Leg length discrepancy corrective sock

Abstract

The present invention provides a leg length discrepancy corrective sock, which has an elastic strip attached within a sock. A holding space formed between a sock body and a sock sole of the sock and the elastic strip provides for disposing a filler therein, and height of the filler achieves the objective of correcting the difference in length of the lower limbs of the leg length discrepancy sufferer. Hence, equalizing the difference in length of the lower limbs is easily achieved by wearing the leg length discrepancy corrective sock of appropriate thickness.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a leg length discrepancy corrective sock, which has an elastic strip attached to a sock body and a sock sole of a sock, thereby forming an opening on the sock body. A filler is inserted into the opening and disposed within a holding space, thereby elevating the elastic strip above the sock sole to accord with the difference in length of the lower limbs of the leg length discrepancy sufferer, which thus achieves objective of correcting the leg length discrepancy. [0003] The filler is made from soft material, and when a leg length discrepancy sufferer is wearing the corrective sock of the present invention, apart from sharing the pressure burden on the foot resulting from the discrepancy in length of the two legs, the filler further alleviates pressure endured by the spine, thereby improving the degree of comfort when wearing the corrective sock, as well as equalizing the difference i...

AI Technical Summary

Benefits of technology

[0012] The present invention is characterized in that the elastic strip having good soft and elastic properties is attached to the sock body and the sock sole within the sock, thereby forming a holding space having an opening. The filler is inserted into the opening and disposed within the holding space, thereby elevating the elastic strip above the sock sole to accord with the difference in length of the lower limbs of the leg length discrepancy sufferer, which thus achieves objective of correcting the leg length discrepancy.

[0013] The filler is made from soft material, and when a leg length discrepancy sufferer is wearing the sock of the present invention, apart from sharing the pressure burden on the foot resulting from the discrepancy in length of the two legs, the filler is also able to alleviate pressure endured by the spine, thereby improving the degree of comfort when wearing the sock. Furthermore, an interior of the filler holds air, liquid or related filler fluids, and the filler can be fitted as a fixed volume with an adjustable inner filler material that transforms the volume.

Problems solved by technology

The high percentage of children and youngsters in Taiwan suffering from lateral spinal curvature can be mainly attributed to leg length discrepancy, which not only seriously affects the lifestyle of the sufferers, but also means those seriously affected undergoing a surgical operation to remedy their ailment.

Moreover, if the sufferer normally stands or walks for long periods of time in their daily work, for instance, teachers, attendants, salespeople, police, nurses, sportspeople, and so on, and if the difference in length between their two legs is 3-5 mm, then the person is even more likely to suffer from lumbago and lower back pains when compared to non-sufferers of leg length discrepancy.

However, because of the uneven weight of the shoes on the two feet, a child or youngster wearing the shoe A having a number of layers of soles A1 very easily stumbles or results in an unsteady center of gravity when walking.

Furthermore, height adjustment of the sole A1 is difficult, and different discrepancies in length between the two legs and change in length of the legs during a rehabilitation process results in inability to accurately match the sole A1 appropriate to the length discrepancy.

Furthermore, because the length of time the leg length discrepancy sufferer wears a shoe having an added insole or a high sole shoe everyday is limited, thus, effectiveness of correcting leg length discrepancy is correspondingly limited.

Moreover, when the leg-discrepancy sufferer has occasion to take off his shoes, apart from the embarrassment of a limp resulting from his leg length discrepancy and the unusual expression in the eyes of other persons or their abnormal concern distressing the sufferer, moreover, he incurs heartless secondary harm both psychologically and to his self-esteem.
