Radiographic joint space width in individuals with hand osteoarthritis: Are their “healthy” joints really healthy?

We aimed to investigate the systemic nature of hand osteoarthritis (OA). We hypothesized that people who suffer from hand OA will display narrower radiographic joint space width (JSW) - not only in joints with apparent radiographic OA but also in their unaffected "healthy" joints. We examined 3394 participants from the Osteoarthritis Initiative (OAI) with available dominant hand radiographs at baseline. Cases were defined as having interphalangeal OA (IPOA) based on a Kellgren and Lawrence (KL) score of ≥2 in two or more finger joints, whereas controls did not have IPOA. We used custom software to make JSW measurements of the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints in fingers 2-5 per hand. In joint-level analyses, we included only KL score = 0, allowing us to compare all joints without IPOA in cases and controls. We used generalized estimating equation (GEE) models to compare JSW between both groups, adjusted for age, gender, metacarpal length, and joint type. Finger joints without radiographic OA had significantly narrower JSW in the IPOA group compared to finger joints in the control group (p<0.001). The differences were significant across all joint types and for both total JSW measurements as well as for central and lateral sub-regions within each joint group (p<0.001). Unaffected finger joints in people with IPOA had narrower joint space than joints of healthy controls. This implies a systemic nature of hand OA, in which people may have a predisposition for general cartilage deterioration.

Ameliorating Osteoarthritis in Mice Using Silver Nanoparticles.

Knee osteoarthritis (KOA) is one of the most commonly encountered degenerative diseases of the joints in people over 45 years of age. Currently, there are not any effective therapeutics for KOA,and the only end-point strategy is total knee arthroplasty (TKA); therefore, KOA is associated with economic burdens and societal costs. The immune inflammatory response is involved in the occurrence and development of KOA. We previously established a mouse model of KOA using type II collagen. Hyperplasia of the synovial tissue was present in the model, alongside a large number of infiltrated inflammatory cells. Silver nanoparticles have substantial anti-inflammatory effects and have been widely used in tumor therapy and surgical drug delivery. Therefore, we evaluated the therapeutic effects of silver nanoparticles in a collagenase II-induced KOA model. The experimental results showed that silver nanoparticles significantly reduced synovial hyperplasia and the infiltration of neutrophils in the synovial tissue. Hence, this work demonstrates the identification of a novel strategy for OA and provides a theoretical basis for preventing the progress of KOA.

ULTRASOUND DIAGNOSIS OF SUBACROMIAL FIBROSIS IN PATIENTS WITH ROTATOR CUFF IMPINGEMENT SYNDROME

Rotator cuff impingement syndrome (SURM) of the shoulder is considered one of the most common causes of pain in the shoulder joint in people of working age, mostly males. Due to the absence of characteristic signs of this pathology of the shoulder joint at the initial stage of the disease, fibrotic changes in the subacromial space (FI SAP) are detected late. The aim of the study was to evaluate the effectiveness of ultrasound navigation in the diagnosis and verification of fibrous changes in the subacromial space in patients with rotator cuff entrapment syndrome. Materials and methods. An analysis was made of 86 patients with cuff impingement syndrome, in whom fibrotic changes in the subacromial space are was initially detected according to ultrasound data. In group N1 (n1 = 42), the study data were analyzed without a minimally invasive intra-articular treatment procedure at the stage of conservative treatment, and in group N2 (n2 = 44) – with ultrasonic navigation of the subacromial space during a minimally invasive intra-articular treatment procedure. The comparison group (N3; n3 = 25) represented individuals without shoulder joint pathology. All patients underwent an ultrasound examination of the shoulder joint (Philips Sparq ultrasound scanner, linear high-density multifrequency transducer 5–13 MHz). Verification of the results of ultrasound of the shoulder joint is confirmed by the data of other methods of radiation imaging. Results. Ultrasound examination of the shoulder joint using dynamic functional tests before the start of therapeutic manipulations in patients with fibrotic changes in the subacromial space (in groups N1 and N2) visualization of the thickening of the supraspinatus tendon in combination with a decrease in the thickness of the subacromial space correlated with limitation of movement of the upper limb in the shoulder joint (p &lt; 0,001). Comparative results in the study groups showed that the use of ultrasound diagnostics and navigation technologies during a minimally invasive intra-articular treatment procedure for fibrotic changes in the subacromial space provides an improvement in clinical manifestations. Conclusions. The possibility of ultrasonic visualization of the supacromial space in normal conditions without pathological changes in the shoulder joint and with fibrous changes in the subacromial space allows us to recommend the proposed method of ultrasound examination of the shoulder joint to be included in the treatment and diagnostic algorithm for the syndrome of incarceration of the rotator cuff of the shoulder. Ultrasound navigation as an effective method for diagnosing and verifying subacromial fibrosis in patients with rotator cuff entrapment syndrome.

