and safe secondary prevention strategy in CKD. RR is a promising model for a new field of rehabilitation. Therefore, efforts to increase RR implementation rates are urgently needed.

Influence of Regular Physical Activity on Sleep

Good sleep and adequate physical activity are essential to health. Yet, large numbers of people are chronically deficient in sleep and physical activity. About 1 in 3 Americans get less than 7 h of sleep per night and only 1 of 4 adults regularly complete weekly physical activity in amounts recommended for good health. This chapter reviews research that has examined relationships between regular physical activity and sleep. The overall weight of evidence supports that regular physical activity is associated with better sleep quality among healthy adults, with epidemiological studies showing moderate-sized effects and more well-controlled randomized controlled trial experiments often showing larger effects. Large epidemiology studies suggest that the relationship between regular physical activity and better sleep quality may partially mediate the well-established associations between physical activity and reduced risk of mortality, cardiovascular diseases, and dementia. There is evidence that the completion of regular physical activity also is associated with better sleep quality among those with certain sleep disorders (i.e., insomnia, obstructive sleep apnea, and restless legs syndrome), mental health disorders (i.e., depression and posttraumatic stress disorder), and medical illnesses (i.e., breast cancer survivors). The evidence is inadequate to support that regular physical activity substantially improves sleep quality either (i) in children, adolescents, and older adults, (ii) in those with cancers except for breast cancer, (iii) in those with fibromyalgia, or (iv) among those with chronic kidney disease. Also, there is inadequate evidence to conclude that sleep quality is disrupted during weeks when competitive athletes engage in periods of overtraining.

Effectiveness of exercise and pramipexole in the treatment of restless leg syndrome: Implications on the dopaminergic system and PTPRD

OBJECTIVE

Dopaminergic dysfunction, iron reduction and variations in the PTPRD gene (protein tyrosine phosphatase receptor type delta) may be associated with restless leg syndrome (RLS). Here, we evaluate the effect of pramipexole (PPX) and exercise on genes and proteins associated with RLS and on sleep patterns in spontaneously hypertensive rats (SHR).

METHODS

Animals were distributed into 4 groups: 1) Control (CTRL); 2) Exercise (EX); 3) Exercise and pramipexole (EX + PPX); and 4) Pramipexole (PPX). PPX treatment was performed daily (0.125 mg/kg), while exercise was conducted over 5 sessions per week, both for 4 weeks.

RESULTS

EX + PPX increased the protein levels of PTPRD, reduced the protein levels of the enzyme tyrosine hydroxylase (TH) and improved sleep parameters in both cycles; on the other hand, the use of PPX reduced mRNA and protein levels of PTPRD and TH but improved the sleep pattern in the light cycle. However, in the dark cycle, pramipexole caused the worsening of symptoms.

CONCLUSIONS

We suggest that the improvement in sleep pattern by EX + PPX may be associated with the increased protein levels of PTPRD and that EX + PPX can reverse the negative effects of PPX.

Sleep Quality and Its Affecting Factors among Hemodialysis Patients: A Multicenter Cross-Sectional Study

(1) Background: Sleep quality is one of the most important clinical outcomes of hemodialysis (HD) patients, as it can affect their physical and mental health. This study aimed to investigate sleep quality and its affecting factors among patients with HD. (2) Methods: A cross-sectional design was used to investigate the quality of sleep among HD patients in two cities in Saudi Arabia. The data were collected during the period from January to December 2022. A convenience sample of 250 HD patients was selected in this study. Data were collected using the Arabic version of the Pittsburgh Sleep Quality Index (PSQI). (3) Results: About two-thirds of participants (63.6%) had normal sleep, while one-third had poor sleep (36.4%). There was a significant relationship between the participants' age and the quality of sleep, where participants who were aged more than 50 had poorer sleep than those who were younger (p < 0.001). Male and married participants significantly had poor sleep more than female and single participants (p = 0.011 and 0.015, respectively). In addition, participants who were retired, had a higher number of dependents, did not adhere to exercise, and had more comorbidities had significantly poorer sleep than other groups (p = 0.002, 0.016, 0.023, and <0.001, respectively). The level of education, financial status, distance from home to dialysis center, and participants' satisfaction at the time of dialysis had no influence on the quality of sleep among HD patients. The multiple linear regression shows that exercise (p = 0.017), the number of comorbidities (p = 0.008), and the duration of dialysis (p < 0.020) were the independent factors affecting the quality of sleep among HD patients. (4) Conclusions: About one-third of HD patients in this study had poor sleep. There were significant differences between patients' age, gender, marital status, and sleep-quality levels. Moreover, participants who retired, had a higher number of dependents, did not adhere to exercise, and had more comorbidities had significantly poorer sleep than other groups. Future studies should develop appropriate interventions to address the problem of poor sleep quality among HD patients.

Effects of Different Exercise Programs on Symptoms, Sleep, and Quality of Life in Patients with Primary Restless Legs Syndrome

Background

Restless legs syndrome (RLS) is a sensorimotor disorder that can have a significant detrimental impact on the quality of life and sleep.

Objectives

Our aim was to examine the effects of aerobic exercise and stretching exercise programs on symptom severity, sleep, and quality of life in patients with primary RLS.

Methods

A total of 18 patients between the ages of 22 and 61 were randomly divided into 3 groups as aerobic exercise, stretching exercises, and control. All exercise programs were applied 3 times a week for 8 weeks. Evaluations were performed before and after treatment. Symptom severity of the patients was evaluated by the International Restless Legs Syndrome Study Group Rating Scale, sleep was evaluated with the Pittsburgh Sleep Quality Index and actigraphy, and quality of life was evaluated with the John Hopkins Restless Legs Syndrome Quality of Life Questionnaire. Recovery status of the patients was determined using the post treatment global change scale.

Results

Aerobic exercise and the stretching exercise program were found to be effective in decreasing RLS symptoms (P = 0.025, P = 0.034) and improving subjective sleep quality (P = 0.034, P = 0.025), overall sleep quality (P < 0.001, P = 0.034), and quality of life (P = 0.009, P = 0016). Aerobic exercises were found to be more effective in reducing wake after sleep onset of sleep (P = 0.048), whereas stretching exercises reduced sleep disorders (P = 0.025).

Conclusion

Both exercise approaches have been identified as highly effective approaches in patients with RLS. The treatment can be planned according to the choice of the available facilities, patient and clinician preference, and the advantages of the 2 exercise approaches.

Interventions for fatigue in people with kidney failure requiring dialysis

BACKGROUND

Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD).

OBJECTIVES

We aimed to evaluate the effects of pharmacological and non-pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Studies evaluating pharmacological and non-pharmacological interventions affecting levels of fatigue or fatigue-related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue-related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered.

DATA COLLECTION AND ANALYSIS

Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

MAIN RESULTS

Ninety-four studies involving 8191 randomised participants were eligible. Pharmacological and non-pharmacological interventions were compared either to placebo or control, or to another pharmacological or non-pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high. In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis-Related Fatigue scale score): SMD -1.18, 95% CI -2.04 to -0.31; I2 = 87%) in HD. In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD -1.23, 95% CI -1.96 to -0.50; I2 = 93%) in HD. In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD -1.06, 95% CI -1.47, -0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD. In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD -0.64, 95% CI -1.03 to -0.25; I2 = 75%) in HD. A wide range of heterogenous interventions and fatigue-related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data. Due to the paucity of studies, the effects of pharmacological and other non-pharmacological interventions on fatigue or fatigue-related outcomes, including non-physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive-behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta-blockers, anabolic steroids, glucose-enriched dialysate, or light therapy, were very uncertain. The effects of pharmacological and non-pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported.

AUTHORS' CONCLUSIONS

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non-pharmacological interventions had uncertain effects on fatigue or fatigue-related outcomes in people receiving dialysis. Future adequately powered, high-quality studies are likely to change the estimated effects of interventions for fatigue and fatigue-related outcomes in people receiving dialysis.

