Nutritional, Metabolic, Endocrine: Diabetes


The participants will be taken from both referrals and the existing caseload of the North and East Cornwall PCT Podiatry Service and Plymouth PCT podiatry service. Each participant will be required to complete a questionnaire and sign a consent form before taking part in the study. Each participant will receive a diabetic assessment of the lower limb to determine if they present with an increased risk of foot ulceration. Identification of the increased-risk foot include a neurological foot assessment. Each participant will be randomly assigned to one of two groups:
Group 1 will receive 2 pairs of orthopaedic shoes and a custom made moulded insert
Group 2 will receive 2 pairs of orthopaedic shoes and inlay

Secondary outcome measures

Added 29 July 2008:
1. Forefoot pressure time integral
2. Total contact area
3. Rate of forefoot loading

Participant inclusion criteria

1. The subject must be diagnosed as type I or II diabetic
2. The subject must be identified as neuropathic and at risk of ulceration
3. The subject must not currently be suffering from any lower limb vascular or neuropathic ulceration identified by scoring Grade 0 on the Wagner classification for foot ulcer

Target number of participants

Sample size estimate n=130. 65 participants in each group.

Participant exclusion criteria

1. Subjects with current ulceration or recently healed less than 6 months prior to enrolling onto the study (as the focus of the study is preventative ulcer management rather than treatment)
2. Subjects with severe fixed midfoot or rearfoot deformity ie Charcot joint (subjects would be unsuitable for prefabricated insoles and non-bespoke footwear)
3. Subjects with a history of bone and joint surgery of the lower limb including amputation (could lead to alteration in gait kinetics and may not be suitable for non bespoke insoles and footwear)
4. Subjects lacking the ability to comprehend simple instructions and comply with the study protocols and procedures (including those not able to read printed English)
5. Allied Health Professional students as they may be considered to have a dependant relationship with the investigator
6. Subjects diagnosed as neuropathic caused by pathology other than diabetes
