Purpose: Supination trauma is a common sports injury, and often leads to chronic ankle instability. This study analyses whether indications of healing can be detected 2 weeks after supination trauma.

Methods: This prospective, monocentric study at a German Medical Center examined patients with acute supination trauma.

Ankle sprains are the most frequently occurring musculoskeletal injuries among recreational athletes. Ankle support through bandages following the initial orthotic treatment might be beneficial for rehabilitation purposes. However, the literature is sparse regarding the use of an ankle support directly after the acute phase of an ankle sprain.

Anterior cruciate ligament reconstruction (ACLR) may affect movement even years after surgery. The purpose of this study was to determine possible interlimb asymmetries due to ACLR when running on a treadmill and in field conditions, with the aim of contributing to the establishment of objective movement assessment in real-world settings; moreover, we aimed to gain knowledge on recovered ACLR as a biomechanical risk factor. Eight subjects with a history of unilateral ACLR 5.

Foot rollover and the 'ride' feeling that occurs during heel-toe transition during running have been investigated mostly in laboratory settings due to the technical requirements of 'golden standard' measurement devices. Hence, the purpose of the current study was to investigate 'ride' and rollover with a heel cap-mounted inertial measurement unit (IMU) when running under field conditions to get realistic results. Twenty athletes ran on a 1 km outdoor track with five different shoe conditions, only differing in their midsole bending stiffness.

The purpose of this study was to determine the influence of footwear stiffness and energy loss on oxygen uptake and heart rate in athletes running under aerobic and anaerobic conditions. Four footwear conditions with identical outsoles, insoles, upper materials, but different mechanical properties regarding polyurethane midsole materials were investigated. Respective midsole material characteristics were selected to represent a wide range of running shoes.

Article Synopsis
  • Previous studies examined how different operating ranges (ORs) of accelerometers affect the accuracy of running measurements like stride length and running velocity, but their impact is still uncertain.
  • The current study tested 21 recreational heel strike runners on a 15-meter track using various midsole stiffnesses in their footwear and combined different ORs when analyzing data from accelerometers placed on the runners.
  • Results indicated that lower ORs led to significant underestimations of biomechanical parameters, suggesting that accelerometers should have at least a ±32 g OR for accurate measurements.

Increasingly, inertial sensors are being used for running analyses. The aim of this study was to systematically investigate the influence of inertial sensor sampling frequencies (SF) on the accuracy of kinematic, spatio-temporal, and kinetic parameters. We hypothesized that running analyses at lower SF result in less signal information and therefore the inability to sufficiently interpret measurement data.