Global research trends and mapping knowledge structure of depression in dialysis patients

BACKGROUND

Depression is one of the most common and important psychological issues faced by dialysis patients. It can make it more difficult for them to adhere to their treatment regimen, which, in turn, can worsen their physical symptoms and lead to poorer health outcomes.

AIM

To examine the evolution and growth of publications related to dialysis and depression. The objectives were to identify the number of publications, the top active countries, the contributed institutions, funding agencies and journals, as well as to perform citation and research theme analysis.

METHODS

The search was conducted using the Scopus database for publications related to dialysis and depression between 1970 and 2022. Subsequently, bibliometric analysis was carried out on the data obtained using VOSviewer software, version 1.6.9. This analysis included visualization analysis, co-occurrence analysis and examination of publication trends in dialysis and depression.

RESULTS

We identified 800 publications that met the search criteria. The number of publications related to dialysis and depression has increased significantly in the past two decades. The USA led the way with 144 publications, which is 18% of all publications on this topic. Turkey came second with 88 publications (11%), followed by China with 55 publications (6.88%) and Iran with 52 publications (6.5%). Analysis of the research theme identified three main clusters related to gender differences in prevalence, identification of depression as a risk factor, and effective interventions to relieve depression. Future research direction analysis shows a shift toward effective interventions to relieve depression in dialysis patients.

CONCLUSION

This study provides a comprehensive overview of growth, trends and research themes related to dialysis and depression that could help researchers identify gaps in the literature and develop future research.

The effects of virtual reality-based exercise in adults receiving haemodialysis treatment: A systematic review and meta-analysis of randomized controlled studies

This meta-analysis aimed to synthesize the effects of virtual reality-based exercise on physical function, depression symptoms and quality of life in adults receiving haemodialysis. Data were analysed using Comprehensive Meta-Analysis Version 3. The random-effects meta-analysis was performed to pool intervention effects. A total of five studies were included. The majority of included studies compared intervention with passive control group. This meta-analysis showed with a moderate to high quality of evidence that virtual reality-based exercise has positive medium effect on improving physical function such as gait speed (g = .40, 95% CI 0.00 to 0.81), sit to stand 10 times (g = -.41, 95% CI -0.825 to -0.009), sit to stand in 60 s (g = .56, 95% CI 0.151 to 0.974), 6-min walk test (g = .66, 95% CI 0.247 to 1.079), not affect time up and go and sit to stand five times. The study indicated with moderate quality of evidence that virtual reality-based exercise had no effect on depression symptoms. The study also showed with a moderate quality of evidence that the intervention had a positive medium effect on improving physical function (g = .64, 95% CI 0.20 to 1.09). In conclusion, virtual reality-based exercise can be performed to improve physical function and quality of life of adults receiving haemodialysis for health professionals.

Common Sleep Disorders in Patients With Chronic Kidney Disease: A Systematic Review on What They Are and How We Should Treat Them

Chronic kidney disease (CKD) causes various complications that significantly impact a patient's overall well-being and quality of life. Sleep disorders are a particularly common issue, especially in patients with advanced disease. This systematic review aims to explore the distinguishing features, prevalence rates, underlying causes, and associated factors related to the most frequent sleep disorders in these patients and present the latest treatment methods for them. It also investigates the link between CKD and sleep disorders and presents the results of the most common sleep disorders found in patients with CKD. Four major sleep disorders have been identified: sleep apnea, restless leg syndrome, excessive drowsiness, and insomnia. These sleep disorders have been discovered to be highly common in CKD patients and have a major influence on their quality of life and morbidity.

Combined aerobic and resistance exercise in maintenance hemodialysis patients: A meta-analysis

Exercise brings many benefits to patients undergoing maintenance hemodialysis (MHD), but the effect of combined aerobic and resistance exercise remains unclear. English and Chinese databases (PubMed, Cochrane Library, Embase, Web of Science, CNKI, VIP, Wan Fang, and CBM) were searched from inception to January 2023 to retrieve qualified randomized controlled trials. The literature selection, data extraction, and risk of bias assessment of included studies were conducted independently by two reviewers. Meta-analysis was performed using RevMan 5.3 software. A total of 23 studies with 1214 participants were included, and 17 of the interventions were conducted during dialysis. Results showed that combined aerobic and resistance exercise (CARE) improved the peak oxygen uptake, six-minute walking test, 60 s sit-to-stand test (STS), 30 s STS, dialysis adequacy, five (out of eight) domains and physical component summary of health-related quality of life (HRQOL) measured by the Medical Outcomes Study Short Form-36, blood pressure, and hemoglobin for MHD patients compared with usual care. No significant changes were found in the mental component summary of HRQOL, C-reactive protein, creatinine, potassium, sodium, calcium, and phosphate. Subgroup analysis showed that intradialytic CARE ameliorated more outcomes, except for handgrip strength and hemoglobin, than non-intradialytic ones. CARE is an effective way to improve physical function, aerobic capacity, dialysis adequacy, and HRQOL for MHD patients. Strategies should be implemented by clinicians and policymakers to motivate patients to do more exercise. Well-designed clinical trials are warranted to explore the effectiveness of non-intradialytic CARE.

The effect of progressive muscle relaxation exercise on the intensity of symptoms and quality of sleep and quality of life in pregnant women with restless leg syndrome

OBJECTIVE

This study, accordingly, was conducted with the purpose of investigating the effect of progressive muscle relaxation exercise on the intensity of restless leg syndrome (RLS) and RLS-related quality of life and sleep in pregnant women with RLS.

METHODS

This one-centered, parallel randomized controlled study was conducted with 52 pregnant women. 27-28th of pregnancy, progressive muscle relaxation exercises training was shown and they were asked to practice them 3 times a week for 8 weeks.

RESULTS

It was found that the RLS Intensity Scale and PSQI posttest mean scores of the women in experiment group are lower on a statically significant level than the mean scores of the women in control group (p = 0.000 and p = 0.001). It was detected that the RLS-Qol posttest mean scores of the women in the experiment group are higher than the mean scores in the control group on a statistically significant level (p = 0.000).

CONCLUSIONS

It was seen that progressive muscle relaxation exercises alleviate RLS intensity and symptoms and improve RLS-related quality of life and sleep in pregnant women.

PRACTICE IMPLICATION

Progressive muscle relaxation exercises are beneficial for pregnant women and can be easily integrated into practice.

The effectiveness of intradialytic exercise in ameliorating fatigue symptoms in patients with chronic kidney failure undergoing hemodialysis: A systematic literature review and meta-analysis

Objective

Hemodialysis in patients with chronic kidney failure is an intervention serving as an alternative to kidney transplantation. In 2019, chronic kidney failure became the world's 6th leading cause of death. In Indonesia, kidney failure has an increasing number of cases every year and is the 10th highest cause of death. According to basic health research in 2018, the prevalence of chronic kidney failure was 3.4%, and 19.3% of patients 15 years of age and older underwent hemodialysis. This study analyzed the effectiveness of intradialytic exercise in ameliorating fatigue symptoms in patients with chronic kidney failure undergoing hemodialysis, in terms of exercise type, duration, time, and frequency.

Methods

All appropriate and eligible full-text articles published between January 2010 and October 2021 were screened and extracted from the databases PubMed, Scopus, ProQuest, Science Direct, CrossRef, Google Scholar, and Garuda Database for Research and Technology. The articles were critically reviewed, and two independent authors reviewed the risk of bias by using the JBI form. Data analysis was performed qualitatively to obtain an overview of the characteristics of intradialytic exercise and quantitatively through meta-analysis.

Results

Intradialytic exercise was found to effectively decrease fatigue by 81% in the intervention group. The most significant effect sizes were as follows: type of intradialytic exercise: aerobic exercise (146%); duration of intradialytic exercise: >20 min (100%); time of intradialytic exercise: first 2 h (127%); and exercise frequency: <12 sessions (120%).

