The relationship between biomechanical parameters and different types of posture problems in association with running is unknown. Therefore, this study aimed to investigate the excursion changes at the hip, knee, and ankle joints during running in the patients with flat foot.

The participants comprised 12 healthy men and 12 others suffering from flat feet disorder. They were divided into two experimental and control groups based on the normalized criterion of navicular. Motion excursions during the stance phase of running were calculated for all three planes of motion at the hip, knee, and ankle joints. A Vicon (200 Hz) motion analysis system with four T-Series cameras were used to measure parameters by Vicon Nexus 1.8.5, Polygon 4.1.2 software. Data were analyzed using SPSS24, and Independent sample t-test test.

There were no significant differences in all excursions of lower limb joints between the healthy and flat foot groups (P>0.05). There were significant differences observed between the healthy and flat foot groups in the dorsiflexion of the ankle (P=0.00), ankle plantarflexion (P=0. 00), hip flexion (P=0.000), hip extension (P=0.002), and knee flexion (P=0.000).

The results showed that some observed changes in excursion parameters are due to the effects of compensatory mechanisms, and some might be considered as pathologic characteristics of the flat foot. Also, flat foot had strong effects on other joints.

The aim of this study was to investigate effects of backward gait training on Excursions of Lower Limb Joints in man Patients with medial knee Osteoarthritis. The subjects were 21 healthy men and 42 male patients with knee osteoarthritis who were divided into experimental and control groups according to the Kellgren and Lawrence radiologic scale and the visual analogue scale. The experimental group performed backward gait training for six weeks. A Vicon (130 Hz) motion analysis system with four T-Series cameras were used to measure parameters by Vicon Nexus 1.8.5, Polygon 4.1.2 software. There were no significant differences in all kinematics parameters (joint angles) between the healthy and KOA groups (P>0.05). There were significant differences observed between groups of patients and healthy subjects (patients & health) for knee flexion/extension excursion (P=0.014, P=0.047), hip Internal/external rotation excursion (P=0.014, P=0.047) and the visual analogue scale(P=0.00, P=0.00) Significant influence of exercise on increasing the rate of anterior/posterior pelvic tilt the experimental group compared with control groups (P=0.028, P=0.026). There were significant differences observed between groups of control and intervention for the visual analogue scale. Some of the observed changes in kinematics parameters are due to effects of compensatory mechanisms, and some of them might be considered as the severity of the OA. In addition, OA in one joint had strong effects on other joints. Backward gait training protocol had a significant effect on knee/ hip excursions and reduction of pain.
