Goniometry: Hip Flexion
Introduction[edit|edit source]
Thehipjoint'srange of motion(ROM) is an important clinical parameter used inhip assessment.[1]Hip flexion is one of the hip motions that can be measured with agoniometer. The goniometer can simply measure the joint angles. It has some limitations not allowing the clinician to analyse the ROM and track the hip joint during egwalkingor maximum squat. Motion capture devices are mainly used to analyse the patient'sgaitand assess the condition of the joints and bones.[1]

Procedure[edit|edit source]
Client lyingsupine.
Obliterate lumbar curve by flexing other hip and holding.
Flex臀部下的手lumbararea to check no pelvic movement occurs.
- Motions of the pelvis on the lumbar spine during measurement of hip flexion or extension can artificially inflate the range of motion measurement obtained.
- Uselandmarks on the pelvisto eliminate the possibility of including lumbar spine motion in the measurement, or one should manually ensure that thepelvisremains in a neutral position at the beginning and end of the range of motion measurement.
Hip flexion range of motion is dependent on the position of thekneeduring movement.
- Full hip flexion is obtained only with the knee flexed.
- If the hip is flexed with the knee extended, tension in the hamstring muscles limits the motion

Goniometer Placement[edit|edit source]
| AXIS LOCATION | STATIONARY ARM | MOVEMENT ARM |
|---|---|---|
| femoral greater trochanter | parallel to the trunk | parallel with longitudinal axis of the femur in line with the lateral femoral condyle |
Expected Findings[edit|edit source]
Expected range of motion is 0- 120 degrees[3]
Most of the motions at the hip are limited by theligaments(iliofemoral, ischiofemoral, and pubofemoral) andmusclesthat surround the joint, as well as by the hip joint capsule. Hip flexion is an exemption, being frequently limited by approximation of the soft tissue between the anterior thigh and the abdomen when the knee is flexed[2].
