Plain English Summary

Background and study aims
Low back pain (LBP) is one of the most common and costly problems seen in General Practitioner’s (GP) surgeries. Internet interventions may provide a new and efficient way of supporting and encouraging patients to become more active in self-management of LBP.
The aim of this study is to determine if an internet intervention called ‘SupportBack’, provided both with and without guidance from a physiotherapist over the telephone, is effective in reducing LBP-related disability when compared to usual primary care alone.

Who can participate?
Adults with low back pain, who can speak English and have access to the internet with an active email address

What does the study involve?
Participants will be randomly allocated to one of three groups@
1. Usual care
2. Usual care + internet intervention
3. Usual care + internet intervention + telephone physiotherapist support
The internet intervention is SupportBack, which provides advice and reassurance, and encourages physical activity over a six-week period. Tailored online materials support gradual goal setting, facilitate monitoring of back-related activities and provide personalised feedback. Telephone physiotherapist support will address concerns, provide reassurance and encourage uptake and compliance with activity goals.
Participants will be followed up at six weeks, three, six and 12 months. Questionnaires will explore how LBP is affecting their daily activities, their level of pain intensity and other LBP-related issues. A GP medical records review will be performed at 12 months which will record health care service use. LBP related costs will be calculated. In-depth interviews will be conducted with up to 30 trial participants across the three groups to explore their experiences of SupportBack and the care they have received over the trial period.
As well as GPs, psychologists, physiotherapists, rheumatologists and statisticians, the team will include members of the public with experience of LBP who will provide input at all stages of the study.

What are the possible benefits and risks of participating in this study?
SupportBack is a low intensity behavioural intervention, where participants either alone or with brief support from a physiotherapist, work through LBP-related internet-based modules and set physical activity goals. Therefore, the benefit of participating is that participants may experience relief from LBP symptoms.
As participants set their own activity goals, they are unlikely to over-exert themselves. Subsequently, SupportBack is a low risk behavioural intervention. Nonetheless, participants will be made aware of indicators of serious spinal pathology, and advised to seek immediate medical attention if they should arise over the trial period.
As part of the study, participants will be asked to complete questionnaires at five time points across the 12 month study period. Those in the internet intervention groups will be expected to access SupportBack online. It is possible that some may experience the questionnaires as an inconvenience. However, participants will be informed that they can take regular breaks when completing the questionnaires, and they will be able to skip some secondary questionnaires, if they start to find completion burdensome. The Participant Information Sheet clearly explains how long the SupportBack internet intervention will take each week and participants can therefore decide if they have time to dedicate to the study prior to consent.

Low back pain


Following completion of consent and baseline questionnaires, the internet intervention software, LifeGuide, will randomise the participant. The randomisation sequence will be automatically generated, and a computer-generated algorithm will block randomise participants to the trial groups. Participants will be stratified by level of severity, with a score of less than four on the Roland Morris Disability Questionnaire being considered as a lower level of severity, and trial centre. As the software randomises participants, the sequencing will be concealed from the Research Team. Participants will be automatically informed of their allocated group via the internet through the intervention website. As the intervention is primarily behavioural, participants will not be blind to allocation.
Participants will be randomly allocated to one of three groups:
1. Usual care
2. Usual care + internet intervention
3. Usual care + internet intervention + telephone physiotherapist support

Usual care:
Participants allocated to this arm will continue to receive usual primary care. In the first instance, NICE recommended care for LBP consists of education and self-management advice, including advice to stay active. GPs may also prescribe medications for LBP and/or make referrals to other services that can offer other recommended treatments such as exercise programmes, manual therapy or psychological and/or pain management programmes. With regard to pharmacotherapy, recommendations are for NSAIDs or weak opioids only if NSAIDs are contraindicated, not tolerated or ineffective. Paracetamol is not recommended, neither is the routine use of opioids for LBP. Antidepressants (SSRIs or Tricyclics) are not recommended for LBP. In practice, many GPs do not adhere to guidelines for LBP, consequently, the latest NICE guidelines for LBP will be highlighted with all participating practices in a telephone call as part of the trial setup. Nonetheless, it is likely that treatment received as part of usual care will vary, and this variation will be ascertained and documented by a medical records review at 12 months and participant borne costs questionnaires at baseline, six months and 12 months. If a participant does not re-consult over the trial period they may receive no additional care beyond that which they received as part of their initial GP consultation, whereas some participants may receive ongoing care from the GP, and/or referrals for diagnostic tests or treatments from other healthcare professionals such Physiotherapists or other specialists.

