Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Electrical acupuncture will be applied to the arms and legs. During the treatment, electrical current delivered with a battery-operated eletrical stimulator is combined with acupuncture needle techniques to enhance stimulation of the acupuncture points. Each treatment session takes 25 to 30 minutes. The treatment will be given twice a week for four weeks followed by once a week for two weeks then once every two weeks for four weeks. In total, 12 sessions are delivered within 10 weeks.

Participants in this group will also receive pain and medication management (i.e., standard care).

Treatment: Devices
Comparator / control treatment
Conotrol arm 1: Sham electroacupuncture control.
This group will receive similar treatment to that delivered to the real electroacupuncture group. Each session takes 25 to 30 minutes. In total, 12 sessions of treatment are delivered within 10 weeks.

Participants in this group will also receive pain and medication management (i.e., standard care).

Control arm 2: Standard care control (pain and medication management)
This group will receive pain and medication management for 10 weeks without electroacupuncture treatment.
Control group
Placebo

Outcomes
Primary outcome [1] 238078 0
The weekly dosage of opioid medicaitons (OM). This will be calculated based on the data recorded by the pariticipants in their Pain and Medication Diary.
Timepoint [1] 238078 0
At the end of the treatment period, i.e. 10 weeks following randomisation.
Secondary outcome [1] 242269 0
1) Number of participants who achieve 50% OM reduction
Timepoint [1] 242269 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.
Secondary outcome [2] 242270 0
2) Type, severity and incidence of OM related common adverse events (AEs). Common AEs are somnolence, mental clouding, nausea and constipation. They are assessed with six-point scales (0 = none, 1 = minimal, 2 = mild, 3 = moderate, 4 = severe, and 5 = extremely severe) to indicate the severity of these events. The scales are included at the end of Pain and Medication Diary that is completed by the participants.
Timepoint [2] 242270 0
at the end of the treatment period, i.e. 10 weeks following randomisation
Secondary outcome [3] 242271 0
3) Pain intensity measured with Visual Analogue Scales (VASs; 0 = no pain; 10 = worst pain possible) and with the numerical scales included in the Brief Pain Inventory
Timepoint [3] 242271 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.
Secondary outcome [4] 244686 0
4) Consumption of non-opioid medications that are recorded by the participants in their Pain and Medication Diary. To make meaningful comparisons of non-opioid medications use, the dosage of such medications will be calculated according to Medication Quantification Scale Version III (MQS).
Timepoint [4] 244686 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.

5) Quality of life assessed with SF-36v2 Health Survey
Timepoint [5] 244687 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.
Secondary outcome [6] 244688 0
6) participants' attitude of paina as assessed with Survey of Patients Attitude.
Timepoint [6] 244688 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.
Secondary outcome [7] 257052 0
7) The level of function assessed with the Roland-Morris Disability Questionnaire (RMDQ) and the Brief Pain Inventory;
Timepoint [7] 257052 0
At the end of the treatment period, i.e. 10 weeks following randomisation; and
at the end of the follow-up period, i.e. three months after the end of the treatment.
Secondary outcome [8] 257053 0
8) The presentation and severity of withdrawal symptoms assessed with Short Opiate Withdrawal Scale.
Timepoint [8] 257053 0
At the end of the treatment period, i.e. 10 weeks following randomisation
Secondary outcome [9] 257054 0
10) The proportion of neuropathic versus nociceptive pain assessed with the Self-administered Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (S-LANSS)
Timepoint [9] 257054 0
At the end of the treatment period, i.e. 10 weeks following randomisation
Secondary outcome [10] 257055 0
11) The Perception of EA Treatment Questionnaire will be given to the two electroacupuncture groups to assess the success of blinding
Timepoint [10] 257055 0
In the 6th and 14th weeks, i.e. two and 10 weeks following randomisation.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential subjects will be recruited from two pain management centres in Melbourne. After a four-week run-in period, subjects who meet all selection criteria will be randomly allocated into one of the three groups, namely real electroacupuncture, sham electroacupuncture or no electroacupuncture with a 2:1:1 ratio. Central randomisation by phone will be used. The acupuncturist is the only person who will know the treatment allocation. All other clinicians and reseachers will be blinded to the treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
An automated telephone randomisation service will be used.
Masking / blinding
Blinded (masking used)
