RCT of a 6-month programmed sports therapy (PST) in patients with haemophilia - Improvement of physical fitness

Effects of resistance training on muscle strength in adults with haemophilia: A systematic review and meta-analysis

INTRODUCTION

Although resistance training is frequently prescribed for people with haemophilia (PWH), no previous meta-analyses have quantified the effect of this intervention on muscle strength, nor the implications of the intervention's modality and duration.

AIM

(1) To determine the effects of resistance training on muscle strength in adults with haemophilia; (2) To determine the most effective duration and modality among the exercise protocols.

METHODS

A systematic search from inception until 28 November 2023 was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases. We included randomised controlled trials or before-after studies that involved resistance training without other physiotherapy co-interventions. Study selection, data extraction and risk of bias assessment were independently performed by two reviewers. Disagreements were resolved in consultation with a third author. The level of evidence was determined according to the GRADE methodology.

RESULTS

Seven studies were included. Measurements of knee extensor strength and elbow extensor strength were included in the meta-analysis. Subgroup analysis showed significant effects for both elastic resistance protocols (SMD: 0.54; 95% CI: 0.02-1.07) and conventional training (isometric and weight-based equipment) (SMD: 0.88; 95% CI: 0.50-1.25), demonstrating small and moderate effect sizes respectively. Additionally, both protocols of duration 5-7 weeks (SMD: 1.16, 95% CI: 0.63-1.69) as well as those of duration ≥8 weeks (SMD: 0.57, 95% CI: 0.20-0.94) showed a significant difference.

CONCLUSION

Resistance training is effective in improving muscle strength of the knee and elbow extensors in PWH. Both elastic resistance and conventional training show benefits.

Efficacy of rehabilitation interventions on functioning in patients with hemophilic arthropathy: A systematic review with meta-analysis

BACKGROUND

Hemophilic arthropathy is a detrimental condition that crucially affects functional outcomes in hemophilic patients. In recent years, due to the advances in systemic therapies, growing attention has been raised in the rehabilitation field in order to improve functional outcomes of hemophilic patients. However, the optimal rehabilitation modalities in these patients are far from being fully characterized.

OBJECTIVE

The present study aimed to assess the effects of different rehabilitation interventions on physical functioning and health-related quality of life of hemophilic arthropathic patients.

METHODS

The review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Five databases were systematically searched for randomized controlled trials (RCTs) published until June 22nd, 2023. The selection criteria included adult patients with hemophilia A and B receiving rehabilitation interventions. The outcomes were muscle strength, physical function, pain intensity, physical performance, and health-related quality of life.

RESULTS

Out of 1,743 identified records, 17 studies were included in the qualitative synthesis. Rehabilitation interventions were categorized into exercise intervention, fascial therapy, and multimodal intervention. The findings suggested positive outcomes in terms of muscle modifications, range of motion improvements, joint health enhancements, pain intensity reduction, and quality of life improvements. More in detail, meta-analyses showed significant improvements in pain intensity [ES: -1.10 cm (-1.37, -0.82), p< 0.00001], joint health [ES: -1.10 (-1.38, -0.82), p< 0.00001], In accordance, exercise interventions showed significant benefits in terms of joint health [ES: -2.54 (-3.25, -1.83), p< 0.00001)] and quality of life [ES: 1.17 (0.48, 1.86), p< 0.0000)].

CONCLUSION

Rehabilitation interventions have a positive impact on functional outcomes and health-related quality of life of hemophilic arthropathic patients. Further studies are needed to better elucidate the role of a comprehensive intervention combining different rehabilitation approaches to treat hemophilic arthropathy.

Identifying performance-based outcome measures of physical function in people with haemophilia (IPOP)

INTRODUCTION

Recent recommendations of core outcome sets for haemophilia highlight the need for including measures of performance-based physical health and physical function sustainability. To date, there is no consensus on what outcomes might be of value to clinicians and patients.

AIM

To identify instruments of performance-based physical function to monitor musculoskeletal health in people with haemophilia that are practical in the clinical setting.

METHODS

Utilising components from the Activities and Participation Category of the WHO International Classification of Functioning (WHO-ICF), a consensus-based, decision analysis approach was used to: identify activities people with haemophilia have most difficulty performing; identify quantitative performance-based measures of identified activities via a scoping review; and obtain views on acceptability of the tests utilising a DELPHI approach.

