A novel passive neck orthosis for patients with degenerative muscle diseases: Development & evaluation.

The current study evaluated the effect of a passive neck orthosis, developed for patients suffering from progressive muscular diseases, on neck muscle activity in 10 adult healthy participants. The participants performed discrete head movements involving pure neck flexion (-10 to 30°), pure neck rotation (up to 30° left and right) and combined neck flexion-rotation (-10 to 30°) in steps of 10° by moving a cursor on a screen to reach predefined targets and staying on target for 10 s. Surface electromyography (EMG) was recorded from upper trapezius and sternocleidomastoid muscles and amplitudes were averaged over the static phases in trials with and without the orthosis. Moreover, the variability in head position and time required to perform the tasks were compared between conditions. Wearing the orthosis caused significant reductions (p = 0.027) in upper trapezius activity (a change of 0.2-1.5% EMGmax) while working against gravity. The activity level of the sternocleidomastoid muscle increased (p ≤ 0.025) by 0.3-1.0% EMGmax during pure and combined rotations without any pain reported. The orthosis showed potential to reduce the activity level of the upper trapezius muscle, the main load bearing muscle of the neck. Further study will be carried out to evaluate the effect in different patient groups.

Use and Cost of Orthosis in Conservative Treatment of Acute Thoracolumbar Fractures: A Survey of European and North American Experts.

STUDY DESIGN: Survey study. OBJECTIVE: Assess practices and opinions of spine specialists from Europe and North America on orthosis use in adult patients with acute thoracolumbar (TL) fractures. Evaluate cost of the devices. SUMMARY OF BACKGROUND DATA: Although orthosis are traditionally used in conservative treatment of TL fractures, recent systematic reviews showed no benefit in patient's outcomes. METHODS: A search for contact authors with publications on spine fractures from all European and North American countries was performed. An online questionnaire was sent on demographic data, practice setting, mean number of fractures treated, use of orthosis upon choice for conservative treatment, and average orthosis cost. Data was analyzed based in world regions, economic rank of the country, and health expenditure. RESULTS: We received 130 answers, from 28 European and five North American countries. Most responders had more than 9 years of practice and worked at a public hospital. 6.2% did not prescribe a brace in any patient with acute TL fractures conservatively treated and 11.5% brace all patients. In a scale from 1 to 5, 21 considered that there is no/low benefit (1) and 14 that bracing is essential (5), with a mean of 3.18. Europeans use orthosis less commonly than North Americans (P < 0.05). Orthosis mean cost was $611.4 ±â€Š716.0, significantly higher in North America compared with Europe and in high income, when compared with upper middle income countries (both P < 0.05). Although hospital costs were not evaluated, orthosis is costlier when it involves admission of the patient (P < 0.05). An increase in orthosis cost associated with higher gross domestic product (GDP) per capita and higher health expenditure was found. CONCLUSION: More than 90% of spine specialists still use orthosis in conservative treatment of adult patients with acute TL fractures. Orthosis cost vary significantly between continents, and it is influenced by the country's economy.Level of Evidence: 4.

Prosthetists and orthotists: An evolution from mechanic to clinician.

Fifty years ago, the International Society for Prosthetics and Orthotics was founded in recognition that this unique niche in rehabilitation would benefit from multidisciplinary interactions between specialists in engineering, therapy, and medicine.Since then, field evolved from having a craft orientation toward a technology and clinical specialty. This anniversary provides an opportunity to look back on advances in prosthetics and orthotics, and the clear impact they have had on changing the skills needed by the prosthetist/orthotist as new technology and techniques have emerged. The balance has clearly shifted from mechanical skills to clinical care. The training and skills of the prosthetist/orthotist remain unique and valued in the rehabilitation team, and the primary motivation remains the same as it has been since the creation of the International Society for Prosthetics and Orthotics: the application of external devices where they are suitable to address the many varied needs of persons with disability. This historical perspective puts into context why and how the profession has changed, while also reinforcing that it is the goals set for restoring patient functions that best defines what it is to be a prosthetist/orthotist, not the means we use.

