Relationship between low back pain and shortened hamstring muscles: a case-control study

[Resumen] Objetivos: Este estudio busca establecer una relación directa entre el dolor lumbar de origen inespecífico y el acortamiento de la musculatura isquiotibial mediante la prueba dedos suelo (Finger-to-floor). Material y métodos: En el presente estudio participaron 54 sujetos: 27 casos y 27 controles (41 mujeres y 13 hombres). Resultados: No se ha encontrado relación entre los casos y los controles en las variables Finger-To-Floor test 1 (FTF1) (rP= 0.079; P>0.570), Finger-To-Floor test 2 (FTF2) (rP= 0.000; p>0.998), Finger-To-Floor test 3 (FTF3) (rP= 0.075; p>0.588) y Finger-To-Floor test total (FTFtotal) (-0.006 (-5.23,5.11);p>0.981). Conclusión: No se encontraron diferencias estadísticamente significativas entre ambos grupos y las respectivas variables.[Abstract] Objectives: This study tries to establish a direct relationship between non specific low-back pain and shortened hamstrings by using fingerto- floor test (FTF). Methods: A sample of 54 subjects divided into 27 cases and 27 controls (41 female and 13 male) was recruited. Results: Regarding outcome measurements, a statically significant relationship between the cases and the control was not found: Finger- To-Floor test 1 (FTF1) (rP= 0.079; P>0.570), Finger-To-Floor test 2 (FTF2) (rP= 0.000; p>0.998), Finger-To-Floor test 3 (FTF3) (rP= 0.075; p>0.588) and Finger-To-Floor test total (FTFtotal) (-0.006 (-5.23,5.11); p>0.981). Conclusion: No statistically significant differences were found between both groups for outcome measuraments