RESULTS

Eleven activities were identified: maintaining a standing position, walking long distances, walking up and down stairs, walking on different surfaces, running, hopping, jumping, squatting, kneeling, undertaking a complex lower limb task, undertaking a complex upper limb task. Following a 2-round DELPHI survey of international physiotherapists, the 6-min walk test, timed up and down stairs, 30-s sit to stand, single leg stance, tandem stance, single hop for distance (children only) and timed up and go (adults only) reached consensus.

CONCLUSION

This study is the first step in defining a core set of performance-based instruments to monitor physical health and sustainability of physical function outcomes in people with haemophilia. Establishing the psychometric properties of the instruments and whether they are meaningful to people with haemophilia is essential.

The Efficacy of Physical Therapy Modalities in Patients With Hemophilia: A Systematic Review of Randomized Controlled Trials With Meta-analysis

OBJECTIVE

To evaluate the efficacy of different physical therapy interventions that could validate decisions taken by health care providers in the field of rehabilitation of patients with hemophilia according to the International Classification of Functioning, Disability and Health (ICF), including body functions and structures, activity, and participation.

DATA SOURCES

Seven databases-PubMed, Cochrane Library, Scopus, Web of Science, Physiotherapy Evidence Database, Google Scholar, and Clinicaltrials.gov-were systematically searched for randomized controlled trials evaluating any physical therapy modality to manage hemophilia.

STUDY SELECTION

After abstract and full-text filtration, a methodological quality assessment was performed using the Physiotherapy Evidence Database scale for the studies that met the eligibility criteria.

DATA EXTRACTION

Relevant data were extracted from eligible studies and outcomes were categorized according to the ICF.

DATA SYNTHESIS

Using Review Manager and Microsoft Excel, a quantitative analysis using standardized mean differences with the 95% confidence interval was completed. Statistical heterogeneity between studies was explored using the I² test. A fixed effect model was applied to all data analyses. If heterogeneity was statistically significant, the Der Simonian and Laird random effects models were used instead.

RESULTS

35 randomized controlled trials with 1216 participants were included in this systematic review; 13 of them dealt with pediatric patients. Most of the studies were of good quality; 12 studies were of low quality. Meta-analysis showed a significant difference in favor of manual therapy, laser, and therapeutic exercises on selected outcomes of body function and structure, activity, and participation categories of the ICF model.

CONCLUSION

This systematic review recommends using manual therapy and therapeutic exercise modalities to improve join health status in combination with educational sessions to improve the quality of life of patients with hemophilic arthropathy. For pediatric patients with hemophilic arthropathy, using laser therapy is promising for improving functional capacity.

Pathogenesis and treatment of osteoporosis in patients with hemophilia

INTRODUCTION

Hemophilia is a rare X-linked recessive inherited bleeding disorder caused by mutations of the genes encoding coagulation factor VIII (FVIII) or IX (FIX). Patients with hemophilia (PWH) often have a high risk of osteoporosis and fractures that is usually ignored. Herein, we review the underlying mechanisms of osteoporosis and the increased risk of fractures and their treatment in patients with FVIII or FIX deficiency.

METHODS

The PubMed, Web of Science, Embase, and Cochrane Library databases were searched to identify original research articles, meta-analyses, and scientific reviews on the mechanisms or treatment of osteoporosis in PWH.

RESULTS

The pathogenic mechanisms of osteoporosis in PWH are multifactorial and remain unclear. The available evidence shows that FVIII and FIX deficiency may directly affect bone metabolism by interfering with the RANK/RANKL/OPG pathway. Other potential mechanisms of osteoporosis in PWH include thrombin deficiency and the unloading and immobilization of bone, which will affect osteoblast and osteoclast activity by changing the cytokine profiles. The treatment of osteoporosis in PWH includes antiresorptive, anabolic, and dual-action drugs; weight-bearing exercise; fall prevention; and prophylactic coagulation factor replacement therapy. However, clinical studies of the efficacy of anti-osteoporotic agents in osteoporosis of PWH are urgently needed.

CONCLUSION

This review summarizes recent progress in research on the pathogenesis of osteoporosis in PWH and provides insights into potential treatment for osteoporosis in PWH.

The evolution of physiotherapy in the multidisciplinary management of persons with haemophilia (PWH): A scoping review

INTRODUCTION

Haemophilia is a rare congenital bleeding disorder, and the most common manifestation is spontaneous bleeding in muscles and joints. Despite the benefits linked to recent and dramatic pharmacological advances at least in high income setting, many patients still develop musculoskeletal dysfunctions during their lifetime, which must be managed by physiotherapists in the frame of a multidisciplinary team. The aim of the scoping review is to map the available evidence by providing an overview on the past and present physiotherapy scenario in persons with haemophilia (PWH).