Papuan Rivalry and Harmony in Indonesia; Papua Student Racism Case in Surabaya City

Rivalry and harmony always go hand in hand, moreover as a marker for a group of children of the nation that we can call the existence of Papua who are sometimes treated discriminatory in their own country. Rivalry and harmony in Papua in the context of the Unitary State of the Republic of Indonesia is a serious problem, then it has the potential to pose a threat to social disparity and even national disintegration. The emergence of humanitarian incidents was motivated by the existence of discriminatory issues both carried out by fellow children of the nation themselves, as well as the civil apparatus of the state which should legally protect all children of the nation without exception. This research discusses cases of racism against Papuan students who live temporarily to carry out studies in the city of Surabaya, East Java in 2019. Therefore, this study uses a case approach from a phenomenological perspective. Phenomenological study is a thinking methodology (tools), the construction of ideas in viewing, understanding a phenomenon in an event in various experiences of subjectivity that is experienced by the subject himself, giving meaning and meaning to an event in the dynamics of everyday life (everyday life). Conclusion of the discussion states that ideology often appears spontaneously because it has penetrated into the joints of people's lives.

Neuromuscular joint function in knee osteoarthritis: A systematic review and meta-analysis.

Neuromuscular alterations are common in people with knee osteoarthritis (KOA). A comprehensive understanding of these alterations is important to enable targeted rehabilitation strategies. This systematic review and meta-analysis aimed to comprehensively understand the neuromuscular alterations around the knee joint in people with KOA. Moderate- and high-quality studies based on a modified version of the Downs and Black checklist, comparing neuromuscular function of peri‑articular muscles between people with KOA and controls were retrieved from five databases from inception to October 2020. Outcomes included normalized isokinetic strength, muscle size, voluntary activation, cortical and spinal-reflex excitability, and torque-related outcomes. Data were pooled according to structural KOA severity with sensitivity analysis based on sex. Evidence levels are presented in evidence gap maps. A total of 7 high-quality and 22 moderate-quality studies were retained (1146 people with KOA and 1353 age- and sex-matched controls). Studies demonstrated quadriceps and hamstring strength deficits and increased hamstring-to-quadriceps strength ratios across KOA severities. Women presented lower quadriceps strength at early KOA (very limited evidence) and lower voluntary activation at end stage KOA (very limited evidence) as compared with controls, whereas men did not (moderate evidence). People with KOA also demonstrated lower quadriceps force control ability with no change in rapid force production (very limited evidence). Voluntary activation deficits for quadriceps were evident (moderate evidence), with no change in quadriceps cortical excitability (very limited evidence) or soleus spinal reflexes (very limited evidence). No muscle size change was demonstrated except for the vastus medialis (limited evidence). Evidence gaps were found for neural and torque-related measures and differences in hamstring, gastrocnemius, soleus, and popliteus. Neuromuscular deficits are evident across different structural KOA severities and are seen in muscle strength, voluntary activation, muscle size, and force control ability. Women may exhibit these alterations to a greater extent than men. CRD42019160845.

