Moderate- to vigorous-intensity physical activities for hemophilia A patients during low-dose pharmacokinetic-guided extended half-life factor VIII prophylaxis. Orphanet J Rare Dis 2024; 19:135. [PMID: 38532451 DOI: 10.1186/s13023-024-03092-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Accepted: 02/21/2024] [Indexed: 03/28/2024] Open
Abstract
BACKGROUND Low-dose pharmacokinetic (PK)-guided extended half-life (EHL) factor VIII (FVIII) prophylaxis can reduce the bleeding risk in hemophilia A (HA) patients. An increase in physical activities for promoting musculoskeletal health may enhance the benefits of prophylactic therapy. OBJECTIVES To determine the clinical impact of moderate- to vigorous-intensity physical activities in HA patients during low-dose PK-guided EHL FVIII prophylaxis. PATIENTS/METHODS This prospective study enrolled patients with moderate/severe HA (baseline FVIII levels ≤ 5 IU/dL) who had received low-dose PK-guided EHL FVIII prophylaxis for ≥ 6 months. An individualized exercise protocol was introduced to each participant, targeting a 65% increase in the maximum predicted heart rate for ≥ 150 min/week, while continuing low-dose PK-guided EHL FVIII prophylaxis for 6 months. Before and after implementing the intervention, annualized bleeding rates (ABR), annualized joint bleeding rates (AJBR), Hemophilia Joint Health Scores (HJHS), skeletal muscle mass, hemophilia-specific quality-of-life (QoL) scores and annualized FVIII consumption were compared. RESULTS Of 13 participants (mean age ± standard deviation [SD]: 20.1 ± 6.8 years), ABR, AJBR, and HJHS were significantly reduced (mean differences [MD] ± SD: -5.7 ± 2.6 bleeds/year, -4.2 ± 2.6 joint bleeds/year, and -4.3 ± 3.2 marks, respectively; P < 0.05) after applying the 6-month exercise protocol. Skeletal muscle mass and QoL scores had also improved (P = 0.001), while FVIII usage had decreased (MD ± SD: -129.1 ± 208.7 IU/kg/year; P < 0.05). CONCLUSIONS The combination of moderate- to vigorous-intensity physical activities with low-dose PK-guided EHL FVIII prophylaxis improves bleeding prevention, musculoskeletal status and QoL in patients with moderate/severe HA. By minimizing FVIII consumption, this strategy helps optimize hemophilia care in countries with budget constraints. CLINICALTRIALS gov NCT05728528.

Using reference equations to standardise incremental shuttle walk test performance in children and young people with chronic conditions and facilitate the evaluation of exercise capacity and disease severity.

Abstract
AIMS The aim was to evaluate whether standardised exercise performance during the incremental shuttle walk test (ISWT) can be used to assess disease severity in children and young people (CYP) with chronic conditions, through (1) identifying the most appropriate paediatric normative reference equation for the ISWT, (2) assessing how well CYP with haemophilia and cystic fibrosis (CF) perform against the values predicted by the best fit reference equation and (3) evaluating the association between standardised ISWT performance and disease severity. METHODS A cross-sectional analysis was carried out using existing data from two independent studies (2018-2019) at paediatric hospitals in London,UK. CYP with haemophilia (n=35) and CF (n=134) aged 5-18 years were included. Published reference equations for standardising ISWT were evaluated through a comparison of populations, and Bland-Altman analysis was used to assess the level of agreement between distances predicted by each equation. Associations between ISWT and disease severity were assessed with linear regression. RESULTS Three relevant reference equations were identified for the ISWT that standardised performance based on age, sex and body mass index (Vardhan, Lanza, Pinho). A systematic proportional bias of standardised ISWT was observed in all equations, most pronounced with Vardhan and Lanza; the male Pinho equation was identified as most appropriate. On average, CYP with CF and haemophilia performed worse than predicted by the Pihno equation, although the range was wide. Standardised ISWT, and not ISWT distance alone, was significantly associated with forced expiratory volume in 1 s in CYP with CF. Standardised ISWT in CYP with haemophilia was slightly associated with haemophilia joint health score, but this was not significant. CONCLUSIONS ISWT performance may be useful in a clinic to identify those with worsening disease, but only when performance is standardised against a healthy reference population. The development of validated global reference equations is necessary for more robust assessment.

