Study of the Effect of Botulinum Toxin Injection in Rectus Femoris and Triceps on the Length and the Strength During Locomotion in Chronic Hemiparetic Patients (FOLOTOX)
Double Blind Randomized Controlled Study of the Effect of Botulinum Toxin Injection in Rectus Femoris and Triceps on the Length and the Strength of These Muscles During Locomotion in Chronic Hemiparetic Patients
The aim of this randomized controlled study is to quantify the modification during locomotion of chronic hemiparetic patients of the strength and the length of Rectus Femoris and Triceps Surae induced by botulinum toxin injection type A.
The main hypotheses of this study based on previous studies are that botulinum toxin injection increases on one hand the length of the muscle injected during gait and on the other hand decreased the strength of the muscles injected.
The investigators also hypothesized that botulinum toxin injection improved the strength of the antagonist muscles and normalized the pattern of strength of the muscles injected during gait.

Detailed Description
The aim of this study is to compare versus placebo the effects of BTX-A injection on :
- the maximal length of the muscles injected during gait
- the maximal lengthening velocity of the muscles injected during gait
- the maximal strength of muscles injected during gait
- the inter-limb coordination assessed by continuous relative phase
- the kinematic parameters such as peak knee flexion during swing phase of the gait cycle and peak ankle dorsiflexion during stance phase.
To that end each patient included in the study will be assessed before injection, one month after the BTX-A injection and 3 months after BTX-A injections.
All patients will underwent a clinical examination, a 3D gait analysis and a isokinetic dynamometer analysis.
The comparison of the results in the group treated by BTX-A will permit to show that one month after BTX-A injection peak length during gait of muscles injected, maximal lengthening velocity peak knee flexion during swing phase and peak ankle dorsiflexion increase significantly.
It will also permit to show that the maximal strength of muscles injected decreases whereas the strength of antagonist increases It will also permit to demonstrate that multisite BTX-A injection improve coordination of paretic and non paretic lower limb the inter-group comparison will permit to demonstrate that these modification are mainly due to multisite BTX-A injections.
