Differential Diagnoses
OA of the Left Hip
As diagnosed by a GP from X-Ray
Current clinical practice guidelines recommendexercise to treat OA(Thomas, & Kravitz, 2014).
SIJ Sprain due to Chronic Poor Gait Pattern
Subjects with sacroiliac joint dysfunction had significantly more external hip rotation on the side ofthe posterior innominate bone(Cibulka, Sinacore, Cromer, & Delitto, 1998; as cited in Knutson, 2004).
Trauma is suspected as the cause of sprain of the SIJ ligaments(Fortin, 1993; as cited in Knutson, 2004).

Differential Diagnoses
Iliopsoas Syndrome
Conditions involving the iliopsoas muscle include: LBP, sacroiliac pain, disc trauma, hip pain, pelvic
tilt, leg length discrepancies, kyphosis and lumbar lordosis(Morling, 2009).
DJD of the Lower Lumbar
Lumbar degenerative disease present with modification of the sagittal balance, loss of lumbar
lordosis, and increase of pelvis tilt(Barrey, 2004; as cited in Barrey, Roussouly, Le Huec, DAcunzi, & Perrin, 2013).

Working Diagnosis
Left SIJ Sprain due to abnormal gait pattern from severely reduced Right Ankle
Motion and poorly compensating postural musculature, exacerbated by OA of the LeftHip

PSOASLet us be clear about this: the legs do not originate movement in the walk of a balanced body; the legs support an
Movement is initiated in the trunk and transmitted to the legs through the medium of the (ilio)psoas. Ida

The Psoas not Iliopsoas
The Psoas differs from the Iliacus(Sajko, & Stuber, 2009).
Different Architecture
Different Innervation
Different Function
Psoas is comprised of both Major and Minor
Psoas minor is often absent
Psoas minor is present in roughly 40% of the population(Biel, 1997)

Psoas Major Anatomy
Fibrous attachment to lumbar transverse processes
Attachment to anteromedial aspect of all lumbar disc except for L5/S1 disc
Shares common insertion with iliacus muscle
Inserts on the lesser trochanter of the femur
Not a sausage but an elegantly formed muscle
Separate fibres cascade in an almost open spring arrangement from origin to insertion(Morling, 2009)

Psoas Connections
Diaphragm
The psoas is closely connected to respiration process
Major and minor connect to the central tendon
Pelvic Floor
Psoas major in particular forms a link between the diaphragm and the pelvic floor
Possible role in stabilising the lumbar spine during certain phases of the respiratorycycle.(Richardson, Jull, Hides & Hodges, 1999; as cited in Morling, 2009)

Psoas Actions
The primary role of the Psoas
Lumbar Stability or Hip Flexion? Most therapists consider it to be the main hip flexor
Iliopsoas flexes and laterally rotates the thigh(Morling, 2009)
Biomechanical Analysis(Bogduk, Pearcy, & Hadfield, 1992; as cited in Morling, 2009))
Feeble action on Lumbar Flexion or Extension
Axial Compression stabilises the Lumbar Spine
Pulling Femur into the Acetabulum

Psoas States
Contracted Psoas
Due to Postural Habits A deteriorated iliopsoaschronically flexes the body at the level of the inguinal region, so that it prevents atruly erect posture (Rolf, 1989).
When shortened can pull on the spine and/or pelvis to our dominant side
Spasms of Back Muscles resisting the iliopsoas can cause scoliosis, kyphosis and lordosis

The Psoas Effect
Chronic Psoas Spasm (Chila, 2011. p 1014)
Create persistent strain across Lumbosacral Junction Impede resolution of Lumbosacral Somatic Dysfunction in spite of OMT and Exercise directed at L-SRegion
L1 or L2 vertebrae is Flexed and Rotated to the side of the Hypertonic Psoas Muscle

The Psoas Effect
The Psoas Paradox(Agnew, n.d; as cited in Morling, 2009)
The Lumbar Spine hyper extends as the Hip is flexed
Disc Degeneration
Attachment site of the psoas pulls the discs on activation
Causes dysfunctional vector forces on the Lumber Spine when psoas is shortened
Destabilization
Hip and Back at distal and proximal Psoas connections

Not Just a Muscle
The Instinctive Fear Reflex(Koch, 2005)
Can cause a frozen psoas Psoas is responsible for the foetal position
The Reactive Response(Koch, 2005)
Overt emotional and/or strong physical reactions
Fear associated with unresolved trauma

Psoas Assessment
Psoas Syndrome(Chila, 2011. p 572)
Patient walks flexed forward and listing to one side Restricted hip extension
Psoas Dysfunction(Chila, 2011. p 594)
Leg Extension restricted
Foot tend to be Everted
Referred tenderpoint
1cm medial and just inferior to inferior ASIS

Psoas Assessment
Assessment 1:
Client supineActive raise and hold both legs 30cm off the table
Client sit up to 45 against resistance
+ve with moderate pain in the inguinal region
-

Psoas Assessment
Assessment 2:
Client supine Hands together with palms touching above their head
+ve when one palm lower than the other
+ve when body flexed to one side
Can pull the spine into lateral flexion

Psoas Assessment
Assessment 3:
Thomas Test The thigh being held to the chest should be at approx. 45
+ve if extended thigh, viewed laterally, is horizontal or above

Psoas Treatment(Chila, 2011, p 572)
Psoas Syndrome
Key to treat flexed upper lumbar component Treating the psoas
Muscle energy, Still technique, Counterstrain, direct stretching
Home exercises to stretch psoas
Note
Underlying disc protrusion causing spasm
Underlying visceral issue causing psoas hypertonicity
