Szczegółowy opis
This study investigates the feasibility and potential benefits of a specifically designed exercise program for hospitalized high-risk pregnant individuals on bed rest. The program includes resistance and strength exercises tailored to be safely performed while in bed, aiming to counteract the physiological and psychological deconditioning associated with prolonged inactivity during hospitalization.
Prolonged bed rest during pregnancy, often prescribed for high-risk conditions, can result in muscle atrophy, reduced cardiovascular capacity, and psychological distress, including anxiety, stress, and depression. Despite the known adverse effects of inactivity, there is limited evidence on structured exercise programs for this population. This study seeks to fill that gap by testing an intervention designed to mitigate these negative outcomes.
Participants will be randomized into two groups: an exercise group (EG) and a no-exercise group (NEG). The EG will perform daily supervised exercises, lasting approximately 30 minutes, under the guidance of trained staff. The NEG will follow standard care without structured physical activity. The study evaluates physical health parameters (e.g., activity levels, muscle strength), mental health outcomes (e.g., anxiety, depression, stress), sleep quality, and quality of life. Secondary objectives include assessing program feasibility, recruitment rates, adherence, and participant satisfaction.
Data collection will include validated self-reported questionnaires, wearable devices (accelerometers), and clinical measures. Key endpoints will be compared between groups at regular intervals during hospitalization and at six weeks postpartum.
This pilot randomized controlled trial aims to generate knowledge on the acceptability, safety, and preliminary effectiveness of bed-rest exercise programs in high-risk pregnancies, with the goal of informing future larger-scale studies and addressing an unmet need in maternal care.

Baseline Maternal and fetal characteristics: Evaluation of physical activity (GAQ-P questionnaire)
Ramy czasowe: Baseline
|
The questionnarie self-clasisfies how often and for how long the participant engages in light-, moderate-, or vigorous-intensity physical activity.
It also assesses whether the participant should consult her obstetric health care provider before beginning or continuing physical activity during pregnancy.
The GAQP is a screening and classification tool and does not generate a numerical summary score.
Therefore, no minimun or maximum applies, and higher or lower scores do not indicate a better or worse outcome.
