CLINICAL AND FUNCTIONAL EVALUATION OF WRISTS AND HANDS OF SPINAL CORD INJURED PATIENTS.

Introduction: The inability of the spinal cord to propagate sensory and motor stimuli as a result of the disruption of the nerve tracts is called spinal cord injury. Objective: This study analyzes clinically and radiologically the hands and wrists of spinal cord injured patients, evaluating their motor and sensitive functionality, in order to determine if these patients are more likely to develop degenerative alterations. Methods: 14 patients (8 paraplegics and 6 tetraplegics) were evaluated, undergoing anamnesis and clinical examination - a scale of muscular strength (MRC - Medical Research Council) and the amplitude measurement of the movement with a manual goniometer (ROM), were used for objective evaluation - and x-ray exams. The results were compared with pre-existing data from other studies. Results: When asked, only one of the 14 observed patients complained about constant wrist pain, described as level 3 (weak to moderate), based on the visual analog scale (VAS). The motor evaluation, MRC and ROM divided the group of patients into two subgroups: paraplegic and tetraplegic patients. The x-ray analysis showed, based on Kellgren and Lawrence classification, that all exam images fit grades 1 or 2 of osteoarthritis and osteoarthrosis. Conclusion: In conclusion, spinal cord injured patients showed none or minimal clinical and radiological signs of osteoarthritis on hands or wrists. Overall, the hands and wrists of spinal cord-injured patients behave similarly to noninjured patients. Level of Evidence III; Retrospective Comparative Study.

Introdução: A incapacidade da medula espinhal de propagar estímulos sensoriais e motores como resultado do rompimento das vias nervosas é chamada de lesão da medula espinhal. Objetivo: Este estudo analisa clínica e radiograficamente mão e punhos de pacientes lesados medulares, avaliando função motora e sensitiva, a fim de determinar se estes pacientes estariam mais propensos a alterações degenerativas. Métodos: 14 pacientes (8 paraplégicos e 6 tetraplégicos) foram avaliados, passando por anamnese e exame clínico - sendo escala de força muscular (MRC - Medical Research Council) e a medição da amplitude de movimento com um goniômetro manual (ROM) foram utilizados para análise objetiva - e radiografias. Os dados obtidos foram comparados com literatura preexistente. Resultados: Quando questionados, apenas um dos 14 pacientes observados referiu dor crônica nos punhos, descrita como nível 3 (fraca a moderada), baseada na escala visual analógica. A avaliação motora, MRC e ROM dividiram os pacientes em 2 subgrupos: pacientes paraplégicos e tetraplégicos. A análise radiográfica mostrou, baseada na classificação de Kellgren e Lawrence, que todas as imagens se encaixam nos graus 1 ou 2 de osteoartrite e osteoartrose. Conclusão: Conclui-se, então, que pacientes lesados medulares apresentam nenhuma ou mínimas alterações clínicas e radiológicas para osteoartrite ou osteoartrose de punhos ou mãos. Ou seja, no geral, mãos e punhos de pacientes lesados medulares comportam-se como os pacientes sem lesão medular. Nível de Evidência III; Estudo Retrospectivo Comparativo.

Pain and quality of life in athletes vs non-athletes with spinal cord injury: Observational study.

Spinal Cord Injuries (SCI) may cause non-motor symptoms, such as chronic pain, which impair quality of life (QoL)Objective: To investigate the relationship between adapted competitive sports, pain, and QoL in people with SCI in a limited resources setting population.Methods: This prospective cross-sectional observational study involved 16 athletes and 24 non-athletes with SCI and collected data on demographic and clinical variables including scores for pain and pain interference in daily life (Brief Pain Inventory, BPI), neuropathic pain severity (Neuropathic Pain Symptoms Inventory, NPSI) and Quality of life (Word Health Organization Quality of Life Assessment, WHOQOL-BREF). Non-parametric testing was used to compare the groups, and due to athletes being younger, multiple linear regression analyses were used to adjust for the effect of sports practice on the outcome variables when adjusting for age.Results: Athletes were younger (median age 36y) than non-athletes (median age 41.5y; Mann-Whitney U test P = 0.011), and QoL was superior in athletes for the Physical, Psychological, Social Relationships, Self-Evaluation domains, and Total Score when adjusted for age (P < 0.01). Despite having no significant differences in pain intensity scores (NPSI, P = 0.742 and BPI, P = 0.261) athletes had less pain interference on "Relationship with Others", "Enjoyment of Life", and Total score (P < 0.05). Participation in competitive adapted sports (P = 0.004) and Total Pain Interference (P = 0.043) were significantly associated with QoL scores in the multiple linear regression analyses.Conclusion: Athletes with SCI have better QoL and less pain interference in some aspects of life when compared to non-athletes.