Usual care + Internet intervention:
Participants allocated to this arm will continue to receive usual primary care. In addition, they will receive access to SupportBack. SupportBack is an interactive multi-session internet intervention that provides participants with accessible information, tools and support to enable them to effectively manage their LBP. Internet provision allows the material to be accessed, and the suggested activities to be carried out wherever is most convenient for the participants. The intervention was developed using the open source LifeGuide software ( The core of the intervention is focused on self-regulatory processes including graded goal setting, self-monitoring, and tailored feedback to encourage physical activity/exercise increases or maintenance. The intervention also provides educational advice regarding pain and LBP-related topics. Throughout, the included educational information has a focus on motivating behaviour change through techniques such as reassuring participants about likely consequences of movement and physical activity; helping participants interpret mild pain; modelling managing pain through physical activity using patient stories; reinforcing positive behaviour (using automated feedback); and providing simple instructions/ demonstrations regarding how to perform various back-specific exercises/physical activity behaviours. By combining the above features with in-depth feedback from patients with LBP in development, SupportBack is designed to be a highly accessible intervention supporting changes in self-efficacy and physical activity in order to improve LBP-related physical function.

The SupportBack internet intervention comprises six sessions delivered over a period of up to six weeks. Participants are encouraged to access one session per week, to allow them to engage between sessions with the activity goals they have set themselves. Participants are sent automated emails each week as a reminder to login to their next session. Specifically, in the first session participants are provided with information on how SupportBack will work, including the key rationale underlying the intervention; that keeping active is of primary importance when managing LBP. Likely concerns/potential barriers regarding this primary message are also addressed. The intervention then suggests two forms of physical activity participants can be supported with each week; walking or simple back-specific exercises. Participants select one and set goals for the coming week. The recommendations provided are tailored, based on the extent participants report their LBP is obstructing their ability to engage with activities in their day-to-day lives.

From session two onwards, the intervention follows the same format. Participants review their goals from the previous week and are provided with automated tailored feedback and encouragement. They then have the opportunity to amend their goals, increase difficulty or switch to different physical activities. From session two, after a participant’s goal review they can choose to explore one of six modules containing information and advice on a LBP-related topic (see Table 2 for details). Exploration of these information modules becomes part of each broader ‘session’. Although participants are advised to work through a session per week, they can view a new session every three days if they wish. If engaged with as recommended, the intervention would take six weeks to complete. After the six weeks of structured sessions, participants will still have access to activity information and LBP-related modules as a static website. The intervention is fully automated and adherence is encouraged through weekly reminder emails containing links back to the intervention.

Usual care + internet intervention + telephone physiotherapist support:
Participants allocated to this arm will continue to receive usual primary care. The SupportBack internet intervention will also be offered to participants with the addition of up to one hour of telephone support from an NHS Physiotherapist, over the same period of six weeks. The supporting Physiotherapists will be drawn from those who assess and manage patients with LBP in NHS services linked to participating GP practices. In Southampton, musculoskeletal Physiotherapists will come from Solent NHS Trust whereas in Keele they will be NIHR CRN Research Musculoskeletal Physiotherapists from the West Midlands CRN. Physiotherapists will receive participant contact details via an email account or Dropoff, a UoS secure file transfer system.

Although support will vary with participant need, it will not exceed one hour in total (but could be less) and consists of one up to 30-minute phone call followed by two up to 15-minute phone follow-ups over six weeks. The purpose of the Physiotherapist telephone contact is to provide support and encouragement for use of the internet intervention and to address participants’ concerns in relation to the internet-based content. The Physiotherapists are asked to closely adhere to a standardised content checklist for each phone call. Whilst they are able to address individual participant concerns, they are asked to avoid additional individualised participant assessment and treatment recommendations beyond the internet intervention content and adherence to this protocol will be assessed. Paper based notes made during the telephone Physiotherapist support will be stored securely at SCTU.

Call one (up to 30 minutes) is planned to take place between weeks one and two after randomisation. In this call, the Physiotherapist explores and addresses the participant’s understanding and attitudes (e.g. belief that activity can be helpful for LBP); engagement with the internet intervention (e.g. enquiring how the participant has got on with their goals); and anticipates barriers (by asking what problems they anticipate in participating in the SupportBack programme). Calls two and three (up to 15 minutes) are planned to take place between weeks two and three, and between weeks four and five. In these telephone calls the Physiotherapist discusses general adherence to the internet content and internet sessions; provides positive reinforcement for adherence behaviour to both the internet intervention and physical activity goals; discusses barriers to adherence and how these might be addressed; encourages commitment to goals for the following week; and addresses any remaining concerns.

Participants will be followed up at 6 weeks, and 3, 6 and 12 months.