Physical sciences.

In the original edition of Prosthetics and Orthotics International, Dr Sidney Fishman identified what he anticipated as foundational educational needs for the emerging field of clinical prosthetics and orthotics. Within the broader construct of the physical sciences, this included mathematics, physics, chemistry, biomechanics, and material sciences. The clinical application of these disciplines to expanding the collective understanding within the field is described, including the biomechanics of able-bodied and prosthetic gait, the material science of socket construction, the physics of suspension and load distribution, and the engineering of prosthetic components to mimic human biomechanics. Additional applications of the physical sciences to upper limb prosthetics and lower limb orthotics are also described. In contemplating the continued growth and maturation of the field in the years to come, mechatronics and statistics are suggested as future areas where clinical proficiency will be required.

Education in prosthetic and orthotic training: Looking back 50 years and moving forward.

There is a long history of prosthetic and orthotic services helping to mitigate the impact of physical impairment by restoring function, and enabling and equipping the user. The training of health professionals who design, fit, and maintain prosthetic and orthotic devices has evolved over the centuries, reflecting an increase in knowledge, technology, understanding, and social attitudes in each era. Improvements in pedagogical thinking and biomechanical understanding, as well as the advent of new integrated technologies, have driven the profession over the past 50 years to modernize, evolve training and service delivery models in line with new attitudes toward clients, and search for new ways to improve users' quality of life. In this narrative review, the authors examined the evolution of prosthetic and orthotic education, the impact of changing educational techniques and technologies, and the impact of the International Society for Prosthetics and Orthotics in that process. Through conversations with experts and review of peer-reviewed literature, accreditation documents, and the International Society for Prosthetics and Orthotics records and databases, the authors identified three areas of change in prosthetics and orthotics education over the past 50 years: (1) prosthetic/orthotic curriculum content, (2) pedagogy and course delivery, and (3) internships/residencies. This narrative review is a snapshot of a growing profession and we can only speculate where the next 50 years will lead us as we strive to serve patients, ever placing their needs and aspirations at the center of this professional service.

A toolkit for prosthetists and orthotists to facilitate progress in professional communication over the next 50 years.

BACKGROUND: In this celebratory issue of Prosthetics and Orthotics International, we review professional communication skills in the field of prosthetics and orthotics. OBJECTIVE: We aim to reflect on communication skills in the past 50 years, to discuss developments in the coming 50 years, and to create a toolkit and research agenda to facilitate progress in professional communication in the next 50 years. RESULTS: Despite being a key area in prosthetics and orthotics training programmes, we found no studies on professional communication with an experimental design published in Prosthetics and Orthotics International. As an alternative, we provide clinical reflections on the changes in professional communication in the past 50 years, and we discuss questionnaire-based and qualitative studies that provide evidence for the importance of communication in pedorthic footwear provision. In the coming 50 years, professional communication in the field of prosthetics and orthotics may be impacted by aging populations, global mobility, information technology, technological advances and emphasis on prevention. We discuss each of these topics. To facilitate progress in professional communication, we have created a toolkit with resources for prosthetics and orthotics professionals, prosthetics and orthotics students and other interested professionals. CONCLUSIONS: We hope this toolkit will inspire others to use, extend and implement it in their daily practice. As a research agenda, we strongly recommend undertaking research on interventions to improve professional communication and to study its effect on clinically meaningful outcomes.

Basal thumb arthritis: Treatment strategies for managing pain.

