Analysis of Free-Living Mobility in People with Mild Traumatic Brain Injury and Healthy Controls: Quality over Quantity.

摘要: Balance and mobility issues are common non-resolving symptoms following mild traumatic brain injury (mTBI). Current approaches for evaluating balance an mTBI can be subjective suboptimal as they may not sensitive to subtle deficits, particularly in those with chronic mTBI. Wearable inertial measurement units (IMU) allow objective quantification of continuous outcomes natural free-living environments. This study aimed explore (physical activity turning) healthy (mTBI) participants using a single IMU. Free-living was examined 23 control (48.56 ± 23.07 years) 29 symptomatic (40.2 ± 12.1 (average 419 days post-injury, persistent complaints) over 1 week, IMU placed at the waist. characterized terms macro volume, pattern variability) micro-level (discrete measures features. Macro-level showed had similar quantities compared controls. Micro-level within walking bouts that impaired quality mobility. Specifically, people made larger turns, longer turning durations, slower average peak velocities (all p < 0.001), greater turn variability Results highlighted rather than quantity differentiated from Our findings support use monitoring enhance understanding specific mTBI-related deficits. Future work is required develop optimal battery across spectrum aid application clinical practice.
