Résumé

La possibilité d’estimer la mécanique lombaire in-vivo a été évaluée par imagerie ultrasonique. Les images ont été obtenues, alors que le patient était assis, le bassin fixé, et étiré au moyen d’un câble, contractant iso-métriquement les muscles du tronc à différents niveaux de force. Une régression linéaire a été utilisée pour identifier les mesures d’ultrasons corrélées avec la force du tronc. Les résultats suggèrent que les ultrasons sont mieux adaptés à l’estimation de la mécanique lombaire durant une flexion latérale que pendant une extension du tronc. Une relation linéaire a été trouvée entre les changements d’épaisseur de certains muscles et la force du tronc, ce qui pourrait fournir une alternative aux électrodes intramusculaires invasives utilisées pour mesurer l’activité des muscles non-superficiels. Cependant, l’amplitude des changements, fréquemment très proche de la résolution ultrasonique, représente une limitation significative.