Upper extremity effort during the sit-to-stand task in able-bodied and in individuals with spinal cord injury: A preliminary study.

OBJECTIVE: To investigate the association between the presence of spinal cord injury (SCI) on biomechanical variables by comparing individuals with SCI and able-bodied individuals during the sit-to-stand (STS) task assisted by a walker device. Specifically, we compared the upper-extremity joint angles and moments, trunk forward tilt angle, vertical forces of the instrumented walker, and ground reaction forces between groups. DESIGN: Case-control study. SETTING: Department of Orthopedics and Traumatology, UNICAMP-Brazil. PARTICIPANTS: Six individuals with SCI and fourteen able-bodied individuals. MAIN OUTCOME MEASURES: Kinematics and kinetics of the shoulder, elbow, and wrist joints; trunk forward tilt angle, vertical walker forces, and ground reaction forces (GRF) were analyzed during the STS task in two phases: before and after the seat-off event. RESULTS: A higher peak elbow flexion angle and higher vertical walker forces were observed before the seat-off, whereas the lower peak vertical GRF was found, after the seat-off, in the SCI group compared with the control group. CONCLUSIONS: SCI affects kinematics and kinetics variables during the STS task compared to able-bodied controls. Individuals with SCI adopted different standing-up strategies that affected the distribution of the forces in the upper and lower extremities of the human body.

HETEROTOPIC OSSIFICATION AFTER SPINAL CORD INJURY: PREVENTION AND TREATMENT - A SISTEMATIC REVIEW.

Trauma configures the main cause of spinal cord injuries. Patients with traumatic spinal cord injury often develop severe and debilitating outcomes that require multidisciplinary care to adapt patients to their new reality. Heterotopic ossification (HO) is one of the frequent comorbidities in these patients but it still lacks well-established treatments or a gold standard one. Thus, this systematic review aimed to search the current literature for HO treatment and prevention. This study was conducted following PRISMA recommendations (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) and searches were conducted in three databases (PubMed, Embase, and Web of Science). A total of 193 articles were found in an initial search. After screening following the established criteria, eight articles were included in this review; of these, two reported prevention and the others, treatments. Based on data analysis, the use of non-steroidal anti-inflammatory drugs in the acute post-traumatic period proved to be the best method of prevention. In cases of mature HO or accompanied by ankylosis, surgical resection proved to be the most effective treatment despite the high rate of postoperative infections. Level of Evidence III, Systematic Review.

A principal causa de lesão medular é o trauma. O paciente com trauma raquimedular frequentemente evolui com incapacidades graves e debilitantes, fazendo com que necessite de cuidado multiprofissional para se adaptar a uma nova realidade. A ossificação heterotópica (OH) é uma comorbidade comum nesses pacientes, mas que ainda não tem tratamentos bem estabelecidos ou considerados padrão-ouro. Esta revisão sistemática teve como objetivo buscar formas de tratamento e prevenção da OH na literatura atual. O estudo seguiu a recomendação Principais Itens para Relatar Revisões Sistemáticas e Meta-Análises (PRISMA) e realizou buscas em três bases de literatura (PubMed, Embase e Web of Science). Foram encontrados 193 artigos inicialmente, e, após triagem considerando os critérios estabelecidos, oito foram eleitos para o trabalho final. Dois trabalhos abordaram a prevenção; e os demais, tratamentos. Pela análise dos dados, o uso de anti-inflamatórios não esteroidais (AINEs) no período agudo pós-traumático se mostrou como o melhor método de prevenção. Já em relação ao tratamento, nos casos de OH maduras ou com anquilose, a ressecção cirúrgica revelou-se como o método mais efetivo, a despeito da grande taxa de infecção pós-operatória.