Clinical and radiological assessment of joints in people with haemophilia in Assam, Northeast India: a cross-sectional study

Abstract Background Despite the availability of factor replacement therapy, including prophylaxis, to treat and prevent bleeding, haemophilic arthropathy continues to be the most common complication of haemophilia and significantly impairs the quality of life in people with haemophilia (PwH). Regular periodic assessment of joint status in PwH is essential to identify early arthropathic changes and prevent the development or progression of haemophilic arthropathy. Kinematic and kinetic assessment are preferable and MRI is the gold standard for diagnosing haemophilic arthropathy, but availability is limited in developing countries. HJHS and ultrasound in conjunction with HEAD-US have been shown to effective in assessing changes indicating arthropathy. Aim This study is designed to identify which radiological assessment tool(s) works best when integrated with clinical assessment tools to examine joint health in PwH, with the aim of establishing a cheap, effective, multimodal approach to joint assessment in clinical practice in low resource settings which can then help to guide treatment. Methods A cross-sectional observational study was carried out among PwH attending a clinic in the department of medicine at Assam Medical College and Hospital, Northeast India, over a one-year time period. The elbow, knee and ankle joints of participants were assessed clinically and functionally using HJHS and FISH and radiologically by Pettersson (X-ray) and HEAD-US (ultrasound) scoring. The resulting data was analysed statistically to ascertain correlation between these parameters. Results Sixty-seven PwH were enrolled in the study, with a mean age of 21.69±8.24 years (median 21 years); 38 (57.72%) had severe factor deficiency. The majority (71.70%) presented with joint bleeds; 40 (59.70%) had the knee as a target joint, followed by the elbow (11; 16.41%) and ankle (6; 8.95%). Mean ABR (annual bleed rate), AJBR (annual joint bleed rate) and ATJBR (annual target joint bleed rate) values had a positive correlation with increased severity of factor deficiency (p &lt;0.001). FISH score increased with factor activity level; HJHS, HEAD-US and Pettersson scores decreased with factor activity level. Significant positive correlation was established between Pettersson score, age and ABR. The degree of association was greatest between HJHS and HEAD-US at 60.62%; between HJHS and Pettersson it was 57.74%. Statistically significant negative correlation was established between FISH and HEAD-US. Conclusion A combined multimodal approach using the HJHS, FISH and HEAD-US scoring systems can provide a cheap, quick, more reliable and accurate option for assessing haemophilic joints, with minimal inter and intra observer reliability. This can support the optimisation of management of joint damage in PwH in resource-constrained settings.

Доверие как социокультурное и экономическое явление

The important role of confidence in public life consists in possibility of the effectiveness increase of all social phenomena and processes. In addition, confidence acts as a leading element of the mechanism of society integration into a single system. The purpose of the study is to analyze the role of confidence in culture transmission, which is a social experience accumulated in the process of people's joint activities. Confidence is an integral part of society's life and manifests itself in all its spheres, including economy. The research uses theoretical and empirical methods, in particular: literature review, logical and systematic analysis, methods of collecting empirical data, description, prediction and processing of the research results. In the course of the research, it was found that social scientists are almost unanimous: only culture determines the differences between human societies. Altruism, cooperation, and mutual trust, as models of social behavior, are determined by upbringing and social moral values. Today, it is obvious that confidence largely determines the effectiveness of interaction between social groups and functioning of public institutions. From the economic point of view, confidence is associated with economic growth and development, with efficiency increase of economic system functioning. The need for control, due to the predominance of distrust in the society is equivalent to introduction of additional tax on all types of economic activity. In conclusion, increase in the level of distrust in the world is stated, which causes serious concerns, because confidence is the foundation of society. The confidence crisis is not just a social phenomenon, but an important factor that determines many economic processes. Therefore, if governments intend to accelerate economic growth, they need to pursue policies aimed at strengthening confidence in the society.

Post-stroke rehabilitation of the ankle joint with a low cost monoarticular ankle robotic exoskeleton: Preliminary results.

