Neck injury to avoid with neck brace motocross

The development of MOVEO Safety products is based in the given relationship between human behaviour on extreme conditions, and the kinematic and dynamic parameters that can be measured nowadays on impact testing.

This relationship, in constant evolution, is the base of biomechanics, science looking for quantification of body injuries by means of objective parameters and criteria, obtained by comparison with testing on dead bodies, animals, volunteers, recorded with highly instrumented anthropomorphic dummies.

Not to exceed the biomechanic threshold of the human resistance is the mainstay of the development of our products, which let us evaluate and confirm the level of protection provided by our products. First example is the MOVEO Neck BRACE

 
Compression injury to minimize with neck brace motocross Neck injuries by compression.

Main characteristic for injuries this kind is the displacement and/or fracture of the cervical vertebrae, even his blast, caused mainly by direct impact over the helmet.

Main biomechanical criterion to evaluate this mechanism is the compression force Fz, recorded with the load cell allocated in the upper side of the dummie's neck.

Hyperextension mechanism to reduce with neck brace motocross Neck injuries by hiperextension.

Main characteristics for injuries this kind are the tear and breakdown of the front ligaments, fracture of the vertebrae positioned in the rear side, displacement of the upper vertebrae, and flattening of intervertebral discs.

Main biomechanical criterion to evaluate this mechanism is the moment My negative (head tilting backward), recorded with the load cell allocated in the dummie's neck.

 
Hyperflexion mechanism to reduce with neck brace motocross Neck injuries by hiperflexion.

Main characteristics for injuries this kind are the tear and breakdown of the rear ligaments, displacement of the vertebrae mainly in the upper side, and fracture of vertebrae in the frontal side.

Main biomechanical criterion to evaluate this mechanism is the moment My positive (head tilting forward), recorded with the load cell allocated in the upper side of the dummie's neck.

Lateral Hyperflexion mechanism to decrease with neck brace Neck injuries by lateral hiperflexion.

Main characteristics for injuries this kind are overstretching of the nerves alongside the cervical vertebrae, and the fracture of vertebrae in his side.

Main biomechanical criterion to evaluate this mechanism is the lateral moment Mx, recorded with the load cell allocated in the upper side of the dummie's neck.

 
Shear mechanism to minimize with the neck brace motocross Neck injuries by shearing.

Main characteristics for injuries this kind are the breakdown of vertebrae in the upper neck and breakdown of ligaments, caused mainly by direct impact over the helmet.

Main biomechanical criterion to evaluate this mechanism is the front-post shearing force Fx, recorded with the load cell allocated in the upper side of the dummie's neck.

Whiplash control with neck brace motocross Neck injuries by whiplash.

Main characteristic for injuries this kind are is pain in the neck caused by moderate shearing forces followed by tension-extension of the neck, causing injuries in tendons and ligaments, which are caused mainly by hit impact.

Main biomechanical criteria to evaluate this mechanism are those recorded with the BioRID II dummy, Nij and Nkm when referred to upper neck, or LNL if referred to the lower neck.
