Description of intervention(s) / exposure
Podiatrist Intervention:
i. Short face-to-face lecture and demonstration training session (90 - 120 minutes) conducted for two podiatrists in using a health coaching approach to issue the SurroSense Rx smart-insole. Session will be held in an outpatient clinic. Health coaching training will be provided by an experienced health coach with > 5 years of experience using the technique. Health coaching utilises a range of techniques to assess a person’s readiness to change, assist them to identify health care goals and the specific steps and actions that support achievement of these goals. Techniques may include teach-back, goal-setting techniques such as Specific, Measurable, Achievable, Relevant and Time-related (S.M.A.R.T) goals, motivational interviewing and patient education.
ii. 30 - 45 minute face to face demonstration session for podiatrists in how to use the SurroSense Rx smart-insole. Training will be provided in an outpatient clinic to a group of 2 podiatrists by a study researcher who is a registered podiatrist and has prior training in the use of the insole. The researcher will use SurroSense Rx insole information provided by Orpyx Medical Technologies to support podiatrist training in usage of the device.
iii. Feedback face to face session will be provided to podiatrists individually in their own practice setting. Feedback regarding their clients' summary baseline data from Nottingham Assessment of Functional Footcare questionnaire and Patient Interpretation of Neuropathy questionnaire will be provided to the device-issuing podiatrist.

Participant enrolment:
i. At enrolment, participants will be provided with information about the study and will be asked to provide written consent to participate in the study. At enrolment participants will undergo a neurovascular foot examination conducted by a registered podiatrist to confirm eligibility. At enrolment participants will be asked to complete three questionnaires; Unified Theory of Acceptance and Use of Technology questionnaire, Nottingham Assessment of Functional Footcare questionnaire and Patient Interpretation of Neuropathy questionnaire.

Participant Intervention:
Podiatrist-led, standardised face-to-face, one-on-one health coaching clinical consultation during the issuing of a SurroSense Rx smart insole from Orpyx Medical Technologies Inc (Canada) to support foot health self-monitoring and utilisation of SurroSense Rx smart-insole. The SurroSense Rx smart insole is a shoe insert that is a foot ulcer prevention system. The device uses sensors to monitor the amount of pressure applied on the plantar aspect of the foot throughout the day. When pressure areas are high, an alert is transmitted wirelessly to the person’s smartwatch. This information can be used by the wearer to modify their behaviour and off-load pressure, avoiding injury. Participants will be asked to wear the insole for every step they take and whenever they are placing their feet on the ground - no set wear time per day. Participants will be shown how to use the SurroSense Rx insole by the issuing podiatrist.
ii. Brief podiatry follow-up intervention via telephone, email or face to face with participants two weeks into the trial. Duration of follow-up consultation is determined by participant need.
iii. Participant adoption and usage of the Surrosense Rx smart insole over a four-week period.

Efficacy
Statistical methods / analysis
A convenience sample of n = 10 participant will be recruited, 5 each from a public and private podiatry clinic. The sample size is limited due to limited resources; only 10 SurroSense Rx smart insoles will be purchased within allocated funding. Despite the small sample size, a rich array of data will be collected to determine feasibility, with added depth of understanding regarding issues of adoption and utilisation provided by the mixed-methods approach.

Descriptive statics will be used to report demographic data for participants. Ratio data will be presented as mean and standard deviation, and proportions will be used for nominal data. Statistical significance for analyses will be set at p<0.05.

Audio recordings of issue appointments will be listened to and assessed for fidelity to the use of the health coaching elements during the consultation. Fidelity will be scored by an experienced health coach into high, medium and low fidelity levels to health coaching elements and bivariate analysis and regression will be used to determine if the level of fidelity to health coaching impacts participant device usage as determined by minutes worn per day, number of alerts and number of alerts successfully responded to during the four-week intervention.

Cronbach’s alpha will be used to assess the internal consistency of the UTAUT responses. Mean domain scores measured on a continuous 5 point Likert scale for the UTAUT questionnaire will be calculated and bivariate analysis and linear regression will be used to determine the relationship between key psychosocial domains and behavioural intention both before and after using the smart insole for participants.

Relationships between key variables, such as NAFF and PIN scores and insole adoption as measured by the number minutes the insole is worn each day, the number of alerts provided from the insole, the number of alerts successfully responded to by participants will be analysed using bivariate analysis and linear regression.

Transcribed qualitative data from the focus groups and in-depth interviews will be analysed using thematic analysis. Line by line coding will be completed independently by two authors.
