Problems solved by technology

However, it still has the disadvantage of having to be carefully assembled by a clinical technician
This means that it may take a considerable amount of time to manufacture and fit the orthosis, so the most immediate drawback is that the applicant's previously proposed device is still quite expensive

Embodiment Construction

[0032] Figure 6a is a perspective view of an embodiment of the present invention. The orthosis in Figure 6a shows what it would look like when worn by a patient (the patient's foot and ankle have been omitted for clarity). When not worn by the patient, the orthosis assumes an approximately two-dimensional shape for ease of storage.

[0033] As shown, the orthosis includes a generally sock-shaped elastic structure 50 . The sock comprises a first tubular portion 52, and a continuous second tubular portion 54, which in most cases is integrally formed with the first tubular portion.

[0034]The first and second tubular portions are arranged at an angle to each other so as to form, at least in use, a generally L-shaped inner cavity 56 sized to accommodate a patient's foot and ankle (not shown). and fit tightly around it.

[0035] Elastic flexible ribs 58 are provided on the structure and extend along the dorsum of the patient's foot from the proximal end 60 of the orthosis (whic...

Abstract

An embodiment of the invention provides an ankle-foot orthosis that comprises: an elastic structure (50) formed of contiguous first (52) and second (54) tubular members, said second tubular member being set at an angle to the first tubular member to define, at least in use, a generally L-shaped cavity (56) configured to accept and fit closely about the foot and ankle of a patient; and a rib (58) which is permanently bonded or otherwise permanently affixed to a region of the structure which overlies the dorsum of the patient's foot in use, said rib being formed of a flexible material that has a resilience appropriate for resisting the particular degree of plantarflexion experienced by the patient.

Description

technical field [0001] The present invention relates to ankle foot orthoses. Background technique [0002] An orthosis is a mechanical device that exerts force on a patient's limb and can be used for many different purposes. For example, an orthosis may be used for supportive, functional, corrective or protective purposes, or indeed a combination of these purposes. [0003] Ankle-foot orthoses are generally used to provide protection to a patient's ankle and foot while providing support against hyper-plantar flexion (or more colloquially referred to as "foot drop"). Plantarflexion is a medical condition caused by disease, trauma, or a congenital abnormality. Patients affected by this condition generally have difficulty walking because the patient's foot tends to droop when lifted off the ground, and the patient typically has to lift the foot higher than it should to avoid tripping. Since typical patients also tend to exhibit poor or impaired dorsiflexion, patients often a...
