Description of intervention(s) / exposure
This physical activity observational cohort study will examine association of physical activity (including sleep patterns) with time to healing and recurrence rates in people with VLUs using the accelerometer.

This proof of concept study will test the methodology of using the ActiSleep-BT accelerometer (ActiGraph, Pensacola, Florida) (accelerometer), recruitment feasibility and participant accelerometer acceptability in order to inform a large scale national clinical trial. It will also investigate the relationship between VLU healing and physical activity levels (including sleep patterns).

Participants will be recruited from the wound clinics in three Melbourne public hospitals currently recruiting for the ASPiVLU RCT (ACTRN12614000293662). Taking advantage of the screening process, patients ineligible for the ASPiVLU RCT are currently being recruited into the ASPIVLU Observational Cohort Study (ACTRN12618000236291). These patients will also be invited to participate in the ASPiVLU Physical Activity Observational Cohort Study.

Consenting patients will be followed for 24 weeks from the date of consent. The patient will be given questionnaires for completion at the baseline visit. Subsequent questionnaires will be mailed to the patient at 12 and 24 weeks from screen visit and followed up by phone if not returned within 2 weeks. Information will also be collected from the patient’s medical record. Between baseline and Week 12, participants will be asked to wear an accelerometer (for 7 days) and complete a physical activity questionnaire, keep a diary to record wake and sleep times and device removal greater than 15 minutes each day and evaluate the acceptability of wearing the accelerometer.

Outcomes
Primary outcome [1] 305155 0
The primary outcome is time to healing of target ulcer at 12 weeks. Healing is defined as 100% epithelialisation with no exudate or scab. Time to healing will be measured in weeks from date of consent / enrolment.
Timepoint [1] 305155 0
12 weeks post-baseline
Secondary outcome [1] 344352 0
Time to healing of target ulcer: (24 week or until healed whichever comes first). Ulcer size and duration will be recorded from medical record wound assessment forms.
Timepoint [1] 344352 0
Until ulcer is healed, up to a maximum of 24 weeks post-baseline
Secondary outcome [2] 344353 0
Recurrence of target ulcer: (24 weeks) Absence of recurrence is defined as healed at 12 weeks and recurrence free at 24 weeks.
Timepoint [2] 344353 0
24 weeks post-baseline
Secondary outcome [3] 344354 0
Adherence to compression treatment: (12 and 24 weeks) Participants will be asked to report whether they adhere to wearing the compression on a categorical scale.
Timepoint [3] 344354 0
12 weeks and 24 weeks post-baseline
Secondary outcome [4] 344355 0
Health-related quality of life and wellbeing index: (Baseline, 12 and 24 weeks): The EQ-5D is a health related quality of life and wellbeing instrument.
Timepoint [4] 344355 0
12 weeks and 24 weeks post-baseline
Secondary outcome [5] 344356 0
Physical Activity: (Baseline, 12 and 24 weeks). Physical Activity will be assessed using the Rapid Assessment of Physical Activity (RAPA); a questionnaire which asks participants to select one of seven statements which describe light, moderate or vigorous activity levels.
Timepoint [5] 344356 0
12 weeks and 24 weeks post-baseline
Secondary outcome [6] 344357 0
Physical Activity: The International Physical Activity Questionnaires (IPAQ) will be used to assess kinds of physical activities that people do as part of their everyday lives which are considered to estimate total physical activity in MET-min/week and time spent sitting (REF below). Data will be collected at Baseline.
Timepoint [6] 344357 0
Baseline
Secondary outcome [7] 344358 0
Physical Activity: The ActiSleep-BT accelerometer (ActiGraph, Pensacola, Florida) will be used to collect physical activity and sleep data. Light-intensity physical activity, and moderate- to vigorous-intensity physical activity and sleep pattern characteristics will be assessed. Participants will be instructed to wear the ActiSleep-BT accelerometer (ActiGraph, Pensacola, Florida) for 7 days during the 12 weeks between Baseline and Week 12. Participants will be asked to complete a self-report daily log to record wake and sleep times and device removal for more than 15 minutes during the 7 days of accelerometer wear.
Timepoint [7] 344358 0
7 days during the 12 weeks between Baseline and Week 12
Secondary outcome [8] 344360 0
Feasibility and acceptability of using the accelerometer will be evaluated using a feed-back survey included in the self-reported daily log booklet. Items of interest include, ease of wear, placement, comfort during sleep, length of time worn and completion of daily log
Timepoint [8] 344360 0
At the end of the 7 days of accelerometer wear
Secondary outcome [9] 344361 0
Wound Pain Score: Participant’s self-reported assessment of pain associated with their VLU during the past week will be measured with an 11 point (0-10) numerical rating scale, where a score of ‘0’ represents no pain and a score of ‘10’ represents the maximum pain imaginable. Data will be collected at Baseline, 12 and 24 weeks.
Timepoint [9] 344361 0
12 weeks and 24 weeks post-baseline
Secondary outcome [10] 344362 0
Adherence to compression: Participants will be asked to report whether they adhere to wearing the compression on a categorical scale specific to this study of "wear every day", "wear most days (3 days per week or more)", "wear some days (less than 3 days per week)", "do not wear". Data will be collected at Baseline, 12 and 24 weeks. Information on compression use will also be collected from the patient’s medical history.
Timepoint [10] 344362 0
12 weeks and 24 weeks post-baseline

Statistical methods / analysis
As this is a pilot study, sample size calculations are not required (Larkin 2017). We plan to recruit 20-40 participants to test the feasibility of recruitment and determine sample size for a future large scale randomised control trial. It will also assess the feasibility and participant acceptability of wearing an accelerometer and data output from the ActiSleep –BT Accelerometer (Actigraph, Pensacola, Florida) as a means of assessing physical activity and sleep in venous leg ulcer patients as well as exploring the relationship between physical activity (including sleep) and healing outcomes in VLU patients.

Correlations with physical activity (including sedentary time) and sleep time will be assessed for the following variables: wound size, duration, healing rate (change in area over time up to 12 weeks), time to healing and time to first recurrence.
Data will be controlled for gender, age, smoking status, diabetes history, and BMI. Parametric and non-parametric tests will be used accordingly and statistical significance will be set at p=0.05. Post-hoc correction will be used to control for multiple comparisons.
