Abstract
The purpose:Charcot neuroarthropathy is a chronic and progressive disease bone and joint degradation in limbs that
have lost sensory function can be painful or painless. Synovitis, subluxation, instability and destruction are all figure
of symptoms of affected joints. Trauma is believed to be a key initial element that symptoms exist, features of injury
are foot deformities, bony prominence, and instability result from bonny fragmentation, fissures, and
dislocation.Adapted Charcot restraint orthotic walker with rocker profiles design is one of the most useful shoes that
has been cause the plantar pressure to be decreased. This type of orthosis facilitates “rocking” from heel contact to
toe-off, helping the tibia to roll over the foot more smoothly and reducing both the range of motion of foot joint and
pressure at plantar aspect, the current study is to asses a novel design sole of the CROW and replace the rocker
bottom with a 3D printed metamaterial sole and the current study is to measure the impact of the Charcot
neuroarthropathy subject during gait through peak vertical ground rection force using Nintendo wii force platform.
Subject:sixty participants with Charcot neuroarthropathic foot were randomized in a parallel group trial with
concealed allocation, and assessor blinding. Participants were divided randomly in to two groups, Participants in the
group A (n=30) were fitted with 3D printed metamaterial sole CROW. Participants in the group B (n=30) were fitted
with generic rocker bottom CROW.
Procedure: the participants in both groups walk on the equipped walkway with the Nintendo Wii force platform to
measure peak vertical ground reaction force in Newton. Data collected through four acceptable force platform
strikes by the both study groups.Results: the 3D printed metamaterial sole CROW results showed a decrease in the
vGRF in comparison to generic rocker bottom CROW , There was a significant decrease in the peak vertical ground
reaction force in group A compared with group B treatment (p = 0.00) the statistical significance of (effect size) in
the tests, ŋ2; a measure of effect size was high= 0.75 ≥ 0.50).
Conclusion: Results of the current study revealed decrease in peak vGRF for groups fitted with Charcot
neuroarthropathic patients fitted with 3D printed metamaterial sole CROW in comparison to generic rocker bottom
CROW group. That make a good potential for additive manufacturing in health care sector.

Key words: Charcot neuroarthropathy joint, Peak vertical ground reaction force, 3D printed metamaterial Charcot restraint orthotic walker, Wii force platform