Abstract
INTRODUCTION Bleeding disorders (BDs) may influence health-related quality of life (HRQoL) in children and caregivers. Measuring HRQoL gives insight into domains requiring support and provides an opportunity to evaluate the effects of novel therapies. AIM To gain insight in the current body of literature on HRQoL in children with BDs in order to identify knowledge gaps for research and further development of this field. METHODS Scoping review. RESULTS We included 53 articles, describing studies mainly performed in Europe and North-America (60.4%) and mostly within the last ten years. Only 32% studies included children <4 years. Almost all studies (47/53, 88.7%) were performed in boys with haemophilia, pooling haemophilia A and B (n = 21) and different disease severities (n = 20). Thirteen different generic and five disease-specific HRQoL-questionnaires were applied; all questionnaires were validated for haemophilia specifically. Six (11,3%) combined generic and disease-specific questionnaires. Self-reports were most frequently applied (40/53, 75.5%), sometimes combined with proxy and/or parent-reports (17/53, 32.1%). Eleven studies used a reference group (20.8%). Statistical analyses mostly consisted of mean and SD (77.4%). CONCLUSION HRQoL-research is mainly performed in school-aged boys with haemophilia, treated in developed countries. Pitfalls encountered are the pooling of various BDs, subtypes and severities, as well as the application of multiple generic questionnaires prohibiting comparison of results. More attention is needed for broader study populations including other BDs, young children, feminine bleeding issues and platelet disorders, as well as the use of HRQoL as an effect-measurement tool for medical interventions, and more thorough statistical analysis.

Abstract
BACKGROUND Little is known on how sports participation affects bleeding risk in hemophilia. This study aimed to examine associations between sports participation, factor VIII (FVIII) levels and bleeding in persons with hemophilia A. METHODS In this observational, prospective, single-center study, persons with hemophilia A who regularly participated in sports were followed for 12 months. The associations of patient characteristics, FVIII levels, and type/frequency of sports participation with bleeding were analyzed by repeated time-to-event modelling. RESULTS One hundred and twelve persons (median age: 24 years [interquartile range:16-34], 49% severe, 49% on prophylaxis) were included. During follow-up, 70 bleeds of which 20 sports-induced were observed. FVIII levels were inversely correlated with the bleeding hazard; a 50% reduction of the baseline bleeding hazard was observed at FVIII levels of 3.1 and a 90% reduction at 28.0 IU/dL. The bleeding hazard did not correlate with sports participation. In addition, severe hemophilia, prestudy annual bleeding rate, and presence of arthropathy showed a positive association with the bleeding hazard. CONCLUSION This analysis showed that FVIII levels were an important determinant of the bleeding hazard, but sports participation was not. This observation most likely reflects the presence of adequate FVIII levels during sports participation in our study. Persons with severe hemophilia A exhibited a higher bleeding hazard at a similar FVIII levels than nonsevere, suggesting that the time spent at lower FVIII levels impacts overall bleeding hazard. These data may be used to counsel persons with hemophilia regarding sports participation and the necessity of adequate prophylaxis.

Abstract
INTRODUCTION Exercise capacity has been established as a protective factor against joint impairment in people with haemophilia (PWH). However, little is known about how exercise capacity is affected in PWH. AIM To analyse exercise capacity, as assessed by standardised laboratory or field tests in PWH. METHODS A systematic review was conducted to identify manuscripts investigating physical capacity in PWH. An electronic search of PubMed/MEDLINE, Embase, Web of Science, CENTRAL and CINAHL was conducted from inception to 13 April, 2022. Two independent reviewers performed data extraction and assessed study quality using the critical appraisal tools of the Joanna Briggs Institute. RESULTS Nineteen studies with 825 patients were included. Most studies used the six-min walk test (6MWT) or peak/maximal oxygen consumption (VO2 max). In children, the distance walked ranged from 274 ± 36.02 to 680 ± 100 m. In adults, the distance walked ranged from 457.5 ± 96.9 to 650.9 ± 180.3 m. VO2 max ranged from 37 ± 8 to 47.42 ± 8.29 ml kg-1 min-1 . Most studies reported lower values of exercise capacity compared to standardised values. Overall, the quality of the studies was moderate. CONCLUSION Most of the studies showed that PWH have lower exercise capacity compared to reference values of 6MWT or VO2 max. Based on these results, it is necessary to emphasise in both the promotion and the prescription of physical exercise in PWH.

