    Insufficient leg length can cause the user to slump forward or experience posterior pelvic tilt, contributing to spinal misalignment and back pain. Excessive leg length, on the other hand, can cause pressure behind the knees, restricting circulation and potentially leading to skin breakdown. A properly measured leg length promotes neutral pelvic positioning and proper spinal alignment.

  • Knee and Hip Joint Health

    Inadequate or excessive leg length can strain the knee and hip joints. Too short a distance can result in increased knee flexion, while too long a distance can lead to knee hyperextension. Optimal leg length minimizes stress on these joints, promoting comfort and preventing long-term damage. Furthermore, it influences overall functional mobility and ease of transfers.

  • Footplate Adjustment and Customization

    Leg length measurements directly dictate the correct footplate setting. Adjustable footplates allow for fine-tuning to accommodate variations in leg length, ensuring proper support and positioning. Custom footplates can further enhance comfort and accommodate specific foot or ankle deformities, maximizing user comfort and stability within the wheelchair.

Precise leg length measurement plays a pivotal role in achieving a well-fitted wheelchair, contributing to postural stability, pressure redistribution, and overall user comfort.
