Q

How do you perform Thomas’ test, and what does it assess?

Ask pt to lie down, and to bring their knee up to their chest to ‘hug’ it
Positive test = other leg lifts off bed
Tests for fixed flexion deformities eg iliopsoas tightness, ACL tear, osteoarthritis…

Q

Get pt to lie down, flex hips to 45 degrees and knees to 90 degrees
Test is positive when knees are a different heights
If lower knee displaced towards foot = shortened tibia, if displaced towards body = shortened femur
