A fun??o prim?ria do tornozelo/p? ? absorver o choque e proporcionar impulso para o corpo durante atividades funcionais. Enquanto se caminha, corre ou sobe e desce escadas, o complexo do p? precisa ser suficientemente male?vel para absorver os impactos de milh?es de contatos durante a vida. Por?m, os p?s podem apresentar diferentes posturas, como a prona??o excessiva dos p?s que est? associada a les?es musculoesquel?ticas prevalentes. Nesse contexto, com objetivo de reduzir a prona??o excessiva dos p?s comumente encontrada em indiv?duos com p? plano, palmilhas com cunha medial t?m sido prescritas buscando restaurar o padr?o normal das atividades funcionais sem dor, permitindo que o p? acomode as varia??es da superf?cie e proporcionam uma estabilidade adequada para a propuls?o. Em geral, levando em considera??o ao m?todo construtivo da ?rtese, as palmilhas s?o divididas em pr?-fabricadas, customizadas e palmilhas sob medida. Importante ressaltar que se deve realizar uma avalia??o minuciosa, e, dessa forma, pode-se atestar a real necessidade de seu uso. Outro ponto importante ? com rela??o a avalia??o cin?tica e cinem?tica das articula??es durante o uso das palmilhas, com este tipo de avalia??o ? poss?vel uma melhor compreens?o do desenvolvimento e risco de les?es. Nesse sentido, para analisar os dados achados, o mapeamento param?trico estat?stico (MPE) mostra-se superior, consiste ? uma t?cnica estat?stica aplicada usada para detectar sinais cont?nuos em espa?o-temporais.

The foot and ankle structures are fundamental to providing the human body with a stable base of support necessary for postural control. The primary function of the ankle/foot is to absorb shock and provide momentum to the body during functional activities. While walking, running or climbing and descending stairs, the foot complex must be malleable enough to absorb the impacts of millions of contacts over a lifetime. However, the feet can have different postures, such as excessive foot pronation, which is associated with prevalent musculoskeletal injuries. In this context, in order to reduce the excessive pronation of the feet commonly found in individuals with flat feet, medial wedge insoles have been prescribed to restore the normal pattern of functional activities without pain, allowing the foot to accommodate surface variations and provide a adequate stability for propulsion. In general, taking into account the constructive method of the orthosis, the insoles are divided into pre-fabricated, customized and made-tomeasure insoles. It is important to emphasize that a thorough evaluation must be carried out, and thus, the real need for its use can be attested. Another important point is related to the kinetic and kinematic assessment of the joints during the use of insoles, with this type of assessment it is possible to better understand the development and risk of injuries. In this sense, to analyze the data found, statistical parametric mapping (MPE) is superior, it is an applied statistical technique used to detect continuous signals in space-time.

No entanto al?m da a??o muscular, outras propriedades da articula??o do quadril como sua rigidez articular passiva merecem aten??o, pelo fato de contribu?rem durante a realiza??o dessas tarefas. Uma rigidez passiva adequada pode resistir ao movimento articular reduzindo a necessidade de contra??o muscular, e consequentemente o gasto energ?tico para promo??o da estabilidade funcional. Al?m disso, uma rigidez passiva adequada pode limitar a ocorr?ncia de padr?es de movimento rota??o medial do membro inferior e prona??o excessiva da subtalar, al?m diversas les?es nos membros inferiores, como, dor patelofemoral, les?o de ligamento cruzado anterior e s?ndrome do estresse tibial medial. OBJETIVO - Verificar a viabilidade de um estudo sobre o efeito do fortalecimento dos rotadores laterais na rigidez passiva, cin?tica e cinem?tica do quadril. M?TODOS - Foram realizados os seguintes testes: Teste isom?trico de rotadores laterais do quadril; amplitude de movimento passiva de rota??o medial do quadril; Cin?tica e cinem?tica do quadril durante agachamento unipodal. Os participantes foram aleatoriamente distribu?dos entre dois grupos. Grupo 1 - interven??o, grupo 2 - controle. O programa de fortalecimento muscular foi realizado 3 vezes a semana durante 8 semanas com carga de 80% de 1RM. A aloca??o dos participantes para cada grupo aleatorizada utilizando envelope pardo. Tr?s artigos comp?em esse estudo 1) Protocolo de Viabilidade de Estudo Cl?nico Aleatorizado; 2) Viabilidade de Estudo Cl?nico Aleatorizado; 3) Protocolo de Estudo Cl?nico Aleatorizado. RESULTADOS ? Tr?s dos cinco crit?rios de viabilidade previamente estabelecidos foram alcan?ados, n?o houve diferen?a significativas entre os grupos quanto aos desfechos de interesse para o estudo final. CONCLUS?O - O Estudo Cl?nico Aleatorizado ? vi?vel na popula??o sedent?ria. Disserta??o (Mestrado) ?

