ABSTRACT
Introducción: la medición del índice tobillo-brazo (ITB) es una prueba de primera línea y con alta precisión diagnóstica para detectar la enfermedad vascular periférica (EVP). El método Doppler, considerado el estándar de oro, requiere del dispositivo y de un operador capacitado, lo que limita su uso en la atención primaria. Como alternativa, un método oscilométrico que emplea un dispositivo de presión arterial automático es una prueba simple y accesible que podría minimizar los sesgos del observador y eliminar la necesidad de capacitación especial. Objetivos: validar la capacidad diagnóstica de un dispositivo oscilométrico automatizado frente al método Doppler para la medición del ITB. Materiales y métodos: se incluyeron pacientes con diabetes mellitus tipo 1 y 2 (DM1 y DM2), mayores de 50 años, con uno o más factores de riesgo cardiovascular. Luego de que los pacientes permanecieran 5 minutos acostados, se registró la presión arterial sistólica (PAS) con tensiómetro Welch Allyn DS 45-11 y Doppler Vascular Contec Sonoline B 8 Mhz en ambas arterias tibiales posteriores y en arteria braquial derecha. Posteriormente se realizaron los mismos registros con monitor de presión arterial automático modelo Omrom HEM-7130. Se calculó el ITB de cada miembro inferior y las capacidades diagnósticas (sensibilidad [S-, especificidad [E], concordancia por coeficiente kappa, valor predictivo positivo [VPP] y valor predictivo negativo [VPN]) del método oscilométrico para detectar un ITB patológico por Doppler (≤0,90). Resultados: se evaluaron 66 pacientes, 52 varones y 14 mujeres, 7 con DM1 y 59 con DM2, 69 años de edad (DS 9,8), con una antigüedad de la DM de 18,05 años (DS 12,01). La prevalencia de EVP detectada por Doppler (ITB ≤0,90) fue del 16,7% (IC 95% 9,9-23,4). El método oscilométrico para detectar un ITB ≤0,90 por Doppler mostró una S del 72,7% (IC 95% 51,8-93,6), una E del 96,3% (IC 95% 92,4-100), una concordancia del 92,4% (IC 95% 87,5-97,3), un VPP del 80,0% (IC 95% 59,9-100) y un VPN del 94,6% (IC 95% 90,0-99,3). Conclusiones: el alto VPN hallado (condición esencial para un método de screening) significa que si el método oscilométrico da un ITB >0,90, hay un 94,6% de posibilidad de que el ITB por Doppler no sea ≤0,90. El VPP de 80% encontrado significa que si el ITB oscilométrico es ≤0,90, hay un 80% de posibilidad de que el ITB Doppler sea verdaderamente ≤0,90. Por lo tanto, consideramos que la simple medición del ITB con el método oscilométrico podría recomendarse en la atención primaria, donde se requieren métodos rápidos, fáciles y confiables.
Introduction: the measurement of the ankle-brachial index (ABI) is a first-line test with high diagnostic accuracy for the detection of peripheral vascular disease. The Doppler method, considered the gold standard, requires the device and a trained operator, which limits its use in primary care. Alternatively, an oscillometric method using an automated blood pressure device is a simple and affordable test that could minimize observer bias and eliminate the need for special training. Objectives: to validate the diagnostic capacity of an automated oscillometric device against the Doppler method for ABI measurement. Materials and methods: diabetes mellitus type 1 and 2 (DM1 and DM2) patients older than 50 years with 1 or more cardiovascular risk factors were included. After 5 minutes lying down, SBP was recorded with a Welch Allyn DS 45-11 sphygmomanometer and Contec Sonoline B 8 Mhz Vascular Doppler in both posterior tibial arteries and in the right brachial artery. Subsequently, the same recordings were made with an Automatic Blood Pressure Monitor Model Omrom HEM-7130. The ABI of each lower limb and the diagnostic capabilities (sensitivity [S], specificity [E], concordance by kappa coefficient, positive predictive value [PPV] and negative predictive value [NPV] of the oscillometric method to detect a pathological ABI were calculated by Doppler (≤0.90). Results: 66 patients were evaluated, 52 men and 14 women, 7 DM1 and 59 DM2, 69 years old (SD 9.8) with a history of diabetes of 18.05 years (SD 12.01). The prevalence of PVD detected by Doppler (ABI ≤0.90) was 16.7% (95% CI 9.9-23.4). The oscillometric method to detect an ABI ≤0.90 by Doppler showed an S of 72.7% (95% CI 51.8-93.6), an E of 96.3% (95% CI 92.4-100), a concordance of 92.4% (95% CI 87.597.3), a PPV of 80.0% (95% CI 59.9-100) and a NPV of 94.6% (95% CI 90 .0-99.3). Conclusions: the high NPV found (essential condition for a screening method) means that if the oscillometric method gives an ABI >0.90, there is a 94.6% chance that the Doppler ABI is not ≤0.90. The PPV of 80% found means that if the oscillometric ABI is ≤0.90, there is an 80% chance that the Doppler ABI is truly ≤0.90. Therefore, we consider that the simple measurement of ABI with the oscillometric method could be recommended in primary care, where fast, easy and reliable methods are adequate.