Abstract
INTRODUCTION People with haemophilia suffer from haemophilic joint disease that may result in physical inactivity and overweight. Shared medical appointments (SMAs) might help limit the consequences of haemophilic arthropathy. SMAs are group meetings supervised by one or more healthcare professionals that can be utilized to improve lifestyle. AIM To evaluate the feasibility and efficacy of SMAs in people with haemophilia to improve physical activity and eating habits. METHODS A multiple baseline single-case design was used. Overweight people with haemophilia were eligible to participate. Seven weekly SMAs were conducted using multiple behavioural change techniques to improve physical activity and eating habits. Feasibility of SMAs was evaluated using (a) dropout rate, (b) occurrence of adverse events (AEs), (c) adherence rate and (d) patient satisfaction. During 13 weeks, physical activity was measured daily and eating habits were measured three times per week. The efficacy of SMAs was determined using randomization tests and visual data inspection. RESULTS Out of the six men participating in the study, one participant dropped out. No study-related AEs occurred. The adherence rate of SMAs was 80%, and participants reported to be 'very satisfied' with the SMAs. Randomization tests and visual analyses demonstrated (statistical) improvements in physical activity (p = .03). No effect was found in self-reported eating habits (p = .55). CONCLUSION Shared medical appointments are feasible in people with haemophilia and appear to improve physical activity. The effect on improving eating habits could not be established. Scientific replication of our approach is warranted to confirm or refute the merit of SMAs in people with haemophilia.

Abstract
Background Hemophilic ankle arthropathy is manifested by degenerative functional alterations and chronic pain. Myofascial release techniques are used to treat soft tissue adhesions, relieve pain, and reduce tissue sensitivity. Objective This study aims to evaluate the safety and efficacy of a protocol using self-myofascial release with a foam roller to be applied in patients with hemophilic ankle arthropathy. Methods Patients with ankle arthropathy (N=70) will be recruited, enrolled, and assigned to one of two groups—experimental or control—in a 1:1 allocation ratio. Patients will be recruited from 5 centers in different regions of Spain. Patient data will be collected at baseline, posttreatment, and follow-up. The primary outcome will be frequency of ankle joint bleeding (self-reported). The secondary outcomes will be ankle range of motion (measured with a digital goniometer); joint pain (measured with a visual analog scale and an algometer); joint status (measured using the Hemophilia Joint Health Score); muscle strength (measured with a dynamometer); functionality of lower limbs (measured using the 6-minute walking test); activity (self-reported); and muscle flexibility (measured using the fingertip-to-floor test). The treatment program includes 11 exercises that must be administered bilaterally. A mobile app will be developed where each patient will be able to observe the exercises to be carried out. Each session will last 15 minutes with 5 physiotherapy sessions per week for a period of 3 months. It is expected that patients with hemophilia who receive the foam roller intervention will show improvement in mobility, pain, and status of the ankle joint; muscle strength; and function in the lower extremities. Results The study has been approved by the institutional review board of the University of Murcia. Patient recruitment will begin in September 2020, and the intervention period will last until June 2021. Data collection will take place between September 2020 and October 2021. Conclusions This protocol describes a randomized clinical trial to examine the safety and efficacy of a self-myofascial release intervention using a foam roller in patients with hemophilic ankle arthropathy.

Abstract
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.

Abstract
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.