Conclusion

The characteristics of intradialytic exercise that are considered effective in ameliorating fatigue are aerobic exercise lasting >20 min and performed in the first 2 h of hemodialysis, with a frequency of <12 sessions.

Effect of exercise interventions for sleep quality in patients with chronic kidney disease: a systematic review and meta-analysis

INTRODUCTION

Sleep disorder is a common and unpleasant symptom in patients with chronic kidney disease (CKD), bringing a heavy burden on the patients and families. As a non-pharmacological therapy, exercise interventions are widely recommended for CKD patients. However, whether exercise can improve overall sleep quality in such a population remains ambiguous. The systematic review and meta-analysis aimed to evaluate the effect of exercise interventions on sleep quality in CKD patients.

METHODS

PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched from inception to April 22, 2022. A randomized controlled trial (RCT) added an exercise intervention to conventional treatment/usual care to assess the effect on sleep quality in CKD patients. Two authors independently selected literature, extracted data, assessed the risk of bias using the Cochrane risk of bias tool 2, and assessed the certainty of the evidence using the Grading of Recommendations, Assessment, Development, and Evaluation. The outcome was analyzed using a random-effect model using the Hartung-Knapp-Sidik-Jonkman method as a standardized mean difference (SMD). Additional statistical analysis includes the Egger regression test, subgroup analysis, sensitivity analysis, and meta-regression.

RESULTS

Nineteen articles (20 RCTs) enrolling 989 patients with CKD were included. The pooled SMD suggested favorably associated exercise interventions (SMD - 0.16; 95% CI - 0.62 to 0.31; very low evidence) with substantial heterogeneity (I² = 87%). Subgroup analyses demonstrated that SMD for sleep quality favored moderate intensity and aerobic exercise, no matter the time, but not statistically significant. Meta-regression showed that the effect size of exercise interventions on sleep quality was not associated with the total sample size, the proportion of males, duration of intervention, mean age, and exercise volume but was associated with baseline sleep scores. In addition, there may be an exercise threshold for the effect of exercise on sleep in CKD patients (i.e., 80 min/week).

CONCLUSION

This systematic review and meta-analysis suggest that exercise interventions may be associated with improved sleep quality in patients with CKD. However, high heterogeneity and a small effect size limit this result. More studies and standardized reporting of exercise intervention characteristics should be conducted in the future to strengthen the most convincing evidence in this field.

Therapeutic effects of exercise interventions for patients with chronic kidney disease: an umbrella review of systematic reviews and meta-analyses

OBJECTIVE

To conduct an overview of meta-analyses evaluating the impact of exercise interventions on improving health outcomes in patients with chronic kidney disease (CKD).

DESIGN

An umbrella review of systematic review and meta-analyses of intervention trials was performed.

DATA SOURCES

PubMed, Web of Science, Embase and the Cochrane Database of Systematic Reviews were searched from inception to 9 March 2021 for relevant articles.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Eligible meta-analyses compared the effects of usual care with and without exercise in patients with CKD. Health outcomes included those related to cardiovascular risk factors, physical fitness, dialysis-related symptoms, dialysis adequacy and health-related quality of life. Systematic reviews and meta-analyses that included fewer than 3 RCTs or fewer than 100 participants were excluded from the analysis.

RESULTS

A total of 31 eligible systematic reviews and meta-analyses were included that assessed 120 outcomes. For physical fitness, there was a moderate effect size for cardiorespiratory fitness, muscle strength and body composition and small effect size for muscle endurance. The effect sizes for cardiovascular risk factors, dialysis-related symptoms and health-related quality of life outcomes were small. According to the Grading of Recommendations Assessment, Development and Evaluation framework, most outcomes were low or very low quality.

CONCLUSION

Exercise appears to be a safe way to affect concomitant cardiovascular risk factors, such as blood pressure, improve physical fitness and health-related quality of life and reduce dialysis-related symptoms in patients with CKD.

Smartphone-based home workout program for shift-work nurses working during the COVID-19 pandemic

This study aimed to develop a smartphone-based home workout program for shift-work nurses to increase their levels of exercise and examine its effects on health (sleep disturbance, fatigue, musculoskeletal problems, and resilience) and nursing performance. For this quasi-experimental study with a nonequivalent control group, 54 shift-work nurses were recruited from two general wards at a hospital in Korea and assigned to the intervention and control groups. Nurses in the intervention group were encouraged to exercise regularly using the home workout application for 18 weeks. For the first 12 weeks, text-message counseling and environmental improvement were carried out; only environmental improvement was implemented in the remaining 12-18 weeks. The control group did not receive any intervention. After excluding dropouts, the data of the final 25 participants in the intervention group and 24 participants in the control group were analyzed. Compared with the control group, the intervention group showed statistically significant improvements in physical and psychological health. Hospital organizations could adopt a smartphone-based home workout program to overcome obstacles to exercise, which could lead to positive health outcomes for shift-work nurses.

Acupressure reduces the severity of restless legs syndrome in hemodialysis patients: A cluster-randomized crossover pilot study

Background

Restless legs syndrome (RLS), a neurological disorder, often affects sleep quality in hemodialysis patients. This study aimed to evaluate acupressure's effect on the severity of RLS symptoms and sleep quality in hemodialysis patients with RLS.

Methods

This study is a cluster-randomized crossover pilot study. Patients were randomized to two sequences: acupressure for one month and observation for another month (AC); and observation for one month and acupressure for another month (CA). For the four-week acupressure intervention, patients received 36 min of acupressure three times weekly during their hemodialysis sessions. The acupoints were on the bilateral lower limbs, including Zusanli (ST36), Yanglingquan (GB34), Sanyinjiao (SP6), Xuanzhong (GB39), Chengshan (BL57), and Taichong (LR3). RLS severity and sleep quality (measured with the Pittsburgh sleep quality index, PSQI) were measured at baseline, month 1, and month 2.

Results

AC sequence (n = 14) was similar to the CA sequence (n = 9) in terms of gender, age, education, employment, marital status, comorbid disease, BMI, duration of dialysis, medication for RLS and insomnia, RLS severity, and PSQI. The general linear mixed model revealed no significant carryover effect on RLS severity, PSQI, and the seven subscales of PSQI. A significant treatment effect (acupressure) was only observed in RLS severity (p = 0.0013) but not in PSQI and the seven subscales. The significant period effect was observed in RLS severity (p = 0.0250) and the subscale of sleep disturbance (p = 0.0021).

Conclusion

In hemodialysis patients with RLS, acupressure can alleviate the severity of RLS but cannot improve sleep quality.

Comparison of the Effect of Reflexology and Swedish Massage on Restless Legs Syndrome and Sleep Quality in Patients Undergoing Hemodialysis: a Randomized Clinical Trial

Background

Patients undergoing hemodialysis experience painful complications such as restless leg syndrome and poor sleep quality, which negatively affect their quality of life.

Purpose

This study aimed to compare the effect of reflexology and Swedish massage on restless leg syndrome and sleep quality in patients undergoing hemodialysis.

Method

This is a randomized clinical trial conducted on 90 patients undergoing hemodialysis. The two intervention groups received either foot reflexology (n = 30) or Swedish massage (n = 30) for four weeks. In the sham group (n = 30), a simple touch of the knee down was performed with the same conditions as the intervention groups. Each sample completed the International Restless Leg Syndrome and Pittsburgh Sleep Quality Index Questionnaires before, immediately after, and one month after the intervention.

Result

The results showed that immediately after the intervention, restless leg syndrome and sleep quality were significantly better in the foot reflexology massage group than the Swedish massage and sham groups (PRLS < 0.001, PPSQI < 0.001); also, changes in restless leg syndrome and sleep quality, respectively, before and one-month follow-up after the intervention were not significant in all three groups (PRLS = 0.47, PPSQI = 0.95), (PRLS = 0.91, PPSQI = 0.87).

