Correlación entre el control postural y neuromuscular con cuestionarios de percepción funcional en deportistas con inestabilidad de tobillo

Abstract

ObjectiveTo determine the correlation between postural and neuromuscular control assessments and questionnaires of subjective perception in athletes with functional ankle instability. Material and methodsA descriptive study with a correlational design was performed. Ten male athletes participated. Postural control was measured from the displacement of the center of pressure (COP) in the medio-lateral (ML) and anteroposterior (AP) directions. The following variables were obtained: area, ML variability, AP variability, ML velocity and AP velocity. Bipodal and unipodal measurements with opened eyes (OE) and closed eyes (CE) were made. Muscle reaction time of peroneus longus (PL), peroneus brevis (PB) and tibialis anterior (TA) was recorded with surface electromyography in sudden ankle inversion test. Functional ankle perception questionnaires were administered: AJFAT and CAIS. The statistical analysis was performed with the Pearson Test. Significance level was established a priori at P<0.05. ResultsThere was a moderate negative correlation between AJFAT with PL muscle (r=-0.64, P=0.049) and with the CAIS and PL muscle (r=-0.65, P=0.044). Strong negative correlations were observed between the AJFAT questionnaire and COP area in unipodal EC (r=-0.75, P=0.013) and between the CAIS questionnaire and COP velocity ML in and unipodal EC (r=-072, P=0.019). ConclusionsThe use of questionnaires applied in this study could be useful in assessing the functional limitations of patients with functional ankle instability, favoring the physiotherapy approach to these patients.