Introduction: Stroke generates a high rate of disability and, in particular, ankle spasticity is a sequelae that interferes with the execution of daily activities. Robotic devices have been proposed to offer rehabilitation treatments to recover control of ankle muscles and hence to improve gait function. Objective: The aim of this study is to investigate the effects of passive stretching, combined with active and resisted movement, accompanied by visual feedback, by means of playful interactive software using a low-cost monoarticular robot (MEXO) in patients with stroke sequelae and spastic ankle. Methods: An open, uncontrolled, non-randomised, quasi-experimental study of 6weeks duration has been completed. A protocol has been defined to determine the usability, safety and potential benefits of supplementary treatment with the MEXO interactive system in a group of patients. Nine volunteer patients with sequelae of stroke who met the inclusion criteria were included. They received conventional treatment and in addition also received treatment with the MEXO monoarticular robot three times a week during 6weeks. Each session consisted of 10min of passive stretching followed by 20min of active movement training with visual feedback (10min active without resistance, 10min with resistance) and a final phase with 10min of passive stretching. The following variables were measured pre- and post-treatment: joint range of motion and ankle muscle strength, monopodal balance, muscle tone, gait ability and satisfaction with the use of assistive technology. Results: Statistically significant improvements were obtained in joint range measured by goniometry and in balance measured by monopodal balance test. Also in walking capacity, through the measurement of travelled distance. Discussion and significance: Device usability and patient safety were tested. Patients improved joint range and monopodal balance. The MEXO exoskeleton might be a good alternative for the treatment of spastic ankle joint in people with a stroke sequela.

The influence of iliotibial tract thickness on clinical outcomes in women with patellofemoral pain

BackgroundThe assessment of iliotibial tract thickness by ultrasonography may help identify a key, previously unexplored factor that may contribute directly to the homeostasis imbalance of the femoropatellar joint in people with patellofemoral pain (PFP). ObjectivesTo compare the iliotibial tract thickness of people with PFP and asymptomatic people; and to correlate the iliotibial tract thickness with self-reported pain and function of people with PFP. MethodsEighty women, separated into two groups: PFP group (n = 40) and control group consisting of asymptomatic participants (CG; n = 40). The participants answered the Anterior Knee Pain Scale (AKPS) questionnaire, to identify the self-reported knee function; they evaluated the pain in millimeters by the Visual Analog Scale for pain (VAS). For the imaging evaluation, an ultrasound was used, with a linear transducer at the distal portion of the iliotibial tract (coronal plane), with the participants positioned in dorsal decubitus, with 20° of knee flexion. The iliotibial band was visualized in its long axis, and three sequential images were recorded between the lateral femoral condyle and the lateral tibial condyle. The measurements were normalized and correlated. ResultsThe groups had no differences (P > 0.001) between participants for: age/weight/height/IMC. Participants in the PFP group had moderate levels of pain (58 + 2.1 mm), considerable self-reported functional limitation (d = 3.05) and greater iliotibial tract thickness compared with the CG (d = 2.41). ConclusionThe iliotibial tract of women diagnosed with PFP have greater thickness compared with asymptomatic women. There was no association between iliotibial tract thickness and subjective measures of pain and function.

Kinesio-taping 적용이 근·골격계 기능회복에 미치는 효과 검증 : A qualitative systematic review of evidence

Purpose: This study aims to find the effectiveness of the intervention of kinesio-taping in recovery of musculoskeletal disorders. Also, the study suggests some methodological issues identified in this qualitative systematic review.BR Method: A qualitative systematic review design was applied. DBpia and KISS were searched through January 2022 (keywords: taping, sports taping, balance taping, and kinesio taping). The papers meeting the inclusion and exclusion criteria by five steps were critically appraised for general methodological quality.BR Results: Two (4%) out of 55 identified papers were accepted to find the effect of the intervention of kinesio-taping on recovery from musculoskeletal disorders: one paper for patients with stroke and the other one for elderly people with knee pain. Both studies consistently found reduced pain in the short term. Also, the level of severity for subluxation of the shoulder joint has decreased. Furthermore, the degree of knee flexion has increased. However, we did not find any negative effects of the intervention of kinesio-taping on recovery from musculoskeletal disorders.BR Conclusion: There is limited evidence to suggest that kinesio-taping has a positive role in reducing pain, improving subluxation of the shoulder, and flexion of the knee joint in people with musculoskeletal disorders. These findings are about short-term effect. However, we did not find a long-term effect. More studies are required with a highly recognized methodological design.