Conclusion

Reflexology and Swedish massage, as complementary methods, can improve the restless leg syndrome and sleep quality of patients undergoing hemodialysis. However, foot reflexology massage had been more effective.

Effect of intradialytic exercise on geriatric issues in older patients undergoing hemodialysis: a single-center non-randomized controlled study

PURPOSE

This study investigated the effect of 1 year of intradialytic exercise on older hemodialysis patients with geriatric issues.

METHODS

Forty-six patients aged ≥ 70 years were non-randomly assigned to two groups (exercise group: 27, control group: 19). Intradialytic exercise consisted of 30 min of aerobic exercise using a cycle ergometer, and resistance training comprising four exercises using an elastic tube three times per week for 1 year. Handgrip strength, leg extremity muscle strength, 10-m walk speed, short physical performance battery, serum albumin, Geriatric Nutritional Risk Index (GNRI), geriatric depression scale, frailty, and mobility were each assessed before and after the intervention.

RESULTS

The control group exhibited a significant reduction in handgrip strength, 10-m walking speed, serum albumin, and GNRI after intervention compared to baseline (p < 0.05). Conversely, no significant reductions were observed in the exercise group. The ΔGNRI (effect size, 0.69; 95% confidence interval [CI]  - 5.21, - 0.1; p < 0.05) and Δserum albumin (effect size, 0.72; 95% CI - 0.31, - 0.02; p < 0.05) before and after the intervention declined significantly less in the exercise group than in the control group. Other between-group values were not significantly different. The number of frail patients and patients requiring walking assistance exhibited no significant intra-group or between-group differences before and after the intervention.

CONCLUSION

Intradialytic exercise prevented the worsening of nutritional status and physical function in the exercise group compared to the control group. Exercise therapy during dialysis is an important aspect of patient care that helps prevent functional decline in older patients.

Correlation between Physical Activity and Psychological Distress in Patients Receiving Hemodialysis with Comorbidities: A Cross-Sectional Study

Comorbidities cause psychological distress to patients on hemodialysis and cause their physical function to deteriorate. This study aims to examine whether physical patterns are associated with anxiety, depression and fatigue among patients with and without comorbidities who are on hemodialysis. To this end, a cross-sectional survey was administered to 120 patients on hemodialysis. Data were collected using the International Physical Activity Questionnaire—Short Form, Beck Depression Inventory—Second Edition, Beck Anxiety Inventory, and Brief Fatigue Inventory—Taiwan Version. An independent sample t test and generalized linear model analyses were conducted. The results revealed that patients with comorbidities exhibited more severe levels of depression (p < 0.001), anxiety (p < 0.001), and fatigue (p = 0.010) than patients without comorbidities. Additionally, patients on hemodialysis with a high physical activity level (≥600 metabolic equivalent of task per min/week) exhibited less depression (B = −4.03; p < 0.001; 95% confidence interval [CI] = −6.04, −2.03) and anxiety (B = −2.64; p = 0.002; 95% CI = −4.27, −1.00) severity than those with a low physical activity level; those who engaged in weekly physical activities exhibited less fatigue severity (B = −1.17; p = 0.001; 95% CI = −1.84, −0.49) and fatigue interference (B = −0.61; p = 0.015; 95% CI = −1.10, −0.12). For patients on hemodialysis, having comorbidities was correlated with more severe levels of depression, anxiety, and fatigue. Weekly moderate-intensity physical activities were revealed to be correlated with less severity levels of depression, anxiety, and fatigue. The study findings aid the development of interventions for promoting physical activity among patients on hemodialysis to prevent the exacerbation of complications caused by comorbidities and psychological distress.

Exercise training for adults undergoing maintenance dialysis

BACKGROUND

Dialysis treatments weigh heavily on patients' physical and psychosocial health. Multiple studies have assessed the potential for exercise training to improve outcomes in adults undergoing dialysis. However, uncertainties exist in its relevance and sustainable benefits for patient-important outcomes. This is an update of a review first published in 2011.

OBJECTIVES

To assess the benefits and safety of regular structured exercise training in adults undergoing dialysis on patient-important outcomes including death, cardiovascular events, fatigue, functional capacity, pain, and depression. We also aimed to define the optimal prescription of exercise in adults undergoing dialysis.

SEARCH METHODS

In this update, we conducted a systematic search of the Cochrane Kidney and Transplant Register of Studies up to 23 December 2020. The Register includes studies identified from CENTRAL, MEDLINE, EMBASE, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov as well as kidney-related journals and the proceedings of major kidney conferences.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs of any structured exercise programs of eight weeks or more in adults undergoing maintenance dialysis compared to no exercise or sham exercise.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the search results for eligibility, extracted the data and assessed the risk of bias using the Cochrane risk of bias tool. Whenever appropriate, we performed random-effects meta-analyses of the mean difference in outcomes. The primary outcomes were death (any cause), cardiovascular events and fatigue. Secondary outcomes were health-related quality of life (HRQoL), depression, pain, functional capacity, blood pressure, adherence to the exercise program, and intervention-related adverse events.

MAIN RESULTS

We identified 89 studies involving 4291 randomised participants, of which 77 studies (3846 participants) contributed to the meta-analyses. Seven studies included adults undergoing peritoneal dialysis. Fifty-six studies reported aerobic exercise interventions, 21 resistance exercise interventions and 19 combined aerobic and resistance training within the same study arm. The interventions lasted from eight weeks to two years and most often took place thrice weekly during dialysis treatments. A single study reported death and no study reported long-term cardiovascular events. Five studies directly assessed fatigue, 46 reported HRQoL and 16 reported fatigue or pain through their assessment of HRQoL. Thirty-five studies assessed functional capacity, and 21 reported resting peripheral blood pressure. Twelve studies reported adherence to exercise sessions, and nine reported exercise-related adverse events. Overall, the quality of the included studies was low and blinding of the participants was generally not feasible due to the nature of the intervention. Exercise had uncertain effects on death, cardiovascular events, and the mental component of HRQoL due to the very low certainty of evidence. Compared with sham or no exercise, exercise training for two to 12 months may improve fatigue in adults undergoing dialysis, however, a meta-analysis could not be conducted. Any exercise training for two to 12 months may improve the physical component of HRQoL (17 studies, 656 participants: MD 4.12, 95% CI 1.88 to 6.37 points on 100 points-scale; I² = 49%; low certainty evidence). Any exercise training for two to 12 months probably improves depressive symptoms (10 studies, 441 participants: SMD -0.65, 95% CI -1.07 to -0.22; I² = 77%; moderate certainty evidence) and the magnitude of the effect may be greater when maintaining the exercise beyond four months (6 studies, 311 participants: SMD -0.30, 95% CI 0.14 to -0.74; I² = 71%). Any exercise training for three to 12 months may improve pain (15 studies, 872 participants: MD 5.28 95% CI -0.12 to 10.69 points on 100 points-scale; I² = 63%: low certainty evidence) however, the 95% CI indicates that exercise training may make little or no difference in the level of pain. Any exercise training for two to six months probably improves functional capacity as it increased the distance reached during six minutes of walking (19 studies, 827 participants: MD 49.91 metres, 95% CI 37.22 to 62.59; I² = 34%; moderate certainty evidence) and the number of sit-to-stand cycles performed in 30 seconds (MD 2.33 cycles, 95% CI 1.71 to 2.96; moderate certainty evidence). There was insufficient evidence to assess the safety of exercise training for adults undergoing maintenance dialysis. The results were similar for aerobic exercise, resistance exercise, and a combination of both aerobic and resistance exercise.

AUTHORS' CONCLUSIONS

It is uncertain whether exercise training improves death, cardiovascular events, or the mental component of HRQoL in adults undergoing maintenance dialysis. Exercise training probably improves depressive symptoms, particularly when the intervention is maintained beyond four months. Exercise training is also likely to improve functional capacity. Low certainty evidence suggested that exercise training may improve fatigue, the physical component of quality of life, and pain. The safety of exercise training for adults undergoing dialysis remains uncertain.