INTRODUCTION - The strength of the hip external rotator muscles (LR) is often investigated because it interferes with functional tasks such as gait, running vertical jump. However, in addition to muscle action, other hip properties joint, such as its passive joint stiffness, deserve attention because they contribute during the performance of these tasks. Passive stiffness is determined by the rate of change in resistance torque during angular displacement of a joint in the absence of muscle contraction. Adequate passive stiffness can withstand joint movement reducing the need for muscle contraction, and consequently energy expenditure to promote functional stability. In addition, adequate passive stiffness may limit the occurrence of movement patterns of lower limb internal rotation and excessive subtalar pronation, as well as several lower limb injuries such as patellofemoral pain, anterior cruciate ligament injury, and medial tibial stress syndrome. OBJECTIVE - To enable a more robust study to verify the effect of external rotator strengthening on passive, kinetic and kinematic hip stiffness. METHODS - The following tests was performed: Hip external rotator Isometric torque test; hip IR range of motion, hip and knee kinetics and kinematics. The participants were randomly distributed between two groups. Group 1 ? intervention and group 2 - control. The muscle strengthening program was performed 3 times a week for 8 weeks, three sets of eight repetitions with an intensity of 80% of one-repetition maximum (1RM) with a 2-min rest allowed between sets. The allocation of participants to each randomized group using the brown envelope. Three articles make up this study 1) Randomized Clinical Trial Viability Protocol; 2) Protocol Feasibility of Randomized Clinical Trial; 3) Randomized Clinical Trial. RESULTS - Three of the five previously established viability criteria were met, there was no significant difference between the groups regarding the outcomes of interest for the final study. CONCLUSION - Randomized Clinical Trial is feasible in sedentary population.

(PEP) ? um desalinhamento din?mico associado altera??es funcionais nos membros inferiores (MI), podendo gerar les?es de uso excessivo como a Dor Patelofemoral (DPF). Seus sintomas, como dor retropatelar trazem limita??es na vida di?ria, sobretudo em atividades mais intensas como na corrida. A PEP ? realidade em parte consider?vel de indiv?duos acometidos pela DPF. A literatura e a pr?tica cl?nica reconhecem a efic?cia do uso de palmilhas ortop?dicas na redu??o do movimento PEP. Neste contexto, o objetivo deste estudo foi verificar a dose-resposta do uso de palmilhas com cunhas mediais na cinn?tica e na cinem?tica dos MI e da pelve durante a marcha e a corrida de adultos com PEP. O estudo foi dividido em tr?s cap?tulos: 1) revis?o de literatura; 2) artigo cient?fico; 3) considera??es finais. A revis?o de literatura inicialmente abordou a anatomia de MI, seguida da descri??o do ciclo da marcha e da corrida e subsequente abordagem das les?es decorrentes de movimentos fora do padr?o normal. Emfim, as fun??es e efeitos das palmilhas com cunha medial ao longo do membro inferior foram relatados. O artigo cient?fico avaliou a dose-resposta do uso de palmilhas com cunhas mediais sobre a cin?tica e a cinem?tica dos membros inferiores e da pelve durante a marcha e a corrida. Nas considera??es finais, afirmou que as palmilhas com cunha medias podem alterar os padr?es de movimento e a mec?nica dos MI, podendo diminuir o risco de les?es por uso excessivo, como a dor patelofemoral.

