Objetivo: Establecer un modelo predictivo de riesgo de lesión en base a descriptores anatómicos y funcionales con la inestabilidad articular en rodilla y tobillo en jugadores de baloncesto no profesionales. Diseño y participantes: Estudio no experimental, descriptivo de corte transversal, muestreo dirigido; fueron evaluados 44 sujetos universitarios de ambos sexos, 27 hombres (61,4%) y 17 mujeres (38,6%); basquetbolistas no profesionales de edad entre 18 – 26 años (22 ± 3,2), pertenecientes a la rama deportiva de basquetbol universitario de Chile. Resultados: - (p= .000) Rodilla estrés en valgo establece asociación significativa con ángulo postural en rodilla y tobillo y variables funcionales de despegue, nivel de discriminación basado modelo 82% (CC= .820). - (p= .000) Tobillo estrés valgo establece asociación significativa con el ángulo de rodilla y tobillo, variables funcionales de despegue, nivel de discriminación basado modelo 71,3% (CC= .713). - (p= .000) Riesgo general establece asociación significativa con el ángulo rodilla, variables funcionales despegue y aterrizaje, estrategia tobillo. nivel de discriminación del modelo 83,5% (CC= .835). Conclusión: Existen factores posturales, funcionales de despegue y de aterrizaje que se asocian significativamente con el riesgo de lesión de inestabilidad articular en jugadores de baloncesto no profesionales. Abstract. Objective: To establish a predictive model of injury risk based on anatomical and functional descriptors with knee and ankle joint instability in non-professional basketball players. Design and participants: Non-experimental, descriptive cross-sectional study, directed sampling; 44 university subjects of both sexes, 27 men (61.4%) and 17 women (38.6%) were evaluated; non-professional basketball players aged between 18 - 26 years (22 ± 3.2), belonging to the sports branch of university basketball in Chile. Results: - (p = .000) Valgus knee stress establishes a significant association with postural angle in the knee and ankle and functional variables of take-off; level of discrimination based on model 82% (CC = .820). - (p = .000) Ankle valgus stress establishes a significant association with the knee and ankle angle, functional variables of take-off; level of discrimination based on model 71.3% (CC = .713). - (p = .000) General risk establishes a significant association with the knee angle, take-off and landing functional variables; ankle strategy; level of discrimination of the model 83.5% (CC = .835). Conclusion: There are postural, functional take-off, and landing factors that are significantly associated with injury risk of joint instability in non-professional basketball players.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
