Background: Studies on how the shoe insole hardness regulate joint stiffness and transfer energy in the lower extremity during jump landing are scarce. The current study aimed to determine the effectiveness of shoe insole changes in joint power and stiffness during landing from jumps. Methods: Fifteen healthy male athletes volunteered to perform jump-landing in various shoe insole conditions. ...

Although segmental tunnel linings are often used for seismic areas, the influence of segment joints on the segmental lining behavior under seismic loading has not been thoroughly considered in the literature. This paper presents the results of a numerical study investigating the effects of the rotational, axial, and radial joint stiffness of the longitudinal joints on the structural force...

introduction: the regulation of neuroendocrine axis is one of the most important goals in the treatment of rheumatoid arthritis. disease modifying drugs such as chloroquine with low dose steroid is the first choice in clinical practice by some physicians. this combination therapy is evaluated by this study. methods: this survey is a prospective study on furty patients. variables for determining...

During an earthquake, the better performance of segmental tunnel lining, compared to the continuous in-cast concrete lining, is generally related to the joints between segments. In order to better understand the influence of the segment joints, their effect on the internal forces induced in tunnel lining simultaneously with the effects of the other influential parameters should be considered. I...

Dynamic joint stiffness determines the relation between joint position and torque, and plays a vital role in the control of posture and movement. Dynamic joint stiffness can be quantified during quasi-stationary conditions using disturbance experiments, where small position perturbations are applied to the joint and the torque response is recorded. Dynamic joint stiffness is composed of intrins...

introduction: although, the effect of direct intra-articular injection of bone marrow stem cells (bmscs) on the repair of articular cartilage and the effect of elaeagnus angustifolia extract on pain relief in patients with osteoarthritis have been investigated, no studies has been conducted to compare the effects of these two therapeutic methods on the mechanical properties of articular cartila...