The effect of acupoint therapy on sleep quality of hemodialysis patients: A protocol for systematic review and meta-analysis

BACKGROUND

Hemodialysis patients usually have sleep disturbance at varying degrees, which seriously affects the therapeutic efficacy and quality of life. Therefore, improving the sleep quality of hemodialysis patients is the key during treatment. Acupoint therapy can improve the sleep quality of patients. However, guidelines for improving sleep quality of hemodialysis patients by acupoint therapy are scant. This study aims to evaluate the effect of acupoint therapy on sleep quality in hemodialysis patients through a meta-analysis, providing clinical evidences.

METHODS

Randomized controlled trials (RCTs) reporting the effect of acupoint therapy on sleep quality in hemodialysis patients published before November 2021 will be searched in the China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Wanfang database, the Chinese Scientific Journal Database, PubMed, Embase, The Cochrane Library, and Web of Science databases. Eligible literatures will be screened according to inclusion and exclusion criteria and assessed for quality using the Cochrane Risk of Bias Assessment Tool. Meta-analysis will be performed using Revman 5.4 software.

RESULTS

This study will evaluate the effect of acupoint therapy on sleep quality in hemodialysis patients using the Pittsburgh Sleep Quality Index (PSQI).

CONCLUSION

This study will provide a reliable evidence-based basis for conducting acupoint therapy to improve sleep quality in hemodialysis patients.

Effect of massage therapy with lavender oil on severity of restless legs syndrome and quality of life in hemodialysis patients

PURPOSE

This study assessed the effects of massage therapy using 5% lavender oil on the severity of restless legs syndrome (RLS) and the quality of life (QoL) of patients on hemodialysis (HD).

DESIGN AND METHODS

This is a randomized placebo-controlled study with a pretest-posttest design. This study was conducted from January 30, 2019, to May 6, 2019, at HD centers in Turkey, and it includes 58 participants-31 study patients and 27 controls. Data were collected using patient identification form, RLS severity rating scale, Kidney Disease Quality of Life Scale (KDQOL^TM -36) and patient follow-up charts. As per the massage therapy protocol, the patients in the study and control groups received massage therapy with lavender oil and baby oil, respectively.

FINDINGS

RLS severity significantly decreased in all follow-up weeks in the study group and in the first, second, and third follow-up weeks in the control group. There were significant differences between the groups in terms of KDQOL^TM -36 subscales and total scores at the initial and final follow-ups.

CONCLUSION

In HD patients, massage with lavender oil lessened the severity of RLS and improved the QoL. Accordingly, this therapy can be recommended to HD patients.

CLINICAL RELEVANCE

Massage therapy during HD sessions is easy, inexpensive, and patient-friendly with no side effects. It is known to reduce symptoms and enable the patients to easily perform daily activities of living. Massage therapy with lavender oil is effective and can be easily applied to patients with RLS by nurses.

TRIAL REGISTRATION

This study was registered under the Clinical Trials protocol registration system (NCT04630470) upon completion.

Motivation, Barriers, and Suggestions for Intradialytic Exercise-A Qualitative Study among Patients and Nurses

Background: Intradialytic exercise is an effective intervention to reduce morbidity and mortality and increase quality of life among patients with chronic kidney disease undergoing dialysis. However, implementing and sustaining it in clinical practice has proved challenging. To identify how to best design an effective and sustainable intervention in clinical practice, we aimed to explore hemodialysis patients’ and nurses’ attitudes towards intradialytic exercise, including their motivation, anticipated barriers, and suggestions for the design of a proposed exercise program. Methods: Data were collected through qualitative semistructured interviews with patients and focus group interviews with nurses and analyzed inductively with content analysis. Results: Overall, patients’ and nurses’ attitudes towards intradialytic exercise were positive. Patients were motivated by their expectations about perceived benefits, such as improved quality of life and reduced musculoskeletal pain. Their main concern was triggering dialysis machine alarms and disturbing nurses. Nurses were more skeptical of intradialytic exercise and concerned about patient safety. Patients and nurses had several ideas on how to design a safe and motivating intradialytic exercise intervention. Conclusion: The analysis of patients’ and nurses’ experiences and attitudes generated recommendations for an intradialytic exercise program. Recommendations include individually tailored programs that are safe and that patients can do independently, continuous collaboration between patients, nurses, physicians, and physiotherapists, and educating nurses about the benefits and safety of intradialytic exercise.

Pharmacological and Nonpharmacological Treatments for Restless Legs Syndrome in End Stage Kidney Disease: A Systematic Review and Component Network Meta-Analysis

BACKGROUND

Restless legs syndrome (RLS) is common among patients with end stage kidney disease (ESKD) and is associated with poor outcomes. Several recently published studies had focused on pharmacological and nonpharmacological treatments of RLS, but an updated meta-analysis has not been conducted.

METHODS

The study population was adult ESKD patients on dialysis with RLS. Randomized controlled trials were selected. The primary outcome was reduction in RLS severity. The secondary outcomes were improvement in sleep quality and treatment-related adverse events. Frequentist standard network meta-analysis and additive component network meta-analysis was performed. The evidence certainty was assessed using Confidence in NMA (CINeMA) framework.

RESULTS

A total of 24 RCTs with 1,252 participants were enrolled and 14 interventions were compared. Cool dialysate produced the largest RLS severity score reduction (MD: 16.82, 95% CI: 10.635-23.02) and high level of confidence. Other potential non-pharmacologic interventions including intradialytic stretching exercise (MD: 12.00, 95% CI: 7.04-16.97) and aromatherapy massage (MD: 10.91, 95% CI: 6.96-14.85) but all with limited confidence of evidence. Among the pharmacological interventions, gabapentin was the most effective (MD: 8.95, 95% CI: 1.95-15.85), which also improved sleep quality (SMD: 2.00, 95% CI: 0.47-3.53). No statically significant adverse events were detected.

CONCLUSIONS

The NMA supports that cool dialysate is appropriate to apply to treat patients with ESKD and RLS. Gabapentin is most effective pharmacologic intervention which also might improve sleep quality. Further parallel RCTs with sufficient sample sizes are required to evaluate these potential interventions and long-term effects.

Development and Psychometric Evaluation of "Caregiver Burden Questionnaire for Family Caregivers of Patients Undergoing Hemodialysis": A Protocol for A Sequential Exploratory Mixed-Method Study

Objective: Caregiver burden is defined as the physical, financial, mental, and social problems stemmed from providing care for one of the family members who is involved with a medical problem. The precise measurement of caregiver burden is crucial, and it is essential to have an appropriate and specific tool for measuring caregiver burden. This study will be carried out using sequential exploratory mixed-method design with the aim of development and psychometric evaluation of a questionnaire for caregiver burden in family caregivers of hemodialysis patients. Method : The study will be done in 2 phases: 1. qualitative study and literature review, and 2. designing and psychometric evaluation of the questionnaire. In the qualitative phase, family caregivers of hemodialysis patients, patients, nurses, physicians, and social workers will be selected using the maximum variation purposive sampling method. Data will be gathered through semi-structured interviews using a combination of the questions derived from the model and open-ended questions and will be analyzed using directed content analysis. The literature review will be carried out based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses to improve the reporting of the systematic review. After developing the primary item pool, in the quantitative phase, the psychometric properties of the questionnaire will be evaluated. In this regard, face, content, and construct validity (exploratory factor analysis), internal consistency (Alpha's Cronbach), reliability (test-retest), responsiveness, interpretability, and feasibility of the questionnaire will be assessed. Results: The primary questionnaire will be developed based on the qualitative and systematic literature review; then, its psychometric properties will be assessed in the second phase. The result section will consist of the findings of these two phases. Conclusion: It seems that a specific questionnaire could be a facilitator of identifying and measuring the actual caregiver burden.