BACKGROUND: The carpometacarpal joint of the thumb is one of the joints most commonly affected by arthritis. The dominant hand is involved in 60-65% of cases, with a higher prevalence among women. The condition results in significant disability of the hand, which affects activities of daily living. Management is dependent on both the clinical stage of the disease and patient expectations and demands. OBJECTIVE: The aim of this article is to review the current non-operative and operative modalities in managing pain symptoms, and explore evidence for the use of these modalities. DISCUSSION: Basal thumb arthritis is a very common condition encountered by the general practitioner. Treatment must focus on functional expectations and demands of the patient, and individualised treatment plans need to be tailored to the patient. Hand therapy in addition to patient education and use of an orthosis has been shown to be very effective in management of the early stages of basal thumb arthritis. With more advanced disease, surgical modalities provide better symptomatic control.

Orthosis in Thoracolumbar Fractures: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

STUDY DESIGN: Systematic review and meta-analysis of randomized controlled trial (RCT). OBJECTIVE: The aim of this study was to evaluate radiological and clinical outcomes of acute traumatic thoracolumbar fractures in skeletally mature patients treated with orthosis, versus no immobilization. SUMMARY OF BACKGROUND DATA: Orthosis is traditionally used in conservative treatment of thoracolumbar fractures. However, recent studies suggest no benefit, and a possible negative impact in recovery. METHODS: Databases were searched from inception to June 2019. Studies were selected in two phases by two blinded reviewers; disagreements were solved by consensus. Inclusion criteria were: RCT; only patients with acute traumatic thoracolumbar fractures; primary conservative treatment; comparison between orthosis and no orthosis. Exclusion criteria were inclusion of nonacute fractures, patients with other significant known diseases and comparison of groups different than use of an orthosis. Two independent reviewers performed data extraction and quality assessment. Fixed-effects models were used upon no heterogeneity, and random-effects model in the remaining cases. A previous plan for extraction of radiological (kyphosis progression; loss of anterior height) and clinical (pain; disability; length of stay) outcomes was applied. PRISMA guidelines were followed. RESULTS: Eight articles/five studies were included (267 participants). None reported significant differences in pain, kyphosis progression, and loss of anterior height. One reported a better ODI with orthosis at 12 but not at 24 weeks. No other study reported differences in disability. All authors concluded an equivalence between treatments.Meta-analysis showed a significant increase of 3.47days (95% confidence interval 1.35-5.60) in mean admission time in orthosis group. No differences were found in kyphosis at 6 and 12 months; kyphosis progression between 0 to 6 and 0 to 12 months; loss of anterior height 0 to 6 months; VAS for pain at 6 months; VAS change 0 to 6 months. CONCLUSION: Orthosis seems to add no benefit in conservative treatment of acute thoracolumbar fractures. This should be considered in guidelines and reviews of health care policies. LEVEL OF EVIDENCE: 3.

How shoulder immobilization influences daily physical activity - an accelerometer based preliminary study.

BACKGROUND: To investigate the influence of shoulder immobilization on daily physical activity. INTRODUCTION: The harmful effect of sedentary behavior does not receive much attention in orthopedic surgery even though immobilization, especially of the lower extremity, has been associated with reduced physical activity. Immobilization of the shoulder is common after reconstructive shoulder surgery and could also potentially lead to reduced physical activity and have a negative effect on a patient's general health. METHOD: Twenty-one healthy volunteers were immobilized in an orthosis (DJO Ultrasling III) for 10 h on two consecutive days. In the following week, activity was measured on the same days without the orthosis. Activity including gait cycles per minute and total gait cycles per day was measured by accelerometer based step count StepWatchTMActivity Monitor. Average age was 26 +/- 3 years. A questionnaire was administered to evaluate subjective activity. RESULTS: Participants wearing the shoulder orthosis were significantly less active than without immobilization by 2227.5 gait cycles/day (5501.2 with SO, 7728.7 without SO). Also, significantly more time in sedentary behavior occurred (< 400 steps/h) when the shoulder was immobilized. Patients were significantly more active without shoulder orthosis in medium level activities (800-999 steps/h). Differences for low (400-799 steps/h) and high activity levels (> 1000 steps/h) were not statistically significant. Subjective limitations while wearing the orthosis were graded at 2.343 on a scale of 0-4. CONCLUSION: Results of this study show that even in young, healthy volunteers immobilization of the shoulder in an orthosis for 2 days leads to significantly reduced activity levels. A negative influence on general health, especially in older patients who are immobilized for up to 6 weeks, can potentially occur. Promoting physical activity during the immobilization period should be part of rehabilitation after injuries/surgery of the shoulder. TRIAL REGISTRATION: Retrospectively registered in DRKS (DRKS00017636).

