Clinical Trial Summary

The aim of this randomized clinical trial will be to compare the efficacy between acupuncture and laser acupuncture on pain and disability in people with chronic nonspecific low back pain .

Description:

Forty-four patients with chronic cnLBP of more than three months duration will be randomly allocated to two groups: acupuncture group (ACP) (n = 22) and laser acupuncture group (LACP) (n = 22).Interventions will last one hour, and will happen twice a week for 5 weeks. The primary clinical outcomes will be pain intensity (11-point numeric pain rating scale) as measured and functional disability (Oswestry Disability Index).The secondary outcomes will be the Pain Catastrophizing Scale, Patient-Specific Functional Scale and fingertip-to-floor test. Evaluations will be performed before and after the first session, after 5 weeks of treatment, and three months after randomization (follow-up). The findings will be analyzed statistically considering a 5% significance level (p ≤ 0.05).

Intervention

Other:
• Acupuncture
Treatment with ACP will be performed by inserting sterile acupuncture needles 0.25 x 13 mm into the acupoints BL23 (Shenshu), BL25 (Dachangshu), BL40 (Weizhong), BL62 (Qixue), SI3 (Houxi) and Jiaji , for the treatment of chronic non-specific low back pain. Interventions will last one hour, and will happen twice a week for 5 weeks. In order to increase the effectiveness of blinding for both groups, in this study the model was adopted: "combined simulated control". In this case, Sham acupuncture points will be used to simulate the treatment, as follows: i) Arms: 3 cm above the lateral epicondyle of the elbow, ii) Lumbar spine: Iliac crest on the same line as the greater trochanter of the femur. Thus, in the ACP group, the placebo LACP (without dosemetry) will be applied to these 4 points together with the real treatment.
• Laser acupuncture
The use of LACP (808 nm wavelength, 100 mW, energy 6 J per acp point), on acupoints BL23 (Shenshu), BL25 (Dachangshu), BL40 (Weizhong), BL62 (Qixue), SI3 (Houxi) and Jiaji will be used as a treatment for nonspecific chronic low back pain. Interventions will last one hour, and will happen twice a week for 5 weeks. Sham acupuncture points will be used to simulate the treatment, as follows: i) Arms: 3 cm above the lateral epicondyle of the elbow, ii) Lumbar spine: Iliac crest on the same line as the greater trochanter of the femur. These sham points will be inserted superficially so that the depth is sufficient to keep them fixed during the experiment, without individuals reporting the "dequi".

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain intensity	The Numeric Pain Rating Scale will be used to determine the level of pain intensity perceived by the patient using an 11-point scale on which 0 represents the absence of pain and 10 represents the worst pain imaginable.	3 months
Primary	Functional disability	The Oswestry Disability Index will be used to determine the functional disability of participants. Questionnaire examines perceived level of disability in 10 everyday activities of daily living. The 6 statements are scored from 0 to 5 with the first statement scoring 0 through to the last at 5. Interpretation of Scores; 0% to 20% - minimal disability; 21%-40% - moderate disability; 41%-60%- severe disability; 61%-80%- crippled; 81%-100%: These patients are either bed-bound or exaggerating their symptoms.	3 months
Secondary	Pain Catastrophizing	The Pain Catastrophizing Scale will be used to assess catastrophic thinking related to pain. 13 items rated on 5-point Likert scales, from (0) not at all to (4) all the time. Higher score indicates higher level of catastrophizing; Item scores are summed into a total score (PCS-T) and three subscale scores: Rumination: Items 8, 9, 10, and 11 (response: 0-16 points); Magnification: Items 6, 7, 13 (response: 0-12 points); Helplessness: Items 1, 2, 3, 4, 5, and 12 (response: 0-24points) A total score above 30 indicates clinically relevant level of catastrophizing	3 months
Secondary	Functional independence.	The Patient-Specific Functional Scale will be used to assess the participant's levels of functional independence. Patients are asked to rate (on an 11-point scale) the current level of difficulty associated with each activity. Following the intervention, patients are asked again to rate the activities previously identified (and are given the chance to nominate new problematic activities that might have arisen during that time).; "0" represents "unable to perform" and "10" represents "able to perform at prior level"	3 months
Secondary	Mobility of spine and pelvis	The fingertip-to-floor test will be used to evaluate the mobility of both the whole spine and the pelvis in the overall motion of bending forward.; If the fingertip-to-floor test is "0"cm or the patient is able to place their palms to the floor with no pain, a different outcome measure should be considered.	3 months