Abdulaziz JS, Hassan MK. Nutritional status of children and adolescents with haemophilia in Basra, Iraq. Haemophilia 2019; 25:e353-e360. [PMID: 31436002 DOI: 10.1111/hae.13837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2018] [Revised: 07/23/2019] [Accepted: 07/25/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Patients with haemophilia are at increased risk of being overweight or obese, which in turn may have a profound effect on morbidity and quality of life. AIMS To assess the nutritional status of paediatric patients with haemophilia and identify possible risk factors that may adversely affect their nutritional status. METHODS A case-control study was performed on 63 haemophilia patients and 135 control subjects aged 5-18 years. For all participants, weight, height and body mass index Z (BMIZ) score were assessed. Physical activity (PA) was assessed using the International Physical Activity Questionnaire and the Children's Physical Activity Questionnaire for participants ≥15 years and 5-14 years old, respectively. RESULTS The frequency of overweight and obesity was 36.29% among the control group compared with 23.81% among patients, while thinness was higher in patients with haemophilia (19.05%) compared with 9.63% in the control group, P = .042. Low PA was reported in 22.73% of haemophilia patients aged 5-14 years compared with 2.06% in the control group, P < .001. However, no difference in PA was reported among participants aged ≥15 years. There were no significant differences in the frequency of nutritional problems among patients with respect to age, type of haemophilia, disease severity and hepatitis C seropositivity. Regression analysis revealed a negative association between paternal educational level and high BMIZ in patients ≥15 years, P = .028. CONCLUSIONS Paediatric patients seem to have lower BMIZ than the control group. In addition, most of the studied factors were not found to predict either high or low BMIZ among studied patients.

Abstract
Frequently, pediatric hematologists need to provide guidance regarding sports participation for children with congenital coagulopathies, immune thrombocytopenia, and those receiving anticoagulation. Although sports participation has clear health and psychosocial benefits, it can be associated with harm secondary to bleeding from injury. Decision-making for sports involvement should be individualized, patient centered, and well informed. This review focuses on the current data regarding the benefit as well as risks for sports participation and provides a framework for advising and supporting the student athlete who is at risk for bleeding.

Obesity in the global haemophilia population: prevalence, implications and expert opinions for weight management. Obes Rev 2018; 19:1569-1584.

Abstract
Overweight and obesity may carry a significant disease burden for patients with haemophilia (PWH), who experience reduced mobility due to joint inflammation, muscle dysfunction and haemophilic arthropathy. This review aimed to define the prevalence and clinical impact of overweight/obesity in the global population of PWH. A detailed literature search pertaining to overweight/obesity in haemophilia in the last 15 years (2003-2018) was conducted, followed by a meta-analysis of epidemiological data. The estimated pooled prevalence of overweight/obesity in European and North American PWH was 31%. Excess weight in PWH is associated with a decreased range in motion of joints, accelerated loss of joint mobility and increase in chronic pain. Additionally, the cumulative disease burden of obesity and haemophilia may impact the requirement for joint surgery, occurrence of perioperative complications and the prevalence of anxiety and depression that associates with chronic illness. Best practice guidelines for obesity prevention and weight management, based on multidisciplinary expert perspectives, are considered for adult and paediatric PWH. Recommendations in the haemophilia context emphasize the importance of patient education and tailoring engagement in physical activity to avoid the risk of traumatic bleeding.

Abstract
SummaryThis study investigated the impact of aerobic exercise on laboratory assessments of haemostatic activity in boys (5–18 years of age) with haemophilia A (HA) or B (HB), examining the hypothesis that laboratory coagulation parameters temporarily improve with exercise. Thirty subjects meeting eligibility criteria (19 HA; 11 HB; mean age: 12.8 years) were invited to participate. They underwent a replacement factor washout period and were advised against strenuous activity for three days prior to the planned intervention. At study visit, baseline blood samples were drawn prior to exercise on a stationary cycle ergometer, aiming to attain 3 minutes (min) of cycling at 85 % of predicted maximum heart rate. Blood work was repeated 5 min (t5) and 60 min (t60) post exercise completion. Samples were assessed for platelet count (PC), factor VIII activity (FVIII:C), von Willebrand antigen (VWF:Ag), ristocetin cofactor activity (VWF:RCo) and platelet function analysis (PFA-100); maximum rate of thrombus generation (MRTG) in blood was measured via thromboelastography and plasma peak thrombin generation (PTG) via calibrated automated thrombography. Mean duration of exercise was 13.9 (± 2.6) min. On average, t5 samples showed significant elevation, relative to baseline in PC, FVIII:C, VWF:Ag, VWF:RCo and PTG, while FVIII:C, VWF:Ag, VWF:RCo and MRTG were significantly elevated in t60 samples. Within the cohort, participants with severe HA showed no change in FVIII:C levels with exercise. The greatest improvement in haemostatic indices was observed in post-adolescent males with mild-moderate HA, who thus represent the group most likely to benefit from a reduction of bleeding risk in the setting of exercise.