Tremor Control Devices for Essential Tremor: A Systematic Literature Review.

Background: There is a growing interest in nonpharmacological approaches for essential tremor (ET), including tremor cancelation devices. However, the true efficacy of such devices in ET remains unclear. Methods: A systematic literature review was conducted using standardized criteria regarding efficacy and comfortability. Devices focused on design or experimental testing in which tremor was simulated in a robot were excluded. Results: Out of 324 articles initially identified, 12 articles were included. Orthoses using biomechanical loading and neuromodulation with electrical stimulation, and external tremor cancelation devices, were the main interventions used to suppress tremor. All devices were designed to control tremor of the upper limbs at different anatomical locations. Overall, an average tremor attenuation of 50-98% was reported (level of evidence III). Interference with voluntary movements and portability was described as the main drawback. Discussion: In conclusion, this review highlights the growing interest in emerging tremor control devices and the importance of assessing comfort without affecting voluntary movements. However, the level of evidence regarding the efficacy of these tremor control devices remains low. An integrated multidisciplinary combination approach of engineering, robotics, physiology, physiotherapy, and clinical assessment is needed to improve the quality of non-pharmacological interventions for ET.

An alternative to plaster cast treatment in a pediatric trauma center using the CAD/CAM technology to manufacture customized three-dimensional-printed orthoses in a totally hospital context: a feasibility study.

The aim of this study is to implement the clinical use of the three-dimensional (3D) design and printing technology in pediatric pathologies requiring immobilization. We describe the manufacturing process of the 3D device in place of the plaster cast usually applied to a child 48/72 h after the access to the Trauma Center Traumatology Hub. This procedure had already been performed at Level II, Trauma Center, Campania Region, Orthopaedic Division of Santobono Children's Hospital, Naples, Italy. The operative phase was performed by two 3D printers and a scanner in the bioengineering laboratory of the hospital's outpatient area. The phase of software elaboration requires close cooperation among physicians and engineers. We decided to use a model with a double-shell design and holes varying in width to ensure complete ventilation and lightness of the device. We chose to treat nondisplaced metaphyseal distal fractures of the radius in 18 patients enrolled from January 2017 to November 2017. The flow chart includes clinical and radiological examinations of every enrolled child, collecting information required by the program and its elaboration by bioengineers, and then transfer of the results to 3D printers. The child, immobilized by a temporary splint, wore his 3D device after 12/24 h. Then, he underwent serial check-ups in which the effectiveness and appropriateness of the treatment were clinically monitored and evaluated using subjective scales: visual analogue scale and patient-rated wrist evaluation. All the fractures consolidated both radiologically and clinically after the treatment, with no complications reported. Only one partial breakage of the device happened because of an accidental fall. The statistical analysis of the visual analogue scale and patient-rated wrist evaluation data shows that children's activities of everyday life improved during the immobilization thanks to this treatment. This first study shows that using a 3D device instead of a traditional plaster cast can be an effective alternative approach in the treatment of pediatric nondisplaced metaphyseal distal radius fractures, with high overall patient satisfaction. We believe that 3D technology could be extended to the treatment of more complex fractures; this will be the subject of our second study.

The influence of staff training and education on prosthetic and orthotic service quality: A scoping review.

