The modified version of the BMEC was selected to assess the practical component of body mechanics (3).
Participants of the back school program completed the Spanish version of the ABSPT and the physical therapist evaluated the lifting activity using the BMEC at baseline.
Additionally, the physical therapist offered feedback to participants during performance of the lifting activity, and after scoring on the BMEC of the posttest as required by the back school program.
The Standard Error of Measurement (SEM) for the BMEC was determined by using the following formula: standard deviation ([square root of] 1.
The test-retest reliability for the modified version of the BMEC yielded an ICC of 0.
First, the BMEC instrument exhibited good day-to-day stability as an assessment tool for evaluating the application of appropriate body mechanics during a lifting activity.
The model (3,1) used to estimate the ICC for the modified version of the BMEC does not allow generalization to a population of physical therapists different from the one in this study.
