Valoración del equilibrio postural en bipedestación-sedestación en sujetos sanos mediante acelerometría. Estudio piloto

Abstract

IntroductionAssessment of postural control and balance is very important to guide therapeutic interventions, these being the most affected aspects that limit people with alterations in gait, posture, and activities of daily life. It has been shown that the accelerometry is useful for assessment of postural balance. ObjectivesTo determine efficient indicators based on accelerometry to assess sitting and standing in stability and instability situations, with and without visual control in a preliminary study in healthy subjects. MethodologyTwenty-six healthy subjects were evaluated by placing triaxal accelerometers and performing different tests in sitting and standing positions. ResultsThe energy required to find a balance in instability situations was seen in a frequency band of 1.5-3Hz. ConclusionsThe indicators that could be useful for the therapists to assess postural control and balance are: root mean square, energy spectral density and frequency spectrum.