Design and fast-fabrication of a system for functional electrical stimulation in upper limb of people with tetraplegia.

STUDY DESIGN: Proof of concept. OBJECTIVES: Standard Functional Electrical Stimulation (FES) systems can enhance motor learning in people with tetraplegia and are widely delivered by self-adhesive electrodes. Their limitations are dexterity, specific knowledge to place the electrodes on muscles, need to fix electrodes when they lose the gel layer, and time. We designed a new FES system, using an existing protocol of drinking-like movements, to the upper limb of a person with tetraplegia C5 that fits in any anthropometry and can be easily produced. Furthermore, we tested the system to assess its effectiveness and users' perception during FES rehabilitation. SETTING: São Carlos, SP, Brazil. METHODS: A shell was designed with parametric design and fast-fabrication methods, and a stimulation unit and a smartphone application were developed. Questionnaires assessed the perceptions of a patient and a physiotherapist, about the usability of the new system in relation to standard FES. Kinematic data of drinking-like movements were collected from the patient wearing both systems and compared with data from an aged-matched control subject. RESULTS: The results are a personalized shell and an intuitive FES system, overcoming the limitations of standard FES. The new system suggested better wrist-flexion control shown by the mean angles (-18.93°), then the other system (-59.35°), and compared with the control (-10.97°). CONCLUSIONS: Fast-fabrication with parametric design offers a promising alternative for personalizing FES systems, with potential for home use. Further studies are required including randomized clinical trials.

Biomechanical Gait Analysis of an Adult with Severe Hemophilia: A Case Report.

Hemophilia is characterized by recurrent bleeding into the joints leading to irreversible chronic arthropathy with reduced joint range of motion (ROM), which may lead to changes in gait patterns. To analyze the gait pattern in a 35-year-old male with severe hemophilia A, three-dimensional biomechanical analysis was performed during overground walking. The control group data from a public gait dataset of 10 healthy male individuals were used for comparison. The clinical examination was assessed with the Functional Independence Score in Hemophilia (FISH), Haemophilia Activities List (HAL), and Hemophilia Joint Health Score (HJHS). The biomechanical analysis demonstrated a pattern for both left knee and ankle joints with greater similarity to the control group compared to the right knee and ankle joints. ROM based on the HJHS questionnaire also showed greater impairment of the right-side knee joint compared to the left-side knee joint. This unique pattern could be the result of a compensation mechanism due to limited movement during the walking task and the surgical treatment.

RELIABILITY OF WIRELESS INSOLE BAROPODOMETRY OF NORMAL INDIVIDUAL'S GAIT.

OBJECTIVE: The plantar pressure distribution can be assessed quantitatively by computerized baropodometry such as carpet or insole. An insole-type system with wireless transmission was developed and plantar pressure results were previously validated by force platform. However, the reproducibility of the system had not been determined. Our objective was to evaluate the reliability of the results in different gait cycles, clinical characteristics and in different plantar anatomical sites. METHODS: 41 healthy adults (age, 34 ± 13 years; body mass index, 25 ± 5 kg/m2; 26 [63%], male, 26 [63%] practicing physical activity) were evaluated. Baropodometer evaluations were performed in 3 walking cycles with 100 m each, and the reliability between the cycles was examined. Pressure points on the heel, first metatarsal, fifth metatarsal and total plantar pressure were analyzed and compared. RESULTS: Moderate agreement was identified between the second and third cycles (ICC, 0.66; 95% CI, 0.14-0.83). Physical activity practitioners showed higher total plantar pressure (70.8 vs 68.2 Kpa; p = 0.04) and higher pressure in the heel (70.7 vs 68.1 Kpa; p = 0.036) in relation to sedentary ones. CONCLUSION: The insole was able to assess plant pressure with moderate reliability from the adaptation period. Level of Evidence III, Case control study - Investigating a diagnostic test.