MATERIALS AND METHODS

The review was conducted according to the guidelines of the PRISMA extension for scoping reviews. Scientific articles on physiotherapy and sport interventions for PWH published from 1960 up to September 2021 have been included. Search was conducted on the e-databases PubMed and PEDro without restrictions for the study design.

RESULTS

Sixty eight articles were included, 52 related to rehabilitation and preventive physiotherapy, 16 to sport. The results have been reported in chronological order and divided into two categories: (1) rehabilitation and preventive physiotherapy; (2) sport activities.

CONCLUSIONS

This is the first scoping review on physiotherapy in haemophilia, based on the existing evidence on this topic which allowed us to underline how the role of the physiotherapist changed over time. Historically this specialist did intervene only after an acute bleed or surgical operation, but now he has a pivotal role in the multidisciplinary team that acts to improve from birth the quality of life of the PWH. His activity is also closely intertwined with sport promotion and supervision.

Effectiveness of physical exercise on postural balance in patients with haemophilia: A systematic review

INTRODUCTION

Balance training is important to improve balance and to decrease the risk of falls in patients with haemophilia (PWH).

AIM

To analyse the current knowledge about the effectiveness of physical exercise on postural balance in PWH.

METHODS

A systematic search for clinical trials, published before November 2021, was conducted using the following electronic databases: PubMed/MEDLINE, Web of Science, Embase, Wiley Online Library and the Cochrane Central Register of Controlled Trials (CENTRAL). Two independent reviewers extracted the data and assessed the risk of bias. The certainty of the evidence was analyzed using GRADE.

RESULTS

A total of ten studies involving 304 patients were included. The studies performed strength and balance exercises, and some included flexibility, mobilization, and/or aerobic exercises in their training programs. Postural balance was evaluated using a force platform and the one leg stand test was the most frequently used. Only five exercise programs achieved a significant increase in balance (pre-post) with a strength, postural balance, flexibility, and aerobic intervention. In general, the quality rate of the risk of bias was fair but the overall quality of the evidence across the studies was very low.

CONCLUSION

Five studies showed that there is a positive change in balance after the intervention. However, there is currently an unclear demonstration of evidence for the use of physical exercises to improve postural balance in people with haemophilia. Further studies with a higher methodological quality are needed.

Osteoporosis management and falls prevention in patients with haemophilia: Review of haemophilia guidelines

INTRODUCTION

Patients with haemophilia (PWH) have a high prevalence of osteoporosis, falls and fractures at all ages. The role of haemophilia itself may contribute to low bone mineral density (BMD) due to coagulation factor deficiency. Guidelines for the management of osteoporosis, fracture and fall risk may help to reduce fracture and fall risk, and delay osteoporosis onset.

AIM

We aim to review current haemophilia guidelines regarding osteoporosis prevention, screening, diagnosis and management, and fall prevention.

METHOD

A database search (Ovid MEDLINE) revealed two haemophilia guidelines (World and British) published within the last ten years. Local Australian haemophilia guidelines were identified through a manual search.

RESULTS

All haemophilia guidelines were found to contain inadequate recommendations for osteoporosis management and fall prevention due to a lack of evidence in the literature.

CONCLUSION

Further studies are required to assess the trajectory of bone health in PWH, the mechanism of bone loss in PWH, and the effectiveness of weight-bearing exercises, interventions for fall prevention, screening programmes, and use of anti-osteoporosis medications in PWH across the lifecourse.

Promoting physical activity in people with haemophilia: the MEMO (Movement for persons with haEMOphilia) expert consensus project

Regular physical activity can increase joint stability and function, reduce the risk of injury, and improve quality of life of people with haemophilia (PwH). However, a recent review of the literature shows that appropriate physical activity and sport are not always promoted enough in the overall management of PwH. A group of Italian experts in haemophilia care undertook a consensus procedure to provide practical guidance on when and how to recommend physical exercise programmes to PwH in clinical practice. Three main topics were identified -haemophilia and its impact on movement, physical activity recommendations for PwH, and choice and management of sports activity in PwH- and ten statements were formulated. A modified Delphi approach was used to reach a consensus. The group also created practical tools proposing different physical activities and frequencies for different age groups, the Movement Pyramids, to be shared and discussed with patients and caregivers. In conclusion, in the opinion of the working group, physical activity can be considered as a low-price intervention that can prevent/reduce the occurrence of chronic diseases and should be further encouraged in PwH to obtain multiple physical and psychological benefits. Future research should include prospective studies focusing on participation in sports, specific risk exposure and clinical outcomes.