An 82-year-old patient underwent a left transfemoral amputation due to a malignant soft tissue tumor. He developed symptoms of chest pain and hypoxia on the 32nd day after the operation. These symptoms were caused by deep venous thrombosis (DVT) of the stump and acute pulmonary thromboembolism (PTE), for which he was treated with anticoagulant therapy. Shortly after treatment he could resume a rehabilitation therapy. Patients with a lower extremity amputation have a higher risk of developing a DVT because of immobility and increased venous pooling in the residual limb. Even with a short stump as in this case, it is important to actively train the range of motion of the joint and try to prevent DVT.

Abstract Objectives: The aim of this study was to evaluate the effect of STS resection in the thigh on MS and the HRQoL. Methods: Fourteen adults patients with STS in the thigh who underwent wide resection and limb preservation were evaluated. The patients were submitted to the Mini-Mental State Examination (MMSE). A hand-held dynamometer was used to measure the MS the flexors, adductors, abductors, and extensors muscles of the operated and non-operated thighs and between the dominant and non-dominant operated sides. The Musculoskeletal Tumor Society (MSTS) and Short Form Health Survey-36 (SF-36) questionnaires were applied to quantify the psychometric properties of the HRQoL. The data were submitted to statistical analysis using the Wilcoxon test (MS), and Mann-Whitney and Spearman correlation (MSTS and SF-36) (α = 0.05). Results: There was no significant difference in MS between the operated side and the non-operated side, and between the dominant and non-dominant operated side (ρ > 0.05). The MSTS presented a significant difference in the emotional acceptance for patients submitted to radiotherapy (ρ = 0.029). The SF-36 showed significant differences in the emotional aspect for patients submitted to chemotherapy (ρ = 0.027) and in the social aspect between the dominant and non-dominant operated side (ρ = 0.024). Conclusions: The HRQoL of adult patients is hampered after the treatment of STS even when MS is maintained.
ABSTRACT
ABSTRACT Introduction: Load reduction using the repetition maximum (RM) method may be necessary to promote higher numbers of repetitions, and consequently, higher total volume, time under tension, and perceived exertion ratings. Objective: To compare the effects of different leg press exercise loads on number of repetitions, total volume, time under tension, and perceived exertion. Methods: Eighteen women university students (23.9 ± 3.8 years) performed two experimental sessions with 90% and 100% of 10-12 RM in a balanced crossover design. Results: The number of repetitions of the second and third sets, the total volume, and time under tension at 90% of 10-12 RM was statistically higher than at 100% of 10-12 RM ( p < 0.05). The perceived exertion of the first and second sets and the training load (perceived exertion x duration of sessions) were higher at 100% of the 10-12 RM session ( p < 0.05). Conclusion: A small reduction in load results in a greater number of repetitions, total volume, and time under tension. The session with the higher load appeared to induce higher perceived exertion and training load. Thus, scientists and coaches might consider lower loads to maximize the number of repetitions, total volume, and time under tension, which may cause greater long-term muscular adaptations. Level of evidence II; Comparative prospective study.
