Evaluation of ankle joint protection effect of parachute ankle brace on paratrooper landing / 中华劳动卫生职业病杂志

Objective: To study the protective effect of parachute ankle brace on ankle joint during simulated parachuting landing. Methods: In August 2021, 30 male paratroopers were selected as the test subjects by simple random sampling method. They jumped from the 1.5 m and 2.0 m height platforms respectively with and without parachute ankle brace, and landed on the sandy ground in a semi-squat parachute landing position. The experiment was divided into 1.5 m experimental group and control group and 2.0 m experimental group and control group. Angle sensor and surface electromyograph were used to measure and analyze the coronal tilt range of the ankle joint and the percentage of maximal voluntary contraction (MVE%) of the muscles around the ankle joint, respectively, to evaluate the protective effect of the parachute ankle brace. Results: At the same height, the tilt range of coronal plane of ankle in experimental group was significantly reduced compared with control group, and the difference was statistically significant (P<0.05). Under the same protection state, the tilt range of the coronal plane of the ankle in the 1.5 m group was significantly reduced compared with that in the 2.0 m group, and the difference was statistically significant (P<0.05). The coronal plane inclination range of the ankle in 2 m experimental group was significantly lower than that in 1.5 m control group, and the difference was statistically significant (P<0.05). Compared with 1.5 m control group, MVE% of right tibialis anterior muscle and bilateral lateral gastrocnemius decreased in 1.5 m experimental group, while MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle and right lateral gastrocnemius decreased in 2.0 m experimental group, while the MVE% of bilateral peroneus longus increased, with statistical significance (P<0.05). The MVE% of bilateral tibialis anterior muscle, bilateral lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m experimental group decreased compared with 2.0 m experimental group, and the differences were statistically significant (P<0.05). Compared with 2.0 m control group, the MVE% of bilateral tibialis anterior muscle, right lateral gastrocnemius muscle and right peroneus longus muscle in 1.5 m control group decreased, and the differences were statistically significant (P<0.05) . Conclusion: Wearing parachute ankle brace can effectively limit the coronal plane inclination range of ankle joint, improve the stability of ankle joint and reduce the load on the muscles around ankle joint by landing. Reducing the height of the jumping platform can reduce the coronal plane incline range of the ankle and the muscle load around the ankle during landing.

Curso Temporal de los Efectos Agudos de una Sesión de Estiramiento Muscular en Sujetos Jóvenes y Sanos / Time Course of the Acute Effects of a Muscle Stretching Session in Young and Healthy Subjects

Introducción. La duración de los efectos agudos del estiramiento muscular y su relación con el volumen total de estiramiento es un tema controversial. Método. Se distribuyeron aleatoriamente 29 varones jóvenes y deportistas en tres grupos: Control, "protocolo corto" (5 estiramientos x 30' segundos) y "protocolo largo" (10 estiramientos x 30 segundos). Para medir el efecto se usó el Active Knee Extension Test en forma previa y posterior a los 0, 3, 7, 12, 18 y 25 minutos. Cada medición se grabó en video, y se identificó el rango máximo de estiramiento con el software Kinovea. Se realizó comparación pre y postintervención entre grupos e inter grupo. Se incorporó análisis post hoc en medidas repetidas. Resultados. No hubo diferencias en la medición preintervención entre los grupos (P=0,266). Ambos protocolos tuvieron cambios significativos (P<0,007) respecto del grupo control (P=0,65). Todas las mediciones postintervención comparadas con la preintervención presentan diferencias en el protocolo corto (P≤0,018) y largo (P≤0,009). Hubo diferencia entre el grupo control con el de protocolo corto (P≤0,014) y control con protocolo largo (P≤0,004) para todas las mediciones, y una diferencia entre ambos protocolos en el post inmediato (P=0,033) pero no para las mediciones posteriores (P≤0,139). Conclusión. Un protocolo de 150 segundos de estiramiento estático en isquiotibiales en varones asintomáticos jóvenes, presenta efectos por al menos 25 minutos. Al duplicar a 300 segundos sólo presenta diferencia en la medición inmediatamente posterior. Por lo tanto, ambos protocolos son igualmente efectivos, pero el protocolo corto es más eficiente.

