Condition: Botulinum Toxin Injection · Stiff Knee Gait · Fall Risk · Sponsor: Hopital Nord Franche-Comte
Patients who suffered a stroke, cranial traumatism, medullar lesions or multiple sclerosis can present spastic muscular complications, which is particularly impairing if it concerns muscles of the leg. Muscular spastic complications of the legs can alter significantly the ability to walk because it clinically manifests itself by a stiffness of the leg, thus generating a complication called "Stif Knee Gait" (SKG). It means that the femoro-patello-tibial articulation cannot be mobilized as it should because it stays spastic instead of being mobile. However, it remains possible to treat this kind of medical condition by using Botulinum toxin injections in the target muscle, in particular the rectus femoris (which is part of the quadriceps). As a reminder, botulinum toxin, sold under the international common denomination "Botox®", is a neurotoxin of 150 kDa produced by the bacteria "Clostridium Botulinum" and is the most powerful natural poison known to humankind, with its DL50 between 1 and 2 nanogramms / kg in humans. This toxin works by entering the neuro-muscular synaptic junctions and by linking itself to a proteic complex called SNARE. The link between the toxin and the SNARE complex inhibits the fusion of the acetylcholinergic synaptic vesicles with the plasmic membrane of the pre-synaptic axone. The Botox® blocks the exocytosis of the acetycholin (Ach) vesicle in the inter-synaptic space at the neuro-muscular junction and blocks the nervous transmission, thus generating…