BACKGROUND: Education and training in prosthetics and orthotics typically comply with International Society for Prosthetics and Orthotics standards based on three categories of prosthetic and orthotic professionals. OBJECTIVE: This scoping study sought to describe the evidence base available to answer the question, How are prosthetic and orthotic services influenced by the training of staff providing them? STUDY DESIGN: Scoping review. METHODS: A structured search of the peer-reviewed literature catalogued in major electronic databases yielded 3039 papers. Following review of title and abstract, 93 articles were considered relevant. Full-text review reduced this number to 25. RESULTS: Only two articles were identified as providing direct evidence of the effects of training and education on service provision. While both suggested that there was an impact, it is difficult to see how the more specific conclusions of either could be generalised. The other 23 articles provide a useful background to a range of issues including the specification of competencies that training programmes should deliver (3 articles), descriptions of a range of training programmes and the effects of training and education on student knowledge and skills. CONCLUSION: Although it is considered axiomatic, the service quality is dependent on practitioner education and training. There is insufficient evidence to establish whether levels of training and education in prosthetics and orthotics have an effect on the quality of prosthetic and orthotic services. Clinical relevance There is very little evidence about the effects of training and education of prosthetists and orthotists on service quality. While this is a somewhat negative finding, we feel that it is important to bring this to the attention of the prosthetics and orthotics community.

Validation and psychometric properties of the commitment to hip protectors (C-HiP) index in long-term care providers of British Columbia, Canada: a cross-sectional survey.

BACKGROUND: If worn during a fall, hip protectors substantially reduce risk for hip fracture. However, a major barrier to their clinical efficacy is poor user adherence. In long-term care, adherence likely depends on how committed care providers are to hip protectors, but empirical evidence is lacking due to the absence of a psychometrically valid assessment tool. METHODS: We conducted a cross-sectional survey in a convenience sample of 529 paid care providers. We developed the 15-item C-HiP Index to measure commitment, comprised of three subscales: affective, cognitive and behavioural. Responses were subjected to hierarchical factor analysis and internal consistency testing. Eleven experts rated the relevance and clarity of items on 4-point Likert scales. We performed simple linear regression to determine whether C-HiP Index scores were positively related to the question, "Do you think of yourself as a champion of hip protectors", rated on a 5-point Likert scale. We examined whether the C-HiP Index could differentiate respondents: (i) who were aware of a protected fall causing hip fracture from those who were unaware; (ii) who agreed in the existence of a champion of hip protectors within their home from those who didn't. RESULTS: Hierarchical factor analysis yielded two lower-order factors and a single higher-order factor, representing the overarching concept of commitment to hip protectors. Items from affective and cognitive subscales loaded highest on the first lower-order factor, while items from the behavioural subscale loaded highest on the second. We eliminated one item due to low factor matrix coefficients, and poor expert evaluation. The C-HiP Index had a Cronbach's alpha of 0.96. A one-unit increase in championing was associated with a 5.2-point (p < 0.01) increase in C-HiP Index score. Median C-HiP Index scores were 4.3-points lower (p < 0.01) among respondents aware of a protected fall causing hip fracture, and 7.0-points higher (p < 0.01) among respondents who agreed in the existence of a champion of hip protectors within their home. CONCLUSIONS: We offer evidence of the psychometric properties of the C-HiP Index. The development of a valid and reliable assessment tool is crucial to understanding the factors that govern adherence to hip protectors in long-term care.

The health belief model and factors associated with adherence to treatment recommendations for positional plagiocephaly.

