2. Project Plan

3. Project Progress - Problem Identification
Injuries
Ankle Joint
Anterior Inferior Tibiofibular Ligament
Achilles Tendon
Comfort/ Support
Weight Distribution
Gait – Phases
Foot Arch

4. Ankle Joint Uniaxial Hinge, No appreciable lateral movement can occur,
Dynamic rotation
Knee bent
Knee straight

5. Anterior Inferior Tibiofibular Ligament
Most ankle fractures are associated with ligament injuries.
Most common injured
ligament
Caused by Pronation
(Rolling ankle)

6. Achilles Tendon Energy Transfer Most important tendon in leg.
Storage and release
Transfer to limbs through muscles
Overheating
Most important tendon in leg.
Capable of stretching
Heel hits Achilles must counter act this action by stretching

7. Weight Distribution 1/3 of all weight taken by first metatarsal
Heel, Ball and outer
foot most affected by
propulsion.
Runners – 80% Heel
strike, 20% mid-
foot strike.

8. Gait - Phases Propulsion Swing and Stance Double Support Phase
Jogging,
Running

9. Foot Arch Make up – Tarsal and Metatarsal Bones.
Stability comes from ligaments (plantar fascia)
Prevents weight being
transferred from tibia
to ground.
Can flatten to 10mm
from ground.

10. Project Progress - Market Rationale/ Target Group

demand.
Proven market.
Tallest Male/ Female
Professional to Smallest
Male/ Female
