Crecimiento femorotibial en miembros inmovilizados de rata
1986
An experimental study has been carried out using rats stills in the growth stage, whose right hindlimbs have been immobilized. Weekly, during four weeks, the animals were destroyed and measurements taken of the tibias and femurs, establishing that the rate of tibialis growth was higher in the immobilized limb than in the free limb (p. o. 001). The femurs, however, showed a similarity of measurement in both limbs. Our findings show that immobilization of a limb in a functional position is in no way prejudicial to bone growth.
Arm swing during skating at different skiing speeds affects skiing mechanics and performance
2018
Arm swing has been shown to lead to greater maximal speed and movement economy in cross -country skiing. The current study aimed to investigate how arm swing alters skiing mechanics and contributes to performance and acceleration of the athlete’s centre of mass (COM). While skiing on snow seven highly skilled cross -country skiers simulated V2 -alternate skating without using ski poles and with double or single arm swing and without arm swing . During leg push -off the linear momentum of the body increased due to arm swing. Simultaneously, linear momentum of the arm(s) decreased in arm swing trials, indicating a transfer of momentum from arms to the rest of the body and being more prevalent…

Motor unit activation and force production during eccentric, concentric and isometric actions
2002
The aim of the present series of studies is to examine force and myoelectrical activity in human forearm flexors and knee extensors during dynamic and isometric muscle actions. The main purposes are 1) to clarify the methodological issues regarding the measurements of maximal force, EMG and EMG power spectrum in eccentric, concentric and isometric conditions, 2) to examine the motor unit activation patterns during dynamic and isometric actions by following the behavior of the EMG power spectrum and by utilizing selective intramuscular fine wire electrodes, and 3) to examine the effects of fatigue on force production, aEMG and EMG power spectrum in eccentric and concentric actions.
Importance of static adjustment of knee angle to determine saddle height in cycling
2016
Knee flexion angle is used to determine saddle height during pedaling. However, it is unclear if knee flexion angle at upright standing posture affects measures and interpretation of knee flexion angle during cycling. The objective of this study was to assess the importance of adjusting knee angle during pedaling according to the knee angle at upright posture. Seventeen cyclists performed three 10 min cycling trials at different saddle heights to induce knee flexion angles (40º, 30º or 20º when crank was at the 6 o'clock position). Knee flexion angle was determined at the sagittal plane during cycling using a 2D motion analysis system. Alteration of saddle height was performed by subtractin…
Sinovitis villonodular pigmentada difusa: Revisión de 13 casos
1998
Se hace un estudio retrospectivo de trece pacientes con Sinovitis Villonodular pigmentada, seis localizadas en la rodilla, dos en la muñeca y pie, y uno en tobillo, cadera y codo respectivamente. En cinco de los casos existía una afectación del hueso. Se hace una revisión bibliográfica sobre la etiopatogenia, radiología, métodos diagnósticos y tratamiento A retrospective study of thirteen patients with pigmented villonodular synovitis was made. Six cases were localized in the knee, two in the wrist and feet, and one in ankle, hip and elbow. Five case showed bone invasion, the pathogenesis, radiographical appearance, diagnosis and treatment are discussed.
Síndrome del túnel carpiano agudo secundario a cuerpo extraño.
2013
Se presenta un caso de síndrome del túnel carpiano agudo (STCA) secundario a la penetración de una espina de cactus dentro del canal carpiano. El tratamiento consistió en la inmediata liberación del retináculo flexor junto con la extracción del cuerpo extraño. La función del nervio mediano se recuperó inmediatamente. Creemos que es el primer caso publicado de STCA secundario a una espina de cactus. A case of acute carpal tunnel syndrome secondary to spine cactus puncture of the wrist is repor - ted. Treatment consisted of early carpal tunnel release and removal of spine cactus. The median nerve function promptly returned to normal. We believe this is the first report of acute carpal tunnel …
Lattice Boltzmann simulations in microfluidics: probing the boundary condition
2008
In this contribution we summarize our investigations of the effect of boundary slip by utilizing lattice Boltzmann simulations. We investigate fluid flow in hydrophobic and rough microchannels and show that a slip due to hydrophobic interactions increases with increasing hydrophobicity and is independent on the shear rate. If surface roughness is not treated properly while analysing experimental results, a large apparent slip might be measured. We show that the no-slip boundary condition holds in this case if an effective surface position at an intermediate position between peaks and valleys of the surface is considered. Further, we study the effect of microbubbles present on a surface and …
Roturas traumaticas del ligamento colateral medial de la articulacion metacarpo-falangica del pulgar (lesion de stener) : a proposito de 30 casos tra…
1987
Thirty cases of rupture of the ulnar-collateral Iigament of metacarpal phalangeal joint of the thumb (Stener's lesion) are reported. The biomecanics of this ligament and the mechanisms of its rupture as well as the most frequent anatomopatologic types are described. The importance of the surgical treatment and sorne details of its technique are emphasized.
Estudio comparativo de la tecnica de artroplastia total de la articulacion trapezo metacarpiana frente a la artrodesis
1987
The results of seven cases with total prosrhetic replacement of trapezo-metacarpal joint are compared with fourteen cases of arthrodesis of cargo metacarpal joint of the thumb. Indications and complications are analyzed.
