Lower Limb Flashcards
General Characteristics of Lower Limb?
Longer
More 1Dimensional action
More robust and stable
Less range of joint movement
Attachments of the iliotibial tract?
iliac crest tubercle
lateral condyle of tibia
Location of Antigravity muscles
Hip: Posterior Thigh Muscles
Knee: Quadriceps Femoris
Ankle: Posterior Leg Muscles
Location of axis of centre of gravity
Anterior to Sacral vertebra 2
Behind Hip Joint
Anterior to Knee and Ankle Joints
Hip Joint Extension and ankle joint plantar flexion are both what type of movements?
Power Movements (2)
Repositioning movements (2 in Swing)
hip joint flexion in swing and knee joint extension in late swing.
What are repositioning movements?
Movements that place the limb in a position where power movements can be applied/more effectively.
What are power movements?
Applying thrust to the body and propelling it forward
What are compensation movements?
Maintain balance or correct for previous movements
Examples of compensation movements are?
Hip joint abduction by gluteus medius and minimus in early stance
Ankle joint dorsiflexion by the anterior leg muscles in mid swing
Example of a braking action
Action of the posterior thigh muscles in late swing when they slow and stop the action of the hip joint flexors
3 ways muscles generate force?
Isotonic contraction
Isometric contraction
Eccentric contraction
If force accumulates down the body at which two points is halved
Hip Joints
Between calcaneus and heads of metatarsals
