Benefits of technology

[0008]The present invention consists of a shell, which houses front a sole lifter. Various thickness of the sole lifter is available. The unique feature of present invention is the sole lifters are always opposite to each other. The implementation of present invention employs neurobiofeed-back principle to achieve optimum correaction. A good posture would be maintained and long term outcome is very satisfactory.
[0009]Based on the inconvenience of prior art, a present invention is designed as an adjustable orthotic insole and an unique method of application, which is used to correct asymmetry and malalignment of lower extremities. If the lower extremities are well aligned and function symmetrically, the incidences of overuse injury are greatly reduced.
[0010]In order to meet the above demand, the technical means employed by present invention is to design a novel orthotic insole, which is composed of a shell and one or more sole lifter. Sole lifter corresponds to front foot or rear foot. The user applies at least one sole lifter to fulfill his / her specific demand. For instance, one foot or two feet may be applied. While the user stands on the insole, the insole provides joints optimal support, which ensues balanced muscle function. In particular, when structural asymmetry of lower extremities is present, the orthotic insole can correct the structural asymmetry. Through the corrective effect of present invention, the user may ambulate in ideal gait. Therefore, injuries associated with malalignment and asymmetry of lower extremities are prevented.

Problems solved by technology

The afflicted people are vulnerable to muscle fatigue, joint pain, as well as poor posture.
It has been well documented that poor posture is closely associated with musculoskeletal pain.
However, almost none of ideal posture has ever been found in one person.
Good posture can not be maintained without good support, which are lower extremities.
Surgery is potentially risky, and inevitably, costly.
All of the available therapeutic means have limited success and long term outcome is unsatisfactory.

first embodiment

[0029]With reference to FIG. 8, an adjustable orthotic insole in accordance with the present invention for a forefoot having a plantar surface comprises a shell (10) and a sole lifter (11). The shell (10) has a top forefoot surface. The sole lifter (11) is positioned on the top forefoot surface of shell (10) and in contact with the plantar surface of the forefoot. The sole lifter (11) and the shell (10) are produced as one solid piece, i.e. non-separable. In addition, the sole lifter (11) may be wedge-shaped, tapering from toes toward heel. The thickness of thickest end of the sole lifter (11) may varie between 0.1 cm and 1.6 cm.

second embodiment

[0030]With further reference to FIG. 9, an adjustable orthotic insole in accordance with the present invention for a rear feet near a heel having a plantar surface comprises a shell (10A) and a sole lifter (11A). The shell (10A) has a top rear foot surface. The sole lifter (11A) is positioned on the top rear foot surface of shell (10A) and in contact with the plantar surface of the rear foot near the heel. The sole lifter (11A) and the shell (10A) are produced as one solid piece, i.e. non-separable. The sole lifter (11A) may be wedge-shaped and tapering from heel toward toes. The thickness of thickest end of the sole lifter (11A) varies from 0.1 cm to 1.6 cm.

third embodiment

[0031]With further reference to FIGS. 10 and 11, an adjustable orthotic insole in accordance with the present invention for a forefoot having a plantar surface has a shell (10B) and a sole lifter (11B). The sole lifter (11B) is attached to the shell (10B) via adhesive cement and corresponds to plantar surface of the forefoot. The sole lifter (11B) may be wedge-shaped and tapering toward heel.

Abstract

An adjustable orthotic insole and a unique method of implementation has a shell and a sole lifter that is to correct malalignment of lower extremities and other functions such as cushioning, massage, etc are not anticipated. The distribution of ground reaction force is changed due to the orthotic effect of the sole lifter. A user adjusts position and thickness of the sole lifter incessantly until malalignment of lower extremities is restored to optimal alignment symmetrically. The present invention employs a unique method that the sole lifter is always opposite to rear foot lifter. Once the malalignment of lower extremities is corrected by the orthotic insole, the user would be able to maintain good posture and ambulate in ideal gait. Therefore, symmetric and coordinated movements are harmonious with balanced muscle function. The musculoskeletal system would be protected from overuse injury.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is an adjustable orthotic insole and a unique method of application, which is used to correct malalignment of lower extremities. Malaligned structures of lower extremities are predisposed to overuse injury. Therefore, a speculation is provided to prevent musculoskeletal system from overuse injuries that may be achieved through the correaction of malaligned lower extremities.[0003]2. Description of Related Art[0004]Defective structures of lower extremities are common in general population. These structural deformities include, but not limited to, lower limb length Inequality, flat foot, cavus foot, knock-knee, bow-leg, just name a few. The afflicted people are vulnerable to muscle fatigue, joint pain, as well as poor posture. It has been well documented that poor posture is closely associated with musculoskeletal pain. There is a general consensus among medical professions that it is highly unlikely...
