Interventional
Description of intervention(s) / exposure
Group-1 will receive Electroencephalography-Neurofeedback (Brainwave) training + usual care.

Electroencephalography- Neurofeedback (EEG-NF) training is a form of biofeedback training designed to self-regulate activities of targeted neural areas to improve health outcomes. EEG-NF works under the principles of operant conditioning learning. Real-time feedback (reward) is provided to the participant on reaching a threshold level of the cortical electrical activity at the targeted brain regions linked to the pain experience, thereby supporting self-regulation of pain and health. In this trial, Electroencephalography (EEG) neurofeedback will be administered four times a week (30 minutes/ session) for a total of 3 consecutive weeks, by trained research personnel. During each session, participants will be asked to close their eyes and sit relaxed on a chair with back support. The Comby EEG lead cap with sensors will be placed on the individual’s scalp. The targeted brain region will include the pregenual anterior cingulate cortex (pgACC). The Brainmaster Inc. system delivers sound feedback (reward) each time the participant’s real-time brain activity at the targeted region meets the desired infraslow threshold (0.0–0.1 Hz) at the targeted cortical area(s). The reward threshold will be adjusted in real-time between 60-80%, i.e., for 60-80% of the time.

Group-2 will receive Mindfulness Meditation Training (MMT) + usual care.

Mindfulness Meditation Training (MMT): The MMT regimen will consist of twelve 20 minutes sessions which will be administered for three successive weeks with four sessions each week. A trained research assistant will administer the training. During each session, participants will be instructed to focus on the sensation of each breath occurring at the tip of the nose. On progression, participants will be instructed to broaden their focus to the "full flow of the breath", including bodily sensations. We will instruct participants to acknowledge thoughts, feelings, and emotions as they arise without judgment and "simply return their attention back to the breath sensations".

Participants in groups 1 and 2 will continue to receive the usual, normal routine care offered by their healthcare providers and carry out self-management strategies.

Adherence to training will be recorded through attendance at each training session.

Monitoring usual care: Participants (in groups 1 & 2) will record healthcare interventions received and self-management strategies carried out on a weekly basis during the training period. This would be recorded using a self-report questionnaire (digital or paper format).

Usual care group (group-3): Participants will continue to receive healthcare interventions and carry out self-management strategies. They will be asked to refrain from practising any forms of mindfulness/meditation strategies during the study period. Following the 3 months post-intervention follow-up assessment, they will be offered to receive one of the active interventions. Participants in the usual care group will record healthcare interventions received and self-management strategies carried out. This would be recorded using a self-report questionnaire (digital or paper format).

Safety of training: The Discontinuation-Emergent Sign and Symptom (DESS), a 43-item checklist consisting of emotional, behavioural, cognitive and physical symptoms, will be used to record symptoms compared to the status prior to the training or the previous session. For each symptom, participants will have to choose from one of the following categories: new symptom; old symptom but worse; old symptom but improved; old symptom but unchanged and symptom not present. Participants’ views of the causal relationship of symptoms with the intervention will be measured using an ordinal item ranging from 1 (unrelated) to 5 (strongly related). Participants will also be encouraged to report any other symptoms that were not captured in the DESS checklist. The participants will have to report worsening side effects compared to the status before the training or the previous session. Options for open comments will be provided.

Heart Rate Variability: Resting heart rate and beat-to-beat R-R interval within 2-ms resolution will be obtained using a Polar V800 HR monitor and a Polar H10 chest Pro Strap. All participants will be seated, and the data will be collected for 7 minutes. Automated office blood pressure measurement will be used to measure blood pressure (BP) readings with participants resting in a quiet room. The respiratory rate will be measured. Raw heart rate and R-R interval time series data will be downloaded from the Polar flow software for further processing and analysis. Kubios software https://www.kubios.com/hrv-premium/ will be used to derive heart rate variability (HRV) from R-R interval record exported from polar flow in the time and frequency domains. Heart Rate Variability (HRV) measures are linked to pain severity ratings and a potential mediator of training outcomes.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment: The allocation of groups will be concealed using opaque envelopes (one for each allocation, numbered in order) to conceal the sequence until interventions were assigned. The senior biostatistician will prepare and then provide the opaque sealed envelopes to the assistant research fellow (ARF).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation: Following baseline assessment, participants will undergo allocation into one of the three study groups with equal probabilities. Blocks of unequal length, with the lengths and the probabilities of these lengths not known to other investigators, will be used to promote allocation concealment. The senior biostatistician, using non-informative group allocation codes (where the unblinding will not be revealed to them until all planned analyses are completed), will generate the allocation sequence using standard computer software. The ARF will give the opaque sealed envelope to the research assistant, who will disclose the intervention to the participants and administer one of the active interventions: a) MMT +usual care, b) EEG-NF training +usual care. If a participant is identified to be allocated to the usual care control group, they would be advised to continue managing their health condition as they regularly do and appear for the assessment sessions.
