ABSTRACT
INTRODUCTION: Early intervention is essential for proper foot growth in postural congenital clubfoot (PCC), but little is known about its contribution to this deformity when subjects are evaluated through telemonitoring. OBJECTIVE: This study aimed to monitor the foot's flexibility of newborns diagnosed with PCC by telemonitoring them during the first months of life. METHODS: A longitudinal descriptive study was carried out with a full-term newborns group diagnosed with PCC in at least one limb, presenting a grade ≥ 0,5 on the Pirani score. Newborns with other malformations were excluded. They were assessed twice: before and 30 days after hospital discharge, and the foot flexibility classification by the Pirani score was provided. The telemonitoring occurred weekly between the assessments, and the parents were encouraged to mobilize their feet and maintain foot position using orthosis or taping. RESULTS: Thirteen newborns (eighteen feet) presenting PCC were included in this study; seven neonates discontinued the study due to absences from pre-scheduled evaluations, and six were telemonitored for 30 days. They were born at 39 weeks (± 1.18) and 3346.54 g (± 306.51). The majority of the newborns were female (69%), one was born vaginally, and eight (61%) had a family history of PCC. Pirani's score ranged from 1 to 3 in the initial assessment. After one month of telemonitoring, three feet progressed to 0, and four feet scored between 0.5 and 1. CONCLUSION: This study shows an important improvement in the foot's flexibility of newborns diagnosed with PCC evaluated through telemonitoring. Telemonitoring may be an additional resource for assisting newborns with PCC.
INTRODUÇÃO: A intervenção precoce é essencial para o correto crescimento do pé torto congênito postural (PTC), mas pouco se sabe sobre sua contribuição para essa deformidade quando os pacientes são avaliados por meio de telemonitoramento. OBJETIVO: Este estudo teve como objetivo acompanhar, por telemonitoramento, a flexibilidade do pé de recém-nascidos com diagnóstico de PTC durante os primeiros meses de vida. MÉTODOS: Foi realizado um estudo descritivo longitudinal com recém-nascidos a termo, diagnosticados com PTC em pelo menos um pé, apresentando escore de Pirani ≥ 0,5. Foram excluídos recém-nascidos com outras malformações. Os recém-nascidos foram avaliados nas primeiras horas de vida e 30 dias após a alta hospitalar. Durante este período os pais foram incentivados a mobilizar os pés diariamente e manter a posição por meio de órtese ou bandagem. O telemonitoramento ocorreu semanalmente, e a flexibilidade dos pés foi classificada pelo escore de Pirani. RESULTADOS: Foram incluídos neste estudo treze recém-nascidos (dezoito pés), sete descontinuaram o estudo por faltas nas tentativas de contato e seis foram telemonitorados por 30 dias. A maioria dos RN era do sexo feminino (69%), nasceram com 39 semanas (± 1,18) e 3.346,54g (± 306,51). Um nasceu de parto normal e oito (61%) tinham histórico familiar de PTC. Inicialmente, a pontuação de Pirani variou de 1 a 3. Após 30 dias de telemonitoramento, três pés evoluíram para 0 e quatro pontuaram entre 0,5 e 1. CONCLUSÃO: Este estudo mostra uma melhora importante na flexibilidade do pé de recém-nascidos com diagnóstico de PTC, avaliados por telemonitoramento. O telemonitoramento pode ser um recurso adicional para assistência ao recém-nascido com PTC.

Background and Objective The Projects of Global Growth of Medical Technologies, implemented by NCGM since 2015, have contributed to human resource development through on-site training in partner countries and training in Japan. However, since 2020, online training has become mainstream due to the travel restrictions by COVID-19 impact. As one of the projects, the NCGM and Bach Mai Hospital rehabilitation departments in Vietnam held an interactive online hands-on seminar in FY2022 for Vietnamese occupational therapists and others to provide technical guidance for making splint orthoses to rehabilitate patients with hand dysfunction. This paper aims to report on the preparation and implementation process of the seminar and its results.Preparation and Implementation of the Seminar NCGM (the instructor) and Bach Mai Hospital (the site of the hands-on training) prepared the seminar through regular online meetings, fostering ownership and collaborative planning on the Vietnamese side, and discussed the program development, necessary materials, participant selection, and obtaining authorization from the Vietnamese Ministry of Health. To ensure the quality of the technical instruction, the seminar was connected via Zoom to both NCGM and Bach Mai Hospital, where the live video of the splinting technique was conducted, along with explanations and Q&A sessions. The post-training evaluation was carried out through a questionnaire with self-assessment of the participants about the knowledge and skills they obtained. Outcome and Discussion As a result, 96% (27/28) of the participants answered that the seminar was “useful for clinical practice,” suggesting that the interactive online hands-on seminar regarding technical instruction in making splint orthosis was as good as or better than the face-to-face training. We found that the Vietnamese side took ownership from the preparatory stage by establishing a regular online meeting system; the quality of the training was assured by live video by both sides, which enabled detailed technical instruction; the training provider’s skills were improved by more detailed preparation; training was cost-effective compared to on-site training or training in Japan; and the materials used and the training videos can be used as teaching materials, which is expected local benefits and sustainability. These findings can be applied to face-to-face training to make the training more effective and extended as a useful method when similar activities are developed in other countries.
