Muscle Balance And Exercise Flashcards
Explain the response to hypo and hyper mobility in the body?
Hypomobility results in compensatory hypermobility elsewhere
Hypermolbility results in compensatory hypomobility elsewhere
Postural imbalance may progress to what and give a definition?
Postural decompensation
Distribution of body mass that is away from ideal or not optimal. Essentially, the compensatory mechanisms of the body to maintain good posture are overwhelmed.
What would be an injury/condition of the coronal, horizontal, or Sagittal planes if they were overwhelmed by decompensation?
Scoliosis
Rotations
Kyphosis or lordosis changes
7 risk factors for muscle imbalance or postural decompensation?
Gravity, congenital, altered proprioceptive capability, stress, hormonal imbalance, nutritions suck, or age
What happens to spinal curves due to gravity?
Increase
2 things to remember about repetitive positioning and tasks?
Worsen the effects of gravitational strain
Depending on the activity, the strain can be preferential for a certain part of the body
3 thing sot remember about aging and its effect on postural imbalance?
Altered response to healing
Altered response to gravity
Altered response to injury
What is going on with chronic postural strain?
Over time, as the body adapts and remodels because of strain, structures change their place and form to accommodate the strain and its permanent in a sense.
4 biomechanical effects of gravitational strain?
Curves get worse
Stress on postural tissue
Reflex muscle imbalance
Reduced diaphragmatic functions
What is sherringtons law again?
When a muscle gets an impulse to contract, its antagonist gets an impulse at the same time to relax
3 features of SD in postural muscles?
3 features of SD in movement/dynamic muscles?
Facilitation, hypertonic, and shortened
Inhibition, hypotonic, and weakness
What is the compensatory pattern in 80% and 20% of healthy people?
LRLR
RLRL
3 areas of the body involved in lower crossed syndrome and what 4 biomechanical changed do we find?
Hip, pelvis, and LB
Weak abs, tight iliopsoas, inhibited glutei, and tight erector spinae
5 signs/symptoms of lower crossed syndrome?
Increased sacral flexion
Increased lumbar lordosis
Increased flexion of hip and knees
Hypermobility in saggital and coronal planes at l4-l5 and l5-s1
Sitting up from supine and forward bending dysfunctional
Mnemonic for hypertonic muscles of lower crossed syndrome and what are the individual muscles?
GRHASQTIP
Gastroc, rectus femoris, hamstrings, adductors, soleus, quadratus lumborum, TFL, iliopsoas, and piriformis
What 5 muscles/muscle groups are hypotonic during lower crossed syndrome?
Glutes, vastus medalis, Anterior tibial, peroneals, abs
5 common diagnoses related to lower crossed syndrome?
Chronic LBP SI pain Osteoarthritis in L spine Spondylolithesis Osteoarthritis in hips and knees
What is the neuro: pseudoparesis test for lower crossed syndrome?
Have the patient lay on their back and flex one hip to about 12 inches, then the other and communicate any difference in one side feeling heavier or being more difficult to raise.
Difference between form closure and force closure?
How a joint fits together because of shape and form
The force that keeps it together because of muscles, tendons and ligaments.
Explain the pseduoparesis test of SI joint with joint stabilization both with and without LE extension?
First, repeat the test but stabilize the SI joint with medial compression at the iliac crests, halfway between crests and greater trochanter, and at the greater trochanter
Also, do this with patient prone and extension of the leg instead of flexing.
Explain the interpretation of pseduoparesis perception test?
If everything is balanced, there shouldn’t be any, but if anything is unbalanced, external stabilization is required to get rid of the symptoms.
What structures will get better if there is imbalance when there is external stabilization to the iliac crest? 5 of them.
Same question for midway between crests and greater trochanter?4?
Same for greater trochanter?
Multifidus, lats, levator scapula, lumbar vertebrae, LS junction
Glutes, SI joint, sacrum and innominate
Pelvic diaphragm, hamstrings and structures below the PD
What is the firing pattern for LE extension muscle balance?
Ipsilateral hamstring, ipsilateral glute max, contralteral erector spinae, and ipsilateral erector spinae
What is the correct firing patter for LE abduction muscle balance?
All ipsilateral Glute medius TFL QL Erector spinae
