Q

Description of figures 1 and 2?

A

Rearfoot motion

heel stance, = supination, =inversion plantar flexion adduction

Midstance, = pronation, = eversion, dorsi flexion, abduction

Toe off = propulsion

Q

Description of figure 3?

A

Foot and ankle complex

Subtalar = frontal + transverse movement, dissipation of momentum, hardness for propulsion

Talocrural, dorsiflexion + plantar flexion, hinge joint

Q

Hrelijac (2000)?

A

Lower extremity, biomechanical and anthrpometric, kinetic + kinematic, force plate, 4m.s^-1, filming

Looked at people with overuse injuries and no injuries

Found lower velocity in pronation in overuse injuries

= motion control detrimental

Q

Luz (2017)?

A

Patellofemoral pain, kinematic data, 3D system

Greater rearfoot eversion = patellofemoral pain

Changing it can reduce symptoms

Q

Conclusion for main paragraph 1?

A

Hrejilac (2000), small sample of 20, retrospective, grouped injuries

Luz (2017), more recent, but cross sectional, only kinematic data, rehabilitation rather than prevention

Q

Rice (2013)?

A

Ankle inversion risk, 145 injury free male recruits

Plantar pressure, kinematic variables

No association, peak eversion or eversion range

Was associated with narrower bimalleolar breadth width

Q

Willems 2005?

A

223 PE students, lower leg alignment + 3D kinematics and plantar pressure obtained

6-18 months after injuries collected

Injury = maximum tome in pronation, so footwear is beneficial

17
Q

Mini conclusion for main paragraph 2?

A

Both studies valid large and prospective

Talk about individualism
