Avaluació de l'esforç submàxim dels flexors dorsals i palmars de canell mitjançant dinamometria isocinètica

El SEC (Suma Excèntric- Concèntric) i sobretot el DEC (Diferència Excèntric-Concèntric) són paràmetres que, ja han sigut demostrats en la literatura, com a vàlids en diferents articulacions i accions, per a identificar esforços submàxims, és a dir, la possible falta de col·laboració, durant la realització de proves de força mitjançant dinamometria isocinètica. Aquest estudi, mitjançant una mostra de 20 individus sans, demostra que el DEC i el SEC són bones eines per detectar la falta de col·laboració en l'avaluació dels flexors dorsals i palmars de canell (articulació prèviament no estudiada) amb dinamometria isocinètica en subjectes sans.El SEC (Suma Excéntrico- Concéntrico) y sobre todo el DEC (Diferencia Excèntric-Concèntric) son parámetros que, ya han sido demostrados en la literatura, como válidos en diferentes articulaciones y acciones, para identificar esfuerzos submáximos, es decir, la posible falta de colaboración, durante la realización de pruebas de fuerza mediante dinamometría isocinética.

La impronta de Pedro Montserrat en el herbario BCN (Universidad de Barcelona)

Pedro Montserrat Recoder (1918-2017) obtuvo la licenciatura en Ciencias Naturales en la Universidad de Barcelona en 1945 y ese mismo año inició su tesis doctoral en la Facultad de Farmacia de dicha universidad, bajo la dirección del profesor T. Mariano Losa. Disfrutaba de una beca del Instituto de Biología Aplicada y tenía a su cargo las prácticas de Fanerogamia de la Facultad de Farmacia. Al año siguiente pasó a ser becario del Instituto Botánico de Barcelona y continuó con la misma docencia en dicha facultad hasta 1950. Profesor y doctorando se plantearon la exploración conjunta de la flora del eje pirenaico-cantábrico y realizaron numerosas expediciones que generaron una ingente cantidad de pliegos. Éstos se conservaron mayoritariamente en el entonces herbario BCF de la Facultad de Farmacia y desde 2001 pasaron a formar parte de las colecciones del herbario BCN, al fusionarse con el BCC de la Facultad de Biología de la misma universidad. Desgraciadamente una parte importante de los pliegos de las campañas de dichos botánicos durante este periodo quedaron solo parcialmente procesados, con sucintas etiquetas “provisionales que por desgracia quedaron como definitivas” (Montserrat, 1994). En estas etiquetas la localidad de recolección suele ser incompleta, también a veces la fecha y raramente figura el recolector. Consciente de ello y para paliar este escollo, en 1983 el mismo P. Montserrat transcribió mecanográficamente los datos de sus libretas de campo en unos utilísimos folios de los que existe copia en el herbario BCN..

Controle postural no envelhecimento: um estudo comparativo entre Brasil e Espanha

O envelhecimento traz consigo alterações nos sistemas sensoriais e músculo-esquelético, que juntos alteram o controle postural dos idosos. O objetivo deste estudo foi o de verificar e comparar o controle postural de idosos da cidade de São Paulo - Brasil, com idosos que vivem em Terrassa (Barcelona)- Espanha. Participaram da pesquisa, 36 idosos brasileiros (69,61±5,3 anos) e 33 idosos espanhóis (69,72±4,6 anos) considerados saudáveis, recrutados a partir de dois serviços de reabilitação. Os voluntários realizaram avaliações pertinentes ao controle postural por meio do teste Timed up and go e bateria de testes de Guralnik. Os dados foram analisados por meio do teste t e os resultados mostram que os grupos são semelhantes quanto a idade e a composição corporal, porém o grupo do Brasil apresentou melhores resultados nas duas avaliações realizadas quando comparado com o grupo da Espanha. Concluise que os indivíduos brasileiros deste estudo apresentaram melhor desempenho na realização dos testes sobre controle postural.Aging cause changes in the sensory and musculoskeletal systems, which together affect the postural control of the elderly. The aim of this study was to assess and compare the postural control of elderly individuals in São Paulo, Brazil, with elderly individuals who live in Terrassa (Barcelona), Spain. A total of 36 elderly Brazilian individu-als (mean age: 69.61 ± 5.3 years) and 33 elderly individuals from Spain (69.72 ± 4.6 years) participated in the study; they were consid-ered to be healthy and were recruited from two rehabilitation services. The volunteers underwent postural control assessment through the Timed Up and Go and the Guralnik Test Battery tests. Data were analyzed using the t test. The results showed that the groups were similar regarding age and body composition, but the group in Brazil showed better results at both evaluations, when compared with the group in Spain. We concluded that Brazilian individuals in this series showed a better performance on the postural control tests