ABSTRACT
ObjectiveTo investigate the in-brace and short-term correction of 3D-printed scoliosis orthoses. MethodsFrom July to December 2021, 36 patients with adolescent idiopathic scoliosis from Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were selected to complete full-length radiographs of the spine before and immediately after wearing the orthosis. They wore the orthosis more than 20 hours a day, and took radiographs six months later. Cobb angle was calculated. They were assessed with Chinese version of the Scoliosis Research Society's outcomes instrument 22 (SRS-22) before wearing and six months follow-up. ResultsThe mean Cobb angle was (22.10±6.29)° before wearing, and it was (7.85±10.90)° immediately after wearing (t = 4.775, P < 0.01) and (14.33±0.74)° six months follow-up (t = 4.189, P < 0.01). The score of functional status of SRS-22 increased six months follow-up (Z = -2.676, P < 0.01). The Cobb angle immediately after wearing correlated with the Cobb angle six months follow-up (r = 0.826, P < 0.05). Conclusion3D-printed scoliosis orthoses can correct the scoliosis satisfactorily, in-brace and in short-term.
ABSTRACT
SUMMARY OBJECTIVE: Finger splints are used as a treatment option in tendon, bone, and soft tissue injuries. For immobilization, custom-made splints and prefabricated finger splints are used. In splints made for immobilization, it is aimed to limit joint movement. The aim of our study is to reveal how much custom-made splints and prefabricated finger splints limit joint motion (flexion angle in proximal interphalangeal and distal interphalangeal joints). METHODS: Custom-made splints and prefabricated finger splints were applied to the second fingers of the dominant side in a total of 40 individuals, 20 women and 20 men, not having any health problems. Individuals were asked to flex and joint motion was measured with the iPhone compass application. RESULTS: The mean distal interphalangeal joint angle values of the participants measured by prefabricated finger splints were found to be 24.27±8.29, and the mean distal interphalangeal joint angle values measured by custom-made splints was 0.52±1.50. There was a difference between the participants' distal interphalangeal joint angle values measured by prefabricated finger splints and custom-made splints (p<0.001). distal interphalangeal joint angle values measured with custom-made splints were significantly smaller than those measured with prefabricated finger splint. The mean of the participants' proximal interphalangeal joint angle values measured by prefabricated finger splints was 16.55±7.90, and the proximal interphalangeal joint angle values measured by custom-made splints was "0" for all participants. There was a difference between the participants' proximal interphalangeal joint angle values measured by prefabricated finger splints and custom-made splints (p<0.001). Distal interphalangeal joint angle values measured with custom-made splints were significantly smaller than those measured with prefabricated finger splints. CONCLUSION: According to our study, custom-made splints can significantly reduce the flexion of the finger interphalangeal joints compared to prefabricated finger splints.
ABSTRACT
Objective:To observe any effect of a half palm ankle-foot orthosis and a hollow-heel ankle-foot orthosis on the gait of stroke survivors.Methods:The walking of twenty-five stroke survivors was quantified using a gait analysis system. They walked barefoot, wearing a half palm ankle-foot orthosis and wearing a hollow-heel ankle-foot orthosis. Walking speed, step frequency, duration of the swing phase on the healthy and affected sides, risk of falling and Timed Up and Go (TUG) test times were recorded and analyzed.Results:The average gait frequency when wearing the hollow-heel ankle-foot orthosis was significantly faster than that in the other two conditions. The gait asymmetry coefficient was significantly different when the subjects wore the hollow-heel ankle-foot orthosis compared with walking barefoot. Compared with being barefoot, the average TUG time was significantly shorter when wearing either orthosis and the risk of falling was significantly less. The fall risk was significantly lower when wearing the hollow-heel orthosis compared to the half palm orthosis.Conclusion:Wearing either ankle-foot orthosis can significantly correct the gait of stroke survivors and lower their risk of falling, with better effect when wearing the hollow-heel ankle-foot orthosis.
