Key result
Shoulder-out water immersion in pregnant women significantly increased urine output from 92 ml/hr to 185 ml/hr and urinary sodium excretion, whereas lower body positive pressure had no significant effect.

Does shoulder-out immersion or lower body positive pressure increase diuresis and natriuresis in pregnant women?
Shoulder-out immersion exercise induces significant diuresis and natriuresis in pregnant women, suggesting potential therapeutic utility for managing abnormal water distribution.
In the laboratory, water immersion or lower body positive pressure produces significant diuresis and natriuresis. Shoulder-out immersion appeared to induce significant diuresis and natriuresis in 42 pregnant women who were exercising in swimming pools. Lower body positive pressure (pressure calf sleeves) or Hubbard tanks (bathtubs) was not associated with increased renal function. In selected pregnant women with abnormal water distribution, shoulder-out immersion may prove to be effective therapy.

Goodlin et al. (1984) conducted an observational in Pregnancy (including normal, hypertension, and preeclampsia) (n=57). Shoulder-out water immersion vs. Pre-immersion baseline was evaluated on Urine output (p=<0.02). Shoulder-out water immersion in pregnant women significantly increased urine output from 92 ml/hr to 185 ml/hr and urinary sodium excretion, whereas lower body positive pressure had no significant effect.
