The purpose of this study was a comprehensive assessment of the dynamic parameters of gait in patients who underwent Ilizarov treatment for nonunion of the tibia. The experimental group consisted of 24 individuals treated with the Ilizarov method for nonunion of the tibia. The control group comprised 31 healthy individuals, matched for BMI, sex, and age. The dynamic gait parameters in patients and in the control group were measured with a Zebris pedobarographic platform. The treatment group and the control group showed statistically significant differences in terms of the following gait parameters: maximum force during braking nonoperated-limb (NOL), time maximum force during braking operated-limb (OL), time maximum force during braking NOL, maximum force during push-off NOL, time maximum force during push-off OL, and maximum force forefoot OL. Most of the evaluated gait parameters were bilaterally similar in patients group. The only significant differences between the operated and nonoperated limb were seen in terms of Time maximum force during push-off and Maximum force forefoot. The most pronounced abnormalities in dynamic gait parameters were observed in the forefoot (maximum force forefoot OL was 13.3% lower than in the control group, maximum force forefoot OL was 12.4% lower than in NOL). The patients treated with the Ilizarov method did not achieve a complete normalization of dynamic gait parameters, as their gait parameters did not equal those measured in the control group. The Ilizarov method for the treatment of tibial nonunion helps restore a symmetrical distribution of gait parameter values between the affected limb and the healthy limb. Patients continue to show the following abnormalities in their dynamic gait parameters after treatment: higher values maximum force during braking NOL, Time maximum force during braking OL, time maximum force during braking NOL, maximum force during push-off NOL, contact time forefoot NOL, contact time midfoot NOL, contact time heel NOL and smaller values of time maximum force during push-off OL.

Thermoresponsive shape memory polymer (SMP) adhesives have demonstrated a high adhesion strength and large switching ratios on different substrates. However, a long response time to switch adhesion on or off is generally encountered. This study provides a fast adhesion switching method based on the temperature and rate dependence of adhesion within the glass-transition zone of an epoxy polymer.

The present work reports a clear and improved hydrothermal methodology for the synthesis of MoSe nanoflowers (MNFs) at 210 °C. To observe the effect of temperature on the fascinating properties, the process temperature was modified by ±10 °C. The as-prepared MNFs were found to consist of 2D nanosheets, which assembled into a 3D flower-like hierarchical morphology van der Waals forces.

Potassium is a harmful impurity in the rhenium sinter, which adversely affects its mechanical properties by significantly reducing the density of sintered rhenium. Cationic resin is a promising material for potassium removal. In this study, the strong acid cationic exchange resin C160H was pretreated with an HNO solution to enhance its performance in potassium removal.

Introduction: The bilateral deficit (BLD) is a reduction in the amount of force during a bilateral task vs. the total force from the unilateral limbs performing the same task. We quantified the BLD during an upper body Wingate Anaerobic Test (WAnT) and evaluated the influence of sex and load on the BLD in force.

Introduction: Restricted mouth opening has major health implications, such as malnutrition, difficulty in speech, and poor oral hygiene resulting in a functional shortage of the masticatory system. Reduced mouth opening can occur due to trismus, as in the oral submucous fibrosis (OSMF) condition. Excision of fibrous bands in OSMF leads to reestablishment of the mouth opening.
