gait analysis

Question 1

what degree is the hip flexed during initial contact?

Answer 1

hip is flexed to 20* and slight ER

Question 2

what muscles are activated during initial contact of gait?

Answer 2

hip glute max/ hamstring to reduce flexion
erector spinae to resist trunk flexion
ankle dorsiflexion

Question 3

what are some potential problems that could affect intital contact

Answer 3

foot slap (L4, dorsiflexion)

excessive trunk extension (glute max) (Lurch gait - ineffective glute max. they will lean backwards during terminal swing/initial contact.)

equinus deformity

plantar flexor spacticity

forward trunk lean - reason for this is for weak quadriceps.