OBJETIVO: A distribuição da pressão plantar pode ser avaliada quantitativamente por baropodometria computadorizada tipo tapete ou palmilha. Um sistema tipo palmilha com transmissão sem fio foi desenvolvido, cujos resultados de pressão plantar foram previamente validados por plataforma de força. No entanto, a reprodutibilidade do sistema não havia sido determinada. Nosso objetivo foi avaliar a confiabilidade dos resultados em relação a diferentes ciclos de marcha, características clínicas e em diferentes sítios anatômicos plantares. MÉTODOS: Foram avaliados 41 adultos saudáveis (idade, 34 ± 13 anos; índice de massa corpórea, 25 ± 5 kg/m2; 26 [63%], sexo masculino, 26 [63%] praticantes de atividade física). Avaliações com o baropodômetro foram realizadas em 3 ciclos de marcha com distância de 100 m, e avaliada a concordância entre os ciclos. Pontos de pressão no calcanhar, primeiro metatarsal, quinto metatarsal e a pressão plantar total foram analisados e comparados. RESULTADOS: Houve moderada concordância entre o segundo e terceiro ciclos (CCI, 0,66; IC95%, 0,14-0,83). Praticantes de atividades físicas apresentaram pressão plantar total (70,8 vs 68,2 Kpa; p = 0,04) e no calcanhar (70,7 vs 68,1 Kpa; p = 0,036) aumentada em relação aos sedentários. CONCLUSÃO: A palmilha foi capaz de avaliar a pressão plantar com confiabilidade moderada a partir do período de adaptação.

A low-cost easily implementable physiotherapy intervention clinically improves gait implying better adaptation to lower limb prosthesis: a randomized clinical trial.

Lower limb amputation highly impacts the lives of individuals. The inability to walk due to difficulties in adapting to wearing prosthesis can potentially result in physical degeneration and comorbidity in this population. In this randomized clinical trial study, we investigated if a low-cost and easily implementable physiotherapy intervention was effective in improving gait performance and adaptation to lower limb prosthesis in individuals with an amputation. A total of 26 individuals participated in the study, 16 with lower limb amputation and 10 without amputation. Participants with amputation were further divided in intervention and control groups. The intervention group underwent a rehabilitation protocol aimed at strengthening muscles and improving prosthesis adaptation. Muscle strengthening targeted the hip segment, prioritizing the abdominal muscles, hip flexors, extensors, adductors and abductors, followed by cicatricial mobilization and weight-bearing on the stump for desensitization. Assessment and measures were performed across the kinetic and kinematic parameters of gait. In the comparison between pre-and post-intervention, a significant increase in gait speed (0.68-2.98, 95% CI, 1.83, effect size ES) and cadence (0.56-2.69, 95% CI, 1.63, ES) was found between groups and time points. Step (0.73-3.11, 95% CI, 1.92, ES) and stride length (0.62-2.84, 95% CI, 1.73) increased between pre- and post-intervention, while in the control group both variables remained smaller. The intervention group decreased stance phase as a percentage of gait cycle between pre- and post-intervention (- 1.33-0.62, 95% CI, - 36, ES), while it increased in the control group. Improvement in a combination of important gait parameters indicates that the intervention protocol promoted the adaptation to prosthesis and the functional independence of individuals with lower limb amputation. It is recommended that the participants continue receiving follow-up assessments and rehabilitation interventions.

Effectiveness of a home-based therapeutic exercise program on lower back pain and functionality in Sickle Cell Disease (SCD) patients.