Background. The duration of the acute effects of muscle stretching and its relationship with the total volume of stretching is a controversial issue. Methods. 29 young male athletes were randomly distributed into three groups: control, "short protocol" (5 stretches x 30'') and "long protocol" (10 stretches x 30''). To measure the effect, the Active Knee Extension Test was used before and after 0, 3', 7', 12', 18' and 25'. Each measurement was videotaped, and the maximum range of stretch was identified using the Kinovea software. A pre-post intervention comparison was made between groups and inter groups. Post hoc analysis was incorporated into repeated measures. Results. There were no differences in the pre-intervention measurement between the groups (P=0.266). Both protocols had significant changes (P<0.007) compared to the control group (P=0.65). All post-intervention measurements compared to pre-intervention present differences in the short (P≤0.018) and long (P≤0.009) protocol. There was a difference between the control group with the short protocol (P≤0.014) and the control group with the long protocol (P≤0.004) for all measurements, and a difference between both protocols in the immediate post (P=0.033) but not for the measurements. subsequent measurements (P≤0.139). Conclusion. A protocol of 150'' of static stretching in hamstrings in asymptomatic young men, presents effects for at least 25'. When doubling at 300'', it only presents a difference in the immediately subsequent measurement. Therefore, both protocols are equally effective, but the short protocol is more efficient.

Ratio between maximum jaw opening and lateral excursion in brazilians with and without temporomandibular disorder / Razão entre abertura máxima e excursão lateral mandibular em brasileiros com e sem disfunção temporomandibular

Background: Mandibular movements (MM) can offer important information regarding temporomandibular joint health. Objective: Evaluate MM and the ratio between maximum jaw opening and mandibular lateral excursion in Brazilians with and without temporomandibular disorder (TMD). Methods: A cross-sectional study was conducted with 801 individuals between five and 80 years. All individuals answered a screening questionnaire; and MM were measured using digital calipers. The Mann-Whitney test was used to compare the differences between the sexes and groups with and without TMD. The Kruskal-Wallis test was used to determine differences in MM among age groups. Results: MM were smaller in individuals with TMD than in those without TMD. The ratio between jaw opening and lateral excursion was 5.23 in women without TMD and 5.59 in women with TMD. In males, the ratio was 4.75 and 5.52 in individuals without and with TMD, respectively. Conclusion: MM are smaller in Brazilians with TMD, whereas the ratio between jaw opening and lateral excursion is larger.

Cervical spine range of motion, posture and electromyographic activity of masticatory muscles in temporomandibular disorders / Amplitude de movimento articular cervical, postura e atividade eletromiográfica da musculatura mastigatória na disfunção temporomandibular / Rango del movimiento articular de la columna cervical, postura y actividad electromiográfica de la musculatura masticatoria en la disfunción temporomandibular

Abstract Introduction: Temporomandibular joint disorders (TMD or TMJD) involve clinical problems and symptoms affecting the temporomandibular joint (TMJ) and associated structures. The temporomandibular joints are anatomically connected to the cervical region, where cervical spine movements occur simultaneously to masticatory muscle activation and jaw movements. Objective: Our study sought to assess the relationship between the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), surface electromyography (sEMG) of the masticatory muscles, posture and cervical flexibility in women with TMD. Method: Fifty women with an average age of 27.0 ± 6.37 years, diagnosed with TMD according to RDC/TMD, were assessed for craniocervical posture, cervical flexibility and sEMG of the masticatory muscles. Results: There were no differences in jaw function limitations, depression, pain level and its interference in work ability and daily activities, posture and sEMG between TMD diagnoses or between muscle classification (p > 0.05). Depression scores were higher among participants with biarticular dysfunction (p = 0.023). The group with bruxism exhibited a higher pain level at assessment (p = 0.001) and a greater reduction in work ability (p = 0.039). Subjects with muscular and mixed TMD showed less cervical rotation to the right when compared with those with articular TMD. Conclusion: There was no difference in posture or sEMG values for TMD diagnoses, joint and muscle dysfunctions and the presence of bruxism. Muscle dysfunction is associated with reduced cervical rotation to the right. Jaw function limitations did not interfere in posture or sEMG and depression was associated with pain.

