Publication Open Access The contribution of the tendon electrode to M-wave characteristics in the biceps brachii, vastus lateralis and tibialis anterior(Wiley, 2023) Rodríguez Falces, Javier; Etxaleku, Saioa; Trajano, Gabriel S.; Setuain Chourraut, Igor; Ciencias de la Salud; Ingeniería Eléctrica, Electrónica y de Comunicación; Osasun Zientziak; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio IngeniaritzarenIn some compound muscle action potentials (M waves) recorded using the belly–tendon configuration, the tendon electrode makes a noticeable contribution to the M wave. However, this finding has only been demonstrated in some hand and foot muscles. Here, we assessed the contribution of the tendon potential to the amplitude of the vastus lateralis, biceps brachii and tibialis anterior M waves, and we also examined the role of this tendon potential in the shoulder-like feature appearing in most M waves. M waves were recorded separately at the belly and tendon locations of the vastus lateralis, biceps brachii and tibialis anterior from 38 participants by placing the reference electrode at a distant (contralateral) site. The amplitude of the M waves and the latency of their peaks and shoulders were measured. In the vastus lateralis, the tendon potential was markedly smaller in amplitude (∼75%) compared to the belly M wave (P = 0.001), whereas for the biceps brachii and tibialis anterior, the tendon and belly potentials had comparable amplitudes. In the vastus lateralis, the tendon potential showed a small positive peak coinciding in latency with the shoulder of the belly–tendon M wave, whilst in the biceps brachii and tibialis anterior, the tendon potential showed a clear negative peak which coincided in latency with the shoulder. The tendon potential makes a significant contribution to the belly–tendon M waves of the biceps brachii and tibialis anterior muscles, but little contribution to the vastus lateralis M waves. The shoulder observed in the belly–tendon M wave of the vastus lateralis is caused by the belly potential, the shoulder in the biceps brachii M wave is generated by the tendon potential, whereas the shoulder in the tibialis anterior M wave is caused by both the tendon and belly potentials.Publication Open Access Short-term effects of manipulative treatment versus a therapeutic home exercise protocol for chronic cervical pain: a randomized clinical trial(IOS Press, 2018) Galindez Ibarbengoetxea, Xabier; Setuain Chourraut, Igor; Ramírez Vélez, Robinson; González Izal, Miriam; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun ZientziakBackground: While both manipulative treatment and physical exercises are used to treat cervical pain, it remains unclear which is most effective. Objective: To compare the short-term effects of high-velocity, low-amplitude manipulation techniques (MT) with those of home-exercise (HE) with stretching and low-intensity (10% of max) isometric contractions on pain and function. Methods: Single-blind randomized clinical trial was performed. A total of 27 asymptomatic subjects were randomly assigned to 2 groups: manipulation techniques (MT, n= 13) and home exercise (HE, n= 14). The visual analogue scale (VAS); neck disability index (NDI); pressure pain thresholds; cervical spine range of motion and electromyography during the cranio-cervical flexion test was measured before and one week after the intervention. Results: After the intervention, both groups showed improved (P< 0.05) NDI and VAS scores and flexion in both rotation ranges compared with the pre-intervention values. For the NDI, pain intensity, and neck flexion, the effects sizes were large; for the majority of the other measurements, the effect sizes were small to moderate. The MT group showed significantly better results than the HE group for 2 out of 17 tests. Conclusions: Both interventions improved function and pain after one week, with only marginal between-group differences in favor of MT.Publication Open Access Prediction of sports injuries in football: a recurrent time-to-event approach using regularized Cox models(Springer, 2021) Zumeta-Olaskoaga, Lore; Weigert, Maximilian; Larruskain, Jon; Bikandi Latxaga, Eder; Setuain Chourraut, Igor; Lekue, Josean; Küchenhoff, Helmut; Lee, Dae-Jin; Ciencias de la Salud; Osasun ZientziakData-based methods and statistical models are given special attention to the studyof sports injuries to gain in-depth understanding of its risk factors and mechanisms. The objective of this work is to evaluate the use of shared frailty Cox models forthe prediction of occurring sports injuries, and to compare their performance withdifferent sets of variables selected by several regularized variable selection approaches. The study is motivated by specific characteristics commonly found for sports injury data, that usually include reduced sample size and even fewer