The Role of Physiotherapy in the New Treatment Landscape for Haemophilia

Arthroscopic ankle surgery in people with haemophilia

INTRODUCTION

People with haemophilia (PWH) not administered primary haematological prophylaxis since childhood, that is, those treated haematologically on demand or not treated at all, often experience the degeneration of the ankles, leading to pain and functional impairment.

AIM

To analyse the outcomes and complications of arthroscopic ankle surgery performed on PWH.

METHODS

For this narrative review of the literature, a search was conducted in PubMed on 2, December 2023, using the keywords "haemophilia", "ankle" and "arthroscopy". Of the 29 articles identified, 15 specifically related to ankle arthroscopy in PWH were selected (inclusion criterion). The remaining articles did not meet this requirement (exclusion criterion) and were therefore eliminated.

RESULTS

Arthroscopic procedures (arthroscopic synovectomy, debridement and arthrodesis of the ankle) are increasingly used in the surgical treatment of haemophilic ankle arthropathy. Although arthroscopic ankle surgery offers good outcomes in patients with haemophilia, the procedure is not free of complications, which range from 7.9% for arthroscopic ankle debridement to 13.1% in arthroscopic ankle synovectomy and 17.8% in arthroscopic ankle arthrodesis, respectively. The non-union rate of arthroscopic ankle arthrodesis is 7.1% (2/28).

CONCLUSION

Although arthroscopic interventions in the haemophilic ankle (synovectomy, debridement, arthrodesis) offer good functional outcomes, they are associated with a non-negligible rate of complications. Arthroscopic ankle surgery in PWH is major surgery and should be treated as such.

Foam roller-based self-induced myofascial therapy in patients with hemophilic knee arthropathy: a multicenter, single-blind, randomized clinical study

BACKGROUND

Hemophilia is a congenital coagulopathy characterized by degenerative joint damage. Self-induced myofascial therapy aims to decrease pain and improve tissue mobility, functionality and proprioception.

AIM

The aim of this study was to evaluate the safety and efficacy of self-induced myofascial release in patients with hemophilic knee arthropathy.

DESIGN

This is a randomized clinical study.

SETTING

This study was carried out in different patient associations.

POPULATION

Fifty-two patients with hemophilia were included in the study.

METHODS

Patients were randomized to the experimental group (daily home protocol of foam roller-based self-induced myofascial therapy for 8 weeks) or the control group (no intervention). The variables were the frequency of hemarthrosis (self-reporting), pain intensity (visual analog scale), range of motion (goniometry) and muscle strength (dynamometry). All variables were evaluated at baseline, post-treatment and after a 10-week follow-up.

RESULTS

The patients included in the experimental group showed significant improvements in terms of a decrease in frequency of hemarthrosis (mean difference [MD]=-0.61; 95% confidence interval [CI]: -0.81; -0.41) and pain intensity (MD=-0.33; 95% CI: -0.48, -0.18), increased range of motion (MD=0.88; 95% CI: 0.39; 1.37), strength in quadriceps (MD=0.88; 95% CI: 0.39; 1.37). (MD=12.39; 95% CI: 3.44; 21.34) and hamstrings (MD=7.85; 95% CI: 0.60; 15.11). There were intergroup differences in the frequency of hemarthrosis (F=14.51; P<0.001), pain intensity (F=9.14; P<0.001) and range of motion (F=13.58; P<0.001).

CONCLUSIONS

Self-induced myofascial therapy can be an effective complementary technique in the treatment of patients with hemophilic arthropathy. Self-induced myofascial therapy can reduce the frequency of knee hemarthrosis in patients with hemophilia. This technique can improve pain intensity and range of motion in patients with hemophilic knee arthropathy.

