Functional Pelvis Flashcards
Know the location of the peak vertical force in the equine back when movement at the LS junction and the coxofemoral joint are taken into account
Lumbosacral junction
Know the clinical signs of SI joint dysfunction (11)
- Poor performance
- Unwillingness to engage the hindquarters
- Kicking
- Bucking under saddle especially at canter
- Offers canter instead of trot on the lounge line
- Four beat canter
- Changing leads behind
- Uneven gait in lateral work
- Reluctance to change leads
- Reluctant to engage hindlimb and also to fully extend the hindlimb
- Carries hindquarters to the inside on the lounge line
Know the signs of SI joint dysfunction found on physical exam (6)
- Atrophy of the gluteals muscles
- Atrophy just lateral to the tuber sacrale
- Pain on ventral pressure over the SI joint
- Dragging toes behind
- Hindlimbs have a short cranial and caudal phase of stride
- Back held stiffly and is not involved in the movement
Know the likely explanation for the muscle atrophy seen with SI joint problems
SI dysfunction affecting the lower motor neurons to the gluteal muscles
Know the most common complaint from the owner of a horse with sciatic pain or dysfunction and why this sign is seen. What two other signs are seen?
“Drops out behind”
Extensor weakness
Kicking at stall with one hind leg (pain worse with rest)(Qi def)
Know that distal limb pain that is unresponsive to treatment may be _______
sciatic neuralgia.
Which lateral bend is inhibited with a right PI ilium?
Left
Know how a pelvic or sacral restriction can affect the psoas muscle
Pelvic AS
How does a pelvic or sacral restriction affect the sacrosciatic ligament and how can you treat the ligament?
Affects structures in the greater and lesser sciatic foramina and associated muscles
Describe Logan basic procedure
Pressure where tail meets the body, gentle pressure on caudal edge of sacrosciatic ligament to release tension