Excessive foot pronation (EPP) is a dynamic misalignment associated with functional changes in the lower limbs (LL), which can lead to overuse injuries such as Patellofemoral Pain (PFP). Its symptoms, such as retropatellar pain, bring limitations in daily life, especially in more intense activities such as running. EPP is a reality in a considerable part of individuals affected by PFP. Literature and clinical practice recognize the effectiveness of using orthopedic insoles in reducing EPP movement. In this context, the aim of this study was to verify the dose response of the use of insoles with medial wedges on the kinetics and kinematics of the LL and pelvis during walking and running in adults with EPP. The study was divided into three chapters: 1) literature review; 2) scientific article; 3) final remarks. The literature review initially addressed the anatomy of LL, followed by the description of the gait and running cycle and subsequent approach to injuries resulting from non-normal movements. Finally, the functions and effects of medial wedge insoles along the lower limb were reported. The scientific article evaluated the dose-response of the use of insoles with medial wedges on the kinetics and kinematics of the lower limbs and pelvis during gait and running. In the final considerations, it was stated that mid-wedge insoles can alter the movement patterns and mechanics of the LL, which may reduce the risk of overuse injuries, such as patellofemoral pain.

Devido aos acoplamentos articulares dos membros inferiores, a redu??o da evers?o do calc?neo impede que o joelho e o quadril rode medialmente de forma livre, reduzindo o torque externo eversor de calc?neo, aumentando o torque externo adutor de joelho e reduzindo o torque externo rotador medial de joelho e quadril. Entretanto, a maior parte dos estudos avaliam os efeitos imediatos das palmilhas sobre a biomec?nica da marcha, n?o dando respaldo cient?fico se esses efeitos seriam mantidos com o passar do tempo. Objetivo: Avaliar os efeitos imediatos e a longo prazo do uso de palmilhas com cunha medial na cinem?tica e cin?tica dos membros inferiores durante a marcha em indiv?duos com prona??o excessiva dos p?s. M?todos: Dezenove indiv?duos com idade m?dia de 27,3 anos, IMC de 21,6 kg/m? e pontua??o de 9,87 no Foot Posture Index (FPI) foram recrutados. Os sujeitos realizaram uma caminhada usando uma palmilha interven??o com suporte de arco longitudinal medial e cunha medial de 6? de inclina??o no retrop? e uma palmilha controle plana. Os dados cinem?ticos e cin?ticos foram obtidos utilizando um sistema de captura de movimento tridimensional com 9 c?meras (Oqus 3+, Qualisys Medical AB, Gothenburg, Su?cia) captando a uma frequ?ncia de 200 Hz, sincronizado com tr?s plataformas de for?a FP4060-08 (Bertec, Columbus, Ohio, EUA) captando a uma frequ?ncia de 1000 Hz. Essas coletas foram realizadas em tr?s momentos (T1: coleta imediata; T2: ap?s 6 semanas e T3: ap?s 12 semanas) durante o per?odo de tr?s meses de uso das palmilhas interven??o pelos volunt?rios. Resultados: Ao utilizar a palmilha interven??o em compara??o com a palmilha controle, os volunt?rios apresentaram uma redu??o no pico de evers?o do calc?neo (p < 0,001, p?2 = 0,72), redu??o do torque externo eversor de calc?neo (p < 0,001, p?2 = 0,73) e redu??o na amplitude de movimento no plano coronal (p < 0,001, p?2 = 0,60), tanto no momento imediato quanto a longo prazo. Na articula??o do joelho, ao utilizar a palmilha interven??o houve redu??o no pico de rota??o medial (p = 0,015, p?2 = 0,46) e no pico de torque externo de rota??o medial (p = 0,001, p?2 = 0,44) durante o primeiro momento (T1) e ap?s seis semanas (T2), deixando de ser significativo ap?s 12 semanas de uso (T3). Houve tamb?m um aumento do pico de torque externo adutor de joelho (p < 0,001, p?2 = 0,68), com efeitos imediatos e a longo prazo (T1-T3). No quadril, os volunt?rios demostraram uma redu??o no pico de rota??o medial (p = 0,002, p?2 = 0,41) e pico de torque externo rotador medial (p = 0,025, p?2 = 0,25) e um aumento do pico de abdu??o do quadril (p = 0,005, p?2 = 0,37) ao utilizar a palmilha interven??o, entretanto essas diferen?as ocorreram somente a longo prazo (T3). J? o pico de torque externo rotador lateral do quadril (p < 0,001, p?2 = 0,61) e o pico de torque externo abdutor do quadril (p = 0,001, p?2 = 0,48) aumentaram ao usar a palmilha interven??o, com efeitos imediatos e a longo prazo (T1-T3). Conclus?es: A interven??o por palmilhas com suporte do arco longitudinal medial e cunha medial em compara??o a uma palmilha controle modifica a cinem?tica e cin?tica dos membros inferiores durante a marcha em adultos com prona??o excessiva, reduzindo o pico de rota??o medial do quadril a longo prazo e aumentando o torque externo adutor de joelho e diminuindo o pico de evers?o do calc?neo, a curto e longo prazo.

