Tests Flashcards
Know which tests test what
Knee flexion supine angle
140-150 degrees
Knee flexion prone angle
135 degrees (rectus femoris limiting)
Knee extension angle
prone; minus 2 degrees, plus or minus 3 degrees
Medial/lateral knee rotation
legs off bed; stabilise femur and externally/internally rotate tibia
Testing knee extension
legs off bed; resist them extending; ask to “kick leg out”
Testing knee flexion
prone; stabilise femur; ask pt to flex whilst providing extension force on achilles
Testing knee flexion without gravity
Pt on side; hold upper leg abducted; stabilise femur; ask pt to flex lower leg
Patellar mobility test
Testing: passive glide of patella ROM
Detects: tightness of vastus lateralis and medialis
Performed: supine; knees 20-30 degrees flexed; quads relaxed (pillow under knees if necessary); move patella up down left right
Clark’s sign
push down and inferior on patella; ask pt to contract quads
positive: pain with movement of patella or inability to complete test
Patellar tracking test
legs off bed; actively extend knee from 90 degrees
normal = straight movement with slight lateral shift near full extension
abnormal = sudden lateral movement at full extendion; inverted J shape path
Apprehension test
determine previous history of lateral dislocation/subluxation
gently push patella laterally
positive: pt feels like patella will laterally dislocate
Anterior drawer test (knee)
testing: ACL integrity
injury: blow to hyperextended knee or twisting, non-contact injury
pt supine; hip and knee flexed; feet flat (sit on pt foot); anterior force to tibia
positive = soft end feel/excessive anterior movement of tibia
Slocum test
knee anterior drawer test
Lachman test
anterior drawer test with knee in 15 degrees flexion and external hip rotation (foot planted)
posterior drawer test
anterior drawer test but push instead of pull
Valgus (abduction) stress test
pt supine; knee slightly flexed
push knee in, pull ankle out
medial opening of joint = medial instability of ligament
pain = acute injury
varus (adduction) stress test
pt supine; knee slightly flexed
pull knee out, push ankle out
lateral opening of joint = lateral instability of ligament
uncommon injury (mostly sport related)
McMurry’s test
knee meniscal tears
1) leg externally rotated, varus (outward) stress to test MEDIAL MENISCUS
2) leg internally rotated, valgus (inward) stress to test LATERAL MENISCUS
Knee extension lag
also called quadriceps lag
often of functional relevance in knee rehab
inability to actively move joint to its passive limit
pt supine; knees hanging off bed; flex one knee up and leg other leg hang; passively extend extended knee, then ask pt to do it actively
if can’t complete, is positive
femoral pulse location
midway between pubic tubercles and anterior superior iliac spine
Anterior internal rotators
Iliopsoas
Posterior internal rotators
g. medius
g. minimus
adductors
Anterior external rotators
sartorius
deep anterior fibres
posterior external rotators
g. maximus
piriformis
deep posterior fibres
<45 degrees motion internal rotation with hip extended
Tight anterior external rotators - sartorius and deep anterior fibres
<45 degrees motion internal rotation with hip flexed
Tight posterior external rotators - g. maximus, piriformis and deep posterior fibres
<45 degrees motion external rotatation with hip extended
Tight anterior internal rotators - iliopsoas
<45 degrees motion external rotation with hip flexed
Tight posterior internal rotators - g. medius, g. minimus, adductors
Thomas test
Testing: hip flexion contracture and psoas syndrome
Hip flexion contracture associated with what kind of people?
runners, dancers and gymnasts
Thomas test - knee higher than hip
tight psoas