ABSTRACT
Objective To evaluate the efficacy of additive manufacturing scoliosis orthosis, by simulation on interaction of the bone, trunk and orthosis using finite element method. Methods Combined with CT data of the patients, three-dimensional (3D) scanning model of the trunk and full length X-ray of the spine, the bone-trunk-orthosis finite element model was established and proved to be effective. The change and development trend of Cobb angle of the main thoracic scoliosis was calculated under different boundary and load conditions. Results The treatment effect of the additive manufacturing scoliosis orthosis was good. With the increase of orthotic preload, the improvement of Cobb angle and pelvic tilt was more obvious. The Cobb angle was expected to decrease by 6.18° after application of 70 N preload to the orthosis for 6 months. In the case of increasing system stiffness, Cobb angle improvement was not obvious and became even worse. Conclusions Additive manufacturing scoliosis orthosis is effective for treating adolescents with immature bones, while for patients with mature or degenerative bones, its treatment effect is poor.
ABSTRACT
A micro silicone oil liquid spring was designed and manufactured in this article. The performance of the liquid spring was studied by simulation analysis and mechanical test. A self-force source power-assisted knee orthosis was designed based on the liquid spring. This power-assisted knee orthosis can convert the kinetic energy of knee flexion into the elastic potential energy of liquid spring for storage, and release elastic potential energy to generate assisted torque which drives the knee joint for extension. The results showed that the average maximum reset force of the liquid spring was 1 240 N, and the average maximum assisted torque for the knee joint was 29.8 N·m. A musculoskeletal multibody dynamic model was used to analyze the biomechanical effect of the knee orthosis on the joint during knee bending (90°knee flexion). The results showed that the power-assisted knee orthosis could effectively reduce the biomechanical load of the knee joint for the user with a body weight of 80 kg. The maximum forces of the femoral-tibial joint force, patellar-femoral joint force, and quadriceps-ligament force were reduced by 24.5%, 23.8%, and 21.2%, respectively. The power-assisted knee orthosis designed in this article provides sufficient assisted torque for the knee joint. It lays a foundation for the subsequent commercial application due to its small size and lightweight.

Objective For patients with foot drop gait, to design a kind of anterior ankle foot orthosis (AFO) with adjustable stiffness, so as to restore natural gait of the ankle by limiting the patients’ unusual plantar flexion to the optimum extent. Methods The minimum orthodontic moment of 10 foot drop male patients was measured by self-made experimental equipment, which could be used to select optimum material modulus of the AFO. The relationship between elastic modulus and different filling structures and filling ratio parameters was studied by tensile test. A typical patient with foot drop was selected, and the anterior AFO fitting the shape of patient’s foot was quickly made by three-dimensional (3D) printing with foot geometric data and specific filling material, filling structure and filling rate. The kinematics and surface electromyography (sEMG) of plantar flexors were tested under barefoot and wearing two kinds of AFOs, so as to verify the effect of the AFO on plantar flexion. The effectiveness of the limitation and the degree of preservation of ankle valgus and plantar flexion were discussed. Results The minimum corrective torque required for 10 male patients with foot drop was 2.16 N·m. Compared with the rigid AFO, the range of motion (ROM) of plantar flexion and valgus increased by 67.8% and 88.6% respectively with the flexible AFO. The activation of the muscles responsible for plantar flexion (soleus, medial head of gastrocnemius and lateral head of gastrocnemius) also decreased by 38.3%, 46.6% and 55.8%. Conclusions This AFO with adjustable stiffness can be used for orthosis customization of patients with foot drop, providing more effective and long-term orthosis function and potential.
