    Range of motion and plantar pressure evaluation for the effects of self-care foot exercises on diabetic patients with and without neuropathy
    (American Podiatric Medical Association, 2016) Cerrahoglu L.; Koşan U.; Sirin T.C.; Ulusoy A.
    Background: We aimed to investigate whether a home exercise for self-care program that consists of range of motion (ROM), stretching, and strengthening exercises could improve ROM for foot joints and plantar pressure distribution during walking in diabetic patients to prevent diabetic foot complications. Methods: Seventy-six diabetic patients were recruited (38 with neuropathy and 38 without neuropathy). Neuropathy and nonneuropathy groups were randomly divided into a home exercise group (n ¼19) and a control group (n ¼ 19). Exercise groups performed their own respective training programs for 4 weeks, whereas no training was done in the control group. Total contact area and plantar pressure under six foot areas before and after the exercise program were measured. Ankle and first metatarsophalangeal joint ROM were measured before and after the exercise program. Results: In the exercise group, there were significant improvements in ROM for the ankle and first metatarsophalangeal joints (P <.001); static pedobarographic values showed significant reduction in right forefoot-medial pressure (P ¼.010); and significant decreases were seen in dynamic pedobarographic values of peak plantar pressure at the left forefoot medial (P ¼.007), right forefoot lateral (P ¼.018), left midfoot (P <.001), and right hindfoot (P ¼.021) after exercise. No significant positive or negative correlation was found between the neuropathy and nonneuropathy groups (P >.05). Conclusions: A home exercise program could be an effective preventive method for improving ROM for foot joints and plantar pressure distribution in diabetic patients independent of the presence of neuropathy. © 2016, American Podiatric Medical Association.

    Comparison of biomechanical effects of different configurations of kirschner wires on the epiphyseal plate and stability in a salter-harris type 2 distal femoral fracture model
    (American Podiatric Medical Association, 2019) Inal S.; Gok K.; Gok A.; Pinar A.M.; Inal C.
    Background: We sought to investigate the different configurations of Kirschner wires used in distal femur Salter-Harris (SH) type 2 epiphyseal fracture for stabilization after reduction under axial, rotational, and bending forces and to define the biomechanical effects on the epiphyseal plate and the fracture line and decide which was more advantageous. Methods: The SH type 2 fracture was modeled using design software for four different configurations: Cross, cross-parallel, parallel medial, and parallel lateral with two Kirschner wires, and computer-aided numerical analyses of the different configurations after reduction were performed using the finite element method. For each configuration, the mesh process, loading condition (axial, bending, and rotational), boundary conditions, and material models were applied in finite element software, and growth cartilage and von Mises stress values occurring around the Kirschner wire groove were calculated. Results: In growth cartilage, the stresses were highest in the parallel lateral configuration and lowest in the cross configuration. In Kirschner wires, the stresses were highest in the cross configuration and lowest in the cross-parallel and parallel lateral configurations. In the groove between the growth cartilage and the Kirschner wire interface, the stresses were highest in the parallel lateral configuration and lowest in the cross configuration. Conclusions: The results showed that the cross configuration is advantageous in fixation. In addition, in the SH type 2 epiphyseal fracture, we believe that the fixation shape should not be applied in the lateral configuration. © 2019, American Podiatric Medical Association.
