简要总结
This pilot study will aim to understand the potential benefit of the assessment of walking using video slow motion for muscle selection and the development of an image catalogue guide of the potential results of injection of abobotulinumtoxinA by comparing foot postures before and after injection. The objective is to evaluate the use of video assessment to improve muscle selection for the injection of botulinum toxin A to improve walking outcomes. Primary outcomes include: self-selected velocity (SSV), maximal velocity (MV) and symmetry of walking. Secondary outcomes include: passive range of motion (PROM), Modified Ashworth Scale (MAS) and the Tardieu Scale (TS). Fifteen persons post stroke or TBI over age 18 with equinovarus foot deformity who are able to ambulate will be included in the study. Dysport 1000 to 1500 units will be used to be distributed on the basis of clinical indication to ankle plantar flexors (gastrocnemius and soleus), tibialis posterior and long toe flexors. The duration of subjects' participation is 4-6 weeks.
详细描述
This is a prospective, single arm, non-randomized clinical study with pre-post assessment to include post-stroke and Traumatic Brain Injury (TBI) outpatients with spastic ankle / foot muscles amenable to botulinum toxin injection. Subjects must be able to walk without braces.
AbobotulinumtoxinA injection in a dose range of 500 to 1500 units one time to be distributed on the basis of clinical indication to ankle plantar flexors (gastrocnemius and soleus), knee extensors, knee flexors, tibialis posterior and long toe flexors.

研究组 & 干预措施
Dysport
Subjects will receive 1000 to 1500 units of Dysport to be distributed on the basis of clinical indication to ankle plantar flexors (gastrocnemius and soleus), knee extensors and flexors, tibialis posterior and long toe flexors for one injection.
干预措施: Dysport (Drug)
结局指标
主要结局
Self-Selected Velocity (SSV)
时间窗: Baseline, Follow-up (4-6 weeks)
Baseline and follow-up SSV with and without shoes. Distance covers over time at self selected pace. Larger value is better.
Maximal Velocity
时间窗: Baseline, Follow-up (4-6 weeks)
Baseline and follow-up MV with and without shoes. Distance covers over time when walking as fast as possible. Larger value is better.
Step-length at Baseline and at Follow-up (Temporal-spatial Data)
时间窗: Baseline, Follow-up (4-6 weeks)
Step length measured as the distance between the heel contact point of one foot and that of the other foot. Values are reported on the involved side. Larger values represent better outcome.
次要结局
- Modified Ashworth Scale (MAS) at Baseline and at Follow-up(Baseline, Follow-up (4-6 weeks))
- Tardieu Scale (TS) at Baseline and at Follow-up(Baseline, Follow-up (4-6 weeks))
- Passive Range of Motion (PROM) at Baseline and at Follow-up(Baseline, Follow-up (4-6 weeks))