Effect of electroacupuncture on rehabilitation of knee joint movement after anterior cruciate ligament reconstruction / 中国针灸

OBJECTIVE@#To observe the effect of electroacupuncture (EA) on the rehabilitation of knee joint function after anterior cruciate ligament (ACL) reconstruction.@*METHODS@#A total of 140 patients with ACL reconstruction were randomly divided into an observation group (58 cases recruited, 12 cases dropped out) and a control group (65 cases recruited, 5 cases dropped out). The patients in the control group were treated with routine rehabilitation treatment. The patients in the observation group, on the basis of the treatment in the control group, were treated with EA at Fengshi (GB 31), Futu (ST 32), Zusanli (ST 36), Shangjuxu (ST 37), Fenglong (ST 40), Xuanzhong (GB 39), Diji (SP 8) and Sanyinjiao (SP 6) on the affected side (2 Hz/100 Hz of dilatational wave, 2-5 mA). Each EA treatment lasted 20-30 min, twice a day for 7 days. The swelling degree (d), pain visual analogue scale (VAS), knee joint range of motion (ROM), scores of International Knee Documentation Committee (IKDC) subjective short form and scores of Lysholm were observed in the two groups 1 day, 1 month, 3 months, 6 months and 1 year after operation.@*RESULTS@#One month and 3 months after operation, the swelling degree (d) and VAS scores in the observation group were lower than those in the control group (0.05). One month, 3 months, 6 months and 1 year after operation, the ROM of the knee joint in the observation group was higher than that in the control group (<0.05), the IKDC score and Lysholm score were higher than those in the control group (<0.05). Within one year, there were no relaxations, fractures and other related complications in the two groups. The pivot shift test, anterior drawer test and the Lachman test were all negative.@*CONCLUSION@#EA combined with routine rehabilitation training could obviously reduce the pain of knee joint, improve the swelling degree, increase the ROM of knee joint, promote the functional recovery in patients with ACL reconstruction, which are superior to rehabilitation training alone.

Static or dynamic stretching program does not change the acute responses of neuromuscular and functional performance in healthy subjects: a single-blind randomized controlled trial / Programa de alongamento estático ou dinâmico não altera as respostas agudas do desempenho neuromuscular e funcional de sujeitos saudáveis: ensaio controlado randomizado e cego / Un programa de estiramientos estáticos o dinámicos no modifica las respuestas agudas del rendimiento neuromuscular y funcional en individuos sanos: ensayo ciego controlado de distribución aleatoria

Abstract The purpose of this study was to compare the effects of a single hamstring static or dynamic stretching session and a 10-session stretching program on the range of motion, neuromuscular performance and functional performance of healthy subjects. Forty-five, healthy, active men were divided into three groups: control; static stretching and dynamic stretching. There were no significant differences in ratings between the experimental and control groups for any of the variables (p > 0.05). It can be concluded that neither a single session of hamstring static or dynamic stretching nor a 10-session stretching program affected range of motion, neuromuscular or functional performance.

