Pediatric Dynamic Elastomers
Bounders are a patent pending elastomer technology that store and return energy—mimicking normal muscle function—to produce both eccentric and concentric contractions and, if needed, a ground reaction force.
Bounders are an easy-to-use expandable dynamic bracing system to treat pediatric and young adult patients and feature standardized sizes and three levels of performance,

HOW BOUNDERS WORK:
In midstance, the tibia progress forward over the foot as the ankle begins to move into dorsi-flexion. At this point, Bounders elongate similar to the posterior compartment muscles, and the eccentric action pulling on the elastomer assists the tibial progression and provides a smooth transition from the loading response. The elongation of the Bounders elastic structure stores potential energy which is used later and released in the gait cycle for active

Bounders Knowledge Base
Bounders are perfect for:
Crouch gait |
Weak or absent forefoot push off |
Insufficient anterior control of tibia |
Low tone with poor proprioception |
Spastic Diplegia |
Spasticity |
Developmental delays |
Bounders deliver results:
Limits tibial progression to produce a ground reaction |
Produces active plantar-flexion |
Eccentric control to assist with smooth progression of the tibia |
Controlled kinesthetic awareness |
Works with patient's muscles to provide support for normal gait |
Reduces the effects of Dystonia through increased proprioception |
Tone reducing |
