Overall Instability and SI joint

Question 1

Excessive movements of the spine that are within the active subsystem (muscular) control. For example, a gymnast has increased mobility but also has the strength and coordination to control the mobility. There are no aberrant movements present

Answer 1

hypermobility

Question 2

sxs or components that provide stability to the spine

Answer 2

1. Passive subsystem – the spinal column and its ligamentous support
2. Active subsystem – the muscles and the fascial systems
3. Control subsystem – neural system of balance, coordination, timing, firing

Question 3

diff btwn hypermobile and instable

Answer 3

hypermobile they can still control

instable, there is uncontrolable laxity or abberant mvmt

Question 4

The zone where there is minimal resistance to motion of a given vertebra

Answer 4

neutral zone

Question 5

function of ligg

Answer 5

provide the most support to the spine at the end ranges of motion where they check excessive mobility

if there are deficits to the subsxs then what occurs

Answer 6

increased mobility

Question 22

what is the principal action of the multifidus

principal action of the multifidus is segmental control

also prevents forward bending force as abs rotate trunk