Abstract
The 6(th) Haemophilia Global Summit was held in Prague, Czech Republic, in September 2015. The programme was designed by an independent Scientific Steering Committee of haemophilia experts and aimed to share optimal management strategies for haemophilia at all life stages, explore recent potential advances in the management of haemophilia A and B and discuss challenges in haemophilia care. In this supplement from the meeting, Dan Hart reviews the lessons that can be learnt from cost-constrained environments with regard to improving care for people with haemophilia globally. Sébastien Lobet discusses the importance of physical activity for optimising care and Roseline d'Oiron and Jan Blatný consider the role of real-world data in understanding the effect of treatment in a clinical setting over the long term and the true impact of treatment on the day-to-day life of the patient. Gili Kenet addresses the current challenges relating to the optimal management of prophylaxis, and Gerry Dolan and Cedric Hermans discuss the value of pharmacokinetic (PK) parameters in informing treatment decisions. Cedric Hermans and Valérie Libotte explore the importance of considering social and occupational development factors as an integral part of haemophilia care, and Jan Astermark reviews key strategies to predict and prevent inhibitor development.

Abstract
The haemophilia treatment centre of the Clinic for Children and Youth Medicine in Jena extends medical care by health-promotion measures, namely: health counselling, adjuvant exercise therapy and school sports. In addition to the regular medical checks at the treatment centre patients are examined regarding physical fitness, joint situation, quality of life in general and disease-specific manner, as well as psycho-social and nutritional behaviour. Findings and medical results of the examinations are integrated into an individual advice on therapy, school sports, and health recommendations. This aimed at strengthening health-related resources and minimizing potential injuries. First long-term evaluation shows an increase of activity behaviour and physical fitness without increasing bleeding rate and maintained joint function. CONCLUSION Combining functional prevention diagnostics and individual health counselling shows signs of improved patient's health knowledge, self-competence and physical fitness.

Abstract
INTRODUCTION The World Federation of Haemophilia recommends joint and muscle health is evaluated using X-ray and magnetic resonance imaging, together with clinical examination scores. To date, inclusion of performance-based functional activities to monitor children with the condition has received little attention. AIM To evaluate test-retest repeatability of physical function tests and quantify relationships between physical function, lower limb muscle strength and gait patterns in young boys with haemophilia. METHODS Timed 6-minute walk, timed up and down stairs, timed single leg stance, muscle strength of the knee extensors, ankle dorsi and plantar flexors, together with joint biomechanics during level walking were collected from 21 boys aged 6-12 years with severe haemophilia. RESULTS Measures of physical function and recording of muscle strength with a hand-held myometer were repeatable (ICC > 0.78). Distances walked in six minutes, time taken to go up and down a flight of stairs and lower limb muscle strength correlated closely with ankle range of motion, together with peak knee flexion and ankle dorsi and plantarflexion moments during walking (P < 0.05). CONCLUSION Alterations in gait patterns of boys with haemophilia appear to be associated with changes in performance of physical function and performance seems to depend on their muscle strength. Timed 6-minute walk test, timed up and down steps test and muscle strength of the knee extensors showed the strongest correlation with biomechanical joint function, and hence might serve as a basis for the clinical monitoring of physical function outcomes in children with haemophilia.

Abstract
PURPOSE The present work aims to describe the psychometric field testing of the Latin American Hemophilia-Specific Quality of Life Assessment Measure for Adults (the HemoLatin-QoL questionnaire) in 306 adults (age range 16-80) with haemophilia living in seven Latin American countries (i.e. Argentina, Brasil, Chile, Nicaragua, Panama, Uruguay and Venezuela). METHODS The HemoLatin-QoL questionnaire is a patient-reported outcomes instrument that evaluates relevant health-related quality-of-life domains for haemophilia, selected by an exploratory qualitative study with patients, and taking into account healthcare specialists in haemophilia also. Psychometric examination involved the assessment of the data quality, scaling assumptions, reliability (internal consistency and test-retest) and evidences for validity (dimensionality, convergent and external-related clinical criterion). RESULTS A 27-item version with a six-factor structure (e.g. physical functioning, pain, emotional functioning, social functioning, mental health, environment conditions) was psychometrically tested using exploratory factor analysis. The instrument and its subscales fulfilled the construct (dimensionality, convergent and criterion-related) validity hypotheses. The criteria for adequate internal consistency and test-retest reliability of the HemoLatin-QoL instrument were also met. CONCLUSION The HemoLatin-QoL showed acceptable psychometric properties with respect to responses from haemophilia patients. The questionnaire is now available for adult assessment and is ready for use in research in Latin America.