ABSTRACT Objectives: To measure the quality of life and clinical outcomes of patients treated with interosseous membrane (IOM) ligament reconstruction of the forearm, using the brachioradialis (BR), and describe a new surgical technique for the treatment of joint instability of the distal radioulnar joint (DRUJ). Methods: From January 2013 to September 2016, 24 patients with longitudinal injury of the distal radioulnar joint DRUJ were submitted to surgical treatment with a reconstruction procedure of the distal portion of the interosseous membrane or distal oblique band (DOB). The clinical-functional and radiographic parameters were analyzed and complications and time of return to work were described. Results: The follow-up time was 20 months (6-36). The ROM averaged 167.92° (93.29% of the normal side). VAS was 2/10 (1-6). DASH was 5.63/100 (1-18). The time to return to work was 7.37 months (3-12). As to complications, one patient had an unstable DRUJ, and was submitted to a new reconstruction by the Brian-Adams technique months. Currently, he has evolved with improved function, and has returned to his professional activities. Three other patients developed problems around the transverse K-wire and were treated with its removal, all of whom are doing well. Conclusion: The new approach presented in this study is safe and effective in the treatment of longitudinal instability of the DRUJ, since it has low rate of complications, as well as satisfactory radiographic, clinical, and functional results. It allows return to social and professional activities, and increases the quality of life of these patients.

Late evaluation of patients undergoing manipulation of the knee after total arthroplasty / Avaliação tardia dos pacientes submetidos à manipulação do joelho após artroplastia total

ABSTRACT Objective: We compared gains in range of motion in patients who underwent manipulation within 12 weeks of total knee arthroplasty (TKA) and after this period. We also evaluated maintenance of the arc obtained from knee manipulation in late follow-up, along with factors associated with poorer outcomes. Method: The study was divided into two groups according to the time after TKA; the surgeries took place between January 2008 and December 2014. Results: When comparing the range of motion between early and late manipulations, the group that underwent manipulation within 12 weeks of the TKA exhibited better outcomes, but these were not statistically significant. We observed that 14.3% of cases retained the same range attained at the time of manipulation. In late evaluation after manipulation, 47.7% of the sample had a range of less than 90 degrees. The significant risk factors for recurrence of knee stiffness in the long term are poor range of motion before TKA and before manipulation, female sex, and secondary arthritis. Conclusion: Women previously diagnosed with secondary osteoarthritis and poor range of motion before TKA or manipulation are at higher risk for late stiffness. Level of Evidence III, Retrospective Comparative Study.

RESUMO Objetivo: Comparar o ganho de arco de movimento entre os pacientes submetidos à manipulação antes de 12 semanas pós-artroplastia total do joelho (ATJ), e depois desse período. Além disso, avaliar tardiamente a manutenção do arco obtido com a manipulação do joelho e fatores relacionados com os piores resultados. Método: O estudo foi dividido em dois grupos, de acordo com o tempo pós-ATJ. Os procedimentos ocorreram entre janeiro de 2008 e dezembro de 2014. Resultados: Quando comparamos os arcos de movimento entre as manipulações precoces e tardias, o grupo submetido à manipulação em 12 semanas da ATJ apresentou melhores resultados, porém, sem significância estatística. Foi observado que 14,3% dos casos mantiveram a mesma amplitude alcançada no momento da manipulação. Na avaliação tardia, 47,7% da amostra obtiveram amplitude menor que 90 graus. Os fatores de risco significantes para recidiva tardia de rigidez são arco de movimento ruim antes da ATJ e antes da manipulação, sexo feminino e artrites secundárias. Conclusão: Mulheres com diagnóstico prévio de osteoartrite secundária e com arco ruim antes da ATJ ou da manipulação têm maior risco de rigidez tardia. Nível de Evidência III, Estudo Retrospectivo Comparativo.

Validation of Attitude and Heading Reference System and Microsoft Kinect for Continuous Measurement of Cervical Range of Motion Compared to the Optical Motion Capture System

