Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The proposed intervention will consist of the clinical pathway augmented by a 6-months disruptive technology package to optimise engagement and adherence to the post-surgical rehabilitation program. The intervention will be delivered by a study coordinator through apps installed in the study iPad. The technology package will be composed of:
• a daily exercise program (please see details below) delivered via a health fitness app (PhysiApp®) which will be monitored using Physitrack® (the clinician portal)
• daily physical activity tracking using a wearable tracker (Fitbit®) built-in with motivational reminders and used in combination with the Fitbit app
• a weekly health-coaching delivered by a certified health coach via video-conferencing software (Zoom® app) and motivational text messages via iMessage (Apple®)
• a knee joint ROM measuring app (Goniometer Pro®) for total knee replacement participants to measure and record ROM during each health-coaching session

Exercise program
A 6-month exercise program was created by a physiotherapist after consultation with a surgeon, a rheumatologist and a patient representative using Physitrack®, which is specifically for lumbar decompression and total knee replacement, respectively. The exercise program focused mainly on strengthening, ROM and neural gliding exercises (the latter was limited to lumbar decompression participants). There will be no special equipment needed for the participants except for a chair or exercise mat.
Each program is comprised of 3 levels of difficulty with independent progression for strengthening and ROM/neural glide exercises.
The exercise program will be delivered to the participant via PhysiApp, which will record the participant’s adherence to the exercises (number sets and repetitions performed). Participants will be asked to rate their pain intensity experienced during exercises.

Treatment Adherence
Frequency of exercise/physical activity over the last week will be used to assess adherence. Satisfactory adherence to the intervention will be defined as completion of at least 80% of the prescribed intervention.
Adherence to the experimental intervention will be measured through a combination of self-reported and objective measures including adherence self-reported questions, data from activity devices, Physitrack app and logs maintained by the study coordinator.

Rehabilitation
Comparator / control treatment
The comparator treatment will be comprised of the standardised post-surgical rehabilitation care. The control will also receive an activity tracker (Fitbit) to allow the monitoring of physical activity, however without motivational messaging. To ensure participant retention, we will offer healthy lifestyle advice after each fortnightly health care usage survey. The experimental group will also receive lifestyle advice messages.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation will be concealed by automated assignment using the REDCap randomisation module. Due to the type of intervention, participants and the researchers delivering the intervention will not be blinded to the treatment allocation. The site staff, principal investigators and study statistician will remain blinded to the treatment allocation until the main results are analysed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Individuals who qualify and consent to take part in the study will be assigned to either experimental or control group with a 1:1 allocation rate as per computer-generated randomisation scheduled using random permuted block sizes and stratified by study sites. A separate randomisation schedule will be created for each type of surgery (total knee replacement and spinal surgery).

Efficacy
Statistical methods / analysis
The analysis will be based on the intention-to-treat principle and conducted by surgical procedure (i.e. TKR and lumbar decompression). Statistical significance will be defined as P<0.05 on the basis of a two-sided test.

Descriptive statistics of baseline characteristics will be summarised by randomisation group and type of conditions (i.e. post-TKR and post spinal surgery). Continuous variables will be summarised as mean (SD) where appropriate or median (range). Categorical variables will be summarised as frequency (%). Pain scores as 3 months will be summarised as mean (SD) or median (range) if non-normal. The primary analysis for the difference in pain will be assessed using t-test if normally distributed or a Mann Whitney test if non-normal. Secondary outcomes including a secondary analysis of pain (at 6 and 12 months) will be investigated using generalised estimating equation, this takes into account the repeated measures of the data. Analyses will be performed separately for each condition. A time-by-treatment interaction will be included in the models alongside the main effects to assess the effect of treatment over time. Additional analyses will also be performed, adjusting the models for relevant baseline scores, demographics and clinical characteristics. In case of non-compliance with treatments before the 6 and 12-month follow-up, a sensitivity analysis (among only those who completed the follow-up questionnaire) will also be performed excluding those who were non-compliant. Missing data will be checked for randomness and data missing at random will be imputed using multiple imputations.
