Bed rest for pregnant women recovering from threatened abortion and premature labor to prevent abortion can cause deconditioning syndrome, but it is not clear what kind of physical exercise should be provided for these patients. To better provide appropriate rehabilitation for threatened abortion and premature labor patients, we investigated patient clinical records retrospectively. In 11 patients who were provided rehabilitation within the past three years, eight delivered during hospitalization and three became independent in ADLs and were discharged while still pregnant. All patients who delivered during their hospitalization became independent in ADLs immediately after delivery, and as a result, the maternal prognosis was good. Choosing an appropriate rehabilitation approach for patients with threatened premature labor may help alleviate their deconditioning during pregnancy without any adverse impact.
