Thomas Test During the Thomas test, the patient is lying supine (Face up) on the table, the examiner is standing besides the patient. The examiner places one hand between the Lumbar lordotic curve and the table top. One leg is passively flexed to the patient’s chest, allowing the knee to flex during the movement. The opposite leg which is the one being tested rest flat on the table. If the test is positive for hip flexor tightness, the involved leg rises off the table. The structures being implicated in the test are the Iliopsoas muscles, and tightness of the rectus femoris (Starkey & Brown, 2015). Another modification that can be applied to this test is to measure the hip position goniometrically or the patient can passively flex the hip …show more content…

They are some of the strongest muscles on the body. The Iliopsoas muscle which consist of the Psoas major, minor (Not everyone has one), and Illiacus. There is also the quadriceps but more importantly the Rectus Femoris. The Tensor Fasciae Late, Sartorius, and the pectineus also assist in hip flexion. The normal range of motion for hip flexion is 130 to 135 degrees but this can be affected by hip flexor tightness. If a patients suffers from hip flexors tightness there can be many other areas, such as their gait that could become abnormal, arthrogenic gait (stiff hip or knee gait) which can be the result of lost of flexibility at the hip. This can affect their daily living by causing back pains and limiting …show more content…

But they are also less comfortable to the patient because they might not be able to performed this test without pain. They are also more likely to perform it wrong if not properly instructed (Anderson, 2007). The modified Thomas test is a little more difficult to applied because the patient has to be supine while sitting by the edge of the table then bring the leg to his chest while trying to lay down. While the regular Thomas the patient is supine and then actively bring his knees to their chest. but according to (Anderson, 2007, p. 19)”The results show that the Thomas test demonstrated poor statistical reliability for intra and inter-rater comparisons among examiners”. They are saying that the results will vary depending how the examiner interpretates
