Trial Outcomes & Findings for Comparing Clinical Outcomes Using Two Insole Manufacture Techniques (NCT NCT05444192)

NCT ID: NCT05444192

Last Updated: 2025-05-23

Results Overview

To compare the changes in pain in two groups of participants fitted with custom CAD/CAM insoles manufactured using different foot shape capture methods. Units on a scale. Minimum score is 0, maximum score is 100. Higher scores represent better outcomes.

Recruitment status

SECONDARY outcome

Timeframe: Costs were calculated per participant from baseline until their completion of the trial at week 12.

A differential cost analysis was undertaken. This involved calculating the total cost for each participant using a calculation of transit costs, staff time, and physical resources for each participant throughout their time in the trial.