Introduction: Medially wedged insoles with medial longitudinal arch support act as a mechanical barrier against calcaneal eversion, limiting excessive foot pronation. Due to lower limb joint couplings, reduced calcaneal eversion prevents the free internal rotation of knee and hip, reduces calcaneal external evertor torque, increases knee external adductor torque and reduces knee and hip external medial rotator torque. However, most studies evaluate the immediate effects of the insoles on gait biomechanics, allowing no scientific support if these effects would be sustained over time. Purpose: To evaluate the immediate and long-term effects of using medially wedged insoles on lower limb kinematics and kinetics during gait in subjects with excessive foot pronation. Methods: Nineteen subjects with a mean age of 27,3 years, Body Mass Index (BMI) of 21,6 kg/m? and a Foot Posture Index mean score of 9,87 were recruited. The subjects walked wearing a 6? medially wedged insole with medial longitudinal arch support (hereafter intervention insole) and a flat control insole. Kinematic and kinetic data were obtained using a 9- camera three-dimensional motion capture system (Oqus 3+, Qualisys Medical AB, Gothenburg, Sweden) capturing at 200 Hz, synchronized with three FP4060-08 force plates (Bertec, Columbus, Ohio, USA) sampled at 1000 Hz. Data collection were performed in three moments (T1: Immediate collection; T2: After a 6 weeks intervention and T3: after 12 weeks) during the three-month intervention period. Results: The volunteers showed a reduced calcaneal eversion peak (p < 0,001, p?2 = 0,72), reduced calcaneal eversion external torque (p < 0,001, p?2 = 0,73) and a reduced coronal plane range of motion (p < 0,001, p?2 = 0,60) at the immediate and long-term period of use the intervention insole. At knee joint, the intervention insole decreased the internal rotation peak (p = 0,015, p?2 = 0,46) and decreased the internal rotation external torque peak (p = 0,001, p?2 = 0,44) during the first moment (T1) and after six weeks (T2), becoming not significant after twelve weeks of intervention. There was also an increased knee adduction external torque peak (p < 0,001, p?2 = 0,68), with immediate and long-term effects (T1- T3). The hip data showed a reduced internal rotation peak (p = 0,002, p?2 = 0,41), a reduced internal rotation external torque peak (p = 0,025, p?2 = 0,25) and an increased hip abduction peak (p = 0,005, p?2 = 0,37) wearing the intervention insoles, however these differences occurred only at the long-term period (T3). The peak of lateral rotator external torque (p < 0,001, p?2 = 0,61) and peak of abductor external torque (p = 0,001, p?2 = 0,48) increased when using the intervention insole, with immediate effects and long term (T1- T3). Conclusions: Intervention insole compared with control one effectively modify lower limb kinematics and kinetics during gait in adults with excessive pronation, decreasing the hip internal rotation peak at long term period, increasing the knee adduction external torque and reducing the calcaneal eversion peak at the short and long term period.

