简要总结
Approximately 20% of stroke survivors have difficulties to dorsiflex the ankle and clear the ground during walking. This impairment, termed as "foot drop", is caused by an association of weak dorsiflexors and increased spasticity and stiffness of the plantar-flexors. As a consequence, walking performances are reduced and energy cost of walking is deteriorated. This may increase performance fatigability, as the locomotion will be realized at a higher percentage of the subjects' capacities. In order to overcome these issues, different treatments are proposed. One of the most conventional solutions are the use of ankle foot orthosis (AFO) and it is the most commonly prescribed device used to compensate for "foot drop". There is a very large choice of AFO on the market which can be proposed to patients with foot drop.
The aim of this study is thus to assess the mechanical effects of using a manufactured carbon AFO in by comparison to a custom-made thermo-plastic AFO on walking capacity (distance and energy cost), fatigue and "foot drop" control throughout the gait phase in patients with hemiparetic stroke.

研究组 & 干预措施
Carbon-AFO (C-AFO)
Manufactured carbon ankle foot orthosis (C-AFO) Sprystep (Thuasne) will be provided to patients. A familiarization with C-AFO will be performed before doing the tests.
干预措施: Ankle Foot orthosis (AFO) (Device)
Custom-made thermo-plastic orthosis (CM-AFO)
Own custom-made thermo-plastic orthosis (CM-AFO) of patients. A familiarization will be performed also before doing the tests.
干预措施: Ankle Foot orthosis (AFO) (Device)
Without orthosis (NO)
No orthosis - patient will wear only their shoes
结局指标
主要结局
Distance walked during the 6 Minute Walk Test (6MWT)
时间窗: Day : 14
Patient will performed three experimental session (14 days between each session) during wich the primary outcome will be assessed : one session while walking with C-AFO, one session while walking with CM-AFO, and one session while walking without AFO (randomized order). 6 Minute Walk Test is a beneficial tool to evaluate walking endurance in patients with poststroke hemiparesis
