Movers Vs Stabilisers Flashcards
anatomical/position/function ( Stabiliser)
Function:
against gravity
Maintain joint alignment
Joint compression
Anatomy: One joint muscle Multi penmate (diagonal fibres)
anatomical/position/function (mover)
Function: Big joint movement
Position: insert into blown via tendon
Anatomy: riempiespiere
Longitudinal fibres
(6)Physiological composition: stabilising
- Slow twitch (tonic) type 1/red Fiber
- Slow contract time
- Low-frequency
- Low threshold
- Does not to tire easily (aerobic work)
- After and feedback = proprioception
(5) Physiological composition : movers
- Fast twitch (phasic). Type II A and type 2 B. White fibre
- Fast contract time
- High-frequency
- High threshold
- Tires quickly (anaerobic)
Define stabiliser
It is a muscle which primary function is to support body segments
Name 4 primary stabilising muscles
1) Lumber multifidi
2) Transfers abdominus
3) Diaphragm
4) pelvic floor
Responsible for posture
What does a inappropriate act of diaphragm cause
Shape of ripped cage is affected
What does the weakness/ inactivity of multifidi cause
low back pain
What does poor control of pelvic floor cause
Bladder/bowel incontinence
Name and discuss the first interdependent level of stabilisation
1) Control of spinal orientation in relation to maintaining spinal column alignment against external forces. (Global stability)
Name and discuss the second interdependent level of stabilisation
Intersegmental control regardless of changes in orientation of spinal column (local stabiliser)
What is the stability of the spine dependent on
The two levels of interdependence stabilisation
Three examples of local stabilisers
Transfers abdominis
Multifidus
Quadratus Lumborum
4 examples of global stabilisers
Diaphragm
External oblique abDominus
Internal oblique abdominus
Pelvic floor
Summary of function of local stabilisers
1) Muscle stiffness = oppose spinal translation
2) Constant and independent of direction of movement
3) no changes in legth during contraction
4) intersegmental control