Essa condi??o est? entre as les?es de membro inferior que mais acometem os corredores. Fatores biomec?nicos locais vem sendo associados com a presen?a ou desenvolvimento da tendinopatia do calc?neo em corredores. Tais como, a prona??o excessiva da articula??o subtalar, o d?ficit de dorsiflex?o do tornozelo e a fraqueza dos m?sculos flexores plantares. Entretanto, recentemente, altera??es neuromusculares dos m?sculos do quadril tamb?m v?m sendo relacionadas com a tendinopatia do calc?neo. A intera??o entre fatores locais e n?o locais pode alterar a sobrecarga imposta no tend?o do calc?neo e contribuir com o desenvolvimento ou continuidade da tendinopatia de calc?neo em corredores. Objetivo: Verificar a contribui??o de fatores da articula??o do quadril e do complexo tornozelo-p? na ocorr?ncia de tendinopatia do calc?neo em corredores recreacionais. M?todos: Um estudo transversal foi conduzido com 51 corredores recreacionais, sendo 25 com tendinopatia do calc?neo e 26 saud?veis. Os participantes que reportaram e experimentaram dor na regi?o do tend?o do calc?neo durante a palpa??o foram inclusos no grupo tendinopatia. Em ambos os grupos, os participantes tinham que correr um m?nimo de 15km por semana e n?o ter hist?rico de les?o (outras que tendinopatia do calc?neo para o grupo lesionado) nos ?ltimos seis meses. A avalia??o do alinhamento perna-antep?, da amplitude de movimento (ADM) de dorsiflex?o de tornozelo e da ADM passiva de rota??o medial (RM) do quadril, al?m da for?a isom?trica dos m?sculos flexores plantares (FP) do tornozelo e dos rotadores laterais (RL) do quadril foi mensurada. A an?lise estat?stica foi feita atrav?s da ?rvore de Regress?o e Classifica??o e o c?lculo da ?rea abaixo curva ROC (Receiver Operatring Characteristic) foi realizado para determinar a acur?cia do modelo. Al?m disso, a raz?o de preval?ncia foi calculada para cada nodo terminal do modelo. Resultados: A intera??o entre ADM de RM do quadril, o alinhamento perna-antep?, a for?a de RL do quadril e FP do tornozelo foi capaz de distinguir os indiv?duos com e sem TC. O modelo foi capaz classificar corretamente 92% dos participantes do grupo controle e 72% do grupo TC. A ?rea sobre a curva ROC foi de 0.88 e significativamente diferente da hip?tese nula. Conclus?o: A intera??o entre fatores do tornozelo e quadril foi capaz identificar a ocorr?ncia de TC em corredores recreacionais. Os fisioterapeutas devem considerar uma avalia??o espec?fica para cada corredor com TC j? que diferentes padr?es biomec?nicos podem ocorrer em pacientes com esta mesma condi??o.

Introduction: Achilles tendinopathy is characterized by impairment, swelling and pain in the Achilles tendon region. This condition is one of the most prevalent lower limb injury in running practitioners. Biomechanical factors have been associated with AT presence or development in runners. Ankle excessive pronation, restricted ankle dorsiflexion and decreased Plantar Flexors (PF) strength are local factors often related with AT. Recently, non-local factors such as neuromuscular alterations of gluteal muscles has been investigated and associated with this condition. We suggest that an interaction between local and proximal factors may interfere in the Achilles tendon load and, therefore, contribute with the development or continuity of this condition in runners. Objective : To verify the contribution of the hip and ankle joint factors in the occurrence of Achilles tendinopathy in runners. Methods: A cross-sectional study was conducted with 51 recreational runners, 25 with Achilles tendinopathy and 26 healthy. Subjects that reported and experimented pain on Achilles tendon palpation were included in the AT group. In both groups, participants had to run at least 15km per week and had to be injury free in the last six months (no other injury besides Achilles tendinopathy in the injured group) to participate. We assessed the shank-forefoot alignment (SFA), ankle dorsiflexion Range of Motion (DFROM), hip Internal Rotation (IR) ROM as well as isometric strength of ankle PF and Hip External Rotators. The Classification and Regression Tree was used in the statistical analyses and the area under de Receiver Operatoring Characteristic curve was performed to establish the model accuracy. Additionally, the Prevalence Ratio (PR) of each terminal node was calculated. Results: The interaction between HIP IR ROM, SFA, ankle PF and hip ER strength were able to distinguish those runners with and without AT. Also, the model was capable to correctly classify 92% the participants from control group and 72% runners with AT. The area under the ROC curve was 0.88 which was significantly different from the null hypotheses. Conclusion: The interaction between ankle and hip clinical measures was capable of predict AT occurrence in recreational runners. Physical Therapists should consider a specific assessment of each runner with AT given that different biomechanical profiles may be related to the same outcome (AT).

