Do temporal patterns of the trunk muscles remain altered in a low back-injured population despite subjective reports of recovery?
Despite perceived readiness to return to work and low pain scores, muscle activation patterns remained altered in this LBI group, including reduced synergistic coactivation and increased overall amplitudes as well as greater relative amplitude differences during specific phases of the movement. Electromyographic measures provide objective information to help guide therapy and may assist with determining the level of healing and return-to-work readiness after an LBI.
Capnometry readings upon arrival to the ED did not predict hospital admission or hospital discharge eligibility. Among hospitalized patients, EtCO2 did not correlate with the evaluated disease severity measures. Wang score was found to be the most consistent predictor of significant outcomes.