OBJECTIVE: To investigate the effectiveness of a home-based therapeutic exercise program on lower back pain and functionality of SCD patients. SETTING: A Hematology and Transfusion Medicine Center, University of Campinas (HEMOCENTRO-UNICAMP). METHODS: This was a prospective study, with a three-month follow-up of SCD patients with lower back pain. The lumbar spine functionality was evaluated by questionnaires, trunk flexion and extension analyses by fiber-optic-electrogoniometry and measurements of muscle strength of trunk flexor and extensors. The Intervention Group (IG) comprised 18 volunteers, median age 44y (28-58) and the control group (CG) comprised 15 volunteers, median age 42y (19-58), who did not perform exercises. The protocol consisted of daily home-based exercises with two evaluations: at the beginning and end of a three-month program. In order to compare the groups at baseline, the Fisher´s exact test and Mann-Whitney test were used for categorical and numeric variables, respectively. The Wilcoxon test was used for related samples comparing numeric measures of each group over time with a 5% (p < 0.05) significance level. RESULTS: After the intervention, patients demonstrated a significant improvement, according to the Visual-Analog-Scale (VAS; p = 0.01), Rolland Morris Disability questionnaire (RMDQ; p < 0.01) and trunk flexion and extension muscle strength (p < 0.01). No significant differences were found for the Start-Back-Screening-Tool-Brazil (SBST) and in measures of trunk flexion and extension range-of-motion (RoM). CONCLUSION: Results suggest that daily home-based exercises for a three-month period ameliorate pain and improve disability related to lower back pain and muscle strength.

PEDIATRIC FLEXIBLE VALGUS FLATFOOT CORRECTION BY ARTHROEREISIS.

OBJECTIVE: This article aimed to evaluate the efficacy of arthroereisis using synthetic polyethylene implants to correct excessive valgus deformity in pediatric patients with flexible valgus flatfoot. METHODS: Retrospective study of 20 pediatric patients with flexible valgus flatfoot, totaling 23 feet, between five and 14 years old, operated between January 2009 and July 2016. Clinical evaluations were performed by the Valenti podoscopic classification and the American Orthopaedic Foot & Ankle Society criteria, based on radiographic images and podoscopic analysis. These patients underwent surgical treatment with the introduction of a synthetic implant in the sinus tarsi. Multiple linear regression analysis with Backward selection of variables, angles of pre and postoperative of radiographic images of the patients submitted to arthroereisis were performed. RESULTS: The arthroereisis with interposition of synthetic material was satisfactory, considering that 91% of the cases presented clinical and radiographic improvement, with correction of angles and improvement in deformity degrees. Two cases presented implant loosening. The variables of the Bordelon and Pitch angles significantly influenced (p < 0,05) the improvement of the correction of deformity degrees. CONCLUSION: The arthroereisis with the interposition of synthetic polyethylene material showed to be an effective technique for flexible flatfoot in symptomatic pediatric patients.

ORTHOPEDIC RELATED COMORBIDITIES IN SPINAL CORD-INJURED INDIVIDUALS.

OBJECTIVE: This study aims to review, identify and study the determinations of the main orthopedic aspects in SCI patients. METHODS: A total of 80 articles from PUBMED and three theses (MSc. /DSc.) were examined. RESULTS: The results refer to the most essential joints. There is a chronic overload on the shoulder girdle due to the use of the upper limb as a supporting joint. The elbow presents osteoarthritis, subclinical, acute and chronic pain, mainly in quadriplegic patients. In the hand and wrist joints there are cases of paralysis, osteoporosis and osteoarthritis. Hips are the main weight-bearing joints while sitting which leads to a substantial degenerative process of this joint. Lastly, on the knee, feet and ankles, spasticity, contractures, osteoporosis and deformities can arise. CONCLUSION: Along with the increase in cases and research that analyze the alterations that spinal cord-injured individuals suffer, it is necessary to recognize the orthopedic changes to understand their limits and identify the relevance of the rehabilitation program to improve the muscle performance. Level of Evidence II, Prognostic Studies - Investigating the Effect of a Patient Characteristic on the Outcome of Disease.