OBJECTIVE This study aimed to examine factors associated with adherence to recommended treatment among pediatric patients with positional skull deformity by reviewing a single-institution experience (2007-2014) with the treatment of positional plagiocephaly. METHODS A retrospective chart review was conducted. Risk factors, treatment for positional head shape deformity, and parent-reported adherence were recorded. Univariate and multivariate analyses were used to assess the impact of patient clinical and demographic characteristics on adherence. RESULTS A total of 991 patients under age 12 months were evaluated for positional skull deformity at the Texas Children's Hospital Cranial Deformity Clinic between 2007 and 2014. According to an age- and risk factor-based treatment algorithm, patients were recommended for repositioning, physical therapy, or cranial orthosis therapy or crossover from repositioning/physical therapy into cranial orthosis therapy. The patients' average chronological age at presentation was 6.2 months; 69.3% were male. The majority were white (40.7%) or Hispanic (32.6%); 38.7% had commercial insurance and 37.9% had Medicaid. The most common initial recommended treatment was repositioning or physical therapy; 85.7% of patients were adherent to the initial recommended treatment. Univariate analysis showed differences in adherence rates among subgroups. Children's families with Medicaid were less likely to be adherent to treatment recommendations (adherence rate, 80.2%). Families with commercial insurance were more likely to be adherent to the recommended treatment (89.6%). Multivariate logistic regression confirmed that factors associated with parent-reported adherence to recommended treatment included primary insurance payer, diagnosis (plagiocephaly vs brachycephaly), and the nature of the recommended treatment. Families were less likely to be adherent if they had Medicaid, a child with a diagnosis of brachycephaly, or were initially recommended for cranial orthosis therapy than families with commercial insurance, a child with a diagnosis of plagiocephaly, or an initial recommendation for repositioning or physical therapy. Factors associated with treatment completion included corrected age, insurance, diagnosis, recommended treatment, and distance to provider from patient's residence. Patients with commercial insurance (OR 1.49, 95% CI 1.10-2.02, p = 0.009), those diagnosed with both brachycephaly and plagiocephaly (OR 2.26, 95% CI 1.31-3.90, p = 0.003), those recommended for treatment with cranial orthosis (OR 4.55, 95% CI = 3.24-6.38, p < 0.001), and those living in proximity to the provider (OR 1.40, 95% CI 1.00-1.96, p = 0.047) were more likely to complete treatment. CONCLUSIONS Insurance type, degree of head shape deformity, and types of recommended treatment appear to affect rates of adherence to recommended treatments for positional skull deformation.

También se encontraron diferencias significativas en la calidad de vida a favor del uso de órtesis (p<0,0005). Conclusiones. El uso de órtesis de compresión controlada en el postoperatorio inmediato de la cirugía conservadora de cáncer de mama reduce del 32 al 15% la incidencia conjunta de complicaciones posquirúrgicas y mejora en términos de eficacia, seguridad y comodidad al apósito compresivo habitual (AU)

Objectives. To compare the overall and individual incidence of postoperative complications, comfort and quality of life resulting from the use of compressive bandaging versus a specific controlled compression garment. Patients and method. A randomised controlled trial was conducted in 198 patients distributed in 2 groups: bandaging (n=88) and compression garment (n=99). Variables related to immediate postoperative complications and satisfaction with quality of life were collected. Changes in the variables were compared in the 2 groups during the first postoperative month. Results. The incidence of total complications was significantly lower with the compression garment: 7 days (P=.032) and 15 days (P=.009). Pain was significantly reduced with the compression garment: 7 days (P=.002) and 15 days (P=.012). The incidence of skin injury was also significantly reduced: 0-2% with the compression garment versus 35% with bandaging (P<0.0005). Significant differences were found in quality of life in favour of the use of the compression garment (P<0.0005). Conclusions. The use of a specific controlled compression garment in the immediate postoperative period after breast cancer-conserving surgery reduces the likelihood of postoperative complications from 32 to 15% and enhanced efficacy, safety, and patient comfort compared with the usual compressive dressing (AU)

Mejoría de la función cardio-respiratoria en paciente con circulación de fontán tras la intervención quirúrgica de su escoliosis / Improvement of the cardio-respiratory function in fontan patients after surgery of scoliosis

