Flashcards in Muscle Balance Deck (11):
1

Contraction of a muscle involves reciprocal inhibition of the ________ antagonist and ________ agonist.

Ipsilateral, contralateral

2

A chronic facilitated muscle can lead to prolonged ________ of an antagonist and eventually muscle weakness.

Inhibition

3

What are some examples of tonic/postural muscles?

Hamstrings

Iliopsoas

Piriformis

Tensor fascia lata

Rectus femorus

Thigh adductors

4

What are some examples of dynamic/phasic muscles?

Vastus medialis/lateralis

Gluteus minimus

Gluteus medius

Gluteus maxiums

5

What are some theoretical causes of muscle imbalance?

Dysregulation of the CNS

Postural adaptation to gravity

Change in mechanical behavior of joints

Habitual movement patters

Noxious stimuli

Muscle balance responds to physical demands

Psychological influences

6

Who first described upper and lower crossed syndromes?

Vladimir Janda, MD, DSc

7

What is the muscle firing pattern of hip extension?

1) Hamstrings

2) Gluteus Maximus

3) Contralateral lumbar erector spinae

4) Ipsilateral lumbar erector spinae

8

Dysfunctions in hip extension can lead to ________ pelvic tilt, lumbar ________, and a number of other issues.

Anterior, hyperlordosis

9

Lower crossed syndrome involves weak ________ and ________, and tightened ________ and ________.

Abdominals, gluteus maximus, hip flexors, erector spinae

10

Upper crossed syndrome involves weak ________ and ________, and tightened ________ and ________.

Neck flexors, middle/lower trapezius, upper trapezius/levator scapulae, SCM/pectorals

11

How are upper and lower crossed syndrome treated? (In what sequence)

1) Core retraining

2) Stretch and lengthen hypertonic postural muscles

3) Activate and strengthen inhibited dynamic muscles

4) Maintenance (home exercises)
