Observational Study
Effect of soft and semirigid ankle orthoses on Star Excursion Balance Test performance in patients with functional ankle instability.
To evaluate the effect of soft and semirigid ankle orthoses on dynamic balance assessed using Star Excursion Balance Test in patients with functional ankle instability compared with healthy individuals. ⋯ Ankle orthoses improve reach distance in functional ankle instability patients in various reach directions. Soft orthosis has a more pronounced effect on dynamic balance, especially in posteromedial direction, compared with semirigid orthosis.

Tendinopathy is a common, costly condition affecting both sporting and sedentary populations. Research into tendinopathy frequently involves the evaluation of tendinosis, a pathology characterized by a lack of inflammatory cells, collagen disruption, neovascularisation, altered cell numbers and morphology and increased glycosaminoglycans. Evaluation of these characteristics can be undertaken using the Bonar histopathology score, but the characteristics are heterogeneous throughout tendon specimens with no standardized method of determining the area to be evaluated. The objective of this study was to assess whether the Bonar score varies depending on the criteria used to define the area of evaluation. ⋯ The updated Bonar score includes a standardized method of selecting the area of evaluation, which should provide increased reliability when assessing the extent of tendon degeneration.

This study aimed to investigate kinematic changes experienced during running-induced fatigue. Further, the study examined relations between kinematic changes and core endurance. ⋯ Novice runners displayed an overall increase in trunk inclination and increased ankle eversion peak angles when fatigued utilizing a running-induced fatigue protocol. As most pronounced changes were found for the trunk, trunk kinematics appear to be significantly affected during fatigued running and should not be overlooked. Core endurance measures displayed unexpected relations with running kinematics and require further investigation to determine the significance of these relations.
