Readers can expect to gain a comprehensive understanding of the design, function, and benefits of different ankle orthoses. We will delve into the clinical considerations for selecting the appropriate device, as well as the impact of cultural factors on orthotic use in China. Additionally, the guide will highlight case studies and expert insights to provide practical knowledge for healthcare professionals and patients alike.

Ankle Orthoses: A Comprehensive Guide

The ankle joint is one of the important joints of the human body to maintain the ability to walk. Diseases such as stroke and ankle osteoarthritis could weaken the body’s ability to control joints, causing people’s gait to be out of balance. Ankle-foot orthoses can assist users with neuro/muscular or ankle injuries to restore their natural gait. Currently, passive ankle-foot orthoses are mostly designed to fix the ankle joint and provide support for walking. With the development of materials, sensing, and control science, semi-active orthoses that release mechanical energy to assist walking when needed and can store the energy generated by body movement in elastic units, as well as active ankle-foot orthoses that use external energy to transmit enhanced torque to the ankle, have received increasing attention. This article reviews the development process of ankle-foot orthoses and proposes that the integration of new ankle-foot orthoses with rehabilitation technologies such as monitoring or myoelectric stimulation will play an important role in reducing the walking energy consumption of patients in the study of human-in-the-loop models and promoting neuro/muscular rehabilitation.

Types of Ankle Orthoses

Ankle orthoses can be categorized into several types based on their design and functionality. The following table summarizes the different types of ankle orthoses available in the market.

Type	Description	Example Domains
Static AFO	Provides fixed support to the ankle joint.	www.wonderful-po.com
Dynamic AFO	Allows for some movement while providing support.	www.nobel.hk
Hinged AFO	Features hinges for controlled movement.	www.huakangortho.com
Carbon Fiber AFO	Lightweight and strong, ideal for active users.	www.wonderful-po.com
Custom AFO	Tailored to individual needs and specifications.	pubmed.ncbi.nlm.nih.gov

Static AFO

Static AFOs are designed to immobilize the ankle joint, providing maximum support. They are often used for patients with severe weakness or instability. These orthoses are typically made from rigid materials and are less flexible.

Dynamic AFO

Dynamic AFOs allow for controlled movement while still providing support. They are beneficial for patients who need assistance with gait but still have some muscle control. These orthoses often incorporate materials that allow for flexibility.

Hinged AFO

Hinged AFOs feature mechanical hinges that enable controlled movement of the ankle joint. This design allows for a more natural gait pattern, making them suitable for active rehabilitation.

Carbon Fiber AFO

Carbon fiber AFOs are known for their lightweight and durable properties. They are ideal for active users who require support without the added weight of traditional materials.

Custom AFO

Custom AFOs are tailored to meet the specific needs of individual patients. They can be designed to accommodate unique anatomical features and functional requirements.

Conclusion

Ankle-foot orthoses play a crucial role in rehabilitation and support for individuals with ankle injuries or conditions affecting their gait. With advancements in technology and materials, these devices have evolved to provide better support, flexibility, and comfort. Whether through passive, semi-active, or active designs, ankle orthoses can significantly enhance mobility and quality of life for users. Companies like www.wonderful-po.com, www.nobel.hk, and www.huakangortho.com are at the forefront of developing innovative solutions in this field.