A cross-sectional study comparing strength profile of dorsal and palmar flexor muscles of the wrist in epicondylitis and healthy men

Background: Strength training has been proposed by several authors to treat Lateral Epicondylitis. However, there is still a lack of information concerning muscle weakness and its relationship to imbalances and fatigability of forearm muscles during dynamic conditions in subjects after epicondylitis recovery. Aim: To analyze the relationship between lateral humeral epicondylitis, and forearm muscle strength and fatigue. Setting: Rehabilitation specialized center Population: Cross-sectional study in eight former epicondylitis men free of symptoms and actively working at the moment of the evaluation and eight healthy men volunteers. Methods: Isokinetic tests were performed at different velocities in order to assess strength in concentric and eccentric contractions. Additionally, a long-term concentric test was carried out in order to analyze strength during endurance. The following variables were analyzed: Average torque of dorsal and palmar flexors of the wrist and ratio of agonist/antagonist for non-endurance contractions; length of initial and final plateaus and the slope of average torque decay during the endurance test. Results: In both groups, average torque produced by palmar flexor muscles was higher than that produced by dorsal flexor muscles. Patients showed higher strength in palmar flexor muscles, whereas dorsal flexor strength was similar for both populations. Palmar flexor vs. dorsal flexor ratio was significantly higher in patients for eccentric contractions. Regarding fatigue, results showed that torque decreased earlier in patients. Conclusions and clinical rehabilitation impact: Both palmar flexor force and palmar/dorsal ratio in eccentric exercise were significantly higher in patients. This finding indicates a muscular imbalance in patients underlying the epicondylitis condition. Additionally, former patients fatigued earlier. Findings indicate that muscle imbalances and fatigability might be related to lateral epicondylitis. […]Postprint (published version

Effectiveness of an exercise program on postural control in frail older adults

Background: Exercise programs have proved to be helpful for frail older adults. This study aimed to investigate the effects of an exercise program with a focus on postural control exercises in frail older adults. Method: Twenty-six older adults (76.7 +/- 4.9 years) deemed clinically stable, chosen from the Falls Unit, University Hospital Mutua Terrassa, Barcelona, Spain, participated in this single-group study. Volunteers' postural control was evaluated using the Timed Up and Go test (TUG) and the Guralnik test battery, and their static and dynamic posturography were evaluated using the Synapsys Posturography System (R). These evaluations were performed before and after the intervention program, which included an educational session and two weekly 1-hour sessions over an 8-week period of stretching exercises, proprioception, balance, and motor coordination. Data were analyzed using the Student's t-test or the Wilcoxon test, with a significance level of 5%. Results: The TUG and Guralnik tests did not show significant differences. Concerning static posturography, there was improvement in the base of support (P = 0.006), anteroposterior displacement with eyes open (P = 0.02) and closed (P = 0.03), and the total amplitude of the center of pressure with eyes closed (P = 0.02). Regarding dynamic posturography, a decrease of the oscillation speed in the anteroposterior direction (P = 0.01) was observed in individuals with their eyes open. Conclusion: The program used in this study was safe and was able to promote some improvement in postural control, especially in the anteroposterior direction and in the base of support. However, it is noteworthy that further improvements could be obtained from a program of longer duration and greater frequency
