Este estudio ha sido identificado como potencialmente de alto impacto.
La métrica de alto impacto de OE, impulsada por la IA, estima la influencia que probablemente tendrá un artículo integrando señales tanto de la revista en la que se publica como del contenido científico del propio artículo.
Desarrollado mediante el procesamiento del lenguaje natural más avanzado, el modelo de Alto Impacto de OE predice con mayor precisión el futuro rendimiento de las citas de un estudio que el factor de impacto de la revista por sí solo.
Esto permite reconocer antes las investigaciones clínicamente significativas y ayuda a los lectores a centrarse en los artículos con más probabilidades de configurar la práctica futura.
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(11):299 American Journal of Sports Medicine; 2011; 39(11): 2296-230350 Danish male professional and amateur soccer teams (n=942) were cluster randomized to receive either eccentric strengthening of the hamstring muscle using the Nordic hamstring muscle exercise (intervention) or the usual training program (control). The results after the 10-week program concluded that the control groups had significantly higher rates of acute hamstring injury in comparison to intervention. In addition, the control group had a significantly higher proportion of recurrent injury rates in comparison to intervention.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

El Índice de Fragilidad es una herramienta que ayuda en la interpretación de hallazgos significativos, proporcionando una medida de fuerza para un resultado. El Índice de Fragilidad representa el número de eventos consecutivos que es necesario añadir a un resultado dicotómico para que el hallazgo deje de ser significativo. Un número pequeño representa un hallazgo más débil y un número grande un hallazgo más fuerte.
¿Por qué se necesitaba ahora este estudio?
Hamstring injury accounts for 12% to 16% of all soccer related injuries, making it the most prevalent injury. Eccentric hamstring strength training exercises have undergone a series of developments with an advantage of capability to be done in the field without the use of any equipment. The effect of eccentric hamstring strength training on hamstring injuries have been incongruous in the literature, and this study explores it further.
¿Cuál era la pregunta principal de la investigación?
Does eccentric strengthening of the hamstring muscle lead to lower rates of overall, new, and recurrent acute hamstring injuries after a 10 week sessions, in comparison to control in athletes of professional and amateur soccer teams?
- Overall acute hamstring injury rates were 3.8 per 100 player seasons in the intervention group in comparison to 13.1 per 100 player seasons in control (adjusted rate ratio= 0.293; 95% confidence interval, 0.150-0.572; P<0.001)
- New injury rates were 3.1 per 100 player seasons in the intervention group in comparison to 8.1 per 100 player seasons in the control (RR, 0.410; 95% CI, 0.180-0.933; P=0.034)
- Recurrent injury rates were 7.1 per 100 player seasons in the intervention group in comparison to 45.8 per 100 player seasons in the control (RR, 0.137; 95% CI, 0.037-0.509; P=0.003)
¿Qué es lo que más debo recordar?
The results indicate that eccentric training was effective in significantly decreasing the rate of acute hamstring injuries in soccer athletes.
¿Cómo afectará esto al cuidado de mis pacientes?
Based on the findings of this study, therapists should consider eccentric training to be a potentially viable exercise option.