ABSTRACT
Objective:To compare the effects of compression garment combined with orthosis for central face on facial burn scar to compression garment and 3D compression mask. Methods:From September, 2016 to June, 2019, 38 facial burn scar patients received compression therapy in Department of Burns and Cutaneous Surgery, the First Affiliated Hospital of Air Force Medical University. According to their preference, they wore compression garment only (CG group, n = 15), compression garment and orthosis for central face (CO group, n = 17) and 3D compression mask (3D group, n = 6) for a year. The facial scar was assessed with Vancouver Scar Scale (VSS) before and after treatment, and the comfort and medical cost was investigated with questionnaire. Results:The VSS score decreased after treatment in all the groups (F = 18.49, P < 0.05), while the VSS score was higher in CG group than in CO group (1.717 points, 95%CI 0.925 to 2.482, P < 0.001) and 3D group (1.782 points, 95%CI 0.738 to 2.827, P < 0.001), the difference was less between CO group and 3D group (0.065 points, 95%CI -0.957 to 1.088, P = 1.000). The comfort rate was 60%, 52.9% and 66.7% for CG group, CO group and 3D group, respectively, with no significant difference (P > 0.05). The medical cost was the most for 3D group (12 000 to 16 000 Yuan), and similar for CG group (3000 to 4800 Yuan) and CO group (3300 to 5300 Yuan). Conclusion:Compression garment combined with orthosis for central face is more effective on facial burn scar, similar to 3D compression mask, but cheaper than 3D mask, which can be a choice for facial scar patients in developing areas.

ABSTRACT
@#Introduction: Every month, Sports National Institute (ISN) in Malaysia received around 3 to 4 cases associated with anterior cruciate ligament (ACL) injury involving athletes in hockey, kick volleyball and netball. Knee orthosis is one of treatment method and has been shown to support lower limb joint mechanics, which may protect the ACL injury for becoming worst. In this paper, an investigation was conducted to evaluate the performance of existing knee orthosis for treating ACL injury. Methods: Ten participants which have been grouped into two; six ACL patients (Group 1) and four healthy subjects (Group 2), where they took part in two bracing conditions; 1) with hinge (Brace 1) and 2) sleeve with bilateral hinges (Brace 2). A non-braced condition was included as a baseline measure. Three-dimensional kinematics data were used to calculate knee joint motions. Results: From the findings of ACL subjects, the knee flexion in non-braced condition (49.9°) has high value than others two braces, in which Brace 1 (40.9°) is less value than Brace 2 (44.6°). This shows the Brace 2 have higher degree of freedom than Brace 1. Other than that, the comfortability assessment found that Brace 2 is the most favourable options by participants in terms of less slippage and comfortless condition. Conclusion: In conclusion, the Brace 2 give best performance during dynamic balance activity in individuals who benefit from high degree of freedom and less slippage issue.
ABSTRACT
Objective：The knee joint in patients using a knee-ankle-foot orthosis (KAFO) is locked, and the lack of knee flexion can cause some problems in the gait, such as circumduction and excessive pelvic obliquity. Hence, a KAFO with knee flexion control was developed. This study aimed to compare the gait in stroke patients using KAFOs with a locked knee joint and a controlled knee joint.Methods：A newly developed electro-attractive-material (EAM) was used for the knee joint in the KAFO. The knee joint is locked in the stance phase, and released immediately after the manual switch is pushed by a physical therapist.The gait of seven stroke patients in the recovery phase was measured for KAFO with a locked knee joint (locked knee) and a controlled knee joint (EAM knee) . For gait measurement, an inertial sensor, a foot switch, and an EMG sensor were used.Results：The velocity increased and the swing time decreased in the EAM-knee as compared to the locked knee. The abduction, external rotation, and extension of the hip joint decreased in the EAM knee. Increased activity of the rectus femoris muscle in the loading response, and decreased activity of the longissimus doris in the swing phase were observed in the EAM knee.Conclusions：It was suggested that EAM KAFO could improve the gait parameter and reduce the movement on the paretic side by compensatory motions in the swing phase, thereby reducing the muscle activity of the longissimus doris muscle.