CLINICAL REHABILITATION IMPACT

Hemophilic knee arthropathy is characterized by chronic pain, decreased range of motion, and periarticular muscle atrophy. Foam roller-based self-induced myofascial therapy can reduce the frequency of hemarthrosis and pain intensity and improve range of motion in patients with hemophilic arthropathy. Foam roller-based self-induced myofascial therapy is safe and effective in the treatment of patients with hemophilia. The inclusion of self-induced myofascial therapy exercises in the approach to degenerative joint pathologies may be an effective and safe treatment option.

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.

Building the foundation for a community-generated national research blueprint for inherited bleeding disorders: research priorities to transform the care of people with hemophilia

BACKGROUND

Decades of research have transformed hemophilia from severely limiting children's lives to a manageable disorder compatible with a full, active life, for many in high-income countries. The direction of future research will determine whether exciting developments truly advance health equity for all people with hemophilia (PWH). National Hemophilia Foundation (NHF) and American Thrombosis and Hemostasis Network conducted extensive inclusive all-stakeholder consultations to identify the priorities of people with inherited bleeding disorders and those who care for them.

RESEARCH DESIGN AND METHODS

Working group (WG) 1 of the NHF State of the Science Research Summit distilled the community-identified priorities for hemophilia A and B into concrete research questions and scored their feasibility, impact, and risk.

RESULTS

WG1 defined 63 top priority research questions concerning arthropathy/pain/bone health, inhibitors, diagnostics, gene therapy, the pediatric to adult transition of care, disparities faced by the community, and cardiovascular disease. This research has the potential to empower PWH to thrive despite lifelong comorbidities and achieve new standards of wellbeing, including psychosocial.

CONCLUSIONS

Collaborative research and care delivery will be key to capitalizing on current and horizon treatments and harnessing technical advances to improve diagnostics and testing, to advance health equity for all PWH.

How to translate and implement the current science of gene therapy into haemophilia care?

Gene-based therapy opens an entirely new paradigm in managing people with haemophilia (PWH), offering them the possibility of a functional cure by enabling continuous expression of factor VIII (FVIII) or factor IX (FIX) after transfer of a functional gene designed to replace the PWH's own defective gene. In recent years, significant advances in gene therapy have been made, resulting in clotting factor activity attaining near-normal levels, as reflected by 'zero bleeding rates' in previously severely inflicted patients following a single administration of adeno-associated viral (AAV) vectors. While this new approach represents a major advancement, there are still several issues that must be resolved before applying this technology in clinical practice. First, awareness, communication, and education about the therapeutic potential and modalities of gene therapy must be further strengthened. To this end, objective, unbiased, transparent, and regularly updated information must be shared, in an appropriate way and understandable language with the support of patients' organizations. Second, healthcare providers should adopt a patient-centred approach, as the 'one size fits all' approach is inappropriate when considering gene therapy. Instead, a holistic patient view taking into account their physical and mental dimensions, along with unexpressed expectations and preferences, is mandatory. Third, the consent procedure must be improved, ensuring that patients' interests are maximally protected. Finally, gene therapy is likely to be first delivered in a few centres, with the highest expertise and experience in this domain. Thus, patients should be managed based on a hub-and-spoke model, taking into account that the key to gene therapy's success lies in an optimal communication and collaboration both within and between haemophilia centres sharing their experiences in the frame of international registries. This review describes recent progress and explains outstanding hurdles that must be tackled to ease the implementation of this paradigm-changing new therapy.

Activity and participation in haemophiliacs: Item response modelling based on international classification of functioning, disability and health

BACKGROUND AND OBJECTIVES

There is scant research investigating the user-friendly functional assessment tool conceptualized by the International Classification of Functioning, Disability and Health (ICF) among persons with haemophilia (PWH). This study aims to accomplish two goals: (1) quantifying comprehensive functioning measures of haemophilia through Item Response Theory (IRT); (2) discussing patient-centred care based on the Wright map of personal ability and item difficulty.

