Accelerometry to detect motor deficits in children


  • Bilateral upper extremity (UE) movement measured by accelerometry can be used to measure motor activity in children, and the mono-arm use index (MAUI) and bilateral-use arm index (BAUI) may be more efficient at detecting subtle motor deficits in children than the use ratio (UR).

Why this matters

  • Screening young children for motor deficits remains a challenge, and accelerometry may be useful as a tool to detect deficits in children at risk for asymmetrical deficits.
