Brief Summary:

Chronic stroke patients exhibit gait pattern alterations which are mainly due to spasticity and treated with repetitive multifocal botulinum toxin injection(BTI). Several studies demonstrated that single BTI-session in a single muscle of paretic lower limb(LL) improved kinematic gait parameters(GP) but surprisingly none of them assessed the effects of repetitive multifocal BTI on patient's gait pattern and their duration.

The aim was to evaluate the impact of repetitive multifocal BTI-sessions on GP of chronic stroke patients. To that end, gait of patients has been compared using 3D-gait analysis after at least 2 consecutive BTI sessions.

Condition or disease Intervention/treatment
Effect of Repeated Botulinum Toxin Injection on Gait Pattern in Stroke Patients Other: Motion analysis

Detailed Description:
All the patients will be tretaed with BTI . these injections will be performed under electrical stimulation control (~5mA). The dose, the number of site of injection per muscle is at the discretion of the physician according to patients' needs and physicians' routine clinical practice. The dilution the most commonly used will depend on the type of BoNT-A (BOTOX®, XEOMIN® or DYSPORT®) and was 100 U for 2.5ml (BOTOX® and XEOMIN®) or 500 U for 2.5 ml (Dysport®).

Group/Cohort Intervention/treatment
Chronic spastic stroke patients
Chronic spastic stroke patients treated regularly with botulinum toxin injection in lower limb muscles
Other: Motion analysis
Motion analysis was used to assess the modifications of gait pattern in chronic spastic stroke patients regularly treated with botulinum toxin injection

Primary Outcome Measures :
  1. kinematics gait parameters [ Time Frame: 3h ]
    peak knee flexion in swing phase(°)

Secondary Outcome Measures :
  1. spatiotemporal gait parmeters [ Time Frame: 3h ]
    gait velocity(m/s)