number of injuries,coupled with a large number of potentially influential variables. Hence, we conduct asimulation study to address these statistical challenges and to explore regularized Cox model strategies together with shared frailty models in different controlled situations. We show that predictive performance greatly improves as more player observations areavailable. Methods that result in sparse models and favour interpretability, e.g. best subset selection and boosting, are preferred when the sample size is small. We include a real case study of injuries of female football players of a Spanish football club.Publication Open Access Diferencias en el rendimiento en el salto entre jugadores de balomnano de élite con o sin reconstrucción previa del ligamento cruzado anterior de la rodilla (LCA)(2012) Setuain Chourraut, Igor; Izquierdo Redín, Mikel; Escuela Universitaria de Estudios Sanitarios; Osasun Ikasketen Unibertsitate EskolaEl balonmano es considerado uno de los deportes más exigentes para la articulación de la rodilla, donde la incidencia lesión del LCA es relativamente alta en comparación con otras disciplinas deportivas. No resulta infrecuente la convivencia con déficits de fuerza y control neuromuscular en atletas que han sufrido la lesión del LCA. La medición de variables relativas al rendimiento en el salto podría resultar de gran ayuda durante el proceso rehabilitador para garantizar una óptima vuelta a la competición y ayudar a minimizar los dramáticos y costosos episodios de recaída que asocia esta lesión en jugadores de balonmano de élite. OBJETIVO e HIPOTESIS: Examinar las diferencias entre los atletas previamente lesionados del LCA y atletas sanos de control, en la ejecución de una batería de saltos verticales y horizontales, analizando variables de estudio del salto como el tiempo de contacto, tiempo de vuelo potencia mecánica y distancia alcanzada. La hipótesis del estudio sostiene que los atletas previamente lesionados del LCA, mostrarán déficits en relación a las variables sometidas a estudio a pesar de haber completado su proceso recuperador y estar totalmente integrados en la vuelta a la competición. MATERIALES Y MÉTODOS: 13 Hombres y 20 mujeres jugadores de balonmano de élite (6 previamente lesionados y reconstruidos del LCA y 7 atletas sanos de control en el grupo de los hombres y 6 previamente lesionadas y reconstruidas del LCA y 14 atletas sanas de control en el grupo de las mujeres respectivamente)fueron evaluados utilizando una batería de saltos validad previamente que incluye el drop jump bilateral, el drop jump unilateral, salto contramovimiento unilateral, el triple salto de longitud y el triple salto cruzado de longitud. Durante la ejecución de dicha batería se registraron la altura (m), el tiempo de vuelo time (s), el tiempo de contacto (s), la potencia mecánica desarrollada (W·kg-1) y la distancia alcanzada (m). Para los saltos unilaterales, la comparación se realizó entre la pierna lesionada y la pierna dominante de los controles sanos. Para los saltos bilaterales, en cambió la comparación se realizó entre los sujetos lesionados y los sanos. Para el tratamiento estadístico de los datos, se calcularon las medias y desviaciones estándar de cada variable en cada grupo, analizando los resultados de cada sexo por separado. La comparación de los resultados obtenidos en cada grupo se realizará mediante la prueba T –test para muestras independientes. El programa estadístico utilizado será el SPSS v16.0 (Chicago, IL). RESULTADOS: Las atletas previamente lesionadas del LCA, demostraron menor tiempo de contacto en el drop jump bilateral (0,393 vs 0,541 s; P<0.001) así como una menor distancia alcanzada en el triple salto de longitud (0,382 vs 0,435 m; P<0.05) con respecto al grupo atletas sanas de control. Los atletas previamente lesionados del LCA, demostraron menor potencia mecánica desarrollada en el drop jump unilateral (11,06 vs. 17,43 W·kg-1; P<0.05) en la extremidad afectada con respecto al grupo de control. No se encontraron diferencias significativas en el resto de variables sometidas a estudio. CONCLUSION: Los jugadores con antecedente de lesión del LCA, podrían arrastrar secuelas funcionales aún después de haber vuelto a la competición, aumentando de esta manera el riesgo de recaída. El reestablecimiento de la simetría entre la extremidad sana y la lesionada, podría ayudar a reducir el riesgo de recaída de la lesión del LCA en jugadores de balonmano de élite.Publication Open Access Validation and application of two new core stability tests in professional football(MDPI, 2020) Etxaleku, Saioa; Izquierdo Redín, Mikel; Bikandi Latxaga, Eder; García Arroyo, Jaime; Setuain Chourraut, Igor; Ciencias de la Salud; Osasun ZientziakThe purpose of the first study was to validate two newly proposed core stability tests; Prone Plank test (PPT) and Closed Kinetic