Primary purpose: TREATMENT

Brief summary: Low back pain (LBP) is a common clinical symptom prompting patients to seek medical care. 80% of adults experience LBP during their lifetime. The causes of CNLBP are still not fully elucidated and there is currently no gold standard treatment for CNLBP. The mainstay of conservative treatment for CNLBP includes pharmacological interventions, weight loss and physiotherapy.

More recently, Tuina, a component of Traditional Chinese Medicine, has been used to treat CNLBP as well. Tuina is mainly applied to the meridians or acupoints by manipulation techniques such as pushing, grasping, pressing and rubbing of the soft tissues or muscles of the body. It is reported to improve circulation and the qi in the body. However, recent systematic reviews on the efficacy of Tuina in the management of CNLBP were not able to definitively conclude the effectiveness of Tuina due to the poor methodological quality of the studies.

Therefore, this study is a single blind, randomized controlled trial (RCT), which aims to determine the efficacy and safety of Tuina in the management of CNLBP. Similar studies are also conducted in China (First Affiliated Hospital of Jinan University) and USA (Mayo Clinic).

Patients from SGH Orthopaedic clinics with CNLBP, will be recruited for this RCT, and will be randomly divided into 3 intervention groups: Physiotherapy intervention group as the control group, Tuina intervention group, and combined intervention (Tuina + Physiotherapy) group. The intervention will last for 2 months, and follow up assessments will be conducted at the 5th month. Outcome measures include Visual Analog Scale (VAS), Spinal range of motion, Oswestry Disability Index (ODI), TCM Syndrome scale and quality of life 36 item short form survey, (SF-36).

Detailed description: This is a randomised controlled study, single blind with the assessor blinded to the intervention groups of the study.

204 patients (68 per group) with CNLBP will be recruited from the Outpatient Spine Clinic of the Department of Orthopaedic Surgery, SGH, as referred by the Orthopaedic Surgeons.

They will be screened by the assessor, using the inclusion and exclusion criteria listed in K1 and K2 and if consent is given, baseline assessment of the outcomes variables will be conducted. After assessment, the subjects will be randomized into Tuina (TN) group and control physiotherapy (PT) group and Tuina combined physiotherapy (TP) group in a 1:1:1 ratio by the PI. Stratified blocked randomization method will be used in this study. The assessor remainds blind to the treatment groups for all outcome assessments. Standard Physiotherapy and Tuina procedures will be used in the treatment of the subjects according to their presenting symptoms. Education and home exercises will also be taught as appropriate. All subjects will be provided with a maximum of 6 treatment sessions, after which a post-intervention assessment will be conducted.

The intervention that is not standard is the combination of Tuina and Physiotherapy sessions, which is the intervention in Group TP.

Due to the particularity of Tuina and the PT intervention, the operators or intervention providers and the patients are not blinded to the treatment group. The Research Accessors perform the baseline evaluations and follow-up observation, and statistical analysis, hence they will be blinded in this study.

Each group will perform 6 sessions of Interventions over a period of 2 months. However, if the subject improves completely before the completion of the 6 sessions, they need not continue with the remaining sessions.

Criteria for discharge or to discontinue physiotherapy when the subject has improved completely based on the following:

1. Patient able to reach SMART goals set at initial physiotherapy/Tuina visit.
2. Patient feels that he/she is able to manage condition independently.
3. Patient's pain levels are well controlled and/or functional goals have been met.

In all cases, a follow up of the outcome measures will be conducted at the 5th month from the baseline measurement by the blinded assessor.

All interventions will be conducted at the Physiotherapy Department at SGH or at the respective TCM clinics. Physiotherapy procedures conducted are part of the standard care for patients with CNLBP, the Tuina procedures that will be conducted for patients with CNLBP are also part of the standard procedures that are being practiced at the TCM clinic.

MOH Registered TCM practitioners will be recruited by SGH to conduct standard Tuina intervention for this study. A room at the Rehabilitation Centre, SGH, will be provided for the Tuina Practitioners to perform Tuina intervention for the subjects or at the respective TCM clinics at the following locations:

1. Zhongjing TCM Clinic, 36 Hamilton Road, Singapore 209206
2. Aequilibrium TCM, 9 King Albert Park, #02-13, KAP Mall, Singapore 598332

The Physiotherapy intervention is provided by Physiotherapists from the Physiotherapy Department, SGH. All interventions for TCM and PT are provided free for all participants and costs borne by the grant provider.

The criteria for selecting service providers for both TCM and Physiotherapy Practitioners are :

1. Must be registered practictioners with MOH.
2. Have at least one year experience treating patients with low back pain conditions.

The outcome measurements consist of

1. VAS - recording the number from the scale from 0 to 10.
2. Spinal flexion and side/lateral flexion range of motion.
3. Oswestry Disability Index
4. 36- item Short Form Survey or SF 36
5. Traditional Chinese Medicine Syndrome Scale

These measurements will be conducted at the baseline, post intervention at 2 months and follow up at 5 months from baseline by the Research Assessor, who is also a study team member but blind to the intervention group. The Assessor will be trained to conduct the measurements for all subjects, by the study team Physiotherapist and TCM practitioner.

Besides these measurements, other data such as patient demographics, social and medical history and other related treatment session reports, such as duration, frequency, satisfaction and adverse events will also be recorded for analysis where appropriate.

Eligibility criteria: Inclusion Criteria:
