Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group:
In addition to usual care, participants will receive LLLA from a licensed acupuncturist at ECU Acupuncture Research Clinic. 10-20 minutes per session, three times a week for two weeks. The parameters of 3B Laser Pen (200mW) used for the intervention are wavelength of 808 nm in continuous wave mode, each pressure point receives 20 seconds of energy (4J) with 5 minutes being the maximum treatment time (60 J). At the end of two weeks receiving the therapy, participants will receive an online link to complete the post-intervention questionnaires.

Outcomes
Primary outcome [1] 326449 0
The primary outcome for this study is feasibility of the two weeks LLLA therapy for office workers with SNP. Feasibility will be assessed by measuring: 1) recruitment and completion rates (No. of referred, No. of eligible, No. of enrolled, No. of withdrawals, trial recruitment rate, and trial completion rate), 2) patient safety (No. and severity of adverse events), and 3) treatment adherence (No. of completed sessions and missed sessions). Participants’ motivation and challenges to participation, withdrawal, missed sessions and non-compliance to intervention will be investigated, as will their attitude, and experience in participating the trial.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All potential participants will be provided with an online information sheet and consent form outlining what will be involved in the trial. People who gave consent will complete a set of online questions. The recruitment will continue until the required number is reached.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will then be randomised via survey software (Qualtrics) to one of the two groups by a statistician who is blinded to the identity of the individuals.
Masking / blinding

Other design features
Participants will be randomly allocated to one of the two groups:
1. in addition to usual care, receive six laser acupuncture treatment sessions from a licensed acupuncturist at ECU Acupuncture Research Clinic. Or
2. receive NO treatment but usual care over two weeks’ trial time

Statistical methods / analysis
Analysis of the pre- post-intervention data will consist of Generalised Linear Mixed Modelling through R software to detect effects of the intervention versus the control groups.

Summary
Brief summary
Shoulder and neck pain (SNP) are common and burdensome conditions in office workers with a high prevalence. It is a serious public health problem and has a significant detrimental impact on one’s quality of life, physical functioning, economic structure, families, employers and health care system.
Lengthened working hours on the computer, prolonged sitting position, and static postures are the most contributing factors, and medication and physiotherapy were the most common intervention strategies that people chose to manage their pain.
The low-level laser therapy (LLLT), also known as cold laser, photobiomodulation, applies specific wavelengths and low power density, has been shown to be an additional option in the SNP management to relive pain and re-establish quality of life. LLLT can promotes analgesic and anti-inflammatory effects, improve blood circulation, boosts immunity and speeds up wound healing, with no reported adverse effects and well received by many patients.
Low-level laser acupuncture (LLLA), is one of the recent technological developments (e.g., electroacupuncture) in the practice of acupuncture, which integrate the cutting-edge laser technology and thousands of years old TCM modality. Instead of the needle stimulation on the acupuncture points, low intensity non thermal laser irradiation is applied to elicit the cellular level’s physiologic effects with sufficient energy. It is, therefore, non-invasive, painless, non-infectious and safe to use. LLLA has become increasingly attractive for patients with needle phobias, older people and children.
Several studies demonstrated that LLLA is a promising modality in pain management. However, there is no consolidated evidence for LLLA in managing shoulders and neck pain, and more studies in this field are required to provide updated evidence. Therefore, this study aims to provide compelling evidence of the feasibility and therapeutic efficacy of LLLA for office workers with SNP.
We anticipate, based on past research, the LLLA we will provide may be helpful in reducing levels of SNP. We hope that the results of our research can be used to inform our knowledge about how to better manage SNP that many office workers are suffering.
