简要总结
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.
详细描述
A single centre, double blinded, randomised controlled trial. Interventional, equivalence Trial design.
Participants will be asked to attend 2 face-to-face appointments for assessing and fitting of insoles, which is standard practice in the NHS GGC Orthotic Department. Each face-to-face appointment will take approximately 40 minutes. Following the fitting of the insoles, participants will be asked to participate in 3 telephone calls over 12-weeks, during which they will be asked to answer questions from two questionnaires (the "Foot Health Status Questionnaire", and the "Orthotic and Prosthetic User Survey"). Each telephone appointment will take approximately 15 minutes. Once participants receive their insoles, they will also be asked to keep a diary detailing the number of hours that they wore the insoles each day over 12-weeks. This information will be collected by the Orthotist involved with the trial during the telephone review appointments.

结局指标
主要结局
Foot Health Status Questionnaire (FHSQ) - Pain Sub-domain
时间窗: 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.