OBJECTIVE: To compare optical motion capture system (MoCap), attitude and heading reference system (AHRS) sensor, and Microsoft Kinect for the continuous measurement of cervical range of motion (ROM). METHODS: Fifteen healthy adult subjects were asked to sit in front of the Kinect camera with optical markers and AHRS sensors attached to the body in a room equipped with optical motion capture camera. Subjects were instructed to independently perform axial rotation followed by flexion/extension and lateral bending. Each movement was repeated 5 times while being measured simultaneously with 3 devices. Using the MoCap system as the gold standard, the validity of AHRS and Kinect for measurement of cervical ROM was assessed by calculating correlation coefficient and Bland–Altman plot with 95% limits of agreement (LoA). RESULTS: MoCap and ARHS showed fair agreement (95% LoA10°) for measuring ROM in all directions. Intraclass correlation coefficient (ICC) values between MoCap and AHRS in –40° to 40° range were excellent for flexion/extension and lateral bending (ICC>0.9). ICC values were also fair for axial rotation (ICC>0.8). ICC values between MoCap and Kinect system in –40° to 40° range were fair for all motions. CONCLUSION: Our study showed feasibility of using AHRS to measure cervical ROM during continuous motion with an acceptable range of error. AHRS and Kinect system can also be used for continuous monitoring of flexion/extension and lateral bending in ordinary range.

The Effect of Distal Location of the Volar Short Arm Splint on the Metacarpophalangeal Joint Motion

BACKGROUND: The goals of this study were to compare maximal metacarpophalangeal joint (MCPJ) flexion angles after application of a volar short arm splint at 3 different locations and verify the relations between the three different physical and radiological locations. METHODS: Forty dominant hands of healthy subjects were analyzed in the study. We defined a transverse skin folding line as a line drawn from the radial aspect of the thenar crease to the ulnar aspect of the distal transverse palmar crease. The distal end of the volar short arm splint was applied on 3 parallel locations to this line. Location A was on this transverse skin folding line; location B was 1 cm proximal to location A; and location C was 1 cm distal to location A. Two orthopedic surgeons measured the maximal MCPJ flexion angles of each finger except the thumb with the application of a volar short arm splint at 3 different locations as well as without a splint as a control. Radiological locations of the 3 different distal ends of the volar short arm splint were also assessed by anteroposterior radiographs of the wrist. RESULTS: When the splint was applied at location A and C, the maximal MCPJ flexion angle decreased to a mean of 83° (91% of control value) and 56° (62% of control value), respectively (compared to the control, p < 0.001). At location B, the maximal MCPJ flexion angle was a mean of 90° (99% of control value); no significant difference was observed compared to the control or without the splint (p = 0.103). On radiography, the average length from the metacarpal head to the distal end of the splint at all fingers decreased in the order of location B, A, and C (29 mm, 19 mm, and 10 mm, respectively; p < 0.001). CONCLUSIONS: We recommend applying the distal end of a volar short arm splint at proximal 1 cm to the transverse skin folding line to preserve MCPJ motion perfectly, which is located at distal 44% of the whole metacarpal bone length radiologically.

Influência da manipulação osteopática na amplitude de rotação da coluna cervical em indivíduos com cervicalgia mecânica crônica / Influence of manipulation at range of rotation of the cervical spine in chronic mechanical neck pain

JUSTIFICATIVA E OBJETIVOS: A amplitude de movimento do pescoço pode ser reduzida pela presença de disfunções vertebrais e miofasciais, as quais podem ser tratadas pela manipulação osteopática por meio da técnica articulatória rítmica cervical. O objetivo deste estudo foi verificar se a manipulação osteopática, através da técnica articulatória rítmica gera aumento da amplitude de rotação cervical mensurada por fleximetria. MÉTODOS: A casuística foi constituída de 58 indivíduos de ambos os gêneros, com idade média de 36±6,5 anos, com cervicalgia mecânica crônica, que foram submetidos de maneira randomizada à fleximetria controle da rotação cervical, à manipulação osteopática, por meio da técnica articulatória rítmica, ao repouso de 5 minutos e à fleximetria estudo da rotação cervical. RESULTADOS: A comparação entre as médias das fleximetrias de rotação cervical através do teste t de Student para dados pareados, ao nível de significância de 0,05 (5%), mostrou que houve aumento significativo da rotação cervical em todos os casos (p<0,05) passando de 151,4º para 162,5º no arco total de movimento (aumento de 7,3%). CONCLUSÃO: Os resultados foram dentro do esperado, confirmando que a manipulação osteopática, através da técnica articulatória rítmica gerou aumento significativo da amplitude de rotação cervical em todos os casos, podendo servir de tratamento de doenças que se relacionam à redução da mobilidade vertebral, como cervicalgia e osteoartrite cervical.

