| Popis: | It is known that the deformities that affect the lower limbs are multiple in terms of location and severity of the injury. These deformities are treated with the use of orthosis, which varies depending on the type of deformity and the area of injury. The principle on which the orthosis depends on the treatment of deformities is applying three-point pressures. These pressures are applied during the manufacturing process of the orthosis but with the time when the deformation response to treatment by corrected forces these mean the value and location of these corrective forces will change and this requires the manufacturing of a new orthosis. This requires costs in money and time to re-correct these forces. In this study, a force correction system was suggested that could change the value and location of corrective forces without need to manufacture a new orthosis and within a few minutes by placing an air chamber on the side of the orthosis. When increasing or withdrawing the amount of air inside the air chamber, the magnitudes of corrected force change according to the required value, this process providing comfort to the patient and reducing the effort of the professional staff supervisor (orthotist) to correct the deformity. The result showed that a method of correction forces applied by using the air chamber to correct deformities was successful when applied to a patient with varus foot deformity where the pressure generated from the air chamber on the leg was measured by using the F-Socket devise at the lateral side recorded a higher interface pressure (140Kpa) than the others sides due to pump the air to push the ankle joint for correction deformity without needing to manufacture of a new orthosis to change the values of correction forces thus reducing the cost and time to treat deformity, also the result showed improvement of the gait cycle, the value of ground reaction force on the body and footprint of the patient when comparing the results before and after the use of the orthosis by the patient. |
