Muscle and gait Flashcards
Isometric
Static/tonic
2 types of isotonic contraction
Concentric
eccentric lengthening controlled, in gait allow controlled deceleration, shock absorption , shock absorption, elasticity
Fixed resistance
Isokenetic
Equal force
Tibialis anterior in gait
Eccentric in controlled plantar Flexion to avoid foot slap and heel strike to foot flat
Concentric to avoid toe catch starting swing
Hip extension starting at heel strike
Has to pull the knee back because of closed kinetic chain.
What does Iliopsoas do at initial contact, loading response, mid stance, and terminal swing?
Inactive
What does iliopsoas do at terminal stance, pre-swing, initial swing, mid swing?
Concentric contraction
What does gluteus maximus do at initial contact?
Eccentric contraction
What does gluteus maximus do at loading response, mid stance, terminal stance, pre-swing, initial swing, mid stance, and terminal swing?
It is in active and just looks good.
What does gluteus medius do at initial contact, loading response, mid stance, and terminal stance?
Eccentric contraction stabilizing the pelvis
What does gluteus medius do at pre-swing, initial swing, mid swing, and terminal swing?
It is in active
What do the hamstrings do at initial contact, loading response, initial swing, mid swing, and terminal swing?
Eccentric contraction
What did the hamstrings do at mid stance, terminal stance, and pre-swing?
They are inactive
What did the quadriceps due in initial contact, loading response, pre-swing and initial swing?
Eccentric contraction
What do the quadriceps do in mid stance, terminal stance, mid swing, and terminal swing?
They are inactive