ABSTRACT
BACKGROUND: At present, the traditional orthosis manufacturing technology needs a lot of time and materials. The larger expansion coefficient of gypsum and the springback of material cooling will reduce the accuracy of orthosis. Therefore, the application of computer-aided design technology and three-dimensional printing technology in the field of orthosis is booming. OBJECTIVE: Based on the concept of multidisciplinary collaboration, a new scoliosis orthopedic device was designed and manufactured by optical scanning, computer-aided design and 3D printing, and its correction effect was evaluated. METHODS: Seven adolescent idiopathic scoliosis patients, who were treated in the Three-Dimensional Printing Center of Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University between March and October 2019, were enrolled in this study. The patient’s trunk was scanned with three-dimensional scanner. Virtual orthopedic treatment was conducted in Rodin4D software. Data were imported into Magics to carry out the hollow out design of orthosis, which was made by three-dimensional printing technology. Seven patients were followed up for 6 months after wearing orthopedic devices for more than 20 hours every day. The scoliosis before and after intervention was analyzed to observe the clinical efficacy. RESULTS AND CONCLUSION: (1) The contactless iPad scanner was successfully used for mold taking. The orthopedic model was designed in the French Rodin4D software, and the orthopedic model was hollowed-out by the Magics software. A suitable three-dimensional printed personalized scoliosis orthopedic device was produced through three-dimensional printing. (2) All the seven patients were improved significantly. Cobb angle before treatment was (29.43±7.68)°, and the angle of trunk inclination was (11.57±2.76)°. At 6 months after treatment, Cobb angle was (8.71±5.96)° (corrected 72%), and the angle of trunk inclination was (3.57±2.57)° (corrected 70%). The Cobb angle and angle of trunk inclination were significantly different before and after treatment (P < 0.01). (3) The digital medicine and 3D printing technology are applied in the field of rehabilitation AIDS, based on the concept of multidisciplinary collaboration. The production of personalized scoliosis orthopedic program is feasible, and the orthopedic rehabilitation effect is remarkable.

Abstract: Introduction: The Drop foot is a condition that is usually handled with short orthosis, usually made of polypropylene. It has also been described as being treated with silicon orthosis, little studied but which seem to improve the kinematic pattern of gait and, given its comfort, be more accepted by patients. Our study describes the kinematic characteristics of gait and patient satisfaction when using a silicon foot ankle orthosis, and compares this pattern to the non-use of the orthosis, in patients with a drop foot. Material and methods: Pseudo-experimental descriptive study in patients with dropped feet from 2010 to 2012, in which the kinematic variables of the gait pattern were evaluated from gait laboratories and in addition to the satisfaction of subjects with silicon orthosis and non-use of them. Results: Five patients with a drop foot were the subject of the study. Gait analysis of patients using the orthosis found an improvement in ankle position at initial contact, average walking speed and step length, as well as increased cadence. However, in terms of comfort compared to the non-use of the orthosis, the result was meager. Conclusions: Silicon foot ankle orthosis improve the position of the ankle in the initial contact, as well as the temporo-spatial parameters of the gait.

ABSTRACT Introduction: Diabetes mellitus is a chronic disease that is characterized by causing damage to the peripheral nervous system, generating sensory and motor changes. Objective: This study aims at analyzing the impact of the use of different orthotic insoles on the gait of diabetic female rats. Methods: Twenty-six female Wistar rats were randomly divided into the Control and Diabetic groups. The mechanical sensitivity test was performed manually on the surface of the animals' hind paws using the von Frey test. The functional evaluation was carried out on an adapted platform where the animals were stimulated to walk in order to capture images of the ventral region for measurements of the right and left hind paws. After the images were collected they were processed using Kinovea software version 0.8.27 to assess: stride distance, time, speed and acceleration. Results: There was a reduction in the weight of the animals in the Diabetic Group (p = 0.0018), associated with hyperglycemia (p = <0.0001), and a decrease in mechanical sensitivity as compared to the Control Group (p = 0.0372). Gait analysis showed a reduction in stride speed (p = 0.0482) and acceleration (p = 0.0149), with the silicone orthosis in the Diabetic Group. Conclusions: The silicone orthosis demonstrated a reduction in stride speed and acceleration, without compromising the other variables in the diabetic rats. The other insoles showed no functional difference between groups. Even though the animals showed a change in sensitivity at the end of 28 days of DM induction, this time does not appear to have been able to develop extensive changes in the rats' gait function.

