Walking and Gait Flashcards
1
Q
what is locomotion?
A
ability to move from one place to another
2
Q
what are the two phases of the repeated gait cycle?
A
stance - 60% of gait
swing - 40% of gait
3
Q
what stages are in the ‘stance’ phase of the repeated gait cycle?
A
heel-strike
support
toe off
4
Q
what stages are in the ‘swing’ phase of the repeated gait cycle?
A
leg lift
swing
5
Q
what 3 muscle are involved in the heel-strike stage of the RGC? what is the role of each?
A
- g.maximus - decelerates forward motion via hip joint
- quadriceps femoris - maintains extension at knee and flexion of thigh
- anterior compartment of leg - maintains ankle dorsiflexion
6
Q
what 3 muscle are involved in the support stage of the RGC? what is the role of each?
A
- quadriceps femoris - stabilises knee in extension
- foot inverters + evertors - contract to stabilise foot
- g.minimus, g.medius, tensor fasica lata - abduct lower limb
7
Q
what 3 muscle are involved in the toe off stage of the RGC? what is the role of each?
A
- hamstring - extends thigh at hip
- quadriceps femoris - maintains knee extension
- posterior leg compartment - plantar flexes ankle
8
Q
what 3 muscle are involved in the leg lift stage of the RGC? what is the role of each?
A
- ilipsoas and rectus femoris - maintains hip flexion + resists gravity
- quadriceps femoris - knee extension + positions foot for landing
- anterior leg compartment - maintains ankle dorsiflexion