A Systematic Review of Potentially Effective Nonpharmacological Interventions for Reducing Fatigue among Iranian Patients Who Receive Hemodialysis

BACKGROUND AND PURPOSE

Fatigue control in hemodialysis (HD) patients requires a multidisciplinary approach. This study aimed to comprehensively review the available research literature regarding the nonpharmacological interventions used for reducing fatigue among Iranian HD patients.

METHODS

In this systematic review, an extensive search of the literature was conducted on PubMed, Web of Science, and Scopus databases, using the keywords related to the purpose. Also, the Persian equivalent of these keywords was searched in Iranian databases, such as Iranmedex and Scientific Information Database (SID) from the inception to June 16, 2020.

RESULTS

Of 2,761 articles, 25 studies were included in the review. Among a total of 1,748 Iranian HD patients with a mean age of 54.17 (SD = 12.27) years, 61.38% were male. Interventions such as educational-based programs (n = 5), nutrition-based programs (n = 2), massage therapy (n = 3), exercise-based programs (n = 4), relaxation technique (n = 3), combination of relaxation technique and inhalation aromatherapy (n = 1), energy therapy (reflexology and acupressure) (n = 3), and mind-guided imagery (n = 1) were effective in reducing fatigue in Iranian HD patients.

DISCUSSION/CONCLUSION

These simple, low-cost, and practical interventions can be used for the reduction of fatigue among HD patients by nurses. However, future well-designed studies are recommended to confirm the efficacy of these and other potentially effective interventions for reducing fatigue in HD patients.

Quasi-cluster randomized trial of a six-month low-intensity group-based resistance exercise for hemodialysis patients on depression and cognitive function: a 12-month follow-up

Objective

This study aimed to examine the effects of a six-month group-based low-intensity resistance exercise program on depression and the cognitive function of hemodialysis patients.

Method

We conducted a quasi-cluster randomized, open-label controlled study from October 2017 to December 2018. Forty-two patients undergoing hemodialysis completed the trial over six months; half participated in the resistance exercise group (n = 21, mean = 74.90 years of age, SD = 2.23, 66.67% female) and the other half were in a stretching control group (n = 21, mean = 72.57 years of age, SD = 2.26, 28.57% female). Depressive symptoms and cognitive function were the primary outcome measures. Behavioral and psychological problems associated with cognitive decline (NPI-Q), subjective insomnia, and exercise self-efficacy were secondary outcomes. Outcomes were measured at baseline, three-month (mid-intervention), six-month (end of intervention), and 12-month (six months after intervention) follow-ups. Linear mixed model analyses were used to determine short-term (immediately after intervention) and long-term (six months after intervention) effects.

Results

In depression, cognitive function, and the NPI-Q, there were no significant effects. In subjective insomnia, a short-term group-by-time interaction in the intervention group compared to the control group was found (ES = .43). However, the effect had disappeared by the 12-month follow-up. In exercise self-efficacy, short- and long-term group-by-time interactions were found. A significant short-term increase in the resistance exercise and a significant decrease in the stretching control was observed (ES = -.83). However, the effect was weakened in the long term (ES = -.38).

Conclusion

The results showed that low-intensity group resistance exercise would reduce subjective insomnia and improve exercise self-efficacy, but the effect was not maintained by six months after the program.

Trial registration: This study was registered on the University Hospital Medical Information Network Clinical Trials Registry (UMIN000029372).

Effects of Intradialytic Exercise on Dialytic Parameters, Health-Related Quality of Life, and Depression Status in Hemodialysis Patients: A Randomized Controlled Trial

Exercise is fundamentally important in managing chronic diseases and improving health-related quality of life (HRQL). However, whether intradialytic exercise is safe through assessment of changes in dialytic parameters and has a positive impact on HRQL and depression status of hemodialysis patients requires further research with diverse racial and cultural populations to identify. This study aimed to evaluate the effects of intradialytic exercise on dialytic parameters, HRQL, and depression status in hemodialysis patients. A randomized controlled trial was conducted at a medical center in Northern Taiwan. Sixty-four hemodialysis patients were recruited using stratified random sampling. Participants were randomized into an experimental group (EG, n = 32) or a control group (CG, n = 32). The EG received a 12-week intradialytic exercise program while the CG maintained their usual lifestyles. Dialytic parameters, HRQL, and depression status were collected at baseline and at 12 weeks. The results indicated no differences in the dialytic parameters from the baseline between both groups. However, the EG had increased HRQL (ß = 22.6, p < 0.001) and reduced depression status (ß = −7.5, p = 0.02) at 12 weeks compared to the CG. Therefore, a 12-week intradialytic exercise regime is safe and effective in improving HRQL and reducing depression status for hemodialysis patients.

Effects of nonpharmacological intervention on sleep quality in hemodialysis patients: A protocol for systematic review and meta-analysis

BACKGROUND

Nonpharmacological intervention can improve the sleep quality of hemodialysis patients. However, there are many types of nonpharmacological interventions, which makes it difficult to determine the best one. Therefore, this study carried out network meta-analysis to evaluate the effects of nonpharmacological intervention on sleep quality of hemodialysis patients, so as to provide evidence for the selection of the optimal nonpharmacological intervention for the improvement of sleep quality of hemodialysis patients clinically.

METHODS

Randomized controlled trials on the effects of nonpharmaceutical interventions on sleep quality in hemodialysis patients were conducted by searching English databases (PubMed, Cochrane Library, EMBASE, and Web of Science) and Chinese databases (Chinese Scientific Journal Database, China National Knowledge Infrastructure Database, Wanfang, and China Biomedical Literature Database) on computer. The retrieval time was from the establishment of the database to May 2021. Literature screening, data extraction, and evaluation of the risk of bias in the included studies were conducted independently by two researchers. Data analysis was performed with STATA14.0 and GEMTC 0.14.3 software.

RESULTS

We will disseminate the findings of this systematic review and meta-analysis via publications in peer-reviewed journals.

CONCLUSIONS

This study will provide the best evidence-based evidence to support the effects of non-pharmacological interventions on sleep quality in hemodialysis patients.

ETHICS AND DISSEMINATION

Ethical approval was not required for this study. The systematic review will be published in a peer-reviewed journal, presented at conferences, and shared on social media platforms. This review would be disseminated in a peer-reviewed journal or conference presentations.

Efficacy of Qigong Exercise for Treatment of Fatigue: A Systematic Review and Meta-Analysis

Objective: Several studies suggested that Qigong exercise (QE) can relieve fatigue in patients diagnosed with various diseases. Our review aimed to evaluate the efficacy of QE for alleviating fatigue. Methods: A related literature search was performed in the PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and VIP data bases from inception to November 2020. Information on fatigue, malaise, tiredness, and Qigong research data was collected. Results: Sixteen randomized controlled trials (RCTs) were reported in patients with cancer (n = 4), chronic fatigue syndrome (n = 2), and other diseases (n = 10). The QE groups showed significant improvements in total fatigue intensity [15 RCTs, p < 0.00001; standard mean difference (SMD) -0.69 (-0.95 to -0.44)]. The QE groups did not show significant improvement in quality of life [4 RCTs, p = 0.08; SMD 0.53 (-0.07 to 1.14)]. The statistically significant difference of the subgroup analyses (different primary diseases, QE types, and study quality) also remained unchanged. Conclusion: The findings of this meta-analysis indicate that QE may be beneficial for improving fatigue in patients diagnosed with various diseases. Considering the limitations of the study, we draw a very cautious conclusion regarding the resulting estimate of the effect. Further studies are warranted to better understand the benefits of QE in primary medical care.

