Does an outdoor virtual environment projected in a head-mounted display affect balance in healthy young adults?

Background: Virtual reality head-mounted display (VR-HMD) is increasingly used for balance evaluation and rehabilitation. However, more studies must be conducted on virtual environments (VE) effects. This study aimed to assess the impact of an outdoor VE projected in a high-quality VR-HMD and of the VR-HMD mass on postural stability, postural control and leaning.

Lumbar puncture is a routine procedure frequently done in hospitalized patients. This tecnique is not free from complications. Here we bring a case of active bleeding from a lumbar arterie after a lumbar puncture that leads to hemorrhagic shock and retroperitoneal hematoma.

Is treadmill walking biomechanically comparable to overground walking? A systematic review.

Background: The equivalency of treadmill and overground walking has been investigated in a large number of studies. However, no systematic review has been performed on this topic.

Research Question: The aim of this study was to compare the biomechanical, electromyographical and energy consumption outcomes of motorized treadmill and overground walking.