Abstract
Hemophilia is a bleeding disorder caused by a congenital abnormality of blood coagulation. Until the mid-1970s, patients with hemophilia (PWH) were advised to refrain from physical activity (PA) because of a perceived increased risk of bleeding. Since then, PA, which is recognized as being essential for health maintenance, is now recommended by the World Federation of Hemophilia. Moreover, a number of studies reported that PA can improve treatment efficacy and prevent bleeding in PWH. Physical assessment and intervention in PA are currently used in clinical practice. However, the necessity of PA is not emphasized, and many PWH generally have low- to- no PA. Therefore, a behavior change approach to encourage patient motivation is becoming ever more important. In this article, we review articles addressing PA in PWH and discuss strategies to encourage PA through a behavior change approach by focusing on factors relevant to hemophilia, such as benefits and bleeding risk of PA, risk management of bleeding, PA characteristics, and difficulty with exercise adherence. The trust relationship between clinicians and patients, a transtheoretical model of behavior change, and motivation theory as approaches to promote PA are introduced. Finally, we review a case report of the clinical success of a behavior change approach to promote PA. Many PWH find it difficult to continue PA because of aging, fear of bleeding, insufficient recognition of PA benefits, and psychological problems. Therefore, it is essential and important to perform prophylaxis with PWH and to heighten their understanding of the benefits and risks of PA, before initiating the exercise regimen. For those patients who find it difficult to participate in PA, it is necessary to plan individual-based behavior change approach and encourage self-efficacy.

Abstract
Prophylaxis has become the standard mantra of care for those individuals with severe haemophilia A and B. Primary prophylaxis is advocated to prevent the occurrence of symptomatic acute spontaneous haemarthroses and to preserve joint structure and function. Typically, twice or thrice weekly infusions of factor VIII or IX concentrates are integral to this treatment approach. Secondary prophylaxis is initiated after the relentless cycle of progressive joint damage has been triggered by prior haemarthroses and is intended to preserve existing joint health by preventing additional spontaneous bleeding events. Event-driven prophylaxis involves the administration of clotting factor concentrates to prevent acute traumatic bleeds, which are anticipated to occur in association with surgical or physical trauma. This regimen enhances the effectiveness of primary or secondary prophylaxis protocols or on-demand approaches to replacement therapy. Besides the marked reduction in the so-called annual bleed rate, prophylaxis regimens frequently increase personal self-confidence to embark on a more active and physical lifestyle; however, in reality, prophylaxis must be individualized in accordance with bleeding phenotypes, with the unique pharmacokinetic profile of administered replacement clotting factor concentrates, with the specific clinical scenario, and with the degree of intensity anticipated for any physical activity. The introduction of extended half-life replacement products will also influence how these prophylaxis regimens will be accomplished. The following scenarios will discuss how prophylaxis regimens can be implemented to protect the individual from developing spontaneous and activity-induced acute bleeding complications and to maintain an improved quality of life.

Abstract
Our objective was to provide a synthesis of measurement properties for performance-based outcome measures used to evaluate physical function in children with haemophilia. A systematic review of articles published in English using Medline, PEDro, Cinahl and The Cochrane Library electronic databases was conducted. Studies were included if a performance-based method, clinical evaluation or measurement tool was used to record an aspect of physical function in patients with haemophilia aged ≤ 18 years. Recording of self-perceived or patient-reported physical performance, abstracts, unpublished reports, case series reports and studies where the outcome measure was not documented or cross-referenced was excluded. Description of outcome measures, patient characteristics, measurement properties for construct validity, internal consistency, repeatability, responsiveness and feasibility was extracted. Data synthesis of 41 studies evaluating 14 measures is reported. None of the outcome measures demonstrated the requirements for all the measurement properties. Data on validity and test-retest repeatability were most lacking together with studies of sufficient size. Measurement of walking and muscle strength demonstrated good repeatability and discriminative properties; however, correlation with other measures of musculoskeletal impairment requires investigation. The Haemophilia Joint Health Score demonstrated acceptable construct validity, internal consistency and repeatability, but the ability to discriminate changes in physical function is still to be determined. Rigorous evaluation of the measurement properties of performance-based outcome measures used to monitor physical function of children with haemophilia in larger collaborative studies is required.

