How is the average back height of a wheelchair determined?

From the seat of the chair to the shoulder height
From the seat of the chair to the floor of the axilla, then subtracting four inches
From the seat of the chair to the top of the head
From the popliteal fold to the axilla

The correct answer is: From the seat of the chair to the floor of the axilla, then subtracting four inches

The average back height of a wheelchair is determined by measuring from the seat of the chair to the floor of the axilla (the underarm area) and then subtracting four inches. This adjustment takes into consideration the mobility and comfort of the user. By subtracting four inches, the design ensures that the backrest adequately supports the individual while also allowing for enough freedom of movement in the upper body. This method is widely accepted for achieving a balance between support and functional mobility, particularly in facilitating arm movements during daily activities.