OBJETIVO: O objetivo do estudo foi identificar, através de uma revisão sistemática, os aspectos ortopédicos e suas determinações nos pacientes lesados medulares. MÉTODOS: Foram examinados 80 artigos na base Pubmed e três teses de mestrado e doutorado. RESULTADOS: Os resultados obtidos referem-se às principais articulações. No ombro há uma sobrecarga crônica na cintura escapular devido ao uso como articulação de suporte. O cotovelo apresenta alterações osteocartilaginosas e dores subaguda, aguda e crônica principalmente no paciente tetraplégico. Nas articulações da mão e punho, a lesão leva à perda da capacidade de compressão por paralisia, osteoporose e osteoartrite. O quadril constitui a principal articulação de sustentação de peso quando sentado, ocorrendo um processo degenerativo importante nesses pacientes. Nos joelhos, pés e tornozelos surgem espasticidade, contraturas e osteoporose levando a deformidades. CONCLUSÃO: Devido ao aumento de casos e de pesquisas que analisam as alterações que os lesados medulares sofrem, se faz necessário o conhecimento das alterações ortopédicas do lesado medular para compreendermos a sua limitação e identificar a relevância do programa de reabilitação para melhora da performance muscular.

Bioinformatics analysis of circulating miRNAs related to cancer following spinal cord injury.

Patients with spinal cord injury (SCI) have an increased risk of developing esophageal, bladder and hematologic malignancies compared with the normal population. In the present study, we aimed to identify, through in silico analysis, miRNAs and their target genes related to the three most frequent types of cancer in individuals with SCI. In a previous study, we reported a pattern of expression of miRNAs in 17 sedentary SCI males compared with 22 healthy able-bodied males by TaqMan OpenArray. This list of miRNAs deregulated in SCI patients was uploaded to miRWALK2.0 to predict the target genes and pathways of selected miRNAs. We used Cytoscape software to construct the network displaying the miRNAs and their gene targets. Among the down-regulated miRNAs in SCI, 21, 19 and 20 miRNAs were potentially associated with hematological, bladder and esophageal cancer, respectively, and three target genes (TP53, CCND1 and KRAS) were common to all three types of cancer. The three up-regulated miRNAs were potentially targeted by 18, 15 and 10 genes associated with all three types of cancer. Our current bioinformatics analysis suggests the potential influence of several miRNAs on the development of cancer in SCI. In general, these data may provide novel information regarding potential molecular mechanisms involved in the development of cancer among individuals with SCI. Further studies aiming at understanding how miRNAs contribute to the development of the major cancers that affect patients after SCI may help elucidate the role of these molecules in the pathophysiology of the disease.

Alternative scapular stabilization exercises to target strength, endurance and function of shoulders in tetraplegia: A prospective non-controlled intervention study.

OBJECTIVE: Scapular stabilization exercises (SSE) are well-established for the able-bodies. The aim of the current study is to access the potential benefits of SSE on isometric internal and external rotator strength, endurance and function of the shoulder in persons with tetraplegia, throughout a 12-week exercise program consisting of five resisted movements with elastic bands. DESIGN: Prospective non-controlled intervention study. SETTING/PARTICIPANTS/INTERVENTIONS: A convenience sample of 17 subjects (age, 40.0±10.0 years old) with SCI was recruited from the University Hospital at the State University of Campinas (UNICAMP) from March 2015 to February 2016. They performed 5-resisted-SSE for 12 weeks, using Thera-band® elastic bands. Four evaluations were required: Baseline1, Baseline2, 6W and 12W. OUTCOME MEASURES: The dependent variables were isometric internal and external rotation strength, flexion and abduction endurance and the Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: Isometric external rotation strength and flexion endurance increased after SSE and were classified as "clinically relevant" using minimal importance difference (MID). Abduction endurance increased but it was classified as "not clinically relevant". DASH score reported no significant differences but it was classified as "potentially clinically relevant". Correlations were observed among time since injury and endurance improvements. CONCLUSION: This study demonstrated that specific training of the scapula muscles shows a benefit for shoulder strength, endurance and function of the shoulder in subjects with tetraplegia and should be part of the rehabilitation program. Besides, the SSE can be performed by subjects with tetraplegia themselves on a regular basis.