Chain test (CCT), for evaluating the strength of the body core. Subsequently, these tests were employed in a longitudinal prospective study implementing a core stability training program with a professional Spanish football team. For the validation study, 22 physically active men (Tegner Scale 6-7) performed three trials of the PPT and CCT tests in two different testing sessions separated by one week. In the longitudinal study, 13 male professional football players were equally evaluated (PPT and CCT) before and after the competitive session in which they completed a core training program. Intra-/intersession, and intertester, reliability was analyzed. PPT and CCT demonstrated excellent to good test-retest reliability and acceptable error measurement (ICCs for intratester and intrasession reliability ranged from 0.77 to 0.94 for the PPT, and 0.8-0.9 for the CCT) in all but one of the testing conditions (female tester for CCT test; ICC = 0.38). Significant improvements on core strength were found from pre to post evaluation in both the PPT (p < 0.01) and CCT (p < 0.01) after the implementation of a core training program in professional football players.Publication Open Access A protocol for a new methodological model for work-related shoulder complex injuries: from diagnosis to rehabilitation(BioMed Central, 2017) Setuain Chourraut, Igor; González Izal, Miriam; Paularena, Ainara; Luque, José Luis; Andersen, Lars L.; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun ZientziakBackground: Work-related injuries of the shoulder complex represent a challenge for clinicians because of the large variety of clinical entities involved and the broad anatomic structures that can be affected. Furthermore, commonly performed orthopedic tests have demonstrated limited accuracy for diagnosing the injury despite considerable research efforts. The aim of this study protocol is therefore to describe a comprehensive approach integrating both a clinical- and functional status-based pathology and an adapted rehabilitation prescription. Methods/Design: A longitudinal cohort study will be performed at the Department of Rehabilitation and Medical Assistance of a mutual insurance society for work-related injury management in Spain (Mutua Navarra, Pamplona, Navarra Spain). Patients will be attended by an occupational physician who specializes in work-related injuries and is part of the project team that will systematically visit all the participants. After the medical diagnosis and any requested supplementary evaluations (i.e., radiological examinations), the patients will be referred to the rehabilitation service. Before the physiotherapeutic rehabilitation program is initiated, the patients will undergo a comprehensive functional screening at the biomechanics laboratory. Using a decision-making scheme, the identified functional deficits will be used to customize the individual rehabilitation plan. Discussion: The proposed objective criteria-based shoulder diagnosis and rehabilitation model could be a new effective strategy for minimizing the time required to regain functional capacity and recover from symptoms among patients with work-related shoulder injuries.Publication Open Access Sprint mechanics evaluation using inertial sensor-based technology: a laboratory validation study(Wiley, 2018) Setuain Chourraut, Igor; Lecumberri Villamediana, Pablo; Ahtiainen, J. P.; Mero, A. A.; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun ZientziakAdvances in micro‐electromechanical systems have turned magnetic inertial measurement units (MIMUs) into a suitable tool for vertical jumping biomechanical evaluation. Thus, this study aimed to determine whether appropriate reliability and agreement reports could also be obtained when analyzing 20‐m sprint mechanics. Four bouts of 20‐m sprints were evaluated to determine whether the data provided by a MIMU placed at the lumbar spine could reliably assess sprint mechanics and to examine the validity of the MIMU sensor compared to force plate recordings. Maximal power (P0), force (F0), and velocity (V0), as well as other mechanical determinants of sprint performance associated with the force‐velocity, power‐velocity, and ratio of forces‐velocity, such as applied horizontal force loss (Sfv) and decrease in ratio of forces (Drf), were calculated and compared between instrumentations. Extremely large‐to‐very large correlation levels between MIMU sensor‐based sprint mechanics variables and force plate recordings were obtained (mean±SD, force plate vs MIMU; V0, 8.61±0.85 vs 8.42±0.69; F0, 383±110 vs 391±103; P0, 873±246 vs 799±241; Sfv, −44.6±12.7 vs −46.2±10.7), ranging from 0.88 to 0.94, except for Drf, which showed weak‐to‐moderate correlation level (r=.45; −6.32±1.08 vs −5.76±0.68). Step‐averaged force values measured with both systems were highly correlated (r=.88), with a regression