Normal ROM for knee flexion?
130–150°
Normal ROM for knee extension?
0° (0–15° hyperextension not uncommon)
Goniometer axis for knee flexion/extension?
Lateral epicondyle of femur
Goniometer stationary arm for knee ROM?
Lateral midline of femur, toward greater trochanter
Goniometer mobile arm for knee ROM?
Lateral midline of fibula, toward lateral malleolus
Patient position for knee flexion/extension ROM?
Supine with knees extended, hip in neutral; towel under heel for extension
How do you cue AROM knee extension?
Ask patient to ‘push the back of your knee toward the table’
How do you apply PROM force for knee extension?
Force applied anteriorly just proximal and just distal to the knee joint
Zero Neutral documentation if patient achieves full knee extension?
Flexion 0–130°; Hyperextension 0–4°
Zero Neutral documentation if patient cannot achieve full knee extension (e.g., lacks 12°)?
Flexion 12–130°; Extension lacking 12°
Alternative documentation if patient achieves full extension/hyperextension?
4°–0°–130°
Alternative documentation if patient cannot achieve full extension (e.g., lacks 12°)?
12°–130°
Normal hamstring length by straight leg raise?
70–80° of hip flexion with knee fully extended
Popliteal angle test: patient position?
Supine, ipsilateral hip flexed to 90°, neutral frontal/transverse plane, knee flexed; contralateral hip neutral
Popliteal angle test: what is measured?
The angle lacking from vertical (goniometer axis: lateral epicondyle; stationary: lateral midline of femur; moving: lateral midline of fibula)
Ober Test: purpose?
Assesses TFL/IT band length (knee flexed)
Modified Ober Test: how does it differ?
Knee is extended instead of flexed (tests TFL more purely)
Ober Test: positive finding?
Thigh does not reach horizontal or lower when lowered toward table
Ely’s Test: purpose?
Assesses rectus femoris length
Ely’s Test: patient position?
Prone with knees extended; stabilize posterior pelvis; flex ipsilateral knee
Ely’s Test: normal length finding?
Knee flexion to 90°
Thomas Test: purpose?
Assesses hip flexor (iliopsoas and rectus femoris) muscle length
Thomas Test: patient position?
Seated at end of table, roll supine, flex both hips/knees to chest until lumbar lordosis flattens; therapist extends test thigh toward table
Thomas Test: normal length finding?
≥80° knee flexion with thigh flat on table