Circulating microRNAs, Vascular Risk, and Physical Activity in Spinal Cord-Injured Subjects.

The aim of this study was to compare the expression of serum microRNAs (miRNAs) in individuals with spinal cord injury (SCI) (athletes [SCI-A] and sedentary [SCI-S]) and able-bodied (AB) individuals, and investigate the relationship of miRNAs with carotid intima-media thickness (cIMT) and serum oxidized LDL-cholesterol (oxLDL) among SCI subjects. Seventeen SCI-S, 23 SCI-A, and 22 AB males were evaluated by clinical and laboratory analysis, and had oxLDL and cIMT measured by enzyme-linked immunosorbent assay (ELISA) and ultrasonography, respectively. A total of 754 miRNAs were measured using a TaqMan OpenArray® Human MicroRNA system. SCI-S subjects had higher cIMT and oxLDL than SCI-A and AB. Compared with AB, only one miRNA was differently expressed in both SCI-A and SCI-S individuals, whereas 25 miRNAs were differently expressed in SCI-S, but not in SCI-A. Of these 25 miRNAs, 22 showed different expression between SCI-S and SCI-A. Several miRNAs correlated with oxLDL and cIMT among all SCI individuals. Notably, miR-125b-5p, miR-146a-5p, miR-328-3p, miR-191-5p, miR-103a-3p, and miR-30b-5p correlated with both oxLDL and cIMT, and showed distinct expression between the SCI-A and SCI-S groups. Gene set enrichment analysis demonstrated that miRNAs related to cIMT and oxLDL may be involved in molecular pathways regulating vascular function and remodeling. In conclusion, this exploratory analysis suggests that variations in circulating miRNA expression in individuals with SCI compared with AB subjects are markedly attenuated by regular physical activity. Several miRNAs may be involved in physical activity-related improvements in vascular risk and remodeling among SCI individuals.

Evaluation of intra- and interobserver reliability of the AO classification for wrist fractures.

OBJECTIVE: This study evaluated the intraobserver and interobserver reliability of the AO classification for standard radiographs of wrist fractures. METHODS: Thirty observers, divided into three groups (orthopedic surgery senior residents, orthopedic surgeons, and hand surgeons) classified 52 wrist fractures, using only simple radiographs. After a period of four weeks, the same observers evaluated the initial 52 radiographs, in a randomized order. The agreement among the observers, the groups, and intraobserver was obtained using the Kappa index. Kappa-values were interpreted as proposed by Landis and Koch. RESULTS: The global interobserver agreement level of the AO classification was considered fair (0.30). The three groups presented fair global interobserver agreement (residents, 0.27; orthopedic surgeons, 0.30; hand surgeons, 0.33). The global intraobserver agreement level was moderated. The hand surgeon group obtained the higher intraobserver agreement level, although only moderate (0.50). The residents group obtained fair levels (0.30), as did the orthopedics surgeon group (0.33). CONCLUSION: The data obtained suggests fair levels of interobserver agreement and moderate levels of intraobserver agreement for the AO classification for wrist fractures.

OBJETIVO: Este estudo avaliou a confiabilidade interobservador e intraobservador da classificação AO para radiografias simples em fraturas do terço distal do punho. MÉTODOS: Trinta observadores, divididos em três grupos (residentes de ortopedia e traumatologia, ortopedistas e cirurgiões de mão), classificaram 52 fraturas do terço distal do antebraço com radiografias simples. Após quatro semanas, os mesmos observadores avaliaram as mesmas 52 fraturas em ordem aleatória. O índice kappa foi usado para estabelecer o nível de concordância entre os observadores individualmente e entre os grupos de residentes, ortopedistas e cirurgiões da mão, bem como para avaliar a concordância intraobservador. O índice de kappa foi interpretado conforme proposto por Landis e Koch. RESULTADOS: A confiabilidade interobservador global da classificação AO foi considerada baixa (0,30). Os três grupos apresentaram índices globais de concordância considerados baixos (residentes, 0,27; ortopedistas, 0,30 e cirurgiões da mão, 0,33). A concordância intraobservador global obteve índice moderado (0,41), foi maior no grupo dos cirurgiões da mão, no qual foi considerada moderada (0,50). No grupo dos residentes e ortopedistas foi considerada baixa, com valores de 0,30 e 0,33, respectivamente. CONCLUSÃO: A partir desses dados, concluímos que a classificação AO para fraturas do punho apresenta baixa reprodutibilidade interobservador e moderada reprodutibilidade intraobservador.

