Mobility, defined as active, controlled, multi-joint flexibility used in movement, is limited in pregnant women due to problems with low back pain (LBP) and pelvic girdle pain (PGP). The Pregnancy Mobility Index (PMI) is a tool for assessing mobility in relation to LBP/PGP. The lack of a Polish version of the PMI test prompted a transcultural adaptation to the Polish conditions. The aim of the study was to evaluate the measurement properties of the Polish adaptation of the Pregnancy Mobility Index.
The study involved 121 pregnant women aged 18-44. The translation process was in accordance with the transcultural adaptation design. Reliability was assessed by intraclass correlation coefficient (ICC). Construct validity between the Polish version of the PMI (PMI-PL) and the Physical Activity Pregnancy Questionnaire (PPAQ-PL) was assessed by Spearman's rank correlation coefficient.
The transcultural adaptation of the PMI test into Polish was satisfactory, with high internal consistency (Cronbach's alpha = 0.97-0.98, ICC = 0.989). Statistically significant inverse proportional correlations were found for total PA, total PA (light and above), light PA, moderate PA, and vigorous PA in the construct validity analysis between PMI-PL and PPAQ-PL.
The Polish version of the PMI is a reliable instrument. The introduction of a questionnaire with a classification system will make it easier for health professionals to monitor the health status of pregnant women and encourage them to engage in physical activity appropriate for their current level of mobility.
由于下背痛（LBP）和骨盆带疼痛（PGP）的问题，孕妇的活动能力（定义为主动、可控、多关节灵活性运动）受限。妊娠活动度指数（PMI）是评估与 LBP/PGP 相关活动能力的一种工具。缺乏波兰语版本的 PMI 测试促使我们对其进行跨文化适应性调整，以适应波兰的情况。本研究的目的是评估波兰语版妊娠活动度指数（PMI-PL）的测量特性。
该研究纳入了 121 名年龄在 18-44 岁之间的孕妇。翻译过程符合跨文化适应性设计。采用组内相关系数（ICC）评估可靠性。采用 Spearman 等级相关系数评估波兰语版 PMI（PMI-PL）与身体活动妊娠问卷（PPAQ-PL）之间的结构效度。
PMI 测试的波兰语跨文化适应性良好，内部一致性高（Cronbach's alpha=0.97-0.98，ICC=0.989）。在结构效度分析中，PMI-PL 与 PPAQ-PL 之间，总 PA、总 PA（轻等及以上）、轻 PA、中 PA 和强 PA 均呈显著的负相关。
波兰语版 PMI 是一种可靠的工具。引入具有分类系统的问卷将使卫生专业人员更容易监测孕妇的健康状况，并鼓励她们进行适合当前活动度水平的身体活动。
