“Regardless of age, the mean CoP velocity was greater when standing upstairs (11.1 ± 3.5 mm s−1) than downstairs (9.0 ± 2.3 mm s−1; p = 0.002).”

What did studies of Standing at the top of a staircase find?

3

Studies of Standing at the top of a staircase measured 3 outcomes; the most studied are motor evoked potential amplitude (1 study), H-reflex amplitude (1) and center of pressure velocity (1).

Motor evoked potential amplitude

no changein humans1

1 study

  1. Standing at the top of a staircase has no effect on motor evoked potential amplitude in humans (p > 0.05).

    “no significant difference was observed in MEP amplitude and silent period between balance conditions (p > 0.05).”

H-reflex amplitude

downin humans1

1 study

  1. Standing at the top of a staircase decreases H-reflex amplitude in humans (-30.6%, p < 0.001).

    “In both groups, the H 50 amplitude (-30.6%; p < 0.001) and slope of H-reflex input-output relation (-10.2%; p = 0.002) were lesser when standing upstairs than downstairs”

1 study

  1. Standing at the top of a staircase increases center of pressure velocity in humans (11.1 ± 3.5 mm s−1 vs 9.0 ± 2.3 mm s−1, p = 0.002).

    “Regardless of age, the mean CoP velocity was greater when standing upstairs (11.1 ± 3.5 mm s−1) than downstairs (9.0 ± 2.3 mm s−1; p = 0.002).”