Juvenile diabetes and systemic sclerosis: just a coincidence?

BackgroundLimited joint mobility (LJM), previously known as cheiroarthropathy, refers to the presence of reduced extension at the finger joints in people with diabetes and may be associated with scleroderma-like syndromes such as diabetic sclerodactyly.While scleroderma-like syndromes and LJM have been observed in patients with long-term diabetes and associated complications, the coexistence of diabetes with Juvenile systemic sclerosis (jSSc) is rarely described.Case presentationWe describe the case of a 14-year-old boy with long-lasting type 1 diabetes (T1D) and suspected LJM associated with Raynaud phenomenon, sclerodactyly and tapering of the fingertips. A comprehensive work-up showed positive autoantibodies (ANA, anti-Ro-52, anti-Mi-2b), abnormal nailfold capillaroscopy with a scleroderma pattern, interstitial lung disease and cardiac involvement. The overall clinical picture was consistent with the diagnosis of jSSc.ConclusionsLJM can be the initial sign of underlying systemic sclerosis. Nailfold capillaroscopy may help differentiate jSSc from classical LJM in pediatric patients with T1D and finger contractures or skin induration of no clear origin.This case report provides a starting point for a novel hypothesis regarding the pathogenesis of jSSc. The association between T1D and jSSc may be more than a coincidence and could suggest a relationship between glucose metabolism, fibrosis and microangiopathy.

Spirituality in Cheating Behavior: Evidence from Accounting Department Online Learning

COVID19 has penetrated into the joints of people's lives in the world. It shifts how society lives as a whole and learning process is one of the aspects that practically changed. Conventional learning switches over to online learning and as the consequences academic fraud behavior soaring. This paper aims to provide empirical evidence regarding the effect of pressure, capability, opportunity, rationalization and moderation effect of spirituality to academic fraud during online learning. This research is held in University of Trunojoyo Madura specifically accounting department. The subject of this study is college student in accounting department. Data obtained from deployment of online questionnaire, is processed with statistical tool namely SPSS. From the result it can be concluded that pressure, capability andopportunity positively and significantly affect academic fraud during online learning but rationalization not. In contrast, spirituality as independent and moderating variable not significantly affect academic fraud during online learning. The findings support fraud diamond theory partly but not social cognitive theory. This study offers some valuable knowledge, first the factor in fraud diamond theory such as pressure, capability, opportunity indeed enforce student to cheating. Second, spirituality is not negating academic fraud, so it gives insight to lecturer to improve the system in assignment and exam because student always tend to cheat when there is opportunity

Indonesian Journalism in the Era of Information Disruption

The phenomenon of online journalism requires that some providers of news content in conventional media transform themselves into multiplatform. It aims to be able to survive in the competition of the media industry. Not surprisingly, most of the conventional news media that still survive today have sites on the internet. Some only follow content from the parent company, but some others only provide additional material. These related sites operate to the same standards of practice and professionalism as their parent company does. It could be said that journalism is entering a time called a period of disruption. A period of disruption is a time when change occurs so unexpectedly, is fundamental and touches almost all joints of people's lives. And the presence of online journalism has revolutionized news where speed is a major factor. News is no longer an 'already ongoing' event, but an 'ongoing' event that should be broadcast by the media. Some features in online journalism are actually cited as a variety of causes of the erosion of idealism and credibility in online journalism. The impact of internet technology caused the online news media to undergo a radical revolution that made it different from journalism in the mass media in general.

