Assessment of the Effects of Early Proprioceptive Stimulations in Patients With Severe Traumatic Brain Injury

Assessment of the Effects of Early Proprioceptive Stimulations in Patients With Severe Traumatic Brain Injury : a Randomized Controlled Trial

"Severe traumatic brain injury (TBI) is a serious condition, common in young adults. It leads to sensorimotor and cognitive sequelae that hinder social reintegration. Neuronal plasticity must be used quickly before natural recovery impedes neuronal regrowth. In this respect, stopping sedation as soon as possible and early mobilization, even if the patients are unconscious, are recognized as useful measures to promote recovery. However, at the early stage, the environment of the ICU and the acute condition of the patients limit the rehabilitation possibilities. In such a context, functional proprioceptive stimulations (Vibramoov™ system, Techno Concept, France) could be a tool of interest.

By using the proprioceptive signatures of cyclic movements, proprioceptive stimulations can elicit the illusion of these movements. A motor response can even be obtained through the interactions between the peripheral nervous system and the central nervous system. Finally, such stimulations facilitate the initiation of the mimicked movements. Some studies have already shown the benefits of proprioceptive vibrations. However, so far, these benefits have only been studied at the chronic stage of neurological diseases. The investigators hypothesized that early functional proprioceptive stimulations (FPS) may reduce spasticity and promote recovery in patients with severe traumatic brain injury.

To test the hypothesis, the investigators conduct a randomized controlled trial on patients with severe traumatic brain injury. Every patient will be included as soon as possible in the ICU and receive either FPS, either sham stimulations to the joints of the lower limbs, 4 times a week during 8 weeks. The primary outcome measures will assess spasticity. The investigators also assess pain, coma recovery; muscle wasting and cognitive impairments. "
