Implication

Systematic review reveals altered spinal curvature, reduced postural stability, and modified gait patterns in pregnant women, highlighting adaptive mechanisms that impact balance and back pain.

Key Points

  • To evaluate the biomechanical adaptations caused by pregnancy and determine how these alterations influence postural control, gait kinematics, back pain, and quality of life.
  • Conducted a systematic review following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
  • Identified and screened 50 eligible peer-reviewed studies retrieved from PubMed and Scopus databases.
  • Spinal lordosis and kyphosis angles increase during pregnancy across multiple studies, accompanied by a significant rise in back pain that lacks a direct correlation with spinal curvature changes.
  • Postural control decreases as demonstrated by increased centre of pressure displacement and higher stability indexes.
  • Locomotor adaptations frequently involve reduced trunk range of motion, decreased hip flexion and extension, shorter stride length, reduced gait velocity, and increased step width.