BACKGROUND AND OBJECTIVES: Neck range of motion may be decreased by vertebral and myofascial dysfunctions, which may be treated with osteopathic manipulation through the cervical rhythmic articulatory technique. This study aimed at verifying whether osteopathic manipulation with rhythmic articulatory technique improves cervical rotation range measured by fleximetry. METHODS: The group was made up of 58 individuals of both genders, mean age of 36±6.5 years, with chronic mechanical neck pain, who were randomized to cervical rotation control fleximetry, to osteopathic manipulation through the rhythmic articulatory technique, to 5-minute rest and to cervical rotation study fleximetry. RESULTS: The comparison of cervical rotation fleximetry means through Student's t test for paired data at significance level of 0.05 (5%) has shown significant cervical rotation improvement in all cases (p<0.05), going from 151.4º to 162.5º in total movement arch (7.3% improvement). CONCLUSION: Results were as expected, confirming that osteopathic manipulation using the rhythmic articulatory technique generates significant improvement of cervical rotation range in all cases and may be an alternative to treat diseases related to vertebral mobility reduction, such as neck pain and cervical osteoarthritis.

Spinal Mobility, Vertebral Squaring, Pulmonary Function, Pain, Fatigue, and Quality of Life in Patients With Ankylosing Spondylitis

OBJECTIVE: To investigate the relationships between spinal mobility, pulmonary function, structural change of the spine, pain, fatigue, and quality of life (QOL) in patients with ankylosing spondylitis (AS). METHODS: Thirty-six patients with AS were recruited. Their spinal mobility was examined through seven physical tests: modified Schober test, lateral bending, chest expansion, occiput to wall, finger to ground, bimalleolar distance, and range of motion (ROM) of the spine. Pulmonary Function Test (PFT) was performed using a spirometer, and vertebral squaring was evaluated through the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). QOL, disease activity, functional capacity, and fatigue were evaluated by SF-36 Health Survey (SF-36), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), and the Multidimensional Assessment of Fatigue (MAF) scale, respectively. Perceived physical condition and degree of pain were assessed using 10 cm visual analogue scale. RESULTS: Participants showed reduced spinal mobility, which was negatively correlated with mSASSS. PFT results showed reduced forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) and increased FEV1/FVC. Reduced FEV1 and FVC showed positive correlations with reduced spinal mobility and a negative relationship with mSASSS. Perceived physical condition and degree of pain were both significantly related to the SF-36, BASDAI, BASFI, and MAF scores. CONCLUSION: This study shows that both reduced spinal mobility and radiographic changes in the vertebral body may have a predictive value for pulmonary impairment in patients with AS. Likewise, pain and perceived physical condition may play an important role in the QOL, functional capacity, and fatigue level of these patients.

Evaluation of acute radiation effects on mandibular movements of patients with head and neck cancer / Avaliação dos efeitos agudos da radioterapia sobre os movimentos mandibulares de pacientes com câncer de cabeça e pescoço