Can passive pedaling improve sexual function in patients under hemodialysis? A randomized clinical trial

To investigate the effect of passive pedaling with mini bike on sexual function in patients under hemodialysis. This study was a randomized clinical trial. Thirty-seven patients undergoing hemodialysis were assigned to the intervention (n = 20) and control (n = 17) groups by the stratified block randomization method. The intervention group exercised with a mini bike that was automatic and tuned for patients during the first 2 h of dialysis, twice a week for 20 min each time, for 3 months. The International Index of Erectile Function and Female Sexual Function Index were used to assess the sexual function in the first, second, and third months during the intervention and one month after the intervention. A higher score indicates a better sexual function. Repeated measure ANOVA, Chi-square and Fisher exact tests, independent t, and Mann-Whitney U tests were used for data analysis. The SPSS software version 22 was used for data analysis. Sexual function scores of the intervention group were 35.9 at the beginning of the study, 34.1 in the first month, 37.4 in the second month, 34.8 in the third month, and 31.7 one month after the study. There was no significant difference in the scores of sexual function in the intervention group during the study. The mean scores of sexual function in the control group were 34.5, 34.4, 34.9, 33.8, and 33.9 at the beginning of the study, in the first month, in the second month, in the third month, and one month after the study, respectively (p > 0.05). There was no significant difference between the two groups in terms of sexual function scores during and after the intervention (p > 0.05). Passive pedaling with mini-bike had no effect on sexual function of hemodialysis patients.

Effect of Aerobic Exercise on Dialysis-Related Symptoms in Individuals Undergoing Maintenance Hemodialysis: A Systematic Review and Meta-Analysis of Clinical Trials

BACKGROUND

Hemodialysis is associated with a high symptom burden that impairs health-related quality of life and functional status. Effective symptom management is a priority for individuals receiving hemodialysis. Aerobic exercise may be an effective, nonpharmacologic treatment for specific hemodialysis-related symptoms. This systematic review investigated the effect of aerobic exercise on hemodialysis-related symptoms in adults with kidney failure undergoing maintenance hemodialysis.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We searched MEDLINE, PubMed, Cochrane CENTRAL, CINAHL, PsycINFO, SPORTDiscus, EMBASE, PEDro, and Scopus databases from 1960 or inception until April 15, 2020 for randomized controlled trials investigating the effect of aerobic exercise on hemodialysis-related symptoms, identified as prespecified primary or secondary outcomes, as compared with controls in adults on maintenance hemodialysis. We identified restless legs syndrome as the primary outcome.

RESULTS

Of 3048 studies identified, 15 randomized controlled trials met the eligibility criteria. These studies investigated the effect of aerobic exercise on restless legs syndrome (two studies), sleep disturbance (four studies), anxiety (four studies), depression (nine studies), muscle cramping (one study), and fatigue (one study). Exercise interventions were intradialytic in ten studies and outside of hemodialysis in five studies. Heterogenous interventions and outcomes and moderate to high risk of bias precluded meta-analysis for most symptoms. Aerobic exercise demonstrated improvement in symptoms of restless legs syndrome, muscle cramping, and fatigue, as compared with nonexercise controls. Meta-analysis of depressive symptoms in studies using the Beck Depression Inventory demonstrated a greater reduction in Beck Depression Inventory score with exercise as compared with control (mean difference -7.57; 95% confidence interval, -8.25 to -6.89).

CONCLUSIONS

Our review suggests that in adults on maintenance hemodialysis, aerobic exercise improves several hemodialysis-related symptoms, including restless legs syndrome, symptoms of depression, muscle cramping, and fatigue. However, the use of validated outcome measures with demonstrated reliability and responsiveness in more diverse hemodialysis populations is required to fully characterize the effect of this intervention.

Effect of Cool Dialysate on Depression in Patients with Chronic Renal Failure Treated with Hemodialysis: A Randomized Clinical Trial

Background: Depression is one of the most common psychiatric problems in hemodialysis patients. Objectives: This study aimed to evaluate the effect of cool dialysate on depression in patients with chronic renal failure treated with hemodialysis. Methods: This randomized clinical trial was performed on 66 hemodialysis patients suffering from depression. Patients were selected by a convenience sampling method and divided equally into intervention and control groups randomly by permuted block allocation, each group containing 33 patients. Data were acquired with the Beck Depression inventory-I. The intervention and control groups underwent one month of treatment with cool dialysate at 35.5 and 37°C, respectively. The severity of depression for each group was measured at the end of each treatment stage and two weeks after the intervention. Data were analyzed using R version 25 software with a confidence level of 95%. Results: There was no statistically significant difference between the control and intervention groups before and after the intervention (P-values more than 0.05). While the mean of depression severity for the control group decreased from 26.15 ± 1.46 to 22.24 ± 2.00 (P-values < 0.01), the mean of depression severity for the intervention group decreased from 25.56 ± 1.28 to 22.41 ± 1.65 by the intervention (P-value > 0.05). Conclusions: The application of cool dialysate as a non-pharmacological method did not significantly reduce the severity of depression in patients undergoing hemodialysis. Therefore, it is advised to perform further studies that include more research units from different geographical locations, considering a longer intervening duration.

Accelerometer-measured physical activity and its impact on sleep quality in patients suffering from restless legs syndrome

BACKGROUND

The primary symptoms of restless legs syndrome (RLS) are sleep onset insomnia and difficulty to maintain sleep. Previous studies have shown that regular physical activity can reduce the risk of developing RLS. However, the relationship between physical activity and sleep quality parameters in individuals suffering from RLS has not yet been investigated by applying accelerometry. Thus, the present study investigates the impact of physical activity (measuring both intensity levels and duration of physical activity) during the day (7-12 h, 12-18 h, 18-23 h) on sleep quality in patients suffering from idiopathic RLS by applying a real-time approach.

METHODS

In a sample of 47 participants suffering from idiopathic RLS, physical activity and sleep quality were measured over one week using accelerometers. For data analysis, physical activity levels and step counts during three periods of the day (morning, afternoon, evening) were correlated with sleep quality parameters of the subsequent night.

RESULTS

This observational study revealed that in most instances physical activity was not correlated with sleep parameters (two exceptions exist: steps taken in the morning were negatively correlated with periodic leg movements during sleep, and physical activity in the evening was negatively correlated with total sleep time). The physical activity levels of the participants in this study, however, were unexpectedly high compared to population-level data and variance in physical activity was low. The average activity was 13,817 (SD = 4086) steps and 347 (SD = 117) minutes of moderate physical activity per day in females, and 10,636 (SD = 3748) steps and 269 (SD = 69) minutes of moderate physical activity in males, respectively. Participants did not engage in any vigorous physical activity.

CONCLUSIONS

Further interventional studies are needed to investigate the daily effects of different intensities of physical activity on RLS symptoms.

Nonopioid Approaches to Pain Management in Chronic Kidney Disease

Patients with chronic kidney disease (CKD) and end-stage renal disease experience high pain and symptom burden, but management of chronic pain in this population remains challenging. Recent studies have shown a high rate of opioid prescription and use in patients with kidney disease. However, the concern for opioid-related morbidity and mortality suggests a need to reconsider the safety and efficacy of opioid use in patients with CKD. In this review, we describe the current approaches to pain management in CKD, highlight the evolving opioid-related risks and kidney-specific concerns, and offer both pharmacologic and nonpharmacologic nonopioid strategies for pain management in patients with kidney disease, emphasizing the importance of using a multimodal approach to optimize pain control.

Premenopausal Women With a Diagnosis of Endometriosis Have a Significantly Higher Prevalence of a Diagnosis or Symptoms Suggestive of Restless Leg Syndrome: A Prospective Cross-Sectional Questionnaire Study

BACKGROUND

Endometriosis and restless leg syndrome (RLS) are both chronic conditions that can negatively affect a woman's quality of life. A higher prevalence of RLS is seen in women and particularly in those who are pregnant, suggesting a possible ovarian hormonal influence. Endometriosis is a common (affecting 1 in 10 women) estrogen driven gynecological condition, and the prevalence of RLS in women with symptoms or a diagnosis of endometriosis is unknown.