METHODS

A cross-sectional study was carried out in 70 PWH (mean age, 33.09 ± 11.04) via convenience sampling. All patients completed the 45 ICF categories of haemophilic-specific activity and participation. Psychometric properties of the categories were examined using Mokken scale analysis and parametric item response modelling.

RESULTS

We extracted a unidimensional scale with 31 categories, and constructed a Rasch model with good fitness. The Cronbach's α of the scale was .9713, with the Guttman's λ²  = .9730, Molenaar Sijtsma ρ = .9802, and latent class reliability coefficient = .9769, indicating great internal reliability. The estimated individual social competence by the Rasch model was highly related to the index score of the three-level EuroQol five-dimensional questionnaire (EQ-5D-3L) (p < .001, r = .62), and had a moderate correlation (p < .001, r = .54) with the score of Haemophilia Activities List (HAL).

CONCLUSIONS

The ICF scale of haemophilic activity and participation with 31 categories (HAPPY-ICF) has good construct validity and internal consistency. The person-item threshold distribution map might be helpful in research and clinical practices for patient-oriented care.

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.

Promoting physical activity for people with haemophilia in the age of new treatments

Haemophilia treatment has seen great advances in recent years with an accompanied reduced risk of physical activity (PA) related bleeds. Based on its known health benefits, people with haemophilia (PWH) are currently encouraged to regularly engage in PA. However, this may not always translate to increased levels of PA. In this narrative review we aim to provide a brief overview of what is currently understood regarding PA levels and influences for the three broad age groups of children and adolescents, adults and older adults. We also provide recommendations for members of the haemophilia team on important aspects related to promotion of PA in their clinical practice. We highlight that PA behaviour is multifactorial and that many PWH still have limited access to adequate care. Whilst some still face unique challenges to being more physically active, overall, the barriers and facilitators to activity are very similar to that of the general population.

Hemophilic Arthropathy: Barriers to Early Diagnosis and Management

Hemophilia is a congenital coagulopathy characterized by a deficiency of one of the clotting factors. It is characterized by the development of hematomas and hemarthrosis, either spontaneously or after minor trauma. The recurrence of hemarthroses leads to progressive and degenerative joint damage from childhood (hemophilic arthropathy). This arthropathy is characterized by disabling physical effects that limit the functionality and quality of life of these patients. Medical progress achieved over the last decade in the drug treatment of hemophilia has improved the medium and long-term prospects of patients with more effective and long-lasting drugs. The universal use of safer, more effective and prolonged prophylactic treatments may promote the prevention of bleeding, and also therefore, of the development of hemarthrosis and joint damage. A number of imaging instruments have been developed for the assessment of hemarthrosis and hemophilic arthropathy, using ultrasound, magnetic resonance imaging and simple radiology. Different physical examination scores and questionnaires allow the assessment of joint health, self-perceived activity and functionality of patients with hemophilia. The approach to these patients should be interdisciplinary. Assessment of the processes that affect pain in these patients and the development of pain education models should be implemented. Expert advice and information to patients with hemophilia should be based on individual functional prevention diagnoses, advice on available therapies and sports practice, as well as health recommendations.

Hemophilia Patient Experience in a Physical Therapy-Guided Health Education Intervention: A Mixed-Method Design

People with hemophilia usually have negative joint consequences due to their illness. Evidence suggests that exercise and therapeutic education bring some benefits. An important factor that affects health interventions was the experience and degree of satisfaction. Thus, it is relevant to analyze qualitative and quantitative data to obtain a complete view of the patient’s experience. As a result, a concurrent nested mixed method with quantitative predominance study design was carried out. Nine people with hemophilia of Hemoaralar with a homogeneous environment participated in this study. The items evaluated were the level of satisfaction through the GCPC-UN-ESU survey and the experience with healthcare interventions through a focus group. A high level of satisfaction was obtained, but some divergences between quantitative and qualitative data were found. Further research about physical therapy and this type of intervention in people with hemophilia should be considered to better address the impact of living with the disease.
