Ehh we didn’t do all this core stability in my day!

- Did we need to?
- Normal functioning human beings should be stable beings!
Trunk Stability
- There is more to stability than the core
- Core stability needs to be addressed as part of trunk stability
- Core stability
- Pelvic stability
- Shoulder stability
Muscle imbalance / inhibition causes
- Pain
- Pregnancy
- C – Section
- Obesity
- Inactivity
- Incorrect posture
- Surgery
- Incorrect technique
- Muscle imbalance
Muscle balance
- Muscles should work together and in the right recruitment pattern
Good foundations are essential! - Build the foundation then add on the cosmetic effects.
Abdominals
- Transversus abdominis
- Active in all directions of trunk movement (Zetterberg et al 1987).
- Muscle most consistently related to changes in IAP (Cresswell et al 1992)
- Action precedes that of other abdominals (Cresswell et al 1994)
- Anticipates predictable load to brace before load taken (Hodges and Richardson
1996)
Visceral comp / ‘expulsive acts’.
Thorocolumbar fascia (TLF)
Cross
section
From behind
Thorocolumbar fascia (TLF)
TLF mechanism
- Deep and superficial
lamina form a ‘V’ - Pull of muscles draws spinous processes together
- Provides
resistance to flexion
Hydraulic amplifier
- ES enveloped by posterior layer of
TLF - Muscle expansion restricted leading to fascial tension
- Stress generated
by ES increased by 30% (Hukins et al 1990. Clin Biomech 5, 30-34) - Gluteus max
transmits force through back extensors in lifting spine back to upright position - Muscles attaching into TLF
- Cross section of trunk
SIJ Stability – Posterior
sling
- Hip hinge
- Lifting progressions
- Squat / deadlift / monkey squat
- One legged
squats - Heel strike with opp arm lift
- Lunges with opp arm lifts
SIJ Stability
– Anterior sling
- Exercise
- Single leg standing / kneeling
- Hip hitching
- Hip abduction
progressions - All fours opp arm to leg and out to side
Stretch Weakness
- Muscles
can lengthen over an extended period of time can become lax - These muscle make
adaptations by developing more sarcomeres - Muscles exercised after being lengthened
over a period of time may become firmer but will be in a lengthened position
therefore less ‘strong’ or stable - This can affect posture and muscle balance
in the long term - Correct muscle balance and then correct movement patterns
take time!
