Myokinematic Functional Relationships
+ L Add = + L Ext
+ L Add = - L Ext (iliofemoral / pubefemoral laxiety)
+ L Add = Limited R TR
+ L Add = Non-Limited R TR (Right iliolumbar laxiety)
+ L O = Decreased L Leg Length
+ L O = Increased L Leg Length (Iliofemoral / pubefemoral laxiety, anterior capsule hypermobility or posterior capsule hypomobility; usually associated with increased Left FA IR)
+ L Add = Decreased L SLR [Proximal attachment site of hamstring group is more forward and elevated secondary to anterior rotation of innominate]
+ L Add = Increased L SLR (Long, neuromuscularly weak, hypotonic, overly stretched “inactive” hamstring group)
+ L Add = Decreased L IR (Overactive Left TFL, Left FA ER’s and restrictive/tight posterior capsule secondary to Left AF ER osseous position)
+ L Add = Decreased R ER (Overactive Right adductors, Right FA IR’s and impingement of femoral head on anterior superior and medial acetabular cotyloid rim upon FA ER secondary to Right AF IR osseous position)
+ R Add = + L Add [Posterior Exterior Chained patient, PEC]
+ L Ext = + L Add
+ R Ext = + R Add
L AF IR = R AF ER
R AF IR = L AF ER
KEY:
L = Left
R = Right
+ = Positive Test
- = Negative Test
Add = Adduction Drop Test
Ext = Extension Drop Test
TR = Trunk Rotation Test
SLR = Straight Leg Raise
AF = Acetabular Femoral
FA = Femoral Acetabular
IR = Internal Rotation
ER = External Rotation
( ) = Pathocompensatory issue
