Foot Health Status Questionnaire (FHSQ) - Pain Sub-domain Primary · Measured 4 times throughout the 12-week period that the participant is wearing the insoles: Baseline immediately after receiving intervention (insoles). 4 weeks after intervention. 8 weeks after intervention. And 12 weeks after intervention

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.

Sponsor's own description

The main purpose of this study is to find out if scanning the foot using a 3D scanner influences the effectiveness of custom made insoles, compared to the more traditional approach of taking a foam-box impression cast of the foot. Both of these methods are currently used as standard care in the NHS Greater Glasgow and Clyde (GGC) Orthotic Department. In this study, insoles will be manufactured either from a direct 3D scan of the foot, or from a foam-box impression cast, and a series of questionnaires will be used to measure any changes in foot pain and foot function. The results from this study will be used to develop an information resource for both patients and Orthotists which will fill gaps in our current knowledge and hopefully guide us further in providing the best possible care for future patients who require insoles.
