Results of the balance test are displayed for the JUMP inactive CTRL for baseline measurements (BDC-14 and BDC-1) and the recovery phase (R+0, R+7, R+13, R+28 and R+90) after bed-rest. Values are normalized to BDC-1. Values are means ± SE.

indicates a significant difference compared to baseline. The ≈ symbol non-inferiority compared to baseline. CoF, center of force; ML, medio-lateral; AP, anterior-posterior; std., standard.