La escoliosis puede tener un impacto negativo sobre la función cardio-respiratoria en pacientes con cirugía de Fontán. Cuando las consecuencias de la progresión de la deformidad sobre la calidad de vida y la supervivencia potencial a largo plazo del paciente superan los riesgos de la intervención se aconseja el tratamiento quirúrgico de la curva. Desafortunadamente, este grupo de pacientes presenta un elevado riesgo anestésico y un difícil manejo durante el procedimiento quirúrgico, debido a la necesidad de mantener una presión venosa central elevada que garantice un adecuado flujo pulmonar, circunstancia que dificulta la consecución de una hipotensión controlada, habitual en estos procedimientos para el control del sangrado. Presentamos el caso de una paciente de 13 años con enfermedad congénita cardiaca (ECC) y fisiología de Fontán sometida a corrección quirúrgica de su escoliosis tóraco-lumbar, su manejo y mejora de la función cardiaca tras la cirugía raquídea mediante fusión raquídea posterior

Scoliosis can negatively impact the cardio respiratory function in patients with Fontan anatomy. Surgical treatment of the spinal curvature is advised when the consequences of the progression of the deformity on the survival and quality of life at the long term overcome the risks of the intervention. Unfortunately, this group of patients presents a high anesthetic risk and a difficult management during the surgical procedure, because they need to support a high central venous pressure to ensure an adequate pulmonary flow, circumstance which makes difficult to achieve a controlled hypotension, usual in these procedures for control of bleeding. We report here about a 13 years old patient with congenital heart disease (CHD) and Fontan physiology presented for posterior spinal fusion for the treatment of thoracolumbar scoliosis, her management and later progress of her cardiac function after the spinal fusion surgery

Do orthotic walkers affect knee and hip function during gait?

BACKGROUND AND AIM: Much previous research on orthotic walkers has focussed on their ability to offload structures in the foot and ankle; however, little is known about their effects on lower limb mechanics. This study aimed to determine effects of two orthotic walkers on the biomechanics of the knee and hip joints compared to standardised footwear. TECHNIQUE: A total of 10 healthy participants walked under three conditions: Walker A (Össur, Iceland), Walker B (DJO Global, USA) and standardised footwear (Hotter, UK). Kinematic and kinetic data were collected using a Qualisys motion analysis system (Qualisys Medical AB, Sweden) and force plates (AMTI, Boston, MA, USA). Significant differences were seen in hip kinematics and knee moments between walkers and standardised footwear and in knee kinematics between Walker A and standardised footwear. DISCUSSION: Both walkers show significant kinematic and kinetic differences compared with standardised footwear; however, Walker A appeared to produce greater deviation, including potentially damaging greater hyperextension moments at the knee. CLINICAL RELEVANCE: Further research is needed into the effects of orthotic walkers on knee and hip joint mechanics, which should help to inform future designs of walker, with greater focus on obtaining a more normal gait pattern.

Eficacia de las ortesis extensoras en el postoperatorio de la enfermedad de Dupuytren / Efficacy of extensor ortheses in the postoperative period in Dupuytren disease

Objetivo. Evaluar la eficacia de las ortesis extensoras en el postoperatorio de la enfermedad de Dupuytren. Estrategia de búsqueda. Revisión sistemática de la literatura en las principales bases de datos. Artículos en inglés publicados los últimos 10 años. Palabras clave usadas: Dupuytren y splint. Selección de artículos. Ensayos clínicos. Se obtuvieron un total de 3. Resultados y conclusiones. El uso de férulas extensoras asociado a la terapia manual no es más eficaz que el uso exclusivo de esta última en la recuperación de la extensión de los dedos afectados o en la recuperación de la función de la mano. Por ello, no se recomienda su uso (AU)

Objective. To evaluate the efficacy of extensor ortheses in the postoperative period in Dupuytren disease. Search strategy. A systematic review of the literature was conducted in the main databases. English articles published in the last 10 years were selected, using the keywords «Dupuytren» and «splint». Article selection. Clinical trials. Three articles were obtained. Results and conclusion. The use of extensor splints associated with hand therapy was not superior to the use of hand therapy alone in recovery of extension in the affected fingers or in the recovery of hand function. Therefore, the use of these splits is not recommended (AU)