RESUMO Introdução: O diabetes mellitus é uma doença crônica que se caracteriza por causar danos no sistema nervoso periférico, gerando alterações sensitivas e motoras. Objetivos: O presente trabalho tem como objetivo analisar o impacto do uso de diferentes órteses do tipo palmilha sobre a marcha de ratas diabéticas. Métodos: Vinte e seis ratas Wistar foram divididas randomicamente nos grupos Controle e Diabético. O teste de sensibilidade mecânica foi realizado manualmente na superfície da pata traseira dos animais com o teste de von Frey. A avaliação funcional foi feita em plataforma adaptada, na qual as ratas foram estimuladas a deambular, a fim de captar imagens da região ventral para medições das patas traseiras direita e esquerda. Depois da coleta, as imagens foram processadas no software Kinovea versão 0.8.27 para avaliar distância, tempo, velocidade e aceleração de um passo. Resultados: Observou-se redução do peso dos animais no Grupo Diabético (p = 0,0018), associado à hiperglicemia (p = <0,0001) e diminuição da sensibilidade mecânica em comparação com o Grupo Controle (p = 0,0372). Na análise da marcha, verificou-se redução da velocidade (p = 0,0482) e aceleração de um passo (p = 0,0149) com a órtese de silicone no Grupo Diabético. Conclusões: A órtese de silicone demonstrou redução da velocidade e da aceleração do passo, sem comprometimento das demais variáveis nas ratas diabéticas. As demais palmilhas não demonstraram diferença funcional entre os grupos. Ainda que os animais tenham apresentado alteração de sensibilidade, ao final de 28 dias de indução do DM, esse tempo parece não ter sido capaz de desenvolver alterações amplas na função da marcha das ratas. Nível de evidência II; Estudos terapêuticos - Investigação dos resultados do tratamento.

Resumen Introducción: El labio y paladar hendido son malformaciones craneofaciales que se presentan en 1:1000 nacidos vivos en Colombia. Realizar un moldeado nasoalveolar previo a la cirugía favorece el reposicionamiento de los cartílagos nasales deformados y de los procesos alveolares. Objetivo: Dar a conocer a los profesionales la importancia de realizar moldeado nasoalveolar en un paciente con labio y paladar hendido antes de la intervención quirúrgica. Materiales y métodos: En la clínica odontológica de la Universidad del Sinú de Montería (Córdoba, Colombia), se atendió una paciente de 17 días de nacida que presentaba labio y paladar hendido completo unilateral izquierdo severo. Luego de diligenciar la historia clínica odontológica, se realizó placa de órtesis, que se cambió cada 15 días y se hizo el retoque del "tutor" cada 8 días. Resultados: La placa de órtesis permitió un moldeado naso alveolar, con el progreso en la alimentación y mejoras en el contorneado de los tejidos nasales, que mejoró la preparación para la operación de la hendidura a los 8 meses de edad. Conclusiones: La importancia del moldeado nasoalveolar en casos como el presentado, es propiciar mejores condiciones físicas, favoreciendo la ingesta de alimentos y beneficiando la apariencia física.
Abstract Introduction: Cleft lip and palate is a craniofacial birth defect that accounts for 1:1000 live birhts in Colombia. Performing nasoalveolar molding before surgery facilitates the reshaping of deformed nasal cartilage and alveolar processes. Objective: To make professionals aware of the importance of performing nasoalveolar molding in a patient with cleft lip and palate before surgical intervention. Materials and methods: A 17-day-old infant with a full left unilateral cleft lip and palate was treated at the dental clinic of the University of Sinú, Montería (Córdoba, Colombia). Once the dental clinical history was recorded, an orthosis plate was made. The plate was changed every 15 days and the molding appliance was repositioned every 8 days. Results: The orthosis plate promoted nasoalveolar molding, which facilitated feeding and improved the shape of nasal tissues. Consequently, this early intervention improved the preparation for the surgery of the cleft when the child reached 8 months of age. Conclusions: Nasoalveolar molding in patients with full cleft lip and palate is important to promote better physical conditions, which favor food intake and benefit their physical appearance.

RESUMO Para a manutenção do equilíbrio, o organismo utiliza os sistemas visuais, vestibulares e proprioceptivos, que enviam informações para o sistema nervoso central acerca das condições do corpo com o objetivo de estabilizá-lo. Este estudo avaliou o efeito das palmilhas proprioceptivas sobre o equilíbrio postural estático e as dores musculoesqueléticas após dois meses de uso, por meio de uma pesquisa analítica longitudinal com 15 militares saudáveis do sexo masculino com média de idade de 34±7,5 anos. Eles foram submetidos à avaliação do equilíbrio por meio da plataforma Medicapteurs® e pelo protocolo CNT. Não houve diferença estatística para os desvios do corpo e velocidade do centro de pressão. A pressão plantar teve mudança estatisticamente significante para o pé esquerdo e o pé direito correspondendo a p=0,0001 e p=0,0007, respectivamente. Houve redução das médias de dores nos joelhos, pés e calcanhares e diminuição significativa da dor lombar, com p=0,0180. O equilíbrio estático não foi alterado significativamente com o uso das palmilhas proprioceptivas pelos militares, contudo elas proporcionaram melhor redistribuição das pressões plantares e parecem atenuar as dores musculoesqueléticas das extremidades inferiores. Por isso as palmilhas podem ser consideradas para esse grupo uma terapêutica de prevenção contra lesões relacionadas à sua atividade laboral.
