Effect of CROW 3d Printed Sole on Charcot Foot Ulcer
Effect Of Charcot Restraint Orthotic Walker Three-Dimensional Printed Sole On Charcot Foot Ulcer
Study Overview

Conditions
Detailed Description
Foot ulcerations, Charcot neuroarthropathy, and peripheral arterial disease frequently result in gangrene and lower limb amputation. Consequently, foot disorders are leading causes of hospitalization for persons with peripheral neuropathy. Although not all foot complications can be prevented, dramatic reductions in frequency have been achieved by taking a multidisciplinary approach to patient management, The reduction of pressure to the Charcot foot ulcer is essential to treatment. Proper off-loading and pressure reduction prevents further trauma and promotes healing. This is particularly important in the peripheral neuropathy patient with decreased or absent sensation in the lower extremities. Furthermore, recent studies provide evidence that minor trauma (eg, repetitive stress, shoe pressure) plays a major role in the causal pathway to ulceration.
- Off-loading approaches that deal with Charcot neuroarthropathy will decrease the significant psychological, social and functional impact on individuals.
- The need of this study is developed from the lack of controlled studies that reported the therapeutic effect of Charcot Restraint Orthotic Walker 3d printed sole on Charcot foot ulcer.
- So the present study is designed to evaluate the Charcot Restraint Orthotic Walker 3d printed sole on Charcot foot ulcer. Furthermore, the current study may help physical therapist, physicians, and clinicians to organize a protocol of treatment that would be safe, simple and economic for treating patients with Charcot neuroarthropathy.

Intervention / Treatment |
---|---|
ACTIVE_COMPARATOR: Charcot Restraint Orthotic Walker 3d printed sole
the group fit with Charcot Restraint Orthotic Walker 3d printed sole for 12 week.
the protocol of gait analysis testing starts with a reacclimation period during which the subject walked usual freely walking across the path for a duration of four minutes and then the testing session data collection done by four acceptable force platform strikes for the feet fitted with the CROW.

The Charcot Restraint Orthotic Walker (CROW) consists of anterior and posterior shells creating a total contact environment based on a rocker sole. the sole is manufactured by 3d printed Metamaterial . Manufacture of the 3d printed sole of the CROW paths through two stages ;Computer aided designing (CAD) and computer aided manufacturing (CAM) . |
ACTIVE_COMPARATOR: Generic Charcot Restraint orthotic walker
the group fit with Generic Charcot Restraint Orthotic Walker for 12 week.the
protocol of gait analysis testing starts with a reacclimation period during which the subject walked usual freely walking across the path for a duration of four minutes and then the testing session data collection done by four acceptable force platform strikes for the feet fitted with the CROW.
|
It is a clamshell (two piece) design that provides complete/total contact over the shin, calf and foot.
The CROW reduces all motion in the ankle and foot to reduce potential for further injury.
It is fully padded on the inside, and the bottom is covered with a material similar to shoe soling.
It is not worn with a shoe.

Measure Description |
Time Frame |
---|---|---|
Force platform to measure peak vertical ground reaction plantar force
Time Frame: Pre-intervention
|
Plantar vertical ground reaction force obtained at a rate of 100 Hz measured by Nintendo Wii Balance Board (WBB Nintendo Co. Ltd.
Kyoto, Japan) through a four strain gauge sensors (uniaxial vertical force transducers) located at the corners of the board with a usable size of 45 x 26.5 cm were used for data collection; wirelessly via Bluetooth by using third party software illustrates the peak vertical force parameter.

Measure Description |
Time Frame |
---|---|---|
Wound Surface area using ImageJ software
Time Frame: Pre-intervention
|
The patient is positioned in a comfortable position with exposure of the wound.
A ruler as a reference is place directly flat and attach to the skin around the wound area.
A photographs were taken including the reference ruler in the images that is captured for the whole wound margins taking in consideration standardization the same angle of capture in the flat mid foot ulcers, but in case of ulcers extend to foot edge, a sterilized transparent grid film (1x1 cm) attached flat on the ulcer then wound margins traced on the transparent grid film and then photographed, then the captured photographs is exported to the computer to be visualized with ImageJ 1.52t software.
Surface area measurement of wound margins are traced by the same investigator to establish reliability of measurements