Abstract
BACKGROUND The Six-Minute Walk Test (6MWT) is increasingly being used as a functional outcome measure for chronic pediatric conditions. Knowledge about its measurement properties is needed to determine whether it is an appropriate test to use. PURPOSE The purpose of this study was to systematically review all published clinimetric studies on the 6MWT in chronic pediatric conditions. DATA SOURCES The databases MEDLINE, EMBASE, CINAHL, PEDro, and SPORTDiscus were searched up to February 2012. STUDY SELECTION Studies designed to evaluate measurement properties of the 6MWT in a chronic pediatric condition were included in the systematic review. DATA EXTRACTION The methodological quality of the included studies and the measurement properties of the 6MWT were examined. DATA SYNTHESIS A best evidence synthesis was performed on 15 studies, including 9 different chronic pediatric conditions. Limited evidence to strong evidence was found for reliability in various chronic conditions. Strong evidence was found for positive criterion validity of the 6MWT with peak oxygen uptake in some populations, but negative criterion validity was found in other populations. Construct validity remained unclear in most patient groups because of methodological flaws. Little evidence was available for responsiveness and measurement error. Studies showed large variability in test procedures despite existing guidelines for the performance of the 6MWT. LIMITATIONS Unavailability of a specific checklist to evaluate the methodological quality of clinimetric studies on performance measures was a limitation of the study. CONCLUSIONS Evidence for measurement properties of the 6MWT varies largely among chronic pediatric conditions. Further research is needed in all patient groups to explore the ability of the 6MWT to measure significant and clinically important changes. Until then, changes measured with the 6MWT should be interpreted with caution. Future studies or consensus regarding modified test procedures in the pediatric population is recommended.

Abstract
Intermittent joint bleeding and potential arthropathy remain a concern for patients and those responsible for haemophilic care. Monitoring the status of haemophilic joints is a current challenge. Evaluation of bone and soft tissue with radiological imaging together with clinical joint scoring is often used to monitor haemophilic arthropathy and may not be sufficiently sensitive to early changes in joint morphology. Recently an interest in the biomechanical status of haemophilic joints has emerged. Biomechanics is defined as the interdiscipline that describes, analyses and assesses movement in relation to biological and physical principles. This review considers the biomechanical evaluation of haemophilic joint status of the lower limb with particular reference to the evaluation of muscle atrophy, muscle strength, range of motion and gait as well as the relationship to haemophilic arthropathy. In raising the need for increased clinical awareness, this review highlights the need to establish test-retest and inter-rater reliability and ensuring that comparative studies are undertaken with age-matched unaffected peer groups.

Abstract
CONTEXT As life expectancy in individuals with congenital hemophilia approaches that of the general population, we hypothesize that public health risks, including overweight and obesity, also follow a similar trend. EVIDENCE ACQUISITION A search of the literature included terms relating to overweight, sequelae of being overweight, and hemophilia. Studies were included if they reported the frequency or clinical significance of known complications of overweight and obesity, including musculoskeletal disease, aerobic capacity, cardiovascular disease, diabetes, hyperlipidemia, decreased quality of life, and change in pharmacokinetics of infused clotting factor in hemophilia. Recommendations from medical organizations were searched for preventive and management strategies applicable to this population. EVIDENCE SYNTHESIS Overweight and obesity are now more prevalent in the hemophilia population than previous generations, with rates similar to and, in certain subsets even higher, than that of the general population. Increased BMI leads to limitations in joint range of motion in the general population and even more so in persons with hemophilia. CONCLUSIONS Overweight and obesity in hemophilia are an increasing problem. Simple steps can be taken to encourage patients to decrease caloric intake and increase physical activity. Prevention and management of overweight, obesity, and their sequelae must be addressed in clinical practice in order to maximize the overall health of the hemophilia population.
