FINAL BIOMECHANICS ESSAY Flashcards
Mcneil, 2005?
Footwear biomechanical level, structure, function, motion, mechanical aspects, biological systems
Kleppner, 1973?
Angular kinematics, rotational motion, absence of forces
Angular kinetics, rotational motion, regard to forces
Clinghan, 2008?
Profit, shoe companies
Clarke, 1983?
Motion control shoes, reduction, rear foot motion, ankle inversion injuries, anterior knee pain, plantar fasciitis
Medial posting, dual density
Barret, 1985?
Affects athlete wellbeing
Figures 1?
Figure 1: Rearfoot motion graph, y 5 to -10 rearfoot angle, x time
Upside down bell curve
Average 8-10 degrees
Label maximum
Figure 2?
Right leg going outwards then inwards labelled supination
Label rearfoot angle
Right leg going inwards then outwards
Label rearfoot angle
Figure 3?
4 pieces of bone, top left, top right, middle, bottom
Talocrural joint = top and left of middle bone
Subtalar = bottom of middle bone
Description of figures 1 and 2?
Rearfoot motion
heel stance, = supination, =inversion plantar flexion adduction
Midstance, = pronation, = eversion, dorsi flexion, abduction
Toe off = propulsion
Description of figure 3?
Foot and ankle complex
Subtalar = frontal + transverse movement, dissipation of momentum, hardness for propulsion
Talocrural, dorsiflexion + plantar flexion, hinge joint
Hrelijac (2000)?
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
Luz (2017)?
Patellofemoral pain, kinematic data, 3D system
Greater rearfoot eversion = patellofemoral pain
Changing it can reduce symptoms
Conclusion for main paragraph 1?
Hrejilac (2000), small sample of 20, retrospective, grouped injuries
Luz (2017), more recent, but cross sectional, only kinematic data, rehabilitation rather than prevention
Introduction main point 2?
Prospective better than retrospective
Rice (2013)?
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
