From the Research
The W-sitting position poses minimal risk for most healthy children, and current medical evidence suggests that fears of it causing hip dysplasia, muscle tightness, or delayed motor skills are largely unfounded. According to a systematic review published in 2024 1, there is no scientific evidence to advise against W-sitting in children, and no association with hip dysplasia was found. Most children naturally move in and out of various sitting positions, including the W position, without developing problems. However, if a child sits exclusively in the W position and shows signs of muscle tightness, poor balance, or coordination issues, parents might encourage alternative sitting positions like cross-legged, side-sitting, or long-sitting. For children with existing orthopedic conditions or developmental concerns, consulting with a pediatrician or physical therapist is advisable. Generally, allowing children to move naturally between different positions during play supports normal development of strength, balance, and coordination.
Some key points to consider:
- The review found no causal relation between W-sitting and developmental dysplasia of the hip 1.
- Muscular activation remains the same, regardless of the position chosen for sitting 1.
- Allowing children to move naturally between different positions during play supports normal development of strength, balance, and coordination.
- For children with existing orthopedic conditions or developmental concerns, consulting with a pediatrician or physical therapist is advisable.
It's worth noting that other studies, such as those on musculoskeletal pain 2, knee pain evaluation and treatment 3, and musculoskeletal disorders 4, do not provide direct evidence related to the W-sitting position in children. However, a clinical practice guideline for physical therapy in patients with hip or knee osteoarthritis 5 emphasizes the importance of individualized assessment and treatment, which may be relevant for children with existing orthopedic conditions. Overall, the current evidence suggests that W-sitting is not a significant risk factor for healthy children, and parents should focus on encouraging natural movement and development.
