Summary.  In recent studies, adolescent haemophilia A patients and healthy adolescents have been encouraged to participate in physical activity (PA) based on its many established health benefits. However, none of the studies to date has used objective measures of PA and sedentary behaviour. The aims of the current study included: (i) to determine the amount and intensity of habitual PA among haemophilia A and healthy adolescents, and in haemophilia A patients with and without bleeding episodes in the previous year, and (ii) to identify the type and determine the time spent in sedentary activities in which both groups participate to obtain a broadened view of their daily activities. A total of 41 adolescent haemophiliacs and 25 healthy adolescents, between the ages of 8 and 18 years, participated in this cross‐sectional study. A triaxial accelerometer was used to measure PA and the Adolescent Sedentary Activity Questionnaire to assess sedentary behaviours among members of both groups. Adolescent haemophilia A patients showed a higher daily mean time engaged in light, moderate and moderate‐to‐vigorous PAs relative to their healthy counterparts (P < 0.001). Patients who had experienced bleeding episodes during the previous year also spent more time participating in vigorous PAs than healthy adolescents (P = 0.002). With regard to sedentary behaviours, healthy adolescents spent more time listening to music than haemophilia A adolescents (P = 0.003), whereas haemophilia A adolescents spent more time watching TV (P < 0.001) and playing videogames (P = 0.003) than healthy counterparts. Findings suggest that increased participation in moderate intensity PAs and reduced sedentary behaviours should be recommended among adolescents with haemophilia A.

Alterations in the musculoskeletal system, especially in the lower limbs, limit physical activity and affect balance and walking. Postural impairments in haemophilic preteens could increase the risk of bleeding events and deteriorate the physical condition, promoting the progression of haemophilic arthropathy.

Introduction: Sports activities are part of multidisciplinary treatments in people with hemophilia. Aim: The objective of this study was to assess the incidence of sports activities in the quality of life as perceived by children with hemophilia. Methods: A total of 53 children with hemophilia aged 7 to 13 years and 51 children without hemophilia were evaluated. The perception of quality of life, clinical variables, and the frequency of sports activities were registered. The joint condition of patients with hemophilia was measured with the Spanish version of the Haemophilia Joint Health Score. Results: There were no significant differences in the perception of quality of life between children with hemophilia and children without hemophilia. Sports activities in people with hemophilia promoted a greater health satisfaction. Conclusions: Sports activity in children with hemophilia is associated with an improved quality of life and joint health. It is also associated with improved psychosocial wellness.

HemoKinect: A Microsoft Kinect V2 Based Exergaming Software to Supervise Physical Exercise of Patients with Hemophilia

Fernando Mateo; Emilio Soria-Olivas; Juan José Carrasco; Santiago Bonanad; F. Querol; S. Pérez-Alenda

Patients with hemophilia need to strictly follow exercise routines to minimize their risk of suffering bleeding in joints, known as hemarthrosis. This paper introduces and validates a new exergaming software tool called HemoKinect that intends to keep track of exercises using Microsoft Kinect V2’s body tracking capabilities. The software has been developed in C++ and MATLAB. The Kinect SDK V2.0 libraries have been used to obtain 3D joint positions from the Kinect color and depth sensors. Performing angle calculations and center-of-mass (COM) estimations using these joint positions, HemoKinect can evaluate the following exercises: elbow flexion/extension, knee flexion/extension (squat), step climb (ankle exercise) and multi-directional balance based on COM. The software generates reports and progress graphs and is able to directly send the results to the physician via email. Exercises have been validated with 10 controls and eight patients. HemoKinect successfully registered elbow and knee exercises, while displaying real-time joint angle measurements. Additionally, steps were successfully counted in up to 78% of the cases. Regarding balance, differences were found in the scores according to the difficulty level and direction. HemoKinect supposes a significant leap forward in terms of exergaming applicability to rehabilitation of patients with hemophilia, allowing remote supervision.

Background: In the university context, assessing students’ attitude, knowledge and opinions when applying an innovative methodological approach to teach professional ethics becomes fundamental to know if the used approach is enough motivating for students. Research objective: To assess the effect of a blended-learning model, based on professional ethics and related to clinical practices, on physiotherapy students’ attitude, knowledge and opinions towards learning professional ethics. Research design and participants: A simple-blind clinical trial was performed (NLM identifier NCT03241693) (control group, n = 64; experimental group, n = 65). Both groups followed clinical practices for 8 months. Control group performed a public exposition of a clinical case about professional ethics. By contrast, an 8-month blended-learning programme regarding professional ethics was worked out for experimental group. An online syllabus and online activities were elaborated, while face-to-face active participation techniques were performed to discuss ethical issues. Students’ attitudes, knowledge and opinions towards learning professional ethics were assessed. Ethical considerations: The study was approved by the University Ethic Committee of Human Research and followed the ethical principles according to the Declaration of Helsinki. Findings: After the programme, attitudes and knowledge towards learning professional ethics of experimental group students significantly improved, while no differences were observed in control group. Moreover, opinions reported an adequate extension of themes and temporization, importance of clinical practices and interest of topics. Case study method and role playing were considered as the most helpful techniques. Conclusion: The blended-learning programme proposed, based on professional ethics and related to clinical practices, improves physiotherapy students’ attitudes, knowledge and opinions towards learning professional ethics.

Context: Spasticity in neurological disorders (i.e. stroke patients and cerebral palsy) is positively improved by dry needling. However, reports are scarce regarding the potential effects of dry needling in reducing spasticity and improving functionality in patients with an incomplete spinal cord injury. The aim of this case report was to study the immediate, short-term effects of dry needling treatment (10 weeks) on spasticity, dynamic stability, walking velocity, self-independence, and pain in a single patient with an incomplete spinal cord injury. Findings: The dry needling treatment resulted in immediate, short-time effects on basal spasticity in the upper (reduction from 2 to 0 point median) and lower (reduction from 2 to 0 point median) limbs, as measured by the modified Ashworth Scale. Dynamic-stability, assessed by trunk accelerometry, improved more than 50% (Root Mean Squared of acceleration, Root Mean Squared of Jerk and step variability), and gait speed improved by 24.7 s (i.e. time to walk 20 m). Self-independence and pain were respectively scored by the Spinal Cord Independence Measure (21 points improvement) and visual analog scale (4 points improvement). Conclusions: This case report demonstrates that dry needling treatment can have positive effects on spasticity, dynamic stability, walking velocity, self-independence, and pain in patients with incomplete spinal cord injury. Further research is needed in a larger patient population to deeply understand the mechanism(s) associated with the obtained results and regarding the clinical significances of dry needling treatment for incomplete spinal cord injury.

Effect of radiosynoviorthesis on the progression of arthropathy and haemarthrosis reduction in haemophilic patients

M. Querol-Giner; S. Pérez-Alenda; M. Aguilar-Rodríguez; Juan José Carrasco; Santiago Bonanad; F. Querol

Repeated haemarthrosis is widely accepted as the triggering cause of synovitis and haemophilic arthropathy. A first‐line treatment of chronic synovitis is radiosynoviorthesis (RS). The aim of this study was to evaluate the RS effects on the progression of arthropathy and on a reduction in bleeding in patients with haemophilia.