A abdu??o do joelho est? relacionada ao aumento da adu??o do quadril, da rota??o medial do f?mur e da prona??o do p?, tais altera??es cinem?ticas podem ser influenciadas por altera??es de alinhamento estrutural, amplitude de movimento e for?a muscular. Especificamente, o varismo excessivo do antep?, a diminui??o da for?a muscular de rotadores laterais de quadril e o aumento da amplitude de movimento passiva de rota??o medial do quadril podem contribuir para o aumento da prona??o do p? e da rota??o medial da t?bia e f?mur, o que consequentemente pode contribuir para a abdu??o do joelho em cadeia fechada. Portanto, entender como estes fatores em conjunto interagem e influenciam a abdu??o do joelho permite desenvolvimento de estrat?gias de preven??o e reabilita??o mais eficientes. O objetivo da presente disserta??o foi investigar a influ?ncia do alinhamento do p?, torque muscular de rotadores laterais do quadril e amplitude de movimento passiva em rota??o medial do quadril na cinem?tica do joelho no plano frontal durante o agachamento unipodal. Quarenta e um indiv?duos participaram do estudo, sendo avaliados nos testes de torque isom?trico de rotadores laterais do quadril (TRLQ), amplitude de movimento (ADM) passiva de rota??o medial (RM) do quadril, alinhamento perna-antep? (APA) e avalia??o da cinem?tica do joelho no plano frontal durante o agachamento unipodal atrav?s do sistema de an?lise do movimento em 3D. A ?rvore de classifica??o e regress?o (Classification and Regression Tree - CART) foi utilizada para identificar os fatores e intera??es que est?o associados ao movimento do joelho no plano frontal. A curva receiver operating characteristic (ROC) foi usada para determinar a acur?cia do modelo desenvolvido pela CART. Finalmente, utilizou-se a raz?o de preval?ncia (RP) para identificar a for?a de associa??o das intera??es indicadas em cada nodo terminal da ?rvore com o desfecho. Os resultados revelaram que 14 indiv?duos (93,3%) classificados com abdu??o do joelho apresentaram menores valores de TRLQ (entre 0,26 e 0,47) e maiores valores de APA (>10,11?), com RP igual a 3,03. O modelo desenvolvido pela CART obteve acur?cia adequada (91,5% (IC 95%= 82,7-100) p < 0.0001), indicando como predi??o correta 81,8% de indiv?duos com abdu??o de joelho e 94,7% de indiv?duos com adu??o do joelho. Concluise que a abdu??o do joelho ? influenciada e depende da intera??o entre TRLQ e APA, sendo assim, indiv?duos com menores valores de TRLQ e maiores APA apresentam abdu??o do joelho.

The knee abduction during dynamic activities in closed kinetic chain is considered the main mechanism involved in non-traumatic knee injuries. Knee abduction is related to the increase in hip adduction, femur medial rotation and foot pronation. These kinematic changes can be influenced by modifications on structural alignment, range of motion and muscular strength. Specifically, the excess of forefoot varus, reduction strength of in the lateral hip rotators and increased passive hip medial rotation can contribute to a higher degree of foot pronation and medial rotation of tibia and femur, which may contribute to the abduction of the closed-chain knee. Therefore the understanding of how these factors interact to influence the keen abduction permits the development of prevention strategies and a more efficient rehabilitation. The aim of the study was to investigate the influence of foot alignment, hip lateral rotator torque and passive hip medial rotator range of motion on frontal plane knee kinematic during single leg squat. Forty one subjects participated in this study. They were tested on the hip lateral rotator isometric torque test (HLIT), passive range of motion (ROM) of hip medial rotator (MR), shank-forefoot alignment (SFA) and were assessed on the frontal plane knee kinematics during single leg squat using a 3D movement analysis system. The Classification and Regression Tree ? CART was used to identify factors and interaction that are associated to the occurrence of knee abduction. The receiver operation characteristic curve (ROC) was used to calculate the accuracy of the model developed by the CART. Finally, prevalence ratio (PR) was used to identify the strength of the association of the interactions indicated at each terminal node with the outcome. The results revealed that 14 subjects (93.3%) classified with knee abduction present lower HLIT values (between 0.26 and 0.47) and higher SFA values (>10.11?, PR=3.03). The model developed by CART had an adequate accuracy (91.5% (IC 95%= 82.7-100) p < 0.0001), indicating a correct prediction of 81.8% of the subjects with knee abduction and 94.7% of the subjects with knee adduction. In conclusion the knee abduction is influenced and depends on the interaction between HLIT and SFA. Subjects with a lower HLIT and higher FSA present knee abduction.
