Description

Ankle-foot orthosis

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an ankle-foot orthosis.

Background

Ankle-foot orthoses, also known as lower-leg orthoses, are commonly used to provide protection for a patient's ankle and foot, while providing support against excessive plantarflexion (or more colloquially "foot drop"). Plantar flexion is a medical condition caused by disease, trauma, or congenital abnormalities. Patients infected with this condition typically have difficulty walking because the patient's feet tend to drop when lifted off the ground, and thus the patient typically has to lift the foot higher than it should to avoid tripping over. It is also common for patients to have problems during the swing phase of the gait cycle, as patients also typically tend to exhibit poor or impaired dorsiflexion. The primary function of an ankle-foot orthosis is to provide a resistance to plantarflexion which helps the foot of the patient to remain in the correct position when the foot is lifted off the ground. In addition to this resistance function, a good ankle-foot orthosis should also provide a degree of assistance to dorsiflexion during the swing-through phase of the patient's gait. For example, chinese patent application No. cn200580046560.x discloses an ankle-foot orthosis. A preferred embodiment of the utility model provides an ankle-foot orthosis for resisting plantarflexion of a patient's foot, comprising a flexibly resilient sock-like orthotic structure formed by first and second tubular portions set at an angle to one another, wherein the second tubular portion is openable for insertion of the patient's foot and lower leg into the first and second tubular portions respectively, the orthosis further comprising at least one closure member which can be passed around at least a portion of the circumference of the second tubular portion and secured in position to urge the second tubular portion towards a closed position in which it fits closely to the lower leg of the patient. The first tubular portion of the above patent is used to support the foot, and is also prone to foot drop due to the weight of the ball of the foot during use, with a slight orthotic effect.