OBJECTIVES: To evaluate radiotherapy effects (RT) on mandibular movements of patients with head and neck cancer (H&NC) and associate them to the variables: functional capacity, radiation field, disease staging, type of feeding, concomitant chemotherapy and total dose of RT. METHODS: Twenty-six patients with H&NC were followed up at the RT service. Physical examination was performed in 3 follow up time points: before the beginning of RT (T0), between 14th and 17th session of RT (T1) and after the last session of RT (T2). The physical examination consisted of the assessment of the following variables: mouth opening without pain (MO), maximum mouth opening (MMO), right lateral excursion (RLE), left lateral excursion (LLE) and protrusion (PR) of the jaw. The feeding type and the Karnofsky Performance Status Scale (KPS) were evaluated in each follow up time point. Data with regards to the tumor lesion and the RT were collected from the patient's clinical notes. RESULTS: There was a statistical significant reduction in the values of MO (p=0.006), MMO (p=0.001), LLE (p=0.006) and KPS (p=0.001). There was significant a statistical association among the reduction in KPS and decreased measure of MO (r=0.390, p=0.048) and MMO (r=0.435, p=0.026). The mouth and oropharynx radiation fields when combined showed a significant reduction for both the measure of MO (p=0.005) and for MMO (p=0.004). Patients who used nasoenteric tube feeding (NTF) had greater reduction in the measurement of MMO (p=0.031). The remaining variables showed no statistically significant difference. CONCLUSION: Patients with H&NC present reduction of the measures of MO and MMO during the RT, especially if they present reduced functional capacity, have radiation in the mouth and oropharynx fields and used NTF.

OBJETIVOS: Avaliar os efeitos da radioterapia (RT) sobre os movimentos mandibulares de pacientes com câncer de cabeça e pescoço (CCeP) e associá-los às variáveis: capacidade funcional, campo de radiação, estadiamento da doença, tipo de alimentação, quimioterapia concomitante e dose total de RT. MÉTODOS: Vinte e seis pacientes com CCeP foram acompanhados em um serviço de RT. O exame físico ocorreu em três momentos: antes do início da RT (M0), entre a 14º e 17º sessão (M1) e após a última sessão de RT (M2) para verificação de variáveis, como: abertura bucal sem dor (AB), abertura bucal máxima (ABm), excursão lateral direita (EXd), excursão lateral esquerda (EXe) e protrusão (PR) da mandíbula. O tipo de alimentação e a Escala de Karnofsky (EK) foram reavaliados em cada momento. Dados a respeito da lesão tumoral e RT foram coletados do prontuário do paciente. RESULTADOS: Houve redução significativa nos valores de AB (p=0,006), ABm (p=0,001), EXe (p=0,006) e EK (p=0,001). Houve associação estatisticamente significativa entre a redução na EK e a diminuição de AB (r=0,390; p=0,048) e de ABm (r=0,435; p=0,026). Os campos de radiação da boca e orofaringe, quando agrupados, apresentaram redução significativa tanto para a medida de AB (p=0,005) quanto para ABm (p=0,004). Os pacientes que utilizaram sonda nasoentérica (SNE) apresentaram maior redução da medida de ABm (p=0,031). As demais variáveis não apresentaram diferença estatisticamente significativa. CONCLUSÃO: Os pacientes com CCeP apresentam redução das medidas de AB e ABm no decorrer da RT, principalmente se apresentarem redução da capacidade funcional, tiverem irradiação para os campos da boca e orofaringe e fizerem uso de SNE.

Reavaliação do ombro doloroso em atletas de beisebol após tratamento conservador / Reassessment of painful shoulders among baseball players after conservative treatment

OBJETIVO: O objetivo deste trabalho foi avaliar os resultados da reabilitação nos jogadores de beisebol que possuíam dor e déficit de rotação medial no ombro. MÉTODOS: Dos 55 atletas avaliados no período de abril a junho de 2009, observou-se que 20 atletas tinham dor em algum momento do arremesso. Eles foram orientados a realizar um programa de reabilitação com exercícios para alongamento da cápsula posterior e reforço dos músculos da cintura escapular, especialmente os rotadores laterais. Dezoito pacientes seguiram as orientações, dois perderam o seguimento. Os parâmetros avaliados foram: dor, amplitude de movimento e força pré e pós o término do programa. RESULTADOS: Na avaliação final, em comparação com a inicial, observamos: aumento em média da elevação de 10º (p = 0,001), de três níveis vertebrais da rotação medial (p < 0,001), aumento de 20º da rotação medial a 90º de abdução (p < 0,001) e um aumento de 26º do arco de rotação (p < 0,001). Com relação à força, foi evidente a melhora da força de elevação com aumento de 3kgf (p = 0,002) e da força de rotação lateral com aumento de 1kgf (p = 0,020). Dos 18 atletas estudados, a dor melhorou em 16, dois atletas permaneceram com dor e foram submetidos à ressonância magnética, na qual foram evidenciadas lesões de tratamento cirúrgico. CONCLUSÃO: O programa de reabilitação realizado com os jogadores de beisebol foi efetivo, possibilitando aumento da rotação medial, da elevação, do arco de rotação e das forças de elevação e rotação lateral, consequentemente havendo melhora da dor na maioria dos atletas.

