Effect of two suspension training programs on pain and musculoskeletal function in chronic low back pain: study protocol.

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.

Low back pain is one of the most common symptoms encountered in everyday life. One of the indicated treatments is the practice of exercises; among them, we can mention the training that uses suspended tapes, called suspension training. The aim of this study is to compare the effects of two suspension training protocols on individuals with chronic low back pain. Methodology: women aged 18 to 60 years with low back pain for more than 12 weeks will be selected. Pre- and post-treatment pain level, trunk and leg motion range and flexibility, functional capacity, biopsychosocial factors, fears and beliefs, pain catastrophizing scale, trunk and leg muscle strength and endurance, depression and anxiety, self-perception and treatment satisfaction will be assessed. The training will take place twice a week, for 60 min, for 3 months. It is expected to verify pain reduction and functionality improvement in both groups and evaluate the best training protocol.

Immediate analgesic effect of two modes of short-wave diathermy application in chronic low back pain: study protocol for a randomized controlled trial.

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).

Lay abstract Aim : Low back pain is one of the main health problems in the world. Short-wave diathermy (SWD) is a physiotherapy device that can be used to treat low back pain, but its scientific effectiveness is uncertain. Objective: To evaluate and compare the effects of pain reduction immediately after application of the device (SWD) in two different application methods in individuals with chronic low back pain. Materials & methods: Clinical trial in which 159 individuals will be selected and randomly allocated into three groups: pulsed short-wave diathermy group, n = 53; continuous short-wave diathermy group, n = 53 and placebo group, n = 53. The technique will only be applied once for 30 min. The main result analyzed will be pain. Other results that will also be evaluated are perception of global improvement and treatment satisfaction, functionality (ability to perform daily tasks), leg strength and trunk mobility. It will also be verified the presence of depression, anxiety, psychological and social factors that may influence the response to treatment. Individuals will be evaluated before the first session, immediately after the application of the device and 1 week later. Conclusion: It is expected to verify the decrease in pain soon after the application of the device in the chronic low back pain and find out if there is any difference in this outcome according to the application method.
