This is a method development and validation study. ⋯ The ankle-worn accelerometer provided the most accurate step count, but wrongly registered steps during nonwalking activities. The developed step detection method shows potential as a measure of walking activity why further development and testing under free-living conditions should be performed.

Laboratory study. ⋯ Load direction plays a subordinate role in traumatic fractures of the odontoid process. BMD was associated with significant correlation to the biomechanical outcomes. Thus, odontoid fractures appear to result from of an interaction between the load magnitude and bone quality.

The effect of amlodipine (AM) on spinal cord injury (SCI) and autophagy was researched by establishing ventral spinal cord cells (VSC4.1) oxygen and glucose deprivation model and SCI mice model. ⋯ AM inhibited motoneuronal apoptosis by upregulating autophagy to improve SCI recovery.