OBJECTIVE: The objective of this study was to evaluate the rehabilitation results among baseball players who presented pain and medial rotation deficit in their shoulders. METHODS: Out of 55 baseball players assessed between April and June 2009, it was observed that 20 presented pain at some instant during throwing movements. They were advised to undergo a rehabilitation program with exercises to stretch the posterior capsule and reinforce the muscles of the scapular belt, especially the lateral rotators. Eighteen patients followed the advice, while two were lost from the follow-up. The parameters evaluated were: pain, range of motion, strength before the program and strength after the end of the program. RESULTS: Comparing the initial and final assessments, we observed mean increases as follows: 10º of elevation (p = 0.001); three vertebral levels of medial rotation (p < 0.001); 20º of medial rotation at 90º abduction (p < 0.001); and 26º of range of motion (p < 0.001). Regarding strength, elevation force increased by 3 kgf (p = 0.002) and lateral rotation force increased by 1 kgf (p = 0.020). Out of the 18 baseball players studied, the pain level improved in 16, while two continued to present pain and underwent magnetic resonance imaging, which showed lesions for surgical treatment. CONCLUSION: The rehabilitation program conducted among the baseball players was effective and enabled increases in medial rotation, elevation, range of motion and strength of elevation and lateral rotation, consequently producing pain improvements in most of the players.

Concordância entre os critérios para flexibilidade de crianças e adolescentes estabelecidos pela physical best e fitnessgram / Agreement between the criteria for children and adolescents´flexibility established by the physical best and the fitnessgram

O objetivo deste estudo foi verificar a concordância entre dois critérios para flexibilidade de crianças e adolescentes, bem como entre os testes utilizados. A amostra foi composta por 59 meninos e 54 meninas, com idades entre oito e dezesseis anos, de uma mesma escola estadual de Londrina, Paraná - Brasil. Na coleta dos dados foram utilizados o Teste de "Sentar-e-alcançar" (PHYSICAL BEST) e o de "Sentar-e-alcançar" alternado (FITNESSGRAM) em um banco de dimensões específicas. Os resultados indicaram uma concordância moderada entre os critérios para meninas (K=0,594, P<0,001) e boa para os meninos (K=0,619, P<0,001). O atendimento dos critérios foi menor entre os meninos com o uso da PHYSICAL BEST. A concordância dos resultados nos testes esteve dentro de limites aceitáveis (média das diferenças de -0,38 a 1,38 cm), e foi verificada correlação de forte a muito forte (r=0,844 a r=0,914). A classificação nos critérios e os resultados obtidos nos testes parecem semelhantes.

The purpose of this study was to verify the agreement between two criteria for flexibility on children and adolescents and between the tests results. The sample involved 59 boys and 54 girls in the age range from 8 to 16 years old, belonging to the same elementary school from the city of Londrina, Parana, Brazil. The data collection used the "Sit-and-Reach" Test (PHYSICAL BEST) and the Back Saver "Sit-and-Reach" Test (FITNESSGRAM) using a bench with specific dimensions. The results indicated a moderate agreement level between the criteria for girls (K=0.594, P<0.001) and good for boys (K=0.619, P<0,001). The passing rates of the criteria were lower in boys using the PHYSICAL BEST. The agreement of tests results were within acceptable levels (mean difference of -0.38 to 1.38 cm) and it were found a strong to very strong relationship (r=0.844 to r=0.914). The criteria classification and the obtained results in the tests were similar.
