The aim of this study is to compare the effects of two suspension training (ST) protocols on pain and musculoskeletal function in women with chronic low back pain (CLBP). The study will be randomized, controlled, blinded clinical trial. Women aged 18-60 years who present CLBP will be selected. They will be randomized into three groups: STG1, which will carry out the program with difficulty progression in the exercises; STG2, in which the progression will be made by increasing the number of sets; and control group. STG1 and STG2 will perform the training two-times a week for 60 min for 12 weeks. It is expected that ST will effectively reduce pain and improve functionality in CLBP and that the best protocol will be verified. Clinical Trial Registration : RBR-10rv3fqt.

The aim of this study is to evaluate and compare the immediate analgesic effects of two applications of short-wave diathermy (SWD) in individuals with chronic low back pain. Randomized, controlled, double-blind clinical trial. A total of 159 participants with chronic low back pain will be randomized in three groups: pulsed mode SWD, continuous mode SWD and placebo. SWD will be applied only once for 30 min. The primary outcomes: intensity and quality of pain. Secondary outcomes: depression and anxiety; perception of global improvement; patient satisfaction; disability and influence of psychosocial factors, strength of the lower limbs and the mobility of the posterior chain. Patients will be evaluated before and after the session and 1 week after. Trial registration number: RBR-2k58f5h Brazilian Registry of Clinical Trials (ReBEC).

Background: Low back pain (LBP) is the most frequent complaint in clinical practice. Electroacupuncture treatment may be effective; however, the supporting evidence is still limited, especially in older adults., Objective: The current study is a randomized controlled trial that aims to evaluate the clinical efficacy of electroacupuncture in older adults with LBP., Methods: A five-arm randomized controlled trial with patients and evaluators blinded to the group allocation. A total of 125 participants with non-specific LBP will be randomly assigned into one of five groups: three electroacupuncture groups (low, high, and alternating frequency); one control group; and one placebo group. The electroacupuncture will be applied twice a week (30 min per session) for five weeks. The primary clinical outcome measure will be pain intensity. The secondary outcomes include: quality of pain; physical functioning; perceived overall effect; emotional functionality; patient satisfaction; and psychosocial factors. Patients will be evaluated before the first session, immediately after the last, and followed up after six and 12 months to check the medium- and long-term effects., Discussion: Although electroacupuncture is increasingly used to treat LBP, there is no guidance regarding the parameters used, which leads to inconsistent results. Thus, the effect of electroacupuncture (EA) on LBP remains controversial and requires more studies, especially in the older adult population., Conclusion: This is the first randomized controlled trial to evaluate the efficacy of different frequencies of electroacupuncture for treating chronic LBP in older adults. This study will provide evidence on the effectiveness of electroacupuncture as an alternative treatment method for LBP and will entail wider debate about an appropriate acupuncture intervention in this population., Trial Registration: Clinicaltrials.gov, NCT03802045.
