Obliquity and rotation of the pelvis
Obliquity of the pelvis
Rotation
Uncorrected posture
Corrected posture – a 2-point belt
Uncorrected posture
Corrected posture – a 4- point belt
ASSESSMENT
One side of the pelvis is usually higher than the other one.
Usually involves rotation.
Shoulder on the low side of the pelvis tends to be elevated.
CAUSES
Wheelchair: wheelchair too wide, seat too short
Physical conditions: irregular trunk muscle tone, muscle
imbalance, scoliosis.
PURPOSE OF THE BELT AND HOW TO USE IT
Position the belt over the ASIS and attach at 60° to the seat.
When using a four-point belt, anchor the secondary straps to the
seat at 45° to 90°.
NOTE
Obliquity and rotation of the pelvis usually seen as increased
pressure during active movement can often be reduced by an
asymmetrical attachment of the belt to the wheelchair. Adjust the
position of each anchor point to optimize the pull against each
side of the pelvis.
WHY TO USE THE BELT
The belt is designed to bring the pelvis down to the seat and back
to the backrest.
