Thomas test:
The Thomas test is a method to determine the range of motion of the hip and, in particular, a hip flexion contrac-
ture
1 To determine the extent of hip flexor contracture, the patient lies on an examination table or other level surface
without their prosthesis
2 Place one hand under the lordosis of the patient's lumbar spine Now the patient uses both arms to pull the
sound leg as close as possible to the body until the spine is pressing on your hand This fixates the pelvis in
the normal position
3 Determine the hip flexion contracture on the affected side The hip flexion contracture corresponds to the
angle between the thigh and the horizontal plane If the patient is able to fully extend the hip of the affected
side, there is no hip flexion contracture Enter the value of flexion contracture in X-Soft under "Residual limb
/ Hip flexor contracture"
Determining a socket reference point:
1 Mark the centre of the distal part of the socket in the sagittal plane
2 Mark the proximal centre in the sagittal plane
3 Connect the two points with a line and extend it to the lowest point of the socket
4 Establish the tuberosity and define the socket reference point 30 mm above the tuberosity on the connecting
line drawn before
