Mitchell Quick Release Spring Assist Dobbs Bar
A spring reset brings the child's feet back to neutral in a resting position. The spring maintains an active dorsiflexion stretch while still allowing the child to play and crawl in the brace.
Available in sizes Small and Regular.
The following information is from the manufacturer's website: http://www.dobbsbrace.com/faq (additional emphasis added). Please contact D-Bar Enterprises at 314-968-8555 if you have any questions or concerns about the Dobbs Bar.
The Small bar adjusts from 6 to 9 inches (15.25 cm to 22.86 cm) and the Regular bar adjusts form 9 to 14 inches (22.86 cm to 35.56 cm). The Dobbs bar should be set so that the width of the bar is equal to the shoulder width of the child. Due to the difference in spring tension between a small and regular size bar, we recommend that children under 12 months of age be in a small size bar with the lighter spring tension and children over 12 months use the regular size bar with the heavier spring tension. WARNING: A regular size bar should not be placed on a child under the age of 12 months. The spring tension in a regular size bar is much heavier than in a small size bar and could overpower the child's feet causing pressure on the skin.
While the Dobbs Bars do allow for great freedom and better compliance, the motion is an up and down pedaling motion (not a forward stepping motion); as such, they are not intended for walking. The Dobbs bars are used mostly as a nighttime brace that allows your child to kick and move his/her legs independently and get more comfortable than in any fixed foot abduction bar.
