Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be required to attend 4 x 2 hr education and exercise sessions (weeks 1-4) at Griffith University (Mt Gravatt or Nathan campuses) or University of Queensland (St Lucia campus). The sessions will be group based (4-6 participants). Over the four weeks, participants will interact with a Musculoskeletal Physiotherapist and Accredited Exercise Physiologist (AEP) t. At the first session participants will be given a fitness wristband (to keep) that measures heart rate when exercising to calculate a weekly Physical Activity Intelligence (PAI) score. PAI is an innovative, scientifically valid and easily understood metric that informs individuals about the quantity and intensity of physical activity needed to obtain or sustain good health.

Each session will consist of PAI-learning, PAI-playtime and PAI-behaviour change. During PAI-learning (~30mins of demonstrations, group activities, led by AEP or physiotherapist) participants will learn how to use the PAI app on their smartphone, how to activate heart rate recording and how to troubleshoot problems. During PAI-playtime (~ 1hr), an AEP or Physiotherapist will guide participants through short bouts (of 5-10minutes) of different types and intensities of exercise (including flat walking, hill/stair walking, high intensity intervals, body weight resisted exercise (squats, pushups, calf raises) to see the different ways PAI can be obtained. During PAI-behaviour change (~ 30mins) patients will be encouraged to self-reflect and discuss strategies to adopt and maintain physical activity targets using the PAI app to monitor adherence. These discussions will be facilitated by a Musculoskeletal Physiotherapist following training by a Clinical Psychologist. Participants will be advised to gradually increase their activity over the first four weeks to achieve a PAI score of at least 100 points/week by four weeks.
By the end of the 4 weeks, participants shall be able to use the PAI App, connect App to the wristband, sync data, and know where to get help if they experience any App-problems throughout the study period, know how to mix and match exercises of varying modality and intensity to reach 100 PAI points/week. Participants will be asked to engage in activities to keep their PAI score above 100 points for as many days as possible during weeks 5-12 of the intervention period. Participants will be asked to report any adverse events to the staff during the intervention or follow-up period.

Outcomes
Primary outcome [1] 319998 0
Proportion of participants that complete the study
Timepoint [1] 319998 0
12 weeks post randomisation (control) or 12 weeks post commencement of PAI e-Health program
Primary outcome [2] 319999 0
Adverse events including extreme breathlessness, chest pain, musculoskeletal events, hypoglycaemia, falls, acute illnesses, changes in health status or medications, will be recorded by a paper based diary.
Timepoint [2] 319999 0
Adverse events will be documented by the Accredited exercise physiologist (AEP) or Physiotherapist at each visit during phase 1. During phase 2, participants will contact research staff if they note adverse events.
Primary outcome [3] 320000 0
Adherence to the PAI program will be evaluated as the number of days during the intervention that the participant achieves 100 PAI points. Week 1 data will be excluded as it takes 7-days to accumulate PAI.
Timepoint [3] 320000 0
Daily during the intervention, excluding week 1 (it takes 7-days to accumulate PAI).
Secondary outcome [1] 370145 0

Eligibility
Key inclusion criteria
Community dwelling adults aged 30-70 years, ambulant without aids, with a medical diagnosis of type 2 diabetes and DSPN. Participants will be screened for diabetic neuropathy using ankle-reflex, monofilament and vibration tests, with positive results identified by absence of bilateral Achilles tendon reflex, 10g monofilament sensation or 128-Hz tuning fork vibration perception threshold of lower than four. Nerve conduction tests will be performed to evaluate lower limb peripheral nerve function if feasible (researcher availability and participant consent). Participants must have a smart phone and be willing/able to complete testing, training and surveys.
Minimum age

Statistical methods / analysis
Descriptive statistics will be used to analyse the proportion of participants completing the study; adherence to the PAI face:to:face sessions; adherence to 50, 75 and 100 PAI points and adverse events.

To obtain estimates of intervention effects, we will compare physical activity, neuropathy specific quality of life, neuropathy and musculoskeletal symptoms between baseline and 12 weeks using paired t-tests for each outcome measure. Alpha will be set at 0.05, and power at 80% for all statistical analysis. Since this is a feasibility study, we will not adjust alpha for multiple comparisons. This will decrease the chance of Type II error, increasing the chance of identifying potentially important differences between groups. This statistical approach is considered appropriate for feasibility or exploratory studies.
