Background. The sensomotor insole (SMI) has clinically been shown to be successful in treating an intoeing gait. We investigated the biomechanical effect of SMI on a pediatric intoeing gait by using three-dimensional gait analysis. Methods. Six patients with congenital clubfeet and four patients with idiopathic intoeing gait were included. There were five boys and five girls with the average ag...

Introduction: Knowledge of accurate in-vivo kinematics of total hip arthroplasty (THA) during daily activities is critical for gaining insights into complications such as hip impingement, edge loading, wear and implant loosening. Previous studies have reported hip separations up to 3 mm in patients with metal-on-polyethylene (MoP) THA during the swing phase of gait. However, no studies evaluate...

[Purpose] This study evaluated gait parameters and foot pressure in two regions of the feet among older females with different personal care support needs to analyze factors that contribute to higher support requirements. [Subjects and Methods] Thirty-two older females were divided into support-need and care-need level groups. Gait parameters (speed, cadence, step length, step width, gait angle...

in this study, a new servo control system is presented for the overhead crane based on discrete-time state feedback approach. it provides both robust tracking and load swing suppression. inspired from independent joint and computed torque control in robot manipulator field, a new model is derived in which the crane actuators are considered as the main plant. the crane nonlinearities are then tr...

Background. Stair climbing is often performed by people in daily life and requires considerable energy muscle effort. This task has been widely described the literature, but role of knee joint ligaments not sufficiently investigated. could be relevant for planning ligament reconstruction surgery, providing suggestions to subjects with partial injuries, identifying compensatory strategies reduci...

introduction: the aim of this study was to determine which technique of uncinectomy, classical or swing door technique.  materials and methods: four hundred eighty cases of sinusitis were selected and operated for functional endoscopic sinus surgery (fess). out of these, in 240 uncinectomies classical uncinectomy was done whereas in another 240 uncinectomies swing door technique was used. initi...

Introduction: Posterior-stabilized total knee arthroplasty (TKA) has been widely used since its introduction nearly three decades ago, and long-term follow-up studies have reported satisfactory results. However, mechanical failure due to fracture of the tibial post recently has been described in several reports (1). The possible fracture mechanism was the repeated impingement between the interc...

Recent data from this laboratory on differential controls for the shoulder, elbow, and wrist exerted by the thalamo-cortical network during locomotion is presented, based on experiments involving chronically instrumented cats walking on a flat surface and along a horizontal ladder. The activity of the following three groups of neurons is characterized: (1) neurons of the motor cortex that proje...

The relationships between extrinsic forces acting at the knee and knee kinematics were examined with the purpose of identifying specific phases of the walking cycle that could cause abnormal kinematics in the anterior cruciate ligament (ACL) deficient knee. Intersegmental forces and moments in directions that would produce anterior-posterior (AP) translation, internal-external (IE) rotation and...