Kinematics of the Lumbar Spine and Hip Joints in People with Persistent Low Back Pain during Sit to Stand and Stand to Sit Activities.

Background: To our knowledge, no study has examined the kinematics of lumbopelvic-hip complex of individuals with chronic low back pain (CLBP) who had lumbar flexion+rotation (F+R) syndrome during sit to stand (SiToSt) and stand to sit (StToSi) activities. Thus, this study aimed to examine movement patterns of the lumbopelvic-hip complex in participants with CLBP classified into F+R syndrome subgroup. Methods: This was a cross sectional study. A 3-dimensional motion capture system was used to record movements of the lumbar spine and hips during SiToSt and StToSi. Participants were 20 patients with LBP classified in lumbar F+R subgroup, based on the movement impairment system model, and 20 asymptomatic individuals. The study was approved by Shahid Beheshti University of Medical Sciences (IR, SBMU.RETECH, and REC.1395.365). Results: Greater and significant lumbar flexion, with SiToSt, and lumbar extension, with StToSi, were observed in the patients. In addition, the patients exhibited a greater magnitude of lumbar rotation during SiToSt. No significant difference was observed between the 2 groups in hip motions. Conclusion: The patients with lumbar F+R syndrome tend to move their lumbopelvic region to a greater extent in sagittal and horizontal planes during SiToSt and StToSi compared with participants without low back pain.

Musculoskeletal ultrasound for ankylosing spondylitis: A systematic review and meta-analysis.

Objective:To clarify if musculoskeletal ultrasound (US) would give additional information for the clinical examination to diagnose and evaluate the activity of ankylosing spondylitis (AS).Methods:A literature search was performed in PubMed, Embase, Web of Science, the Cochrane Library, Sinomed, Chinese National Knowledge Infrastructure (CINK), and Wanfang databases from their inceptions to May 15, 2020. Studies that examined the musculoskeletal US, which detected sacroiliac joints in people with AS were included. The pooled analyses were performed using Meta Disc version 1.4 software.Results:A total of 9 studies encompassing 984 participants were included. Statistical analysis suggested an area under the curve (AUC) of 0.9259 (sensitivity 0.86, specificity 0.54) indicating that US had excellent diagnostic test accuracy for AS, an AUC of 0.6441 (sensitivity 0.87, specificity 0.51) indicating that the US did not have a good diagnostic test accuracy for AS activity. A subgroup analysis revealed that the AUC of power Doppler US (PDUS) and color Doppler US (CDUS) was 0.5000 and 0.9274, respectively, indicating that CDUS was superior to PDUS.Conclusion:US, especially CDUS, is a valid and reproducible technique for the diagnosis of AS. While the accuracy of AS activity evaluation of the US is not ideal. It may be considered for routine use as part of the standard diagnostic tools in AS.

Toward Generalization of Bipedal Gait Cycle During Stair Climbing Using Learning From Demonstration

Lower limb assistive exoskeletons for rehabilitation is a growing field of study. They allow people with spinal cord injuries and strokes to stand upright and walk. Exoskeleton controls research typically focuses on trajectory generation, motion control over the trajectories, and balance and stability. This work focuses on the generalization of people's joint trajectories climbing a single stair, for an exoskeleton to be developed for people of all leg lengths and be used on variable stair heights. The motion of subjects of different heights, ages, and genders climbing a single stair was collected using motion capture. By using Gaussian mixed regression and Gaussian mixed models, these trajectories were combined to build a model that generalizes individuals with different leg lengths, genders, ages and stair heights. The variability of the subject's leg length is accounted for by tracking a marker on the toe of the subject and using inverse kinematics to calculate the joint angles. The analysis in this paper shows that joint angles can be generalized to climb various stair heights. In addition, an open-source database of motion capture climbing data and an open-source framework for generating joint trajectories has been made available for public use.