RESUMEN Introducción: La reducción de la carga por el método de las repeticiones máximas (RM) puede ser necesaria para promover un mayor número de repeticiones y, consecuentemente, un mayor volumen total, tiempo bajo tensión y calificaciones del esfuerzo percibido. Objetivo: Comparar los efectos de diferentes cargas del ejercicio de prensa de piernas sobre el número de repeticiones, volumen, tiempo bajo tensión y esfuerzo percibido. Métodos: Dieciocho estudiantes universitarios (23,9 ± 3,8 años) realizaron dos sesiones experimentales con el 90% y el 100% de 10-12 RM en un diseño trasversal equilibrado. Resultados: El número de repeticiones de la segunda y tercera serie, el volumen total y el tiempo bajo tensión al 90% de 10-12 RM fue estadísticamente mayor que al 100% de 10-12 RM (p < 0,05). El esfuerzo percibido de la primera y segunda serie y la carga de entrenamiento (esfuerzo percibido x duración de las sesiones) fueron superiores en la sesión realizada al 100% de 10-12 RM (p < 0,05). Conclusión: Una pequeña reducción de la carga da lugar a un mayor número de repeticiones, volumen total y tiempo bajo tensión. La sesión con mayor carga indujo un mayor esfuerzo percibido y carga de entrenamiento. Por lo tanto, los científicos y entrenadores pueden considerar cargas más bajas para maximizar el número de repeticiones, el volumen total y el tiempo bajo tensión, lo que puede causar mayores adaptaciones musculares a largo plazo. Nivel de evidencia II; Estudio prospectivo comparativo.

Métodos: Dezoito universitárias (23,9 ± 3,8 anos) realizaram duas sessões experimentais com 90% e 100% de 10-12 RM em desenho transversal balanceado. Resultados: O número de repetições da segunda e terceira séries, volume total e tempo sob tensão a 90% de 10-12 RM foi estatisticamente maior do que a 100% de 10-12 RM (p < 0,05). A percepção do esforço da primeira e segunda séries e a carga de treinamento (percepção do esforço x duração das sessões) foram maiores na sessão realizada com 100% de 10-12 RM (p < 0,05). Conclusão: Uma pequena redução da carga resulta em maior número de repetições, volume total e tempo sob tensão. A sessão com maior carga induziu maior percepção do esforço e carga de treinamento. Assim, cientistas e treinadores podem considerar cargas menores para maximizar o número de repetições, o volume total e o tempo sob tensão, o que pode causar maiores adaptações musculares a longo prazo.

ABSTRACT
ObjectiveTo explore the effects of different intensity of wearable lower limb rehabilitation robot-assisted training on walking function, lower limb motor function, balance function and functional independence of stroke patients. MethodsFrom November, 2021 to December, 2022, 60 stroke patients hospitalized in Beijing Bo'ai Hospital were randomly divided into control group (n = 20), observation group 1 (n = 20) and observation group 2 (n = 20). All the groups received routine rehabilitation, while the control group received routine walking training 30 minutes a day, the observation group 1 received wearable lower limb rehabilitation robot-assisted training 30 minutes a day, and the observation group 2 received wearable lower limb rehabilitation robot-assisted training 60 minutes a day, for four weeks. They were assessed with Functional Ambulation Category scale (FAC), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Berg Balance Scale (BBS) and Rivermead Mobility Index (RMI) before and after treatment. ResultsOne case in the observation group 1 and three cases in the observation group 2 dropped down. The FAC, FMA-LE, BBS and RMI scores improved in all the three groups after treatment (|Z| > 3.448, |t| > 8.102, P < 0.001), and there was no significant difference in all the indexes among the three groups (|H| < 4.643, F = 1.454, P > 0.05); however, the improvement of BBS score was more in the observation group 1 than in the control group (P < 0.05), and the improvement of all the indexes was more in the observation group 2 than in the control group (P < 0.05). ConclusionThe wearable lower limb rehabilitation robot-assisted training may promote the recovery of walking function, lower limb motor function, balance function and functional independence of stroke patients, and high-intensity training seems to be more effective.

ConclusionCombining with video-based mirror therapy could facilitate to improve the lower limb motor function and balance ability of stroke patients at recovery stage.
