Thomas test of hip flexor and knee extensor tightness
Thomas test of hip flexor and knee extensor tightness
The Thomas Test is used to assess tightness in the hip flexors and knee extensors. If the hip flexors are tight, the thigh of the dangling extremity inclines toward the ceiling; if the knee extensors are tight, the dangling leg inclines away from the examining table. The patient in the photograph demonstrates tight knee extensors and hip flexors.
