What is W sitting?
W sitting is a position that describes the direction of the lower extremities (legs). It is called a W as a result of the legs being bent at the knee, the lower legs and feet outside of the hips, and behind the child. When standing above the child and looking down, the legs form a W.
Is W sitting normal?
W sitting is common amongst children. It occurs due to children, having flexibility in the lower extremities. However, when a child is in the W seated position it is evidence of weak core and trunk muscle. These muscles are required to sit with legs forward or bend. Another sign core and trunk weakness is a rounded back when a child does have Legs forward. If a child lacks core/trunk muscle engagement, sitting in a W position provide them with more stability.
How to correct:
There are several strategies and activities that can correct this position and strengthen the muscles required. 1 strategy is to utilize a specific phrase to request a child to move their legs forward. When this phrase is utilized consistently over time, a child will fade out of sitting in the W position. Another strategy to incorporate is to provide opportunities for a child to engage in activities while seated in a chair. The chair is required to support the 90-90-90 position, which is when the hips, knees, and ankles are in a 90° position. A third strategy to utilize is engaging in activities while lying in prone extension (lying on the stomach). A child can lay on their stomach on the floor, a platform swing, a scooter board, a peanut ball, an exercise ball, etc. Some activities to practice are exercises, such as: sit-ups, planking, and balancing.
