N/A DROP FOOT. Intervention 1: Intervention group 1: drop foot people will walk while wearing modified neoprane orthose in their shoes on kistler force plate to predict the components of the kinetic and kinematic gait . The test process will be explained to the patient and they have to walk with both orthoses for 10 min . After being situated in the corresponding calibration the markers will be placed on bony landmarks and the person starts to walk. In order to detect the markers, the subject wore black trousers, nightwear and light reflective markers will be placed on the fifth metatarsal head, internal and external ankle, tubrasity of calcaneus, medial and latral condyle of femur for both feet. Even the study of the digital camera in the direction of movement is marked and moves will be recorded. The best example of the 3 modes will be selected. The data from these tests will be compared first together and then to the normal foot. Intervention 2: Intervention Group 2:The Test Will Be Taken While They'll Be Wearing Solid AFO With Their Shoes. Intervention 3: Intervention Group 3: The Test Will Be Taken Barefoot.