Safety and Effectiveness of Progressive Moderate-to-Vigorous Intensity Elastic Resistance Training on Physical Function and Pain in People With Hemophilia

OBJECTIVE

Strength training is recommended for people with hemophilia; however, published data are anecdotal and have methodological limitations. The purpose of this study was to evaluate the safety and effectiveness of progressive moderate-to-vigorous intensity elastic resistance training on physical function and pain in this patient population.

METHODS

A randomized controlled trial was conducted in a university laboratory setting where 20 patients (17 with severe, 1 with moderate, and 2 with mild hemophilia) aged 21 to 53 years received evaluations at baseline and 8-week follow-up. Participants were allocated to intervention (progressive strength training) or control (usual daily activities) groups. The intervention group trained 2 days per week during 8 weeks with elastic resistance. Intensity during the first 2 weeks was a 20-repetition maximum and increased progressively toward 15, 12, and finally 10 repetition maximum. The primary outcome was muscle strength. Secondary outcomes were the Timed "Up and Go" Test score, sit-to-stand, range of motion, Haemophilia Joint Health Score, kinesiophobia score, global impression of pain change, general self-rated health status, and desire to exercise.

RESULTS

The intervention group showed greater strength improvements than the control group in almost all of the joints, with moderate to high effect sizes. The intervention group also showed better Timed "Up and Go" and sit-to-stand scores than the control group (moderate effect size), greater range of motion at the knee flexion with the right leg (trivial effect size), and better Haemophilia Joint Health Score at the left knee (small effect size). The intervention group showed greater overall pain reduction, self-rated overall status, and desire to exercise than the control group.

CONCLUSIONS

Progressive strength training with elastic resistance performed twice a week during 8 weeks is safe and effective in people with hemophilia to improve muscle strength and functional capacity, reduce general pain, and improve self-rated health status and desire to exercise.

IMPACT

This study provides evidence for the use of a specific strength training regimen for people with hemophilia.

LAY SUMMARY

People with hemophilia of differing levels of severity, with adequate coverage with clotting factor, can safely engage in progressive strength training and can improve their functioning.

The effect of resistance exercise on strength and safety outcome for people with haemophilia: A systematic review

Introduction

Haemophilia is a congenital bleeding disorder with severe musculoskeletal complications. Resistance exercise is important to increase joint stability and to improve physical performance.

Aim

This review aimed to investigate the safety and efficacy of resistance exercise interventions on people with haemophilia (PwH) and evaluate whether the American College of Sports Medicine resistance exercise criteria for healthy adults are valid for this population.

Methods

A systematic search in literature was conducted, using the databases PubMed, MEDLiNE, CINAHL, SCOPUS, PEDro and Cochrane Library. Out of 2.440 studies published between 1960 and November 2019, 14 studies (9 randomized controlled trials, 1 controlled trial, 4 single‐group prospective studies) applying resistance exercise in juvenile and adult PwH corresponded to the inclusion criteria.

Results

Studies performed dynamic, isokinetic or a combination of isometric and dynamic resistance training. Most interventions were carried out in the context of a multimodal training. Resistance was provided using fixed and free weights, body weight, resistance bands and water resistance. Study protocols included clinical and home‐based settings. Several studies suggest that training intensities lower than those known to increase the strength of healthy people are effective in increasing the strength of PwH. Resistance exercise seems to be a safe intervention if it is adequately monitored, individually adapted and applied with sufficient factor therapy. Due to the heterogeneity of study designs, training interventions and outcome measures a meta‐analysis could not be performed.

Conclusions

Further studies of higher methodological quality are needed to determine the optimal types of exercise, optimal dosage and timing.

Establishing an online physical exercise program for people with hemophilia

BACKGROUND

Hemophilia is a congenital bleeding disorder with an estimated frequency of 1:10,000 births. Repeated joint bleeding is a hallmark of the disorder and leads to painful hemophilic arthropathy. Regular exercise can help improve joint stability and function, reduce the risk of injury and bleeding and improve physical fitness and quality of life. This method paper describes an online training concept aiming to offer access to appropriate exercise instructions for people with hemophilia who are not able to attend regular training at a hemophilia center.

METHODS

The online exercise program is accessible through the homepage of the Department of Physical Medicine, Rehabilitation and Occupational Medicine of the Medical University Vienna as well as through scanning a QR code printed on information material using a smart phone or tablet.

