Appareil de marche Rotorod Le rotorod était un cylindre rotatif, 4 cm de diamètre, 35 cm fixée au-dessus du sol et fermé par plexiglas transparent. Le cylindre a été rotorod recouverts d&#39;un revêtement en caoutchouc texturé, ce qui facilite la traction. Le plancher de l&#39;appareil était couvert d&#39;une couche de mousse pour éviter les blessures lorsque les animaux ont diminué.

Revised Abstract:
High speed videoanalysis of the details of movement can provide a source of information about qualitative aspects of walking movements. When walking on a rotorod, animals remain in approximately the same place making repetitive movements of stepping. Thus the task provides a rich source of information on the details of foot stepping movements. Subjects were hemi-Parkinson analogue rats, produced by injection of 6-hydroxydopamine (6-OHDA) into the right nigrostriatal bundle to deplete nigrostriatal dopamine (DA). The present report provides a video analysis illustration of animals previously were filmed from frontal, lateral, and posterior views as they walked (15). Rating scales and frame-by-frame replay of the video records of stepping behavior indicated that the hemi-Parkinson rats were chronically impaired in posture and limb use contralateral to the DA-depletion. The contralateral limbs participated less in initiating and sustaining propulsion than the ipsilateral limbs. These deficits secondary to unilateral DA-depletion show that the rotorod provides a use task for the analysis of stepping movements.
Additional Discussion Paragraph:
A more detailed presentation of the present study has been made (Whishaw et al, 2003), but the present study presents the video support describing the stepping movement in the good and affected limbs of unilateral dopamine-depleted rats. For the analysis, rats with unilateral DA depletions and control rats were video recorded from front, lateral and posterior views. A rating scale of posture and forelimb movements indicated that stepping movements were chronically impaired following surgery. Examination of limb movements indicated that whereas the DA-depleted rats could use the limbs contralateral to the lesion for support, they received minimal use for shifting weight. The results of this study indicate that the rotorod task, in addition to providing quantitative measures of motor impairments, can also provide insights into the qualitative impairments.
Original Abstract:
The rotorod test, in which animals walk on a rotating drum, is widely used to assess motor status in laboratory rodents. Performance is measured by the duration that an animal stays up on the drum as a function of drum speed. Here we report that the task provides a rich source of information about qualitative aspects of walking movements. Because movements are performed in a fixed location, they can readily be examined using high-speed video recording methods. The present study was undertaken to examine the potential of the rotorod to reveal qualitative changes in the walking movements of hemi-Parkinson analogue rats, produced by injection of 6-hydroxydopamine (6-OHDA) into the right nigrostriatal bundle to deplete nigrostriatal dopamine (DA). Beginning on the day following surgery and then periodically over the next two months, the rats were filmed from frontal, lateral, and posterior views as they walked on the rotorod. Behavior was analyzed by frame-by-frame replay of the video records. Rating scales of stepping behavior indicated that the hemi-Parkinson rats were chronically impaired in their posture and in the use of the limbs contralateral to the DA-depletion. The contralateral limbs not only displayed postural and movement abnormalities, they participated less in initiating and sustaining propulsion than did the ipsilateral limbs. These findings not only reveal new deficits secondary to unilateral DA-depletion, but also show that the rotorod can provide a robust tool for the qualitative analysis of movement.

Erratum: Use of Rotorod as a Method for the Qualitative Analysis of Walking in Rat

use of rotorod as a method for the qualitative analysis of walking in rat

Le test rotorod, dans laquelle les animaux marchent sur un tambour rotatif, est largement utilisé pour évaluer l&#39;état du moteur chez les rongeurs de laboratoire. La performance est mesurée par la durée que l&#39;animal reste en place sur le tambour en fonction de la vitesse du tambour. Nous rapportons ici que la tâche fournit une riche source d&#39;informations sur les aspects qualitatifs des mouvements de marche. Parce que les mouvements sont effectués dans un endroit fixe, elles peuvent facilement être examiné en utilisant des méthodes à haute vitesse d&#39;enregistrement vidéo. La présente étude visait à examiner le potentiel de la rotorod pour révéler des changements qualitatifs dans les mouvements de la marche des rats analogique hémi-Parkinson, produit par l&#39;injection de 6-hydroxydopamine (6-OHDA) dans le faisceau droit nigrostrié à épuiser la dopamine nigro (DA ). À compter du jour suivant la chirurgie, puis périodiquement au cours des deux prochains mois, les rats ont été filmées à partir des vues frontales, latérales et postérieures comme ils marchaient sur la rotorod. Comportement est analysé par image par image rediffusion des enregistrements vidéo. Les échelles d&#39;évaluation du comportement de l&#39;intensification indiqué que les rats hémi-Parkinson étaient chroniquement déficients dans leur posture et de l&#39;utilisation des membres controlatérale à l&#39;AD-épuisement. Les membres controlatéraux non seulement affiché des anomalies de posture et du mouvement, ils ont moins participé au lancement et au maintien de propulsion que ne les membres homolatéraux. Ces résultats ne révèlent pas seulement des nouveaux déficits secondaires à unilatérales DA-épuisement des ressources, mais aussi montrer que la rotorod peut fournir un outil robuste pour l&#39;analyse qualitative du mouvement.
