elbow extension ROM
stationary: acromion
fulcrum: lat epi

elbow pronation ROM
stationary: mid line of humerus
fulcrum: dosal and proximal to ulnar styloid
movement: dorsal surface of wrist
0-80 deg
elbow supination ROM
stationary: midline of humerus
fulcrum: ventral and proximal to ulnar styloid
movement: ventral surface of wrist
0-80 deg
elbow flexion 3-5
seated
resistance into ext
elbow flexion 0-2
seated, arm on table, shoulder 90 deg abd
can they do full ROM?
elbow extension 3-5
supine, shoulder flexed to 90 deg and
resistance into flexion
elbow extension 0-2
seated, arm on table, shoulder 90 deg abd
can they do full ROM?
elbow supination 3-5
seated
push into pronation
elbow supination 0-2
seated, elbow on table, arm vertical
can do full ROM?
elbow pronation 3-5
seated
push into supination
elbow pronation 0-2
seated, elbow on table, arm vertical
can do full ROM?
humeroulnar joint distraction
supine, arms at side
elbow flexed to 90 deg
stabilize at bicep and distal to elbow
distract from joint
humeroradial joint distraction
supine, arms at side
elbow extended
stabilize at bicep and distal to elbow
distract from joint
varus stress test
seated or standing
20-30 deg of flexion
apply varus force (lateral force)
+ causes pain
valgus stress test
seated or standing
20-30 deg of flexion
apply valgus force (medial force)
+ causes pain
chair push up test
seated elbows at 90 deg
pushes down on chair arms
+ reluctance to extend elbows
moving valgus stress test
seated with arm abd to 90 deg, elbow fully flexed
provides valgus stress until fully extended
+ reproduces pain with extension
tinel’s sign at the elbow
seated elbow flexed to 90 deg
taps ulnar nerve 4-6 times
+ reproduction of symptoms along ulnar distribution
