Definition/Description[edit | edit source]
Patient should be lied on his back and must then maximally flex both knees, using both arms. Then he has to lower one limb toward the table. [1][2]
Clinically Relevant Anatomy[edit | edit source]
Iliopsoas muscle group[3]
M.iliopsoas: Main
function → thigh flexion
Additional
feature→external rotation
M. Rectus Femoris: Main
function → thigh flexion
Additional
feature→knee
extension
M. Tensor Fascia Latae: Main function → thigh flexion
Additional
feature→internal rot., abduction
M. Sartorius: Main function → thigh flexion
Additional
feature→knee flexion
Purpose
[edit | edit source]
The Thomas Test or Iliacus Test is used to measure the flexibility of the iliopsoas muscle group, the M. Rectus Femoris, the M. Tensor Fascia Latae and the M. Sartorius are also used in musculoskeletal screening.[4]Measuring the flexibility of this muscle is not useful, because we don’t have a standard meeting length of muscle. The most important aspect of this test is that the range of motion [5] of the hip is measured as the various diseases may shown as patellofemoral pain syndrome [6], lower back pain[7], osteoarthritis and rheumatoid arthritis[8].
Technique[9]
[edit | edit source]
The patient should be positioned in supine, with one knee flexed and being held to the chest at the point when the lumbar spine begins to flex. The therapis assesses the thigh of the opposite leg to determine if it maintains full contact with the treatment surface. If the thigh is raised off the table, this test is considered to be positive.
A modified version of this test, the Modified Thomas Test, is commonly used. The patient is positioned in supine at the very edge of the treatment table. The patient is asked to bring both knees to his/her chest. While in this position, the patient is to perfrom a posterior pelvic tilt. While the contralateral hip is held in maximum flexion the tested limb is lowerd back towards the floor. This test is positive for iliopsoas muscle tightness if the thigh is raised off the table. If the knee extends when an extension force is applied to the hip, then the rectus femoris is considered tight[10].