Impact of Regular Physical Activity on Adipocytokines and Cardiovascular Characteristics in Spinal Cord-Injured Subjects.

OBJECTIVE: To investigate the relationship of carotid artery intima-media thickness (IMT) and cardiac structure and function with adipocytokines in sedentary (S-SCI) and physically active (PA-SCI) subjects with spinal cord injury (SCI). DESIGN: Cross-sectional observational study. SETTING: Academic medical center. PARTICIPANTS: Men with chronic (>1y) SCI (N=41; 16 S-SCI, 25 PA-SCI) were evaluated. S-SCI subjects did not perform labor that required physical effort, recreational physical activity, or sports, while PA-SCI subjects included competing athletes who were regularly performing adapted sports. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Clinical, laboratory, carotid ultrasonography, and echocardiography analysis. Plasma leptin, adiponectin, and plasminogen activating inhibitor-1 (PAI-1) levels were determined. RESULTS: PA-SCI subjects had similar levels of adipocytokines, but lower carotid IMT and carotid IMT/diameter, and better left ventricular diastolic function than S-SCI participants. Bivariate analysis showed that adiponectin was inversely correlated with triglycerides (r=-.85, P<.001), low-density lipoprotein cholesterol (r=-.57, P<.05), and carotid IMT/diameter (r=-.56, P<.05) in S-SCI but not in PA-SCI participants. Additionally, the leptin-adiponectin ratio showed a direct correlation with triglycerides (r=.84, P<.001) and low-density lipoprotein cholesterol (r=.53, P<.05) in S-SCI but not in PA-SCI individuals. By contrast, the studied adipocytokines did not correlate with cardiac structure and function in PA-SCI and S-SCI participants. CONCLUSIONS: Lower adiponectin levels and higher leptin-adiponectin ratio are related to adverse vascular and/or metabolic characteristics in individuals with SCI. This relationship, however, appears to be mitigated by regular physical activity.

POSTURAL CONTROL ASSESSMENT IN PHYSICALLY ACTIVE AND SEDENTARY INDIVIDUALS WITH PARAPLEGIA.

OBJECTIVE: The aim of this study was to evaluate functional independence and trunk control during maximum-range tasks in individuals with spinal cord injuries, who were divided into sedentary (SSI, n=10) and physically active (PASI, n=10) groups . METHODS: Anamnesis was conducted and level and type of injury were identified (according to the American Spinal Injury Association protocol, ASIA) and the Functional Independence Measure (FIM) questionnaire was applied. For the forward and lateral reach task, the subjects were instructed to reach as far as possible. Mean data were compared using the unpaired t test and Mann-Whitney test and differences were considered significant when p<0.05 . RESULTS: The PASI group performed better in self-care activities (PASI: 40.8±0.42 points, SSI: 38.0±3.58 points, p=0.01), sphincter control (PASI: 10.5±1.84 points, SSI: 8.2±3.04 points, p=0.02), transfers (PASI: 20.7±0.48 points, SSI: 16.9±4.27 points, p=0.04), and total FIM score (PASI: 104.0±2.30 points, SSI 105.1±8.56 points, p=0.01). On the maximum reach task, the PASI group had a greater average range in all directions evaluated (p<0.05) . CONCLUSION: The continuous practice of exercise increased motor function independence and trunk control in individuals with complete spinal cord injury.