METHODS

A prospective, cross-sectional, observational self-completed questionnaire study was distributed to 650 pre-menopausal women attending the gynecological department at Liverpool Women`s Hospital over a period of 4 months. 584 questionnaires were returned and 465 completed questionnaires were included in the final dataset. Data on RLS-associated (The International Restless Leg Syndrome Study Group rating scale) and endometriosis-associated (modified-British Society of Gynaecological Endoscopists pelvic pain questionnaire) symptoms were collected.

RESULTS

Women who reported a prior surgical diagnosis of endometriosis had a greater risk of having a prior formal diagnosis of RLS (OR 4.82, 95% CI 1.66,14.02) and suffering RLS symptoms (OR 2.13, 95% CI 1.34-3.39) compared with those without a diagnosis. When women with either a formal surgical diagnosis or symptoms associated with endometriosis were grouped together, they also have a significantly increased risk of having either a formal diagnosis or symptoms suggestive of RLS (OR 2.49, 95% CI 1.30, 3.64). In women suffering with endometriosis-associated symptoms, the cumulative endometriosis-associated symptom scores demonstrated a modest positive correlation with RLS severity scores (r=0.42 95% CI 0.25 to 0.57).

CONCLUSIONS

This is the first study highlighting an association between the symptoms relevant to the two chronic conditions RLS and endometriosis, showing that women with a reported prior surgical diagnosis or symptoms suggestive of endometriosis have a significantly higher prevalence of a prior formal diagnosis or symptoms suggestive of RLS. This data will help in facilitating the discovery of novel therapeutic targets relevant to both conditions. The simultaneous treatment of these conditions could potentially lead to improvement in the overall quality of life for these women.

The Effects and Mechanisms of Exercise on the Treatment of Depression

Background: It is necessary to seek alternative therapies for depression, because side effects of medications lead to poor adherence and some patients do not achieve a clinical treatment effect. Recently the role of exercise as a low-cost and easy-to-use treatment for depression has gained attention with a number of studies showing that exercise is effective at reducing depressive symptoms and improving body functions such as cardiorespiratory system and cognitive function. Because of the heterogeneity of exercise therapy programs, there is no standardized and unified program. Few studies have summarized the specific properties of exercise programs (type, intensity, duration, and frequency) and clinical prescriptions for exercise are not mentioned in most articles. Aims: This study aimed to investigate the feasibility and efficacy of exercise therapy for patients with depression, in order to appraise the evidence and outline accepted guidelines to direct individualized treatment plans for patients with depression based on their individual situations. Methods: A systematic review of English language literature including papers published from 2010 to present in PubMed was performed. Given the feasibility of prescribing exercise therapy for patients with depression, nearly 3 years of clinical studies on the treatments of depressive symptoms with exercise were first reviewed, comparing the exercise programs utilized. Conclusions: Exercise has therapeutic effects on depression in all age groups (mostly 18-65 years old), as a single therapy, an adjuvant therapy, or a combination therapy, and the benefits of exercise therapy are comparable to traditional treatments for depression. Moderate intensity exercise is enough to reduce depressive symptoms, but higher-dose exercise is better for overall functioning. Exercise therapy has become more widely used because of its benefits to the cardiovascular system, emotional state, and systemic functions. Recommendations: Aerobic exercise/mind-body exercise (3-5 sessions per week with moderate intensity lasting for 4-16 weeks) is recommended. Individualized protocols in the form of group exercise with supervision are effective at increasing adherence to treatment.

The effects of an olive-oil massage on hemodialysis patients suffering from fatigue at a hemodialysis unit in southern India - a randomized controlled trial

OBJECTIVES

To determine the effects that an olive oil massage has on fatigue among patients undergoing hemodialysis, and the associated sociodemographic factors that can reduce fatigue.

METHODS

The study used true experimental pre- and post-test research design. A total of 200 patients were recruited in a selected hemodialysis unit in southern India and were allocated to either a study or control group by randomization, with 100 patients in each group. All the patients in the intervention group were given a lower back and lower leg massage using olive oil at the beginning, and after every hour, of their hemodialysis using olive oil for a period of eight weeks. In contrast, the control group continues to receive routine care. The level of fatigue was measured using the Fatigue Severity Scale both before and after massage therapy.

RESULTS

Between 73 and 80% of patients were suffering from severe fatigue and the mean fatigue score was 5.53 (SD 1.82) and 5.56 (SD 1.57) for the study and control group, respectively. After eight weeks of massage therapy, the results showed that 53% of patients in the study group showed borderline fatigue, with a mean score of 4.39 (SD 2.37), whereas in the control group 73% patients showed severe fatigue, with a mean score of 5.17 (SD 2.00). The independent t-test between the study and the control group showed a statistically significant reduction in fatigue in the study group with a mean difference (MD) of 3.56 (t=-1.24; p=0.000). There were also statistically significant changes noted in gender and in the duration of the hemodialysis (χ ² = 6.043; p=0.049) and (χ ² = 6.611; p=0.046) respectively.

CONCLUSION

The study concluded that patients undergoing hemodialysis experienced moderate to severe levels of fatigue. In patients with no or mild anemia, massage has been shown to decrease fatigue and increase energy levels among patients undergoing hemodialysis for chronic kidney disease.

Dialysis Patients With Restless Leg Syndrome: Can We Relieve Their Suffering?

Restless leg syndrome (RLS), also called Willis Ekbom disease, can be described as an unpleasant feeling that intensely urges the patients to move their lower limbs. RLS is classified into primary and secondary. It is one of the common complications in hemodialysis patients, and it impairs patients’ quality of life. Unfortunately, it is an underdiagnosed and undertreated disorder. In this review article, we performed a literature search using the PubMed database to compare different treatment modalities for RLS in patients with end-stage renal disease (ESRD) on regular hemodialysis. Many of the non-pharmacologic modalities of treatment are cost-effective and safer than pharmacologic therapy. Given the small sample size of the studies and short follow up duration, we should consider conducting studies on a larger number of patients and for longer periods of time to assess the efficacy and safety of different treatment patterns for RLS in hemodialysis patients. We hope to raise awareness about this neurologic condition in hemodialysis patients.

Daily physical activity in patients on chronic haemodialysis and its relation with fatigue and depressive symptoms

OBJECTIVE

Fatigue and depressed mood are considered main impediments to physical activity in haemodialysis (HD) patients. A better understanding of their interrelationships is crucial to develop effective therapies. Moreover, measurement of daily physical activity (DPA) in HD patients is tricky, as it is usually assessed by subjective self-report questionnaires. Therefore, we aimed to objectively measure sponteanous DPA with motion sensors and to explore its relation with fatigue and depressive symptoms.

METHODS

DPA was assessed for seven consecutive days in 37 HD patients based on their daily step count measured with the SenseWear™ Armband. The Fatigue Severity Scale (FSS) and Beck Depression Inventory-II (BDI-II) were administered to evaluate fatigue and depressed mood.

RESULTS

Median DPA was 2424 steps/day, (IQR:892-4545). In 81% of subjects, DPA felt within a sedentary lifestyle classification, as they made < 5.000 steps/day. DPA did not correlate with fatigue (r_s = 0.04, p = 0.832), and did not significantly differ between patients categorized as clinically fatigued (n = 23, FSS ≥ 4) or not (n = 14, FSS < 4) (p = 0.654, d = 0.20). Although low-depressed subjects (n = 19, BDI-II ≤ 13) made on average 1.7 times more steps/day than high-depressed subjects (n = 18, BDI-II > 13) (p = 0.111, d = 0.60), depressive mood did also not correlate significantly with DPA (r_s = - 0.23, p = 0.175).

CONCLUSION

Objective assessment of DPA with motion sensors is feasible in HD patients and allows identifying a sedentary lifestyle. Our results suggest that spontanous DPA is determined by age rather than by fatigue or mood.