Comparison of the Position Sense of the Knee Joint in PatientsWith Multiple Sclerosis and Healthy Controls

Introduction: Position sense, one of the most accurate senses in the body, makes everyone aware of the state of the body in space. This sense is an essential ability in maintaining physical health and avoiding injury. Deficits in position sense cause balance impairments in people with mild Multiple Sclerosis (MS). Position sense requires instant and coordinated communication between the central nervous system and peripheral nervous system, while in patients with MS, communication between the brain and other parts of the body is disrupted. This study aims to compare the position sense of knee joint in people with MS and healthy subjects.&#x0D; Materials and Methods: Ten healthy subjects with the Mean±SD age of 27.6±3.71 years and 10 persons with MS disease and the Mean±SD age of 31.40±3.50 years participated in this study. For evaluating their position sense of knee joint, they flexed their knees (from 90 to 45 degrees) four times, and then a software calculated their repositioning errors.&#x0D; Results: No significant changes in repositioning errors (constant, variable, absolute) were observed in MS patients, and the control group (P˃0.05).&#x0D; Conclusion: The results indicate that mild MS disease cannot disturb the position sense of knee joint.

Effect of ankle sprain on postural control and electrical activity of selected muscles after single-leg jump landing task

Background: Ankle joint plays an important role in restoring the balance of individuals. Ankle sprain injury effects on balance of affected individuals. The changes in the postural control and activity of the ankle muscle, because of ankle sprain, can put the patients at reinjure risk and lower extremity injuries, especially during dynamic activities. The aim of this study was to investigate the electrical activity of ankle joint stabilizer muscles and postural stability after single-leg jump landing in individuals with ankle sprain. M aterials and Methods: In this cross-sectional study, 30 non-athletic students were participated. They were divided in two groups of 15 people, in the form of accessible and purposeful. Subjects was asked to land on a force plate with Single-leg, by at least 80% of their maximum jump. The com-cop changes assessment was used as an indicator for postural control evaluation. After jump landing, muscles activity was recorded on the ankle joint by surface electromyography (EMG) device. MATLAB software was used to analyze data, and MANOVA test was performed to compare two groups. R es ults: The results showed a significant reduction in EMG of soleus, gastrocnemius, and peroneus longus muscles (p=0.03, p=0.01 and p=0.006 respectively). Tibialis anterior activity significantly increased (p=0.001) in patient group than to healthy group. Postural control was significantly lower in patient group than healthy group, in all directions (p=0.00 and p=0.00 respectively). C onclusion: Decreased postural control indicates changes in EMG of the stabilizer muscles of this joint in people with ankle sprain injury.

Developing a new scoring scheme for the Hemophilia Joint Health Score 2.1

BackgroundThe Hemophilia Joint Health Score (HJHS) is a validated outcome tool developed for the assessment of joint health in people with hemophilia. The ordinal joint score assesses 9 items in 6 index joints. It is recognized as an optimal measurement of arthropathy in children and young adults. The aim of this study was to develop an updated scoring system for the HJHS that may overcome the limitations of its current ordinal scoring structure. MethodsA survey was developed using 1000Minds decision‐making software. Respondents were provided with discrete choice tasks of ranking alternatives to determine the preference weight, or relative importance, placed on different criteria for each HJHS item. The survey was distributed to an anonymous sample of health care professionals with extensive experience in the physical examination of joints in people with hemophilia. ResultsA total of 64 musculoskeletal health care professionals participated; with a 64% survey completion rate. The HJHS item weights provide a sum to 1.0; the highest‐ranked item was extension loss (0.139) followed by swelling (0.121), whereas the lowest was duration of swelling (0.057) followed by muscle atrophy (0.08). Compared to the original, the relative efficiency of the new score was 5.4. ConclusionsObserved differences in preference weights for HJHS items highlight the potential under‐ or overestimation of true joint health using the current ordinal scoring system. An updated scoring system using weighted items may improve the precision of HJHS assessment, leading to improved clinical management of joint health, while providing a robust research tool.
