Brief summary
Ankle rehabilitation training becomes a tough question for the patients with ankle joint injuries especially with the hemiplegia after stroke. Here a novel powered ankle foot orthoses which can provide ankle dorsiflexion and plantar flexion assistant using electric motor is proposed in this paper. The mechanical structure of the orthoses includes wearing parts, ankle joint hinged part, driving unit, transmission mechanism and sensing units. This study provides a new method for ankle foot orthoses design and has great significance for ankle rehabilitation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| good performance of the ankle foot orthosis | one month | Two researchers wore the ankle foot orthosis without any motion to test the rationality of design size and wearing coordination；motion experiment without load was carried out to test the stability of transmission structure and effectiveness of motor control. The ankle foot orthosis was fixed on a table. |