ABSTRACT
ObjectiveTo observe the characteristics of gait symmetry and its influencing factors in patients with incomplete spinal cord injury (ISCI). MethodsFrom May, 2018 to November, 2021, 34 patients with ISCI in Beijing Bo'ai Hospital were divided into symmetrical injury of lower limb (SI) group and asymmetrical injury of lower limb (ASI) group according to the lower extremities motor score (LEMS). Three dimensional motion acquisition system and plantar pressure acquisition system were used for gait test. The symmetry indexes of step length, stance time and swing time were caculated. ResultsThe symmetry indexes of step length, stance time and swing time were significant lower in SI group than in ASI group (|t| > 2.619, P < 0.01). Stance time and swing time significantly correlated to the difference of bilateral LEMS in ASI group (r > 0.468, P < 0.01). Discriminant analysis showed that gait parameter equations were different for patients with different symmetry of lower limb injuries. ConclusionThe symmetry of lower limb motor function impacts gait symmetry for patients with ISCI, especially the difference value of bilateral total LEMS. Gait parameters can be used to determine the symmetry of lower limb injury in patients with ISCI.
ABSTRACT
Objective:To observe any effect of combining extracorporeal shock wave stimulation with proprioceptive neuromuscular facilitation (PNF) on the lower limb motor function of stroke survivors with foot drop.Methods:Thirty-six stroke survivors with foot drop were randomly divided into an extracorporeal shock wave group, a PNF group and a combination group, each of 12. The extracorporeal shock wave group and PNF group were given those therapies alone, while the combination group was provided with both. The extracorporeal shock wave therapy protocol was 2000 times on each muscle at an intensity of 2.5 bar and a frequency of 10Hz, twice a week for 4 weeks, while the PNF was provided at least 3 times per week for 4 weeks. Before and after the intervention, all of the participants were evaluated using the modified Ashworth scale (MAS), the 10-metre walk test (10 MWT) and the Fugl-Meyer lower limb motor function scale (FMA). Active range of the ankle joint and toe out angle were also observed.Results:After the intervention the lower limb muscle tone had decreased significantly in 8 of the PNF group members and in 9 of those in the extracorporeal shock wave group, but it has decreased significantly in all 12 members of the combination group. And the average magnitude of the improvement was also significantly greater in the combination group than in the other two groups. Moreover, significant differences were observed in the active range of the ankle joint after the treatment in the combination group, but not in the other two groups. After the intervention the average 10 MWT times and FMA scores of the PNF and combination groups had improved significantly, but not those of the extracorporeal shock wave group, but significant improvement in toe out angles was observed in all three groups, though the average improvement in the combination group was significantly greater than in the other 2 groups.Conclusion:Combining extracorporeal shock waves with PNF can effectively improve the lower limb motor function of stroke survivors with foot drop.
ABSTRACT
Objective:To explore any differential effect of training wearing a unilateral exoskeleton on the lower-limb motor function of stroke survivors.Methods:Forty stroke survivors were randomly divided into an exoskeleton group ( n=20) and a control group ( n=20). The control group performed conventional lower extremity exercise training while the exoskeleton group received exoskeleton-assisted lower-limb physical therapy. Each participant received eighteen 40-minute training sessions over three weeks. Before and after the intervention, the walking ability, lower-limb function, balance and ability in the activities of daily living of both groups were evaluated. Integrated electromyography (iEMG) of the rectus femoris and tibialis anterior of both legs was also recorded during sit-to-stand transitions to assess the activation of the affected muscles and the symmetry of bilateral muscle activation. Results:After the three weeks, significant improvement was observed in all of the measurements in both groups, but with the exoskeleton group scoring significantly better on average in functional ambulation category grading (1.63±0.72). Both groups′ iEMGs had also improved significantly compared with before treatment, but the exoskeleton group′s average result was by that time significantly better than the control group′s average.Conclusions:A wearable exoskeleton can effectively improve the rehabilitation of walking, lower limb movement, balance and skill in the activities of daily living of persons with subacute stroke. It better activates the affected lower limb muscles and improves the symmetry of bilateral lower limb muscle activation.