slope close to the identity (1.01). Bland and Altman graphical representation showed a no random distribution of measured force values. Finally, very large‐to‐extremely large retest correlation coefficients were found for the intertrial reliability of MIMU measurements of sprint performance variables (r value ranging from .72 to .96). Therefore, MIMUs showed appropriate validity and reliability values for 20‐m sprint performance variables.Publication Open Access Jumping biomechanics and function evaluation among both elite handball and recreational athletes recovering from acute anterior cruciate ligament reconstruction. An inertial sensor unit based study(2015) Setuain Chourraut, Igor; Izquierdo Redín, Mikel; Alfaro Adrián, Jesús; Ciencias de la Salud; Osasun ZientziakCon el objetivo de contribuir al conocimiento existente y ayudar en la problemática clínica con respecto a las limitaciones técnicas existentes actualmente en relación a la evaluación funcional así como el estímulo óptimo de rehabilitación a seguir tras la lesión del LCA, la presente Tesis Doctoral se plantea la evaluación en primera instancia de la capacidad de salto y posteriormente del patrón biomecánico del mismo sobre una cohorte de jugadores profesionales de balonmano con o sin reconstrucción previa de LCA. Así, se plantearon tres estudios transversales observacionales (estudios I, II, III) en los cuales se compararon el rendimiento en el salto (en términos de altura o distancia de salto alcanzada) y el patrón biomecánico del mismo (aceleraciones soportadas en los tres ejes del espacio así como las excursiones angulares descritas a nivel del tronco) entre los atletas con reconstrucción previa del LCA, y aquellos que no presentaban dicho antecedente. Para ello, se utilizó una batería de saltos verticales previamente validados, incluyendo maniobras verticales y horizontales como el Drop vertical bilateral y unilateral, el salto contra-movimiento así como dos maniobras de salto horizontal. Los resultados arrojados por este estudio, determinaron que en las jugadoras de balonmano con antecedente previo de lesión, demostraron alteraciones significativas (p< 0.05) en relación a la gestión de las aceleraciones soportadas a nivel del tronco, así como diferencias en la duración de las diferentes fases del salto, incluyendo la fase de vuelo en las maniobras de salto vertical unilaterales y bilaterales analizadas, a pesar de haber retomado el deporte de alta competición y llevar varias temporadas en el mismo. Sin embargo, al realizar el mismo análisis en los jugadores masculinos, no se encontraron diferencias significativas en el patrón biomecánico del salto, ni tampoco en el rendimiento demostrado en ellos en términos de duración de la fase del tiempo de vuelo.Publication Open Access Horizontal jumping biomechanics among elite female handball players with and without anterior cruciate ligament reconstruction: an ISU based study(BioMed Central, 2019) Setuain Chourraut, Igor; Bikandi Latxaga, Eder; Amu Ruiz, Francisco Antonio; Urtasun Arricaberri, Fernando; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun ZientziakBackground: Handball is a strenuous body-contact team sport that places high loads on the knee joint. Anterior cruciate ligament (ACL) tear is one of the most devastating injuries that any handball player can suffer, and female athletes are at particular risk due to their intrinsic anatomical, hormonal, neuromuscular and biomechanical characteristics. The purpose of this study was to analyze the horizontal jumping biomechanics of female elite handball players with or without previous ACL reconstruction. Methods: Twenty-one female participants (6 with previous ACL reconstruction and 15 uninjured controls) were recruited. Two horizontal hopping tasks were evaluated using inertial sensor unit (ISU)-based technology to assess jumping biomechanics through a direct mechanics-based approach. Results: The athletes with previous ACL reconstruction demonstrated a significant (P < 0.05) reduction in the unilateral triple hop for distance compared with the healthy controls. Furthermore, during the initial propulsive phase of the unilateral cross-over hop, the control participants generated significantly (P < 0.05) higher force values in the mediolateral direction (the X axis) with their dominant limb compared with the ACL-reconstructed (ACL-R) limb of previously injured participants. Conclusions: Three-dimensional horizontal jumping biomechanics analyses using ISU-based technologies could provide clinicians with more accurate information regarding the horizontal jumping biomechanical patterns among elite handball female athletes. Furthermore, several mechanical alterations could still be observed among those players who had undergone previous ACL reconstruction, even when several years have passed since the original ACL injury.
