Pregnancy induces hormonal and biomechanical adaptations that increase ligamentous laxity, which may persist into the postpartum period and contribute to joint instability, pain, and functional limitations. Although prenatal Pilates has been shown to prevent the progression of ligamentous laxity during pregnancy, its effects on postpartum musculoskeletal recovery remain unclear. This longitudinal follow-up of a randomized controlled trial evaluated ligamentous recovery at 6 weeks postpartum in women who participated in a structured prenatal Pilates program continued until childbirth, compared with women receiving standard prenatal care. Postpartum ligamentous laxity, generalized joint hypermobility, and activity limitations related to pelvic girdle pain were assessed using objective and clinical measures. The study aimed to determine whether prenatal Pilates facilitates early postpartum ligamentous recovery and supports functional outcomes during the early postpartum period.

Inclusion Criteria:

• Aged between 18-35 years
• In the 6th week of post-partum
• Voluntary participation in the study

Exclusion Criteria:

• Cardiovascular or pulmonary diseases
• Prior participation in structured physical activity programs

Female

The study population consisted of postpartum women aged 18-35 years who were 6th week after delivery and who voluntarily agreed to participate in the study. Women with known cardiovascular or pulmonary diseases, and those who had participated in structured physical activity programs prior to enrollment were excluded. These criteria were applied to ensure a homogeneous sample and to minimize potential confounding factors related to pre-existing health conditions or prior exercise exposure.