ABSTRACT
ObjectiveTo summarize and analyze the protocols of repetitive transcranial magnetic stimulation (rTMS) in the treatment of post-stroke lower limb dysfunction. MethodsLiterature about rTMS for lower limb dysfunction of patients post stroke were retrieved from Web of Science, PubMed, CNKI, and Wanfang Data from inception to August 17, 2022. The quality of the literature was evaluated with Physiotherapy Evidence Database (PEDro) scale. Literature quality, data extraction and scoping review were performed by two researchers. ResultsA total of 21 studies were included, in which 20 studies suggested that rTMS treatment could promote the recovery of lower limb motor function after stroke. One study showed negative result. rTMS interventions were reported safe, with no serious adverse reactions. There were great heterogeneity in the demographic and clinical information, study protocols, stimulation parameters, coil types, targets of stimulation, and motor-evoked potential measurement in the included studies. ConclusionThe future protocols of rTMS need to be combined with stroke stage and severity of injury. There is a demand for more real vs. sham rTMS studies, reporting similar designs with sufficient information, to achieve a significant level of evidence regarding the use of rTMS in post-stroke patients.

ABSTRACT
RESUMEN El test de salto vertical es muy interesante como prueba física, en el voleibol moderno, para valorar la potencia de piernas, ya que de esa manera el preparador físico puede planificar un programa de fuerza-velocidad con la intención de mejorar sus prestaciones físicas en el terreno de juego. El voleibol es un deporte que se caracteriza por acciones de juego de corta duración y de gran intensidad, alternadas por cortos períodos de descanso. Esto hace pensar en la necesidad de desarrollar en las voleibolistas una gran potencia, fundamentalmente en los miembros inferiores, aspectos que fue evaluado a diez atletas de voleibol categoría sub-18 de la Escuela Nacional de voleibol por métodos indirectos Lewis y Harman, a las que se les realizó un estudio transversal en la etapa de preparación física general. Este trabajo tuvo como objetivo comparar los niveles de potencia de miembros inferiores por ambos test en un periodo de seis semanas. Como métodos empíricos se utilizaron la medición y los test indirectos para evaluar la potencia de salto. Se obtienen resultados satisfactorios en ambos test, fundamentalmente después de someter a las atletas a un sistema de ejercicios que se muestran con mayor nivel de información para el entrenador los valores de la potencia de Harman, ya que en este tiene en cuenta la acción de la aceleración gravitatoria que debe vencer en la fase de despegue. A partir de los resultados, se brindaron sugerencias individuales para el entrenamiento de dichos atletas.

ABSTRACT The vertical jump test is very interesting as a test physical in modern volleyball to assess the power of the legs, since in this way the physical trainer can plan a strength-speed program with the intention of improving their physical performance on the game field. Volleyball is a sport that is characterized by short duration and high intensity game actions, alternated by short periods of rest. This suggests the need to develop great power in volleyball female players, fundamentally in the lower limbs, aspects that were evaluated on ten volleyball athletes in the sub-18 category of the National Volleyball School by indirect methods Lewis and Harman, to whom a cross-sectional study was carried out in the stage of general physical preparation. The objective of this work was to compare the power levels of the lower limbs by both tests in a period of six weeks. As empirical methods, measurement and indirect tests were used to evaluate jumping power. Satisfactory results are obtained in both tests, fundamentally after subjecting the athletes to a system of exercises that show the Harman power values with a higher level of information for the coach, since in this it takes into account the action of the gravitational acceleration that must be overcome in the take-off phase. Based on the results, individual suggestions for the training of these athletes were provided.
ABSTRACT
Background: Aging is a gradual, life-long process and highly variable, characterized by a progressive and cumulative generalized impairment of physiological functions which in turn reduces functional performance and disturbs ADL's & may lead to significant impact on core & lower limb muscles, which are important in functioning. Thus, the study aimed at assessing correlation amongst the core & lower limb muscles and functional status. Methods and procedures: 84 participants between 70-79 years of age (Male:Female = 1:1) were assessed for core strength, Lower limb strength and functional mobility using pressure biofeedback, five times sit to stand and timed up and go test respectively and data was tabulated & analyzed further in SPSS. Results: Spearman's correlation was used in this study which showed significant positive correlation between core strength and lower limb strength with lower limb functional status. (r(Core)=0.813, r(5SST) =0.893; p(Core)=0.00, p(5SST) =0.00) Discussion: Optimal core stability helps maintain the center of gravity within the altered base of support and this could be a reason for individuals with good core strength having better functional mobility. Also force of muscle contraction is directly proportional to velocity of movement which is seen reduced in lower limb musculature because of aging in this population. Conclusion: The present study concluded that strong correlation of core strength and lower limb strength with functional mobility exists among middle old elderly population.
