Élaboration et validation d’un nouveau dispositif de surveillance des pressions plantaires : application à la décharge du pied
RESULTS: The asymmetrical profile of the human normal stance phase was validated. Under the heel, the pressure peaks lower by 28 %were noticed beneath the loading foot compared to the propulsive foot. Inversely, under the metatarsal heads and the hallux, the pressure peaks were greater by 32 %beneath the propulsive foot. For the two hemiplegic children, the plantar pressure profile equally highlighted significant differences between the unaffected and affected feet. The pressure peaks under the affected heel were respectively lower by 21 %and 97 %for H1 and H2. The loading function was found and associated to the affected limb. The propulsive function was not systematically found under the unaffected foot.
DISCUSSION: The analysis of plantar pressure measurements during able-bodied gait showed differences between the two lower limbs. These dynamic asymmetries are the results of a natural functional organization of the supports differentiating a loading foot and a propulsive foot and corroborating the concept proposed by Viel. The hemiplegic gait also presented dynamic asymmetries partially agreement with a personalized functional logic of loading and propulsion. However, the asymmetrical profile can also result a gait self-optimization strategy compensating biomechanical, anatomical and physiological disorders linked to the cerebral deficiency.

Analyse de la marche dans la maladie de Parkinson par enregistrement baropodométrique à l’aide de semelles embarquées Revue Neurologique, Volume 162, Issue 2, February 2006, Pages 208-213 D. Pihet, P. Moretto, L. Defebvre, A. Thevenon Abstract RésuméIntroductionDe nombreux travaux ont déjà été rapportés sur l’analyse de la marche dans la maladie de Parkinson à différents stades de la maladie ou pour évaluer l’effet de divers traitements. Quelques études ont été consacrées plus spécifiquement à la distribution des pressions plantaires lors de la marche. L’objet de ce travail est de valider l’intérêt des mesures baropodométriques dans l’étude de la marche de sujets parkinsoniens en périodes On et Off à différents stades de sévérité. |
