• Description:
  This study aimed to evaluate the accuracy of 3D L5/S1 moment estimates from a wearable inertial motion capture system during manual lifting tasks. Reference L5/S1 moments were calculated using inversed ynamics bottom-up and top-down laboratory models, based on the data from a measurement system comprising optical motion capture and force plates. Nine groups of four subjects performed tasks consisting of lifting and lowering 10 lbs. load with three different heights and asymmetry angles. As a measure of system performance, the root means square errors and absolute peak errors between models were compared. Also, repeated measures analyses of variance were calculated comparing the means and the absolute peaks of the estimated moments. The results suggest that most of the estimates obtained from the wireless sensor system are in close correspondence when comparing the means, and more variability is observed when comparing peak values to other models calculating estimates of L5/S1 moments.