RESULTS

The program contains exercises to improve mobility, coordination, muscular strength and flexibility. A brief introduction is given by a hematologist, a pediatrician and a physiatrist. An introductory video informs about contraindications and essential precautions, such as medical attendance and sufficient factor therapy to consider before starting the training. Another video gives advice on the exercise composition. The demonstrated exercises are explained by a physician and are available for adults and children. To individualize training recommendations and offer further diagnostic tools and physical treatment options as necessary, the Department of Physical Medicine, Rehabilitation and Occupational Medicine of the Medical University of Vienna will establish consultation hours for people with hemophilia.

CONCLUSION

As hemophilia is an orphan disease, patients are mainly treated in specialized centers. For patients who live far from these centers or have limited access to a training there for other reasons, the physical medicine consultation hour and the implementation of online exercise instructions offer individually adapted exercise information for a regular home-based training to benefit from increased physical fitness and joint stability.

Recent advances in musculoskeletal physiotherapy for haemophilia

Physiotherapy is directed towards the movement needs and potential of individuals, providing treatment and rehabilitation to develop, maintain and restore maximum movement and functional ability throughout the lifespan. Recent systematic reviews and randomized controlled trials have extended evidence for the clinical efficacy of physiotherapy interventions and rehabilitation for people with haemophilia. This narrative review synthesizes recent evidence to discuss; differentiating musculoskeletal bleeding and haemophilic arthropathy, efficacy of physiotherapy and rehabilitation for acute musculoskeletal bleeding and arthropathy, as well as monitoring musculoskeletal health. Whilst robust evidence is emerging, there is a need for more well designed randomized clinical studies with larger numbers and homogeneity of participants and collaboration of all researchers and clinicians to identify a core set of outcome measures that can be used to monitor musculoskeletal health.

Cost-utility of a six-month programmed sports therapy (PST) in patients with haemophilia

INTRODUCTION

Recurrent musculoskeletal haemorrhages in people with haemophilia (PwH) lead to restrictions in the locomotor system and, as a result, in physical performance, too. Due to its physical and psychological benefits, sport is increasingly re-commended for haemophilic patients. Evidence on the cost-effectiveness of sports therapy is still lacking.

AIM

The aim of this study was to determine the cost-effectiveness of a 6-month programmed sports therapy (PST).

METHODS

The cost-effectiveness of the 6-month PST was assessed from a societal perspective alongside a RCT using cost-utility analysis. The analysis included 50 PwH with moderate-to-severe haemophilia A and B and a training period over 6 months. The health-related quality of life was measured with the EuroQoL-domain questionnaire. Resource utilization was assessed by questionnaire before and after the intervention. A cost-effectiveness acceptability curve was constructed, and sensitivity analyses were performed.

RESULTS

During the 6-month study period, mean adjusted total healthcare costs were lower (mean difference: -22 805 EUR; 95%-CI: -73 944-48 463; P = .59) and the number of QALYs was higher in the intervention group (mean difference: 0.3733; 95%-CI: 0.0014-0.0573; P = .04). The probability of an incremental cost-effectiveness ratio <50 000 EUR per QALY was 71%. The performed sensitivity analysis confirmed these results.

CONCLUSION

Results showed that the PST is effective in terms of a significant gain of QALYs. Furthermore, results weakly indicate the potential of the PST to reduce healthcare costs. Future studies should expand the observation period to have a closer look at the influence of PST on lifetime costs.

Programmed Sports Therapy (PST) in People with Haemophilia (PwH) "Sports Therapy Model for Rare Diseases"

Sports and exercise therapy becomes more and more integrated in the treatment plan of different diseases. Although the benefits of this therapy are of high quality evidence, e.g. in cardiovascular diseases, no concepts of sports therapy are available as a treatment option for rare diseases.

During the last eighteen years, we analyzed the situation as well as necessity, and developed a model, contents and the concept of the “Programmed Sports Therapy (PST)” for the treatment of PwH (people with haemophilia) as our model of rare disease. Many studies have shown that motoric skills are depressed in PwH, and that this gap to healthy people increases during age. The only way to reduce this progression is an appropriate therapy, adapted to the necessities of PwH. In haemophilia, in particular, physio- and sports therapy treatments should go hand in hand, the first in the acute phase after bleeding, the second later, after the acute phase has finished. One model, which considers all the different challenges, can be the cogwheel model presented here. Since haemophilia is a rare disease, new training concepts are necessary because classical group therapies are often impossible. PST based on the combination of sports therapy camps together with a supervised autonomous home training helps to directly bring the training to the trainee, in order to enhance key competences and improve the individual situation in PwH, and perhaps in patients with other rare diseases.

The experience and scientific data substantiate the success of “Programmed Sports Therapy (PST)” and even this can be a model for other rare diseases.