RESUMEN Para mantener el equilibrio el cuerpo utiliza los sistemas visuales, vestibulares y propioceptivos, que envían información al sistema nervioso central sobre las condiciones del cuerpo para estabilizarlo. Este estudio evaluó el efecto de las plantillas propioceptivas sobre el equilibrio postural estático y los dolores musculoesqueléticas después de dos meses de uso, a través de una investigación analítica longitudinal con 15 soldados sanos con una edad media de 34±7.5 años. Ellos fueron sometidos a evaluación de equilibrio a través de la plataforma Medicapteurs® y por el protocolo CNT. No hubo diferencia estadística para las desviaciones del cuerpo y para la velocidad del centro de presión. La presión plantar tuvo un cambio estadísticamente significativo para el pie izquierdo y el pie derecho correspondiente a p=0.0001 y p=0.0007, respectivamente. Hubo una reducción en las promedio de los dolores en las rodillas, pies y talones y una disminución significativa en el dolor lumbar, con p=0.0180. El equilibrio estático no se modificó significativamente con el uso de plantillas propioceptivas por los militares, sin embargo, proporcionaron una mejor redistribución de las presiones plantares y parecen ablandar los dolores musculoesqueléticas en las extremidades inferiores. Por lo tanto las plantillas pueden considerarse para ese grupo como una terapia de prevención contra lesiones relacionadas con su actividad laboral.
ABSTRACT To maintain the balance, the body uses visual, vestibular and proprioceptive systems, which send information to the central nervous system about the body's conditions in order to stabilize it. This study evaluated the effect of proprioceptive insoles on static postural balance and musculoskeletal pains after two months of use, through a longitudinal analytical study with 15 healthy male soldiers with a mean age of 34±7.5 years. They were subjected to balance evaluation through the Medicapteurs® platform and by CNT protocol. There was no statistical difference for the deviations of the body and speed of the center of pressure. Plantar pressure had a statistically significant change for the left and the right feet, corresponding to p=0.0001 and p=0.0007, respectively. There was a reduction in the mean values of the pains in the knees, feet and heels and a significant decrease in lumbar spine pain, with p=0.0180. The static balance was not significantly altered with the use of proprioceptive insoles by the militaries; however, these insoles provided a better redistribution of plantar pressures and seem to attenuate the musculoskeletal pains of the lower extremities. Therefore, insoles can be considered as a prevention therapy against injuries for this group related to their work activity.

Objective:To observe the efficacy of compound wrist-hand orthosis-assisted training on wrist-hand dysfunction in patients with convalescent stroke. Methods:From June, 2018 to December, 2019, 34 stroke patients in our hospital were randomly divided into control group (n = 17) and experimental group (n = 17). Both groups received basic treatment and routine occupational therapy, while the experimental group wore a compound wrist-hand orthosis during and after the daily occupational therapy. The occupational therapy was carried out 30 minutes a time, twice a day for 14 days, and the non-training time orthosis wearing was carried out cumulative five hours a day for 14 days. Before and after treatment, the Brunnstrom stage (upper limb and hand) and Fugl-Meyer Assessment (FMA) (wrist and hand) were used to assess the motor function of the upper limbs and hands, while the modified Ashworth Scale (MAS) and modified Barthel Index (MBI) were separately used to assess the wrist tension and activities of daily living. Results:Two cases dropped out in the control group. There was no significant difference in Brunnstrom stage, FMA score, MAS score, and MBI score between two groups before treatment (P > 0.05). After treatment, the scores of FMA and MBI significantly improved in both groups (|Z| > 3.420, P < 0.01), and the improvement was higher in the experimental group than in the control group (Z = -2.895, t = 4.331, P < 0.01); while, no significant difference was found in Brunnstrom stages and MAS score in both groups (P > 0.05). Conclusion:The compound wrist-hand orthosis-assisted therapy could improve the wrist-hand motor function and activities of daily living in patients with convalescent stroke.
