Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Clinical study of 20-30 participants who will receive and wear Ankle Foot Orthosis (AFO) manufactured through a digital process. AFO is a brace that is worn on the lower leg and foot to support the ankle, hold the foot and ankle in the correct position and correct foot drop. AFO used in this trial will be manufactured by the use of three-dimensional scanning technology along with the computer-aided design and additive manufacturing technologies (selective laser sintering). AFOs will be personalised to each participants based on the measurements obtained from 3-Dimensional scanning. The participants will be required to wear the AFOs for 6 months and be asked to gradually wear the AFOs as follows: Day 1 - 1 Hour in AM, Day 2 - 1 Hour in AM, 1 Hour in PM, Day 3 - 1.5 Hours in AM, 1.5 Hours in PM, Day 4 - 2 Hours in AM, 2 Hours in PM, Day 5 - 2.5 Hours in AM, 2.5 Hours in PM and Day 6 and After - All Waking Hours.

Unlike traditional AFOs, this investigational product is made of Nylon 12, widely used for medical implants and has been certified as biocompatible.

The study time points are as follows: Screening/Scanning (Up to Day -15), Production (Day -14 to -1), Fitment (Day 0), Face to Face Follow Up at Week 2 and 6 Months, Phone Follow Up at 1 Month, 2 Month, 3 Month, 4 Month, 5 Month.
Intervention code [1] 299479 0
Treatment: Devices
Comparator / control treatment
The 6 months results collected from these patients using digitally manufactured AFOs will be compared against the pre-existing performance and experience data available of the same patient wearing AFOs made using the traditional method previously. AFOs are won as soon as the child is diagnosed with the physical disability.

The traditional AFOs operate the same way as the investigational product but method of manufacturing AFOs are time consuming and are made of thermoplastics comprised of polypropylene and polyethylene. The data will be collected prospectively using experience interviews with the parent's of the participants and the investigators comparing their experience of digitally manufactured AFOs to the traditional AFOs that the participants were wearing. This data will be collected prospectively for purposes of data collection.

Outcomes
Primary outcome [1] 303778 0
To explore whether AFOs manufactured through digital fabrication technology are a biomechanically viable alternative to traditionally manufactured AFOs for children aged 2-8 years with physical disabilities. This is assessed by ISPO Assessments (Gait Analysis) and phone experience interview..
Timepoint [1] 303778 0
Fitment (Day 0), Face to Face Follow Up at Week 2 and 6 Months (Primary Endpoint), 1 Month, 2 Month, 3 Month, 4 Month, 5 Month Phone Follow Up
Secondary outcome [1] 340121 0
To evaluate if 3D printed AFOs are equally as robust as traditionally manufactured AFOs when all materials undergo comparative mechanical testing. This outcome is measured by customised testing rig named Tara and comparing the robustness when bent 45 degrees at the ankle 500 degrees.
Timepoint [1] 340121 0
Production (Day -14 to -1),
Secondary outcome [2] 340122 0
The distress experienced by participants and their families when being measured for an AFO assessed by experience interviews when compared to traditional plaster casting methods. The distress levels are assessed by the experience interviews during the screening and scanning stages where they are asked if distress levels when being measured for a new AFO are lower or higher compared to the time when traditional plaster measurements were performed.
Timepoint [2] 340122 0
Screening/Scanning (Up to Day -15)
Secondary outcome [3] 340123 0
The orthotists experience with the new digital method assessed by experience questionnaire specifically designed for the trial for Orthotists compared with the traditional manufacturing method.
Timepoint [3] 340123 0
Screening/Scanning (Up to Day -15), Production (Day -14 )
