摘要
MATERIAL AND METHOD: Thirty healthy control subjects and two hemiplegic children (H1 and H2) performed a walking test at self selected speed. The recordings of dynamic parameters were realized thanks to an in-shoe plantar pressure analysis system (Parotec, by Paromed Medizintechnik, GMBH, Germany). The pressure peaks were determined from the recording of pressures under eight footprint locations. A program calculated the sum of forces under the heel and determined the loading foot. By defect, the second foot is the propulsive foot.

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.
