About

The primary aim of this study is to evaluate the feasibility of a full randomized clinical trial for assessing the effects of pain education as an intervention for patients with LBP in a physiotherapy facility in Nepal. The primary objectives of the study are related to feasibility of randomized clinical trial including: (1) willingness to participate in a clinical trial, (2) acceptability of random allocation to one of the two study groups, (3) feasibility of blinding the assessor(s), (4) eligibility and recruitment rates, (5) acceptability of screening procedures, (6) possible contamination between the groups, (7) credibility of pain education for patients with LBP, (8) adherence to intervention, (9) satisfaction of treatment, and (10) difficulty in understanding the content of pain education.

To address the study objectives, an assessor-blinded, two arm randomized feasibility study was designed. Forty patients with LBP will be randomly allocated to one of the two study arms, (1) pain education in the experimental group, and (2) evidence based care in the control group (CG).

Full description

This is a feasibility study that is being performed to determine if a full randomized controlled trial (RCT) can be successfully conducted and if it should be conducted. The definition of a feasibility study highlights the question, "Can this study be done?" The SPIRIT statement and the CONSORT statement- extension to pilot and feasibility randomized study will be followed in the planning and reporting of the protocol and the manuscript of this feasibility study respectively.

The study will be assessor blind two-arm feasibility clinical trial study. Ethical approval was obtained from the Nepal Health Research Council (NHRC) and University of Otago Human Ethics Committee. The study will be conducted in the Sahara Rehabilitation Hospital, Kathmandu, Nepal which is a private hospital in Kathmandu, Nepal.

Overview of the study: Advertisement of the study will be made in social media. Interested candidates will be screened for eligibility. Eligible patients with LBP will be enrolled in the study. Participants will be randomly assigned to one of the two groups. All the participants in the experimental group will receive pain education and those in the control group will receive usual (evidence based) physiotherapy care. All the participants will be assessed at baseline, and follow-up assessment approximately after a week of randomization.

Participant screening and recruitment: Consecutive participants with non-specific low back pain will be invited to participate in this study. Interested candidates will be explained the study purpose, benefits and harms of the intervention, time required for the completion of the study, follow-up duration, voluntary nature of participation, cost of participation, and the rights to withdraw from the study at any point. A participant information sheet will be provided to all potential participants. If the potential participants are interested in participating, they will be screened for eligibility by a research assistant who is a physiotherapist. If the participants are found eligible, informed consent will be obtained. For those who cannot sign the consent, a witness will sign on their behalf, or the study participant will provide a thumb print on the form for those who cannot write or sign the form as per the ethical guidelines provided by NHRC. Patients with no education and who cannot sign an informed consent will be included in order to increase the inclusion of uneducated or low education group, given that 31% people in Nepal who are five years old or more cannot read and write. Additionally, exploration of feasibility of pain education in those with no schooling or low educational attainment is important in order to inform clinical practice.

Participants will be informed that they will receive one of the two treatments randomly. It will be highlighted that both of the treatment options are thought to be effective for low back pain, and that the goal of the main study is to compare the interventions, however the current study will more specifically evaluate the feasibility of such a study. There will be no restriction on the participants on both the groups in the pharmacological interventions they receive, however, participants in the intervention group will be restricted on receiving other physiotherapy interventions on day 1 only. All the participants will continue to receive the regular interventions provided by the centre from the second visit after follow-up assessment in the second week.

Group Allocation, Randomization and Blinding: Random number sequence will be generated by a researcher not involved in data collection or providing treatment using www.random.org. Allocation concealment will be performed using opaque, sealed envelopes. The participants will be allocated to one of the two groups by a hospital staff who is not the assessor. The two groups are: Group 1: Pain education group (PEG); and Group 2: Control group (CG).
