Abstract Background Structural impairment of the lumbar multifidus muscle, such as reduced cross-sectional area, is evident among individuals with chronic low back pain. Real-time ultrasound imaging (RUSI) biofeedback has been reported to improve preferential activation of as well as retention in the ability to activate the lumbar multifidus muscle during lumbar stabilization exercises (LSE). However, evidence of the effectiveness of this treatment approach in individuals with non-specific chronic low back pain (NCLBP) is still limited. The purpose of this study is, therefore, to determine the effectiveness of LSE with RUSI biofeedback on lumbar multifidus muscle cross-sectional area in individuals with NCLBP. Methods/Design This study is a prospective, single-center, assessor-blind, three-arm, parallel randomized controlled trial to be conducted at National Orthopedic Hospital, Kano State, Nigeria. Ninety individuals with NCLBP will be randomized in a 1:1:1: ratio to receive LSE, LSE with RUSI biofeedback, or minimal intervention. All participants will receive treatment twice weekly for 8 weeks. The primary outcome will be the lumbar multifidus muscle cross-sectional area. The secondary outcomes will include pain (Numerical Pain Rating Scale), functional disability (Roland–Morris Disability Questionnaire), and quality of life (12-Item Short-Form Health Survey). All outcomes will be assessed at baseline, 8 weeks post-intervention,  and 3 months follow-up. Discussion To our knowledge, this study will be the first powered randomized controlled trial to compare the effectiveness of LSE training with and without RUSI biofeedback in individuals with NCLBP. The outcome of the study may provide evidence for the effectiveness of LSE with RUSI biofeedback on enhancing the recovery of the lumbar multifidus muscle in individuals with NCLBP.

Abstract Background: Impairments in the lumbar multifidus muscle such as reduced muscle thickness and fat infiltrations are evident in individuals with low back pain. Lumbar stabilization exercises (LSE) with real-time ultrasound imaging (RUSI) biofeedback has been reported to improve preferential activation of as well as retention in the ability to activate of the lumbar multifidus muscle, thus enhancing recovery. However, the effects of using this treatment approach in individuals with nonspecific chronic low back pain (NCLBP) seemed not to have widely reported. The purpose of this study is, therefore, to investigate the effects of LSE with RUSI biofeedback on lumbar multifidus muscle cross-sectional area in individuals with NCLBP patients. Method: This study is a prospective, single-center, assessor-blind three-arm, randomized controlled to be conducted at National Orthopedic Hospital, Kano State, Nigeria. Ninety-one individuals with NCLBP will be randomly assigned into one of the three treatment groups of equal sample size (n = 30); LSE group, LSE with RUSI biofeedback group, or control (minimal intervention). The participants in the LSE and LSE with RUSI biofeedback group will also receive the same intervention as the control group. All participants will receive treatment twice weekly for 8 weeks. The primary outcome will be lumbar multifidus muscles cross-sectional area while the secondary outcomes will be pain, functional disability and quality of life. All outcomes will be assessed at baseline, and at 8 weeks and 3 months post-intervention.Discussion: The outcome of the study may support the evidence for the effectiveness of LSE with RUSI biofeedback in the rehabilitation of individuals with NCLBP. It may also provide a rationale for the physiotherapists to make use of diagnostic ultrasound as a feedback mechanism in enhancing the performance and retention of LSE program as well as monitoring the patient’s recovery.Trial registration: Pan African Clinical Trials Registry, (PACTR201801002980602), Registered on 16 January 2018.

BACKGROUND: The multifidus muscle is located near the spine and controls the erection of the spine and stabilization during movements of the spine and extremities, and assists in all other spinal movements. Differences in paraspinal muscles between sides and levels, particularly in he multifidus, have been proposed as possible indicators of low back pain or spinal pathology. OBJECTIVE: This study aims to examine the cross-sectional area of the lumbar multifidus muscle at L4-L5 vertebral levels on ultrasound images of athletes in Olympic-style weightlifting, judo athletes and sedentary individuals. METHODS: This study included asymptomatic male athletes (athletes in Olympic-style weightlifting, n= 17, age: 19.24 ± 1.88, judo athletes, n= 17, age: 19.18 ± 1.23) and sedentary individuals (n= 17, age: 19.88 ± 1.31). The cross-sectional area of lumbar multifidus muscles was assessed bilaterally at the L4-L5 segments level in prone and using ultrasound imaging. RESULTS: Lumbar multifidus muscle cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes were larger than those of sedentary individuals (p< 0.004). No asymmetric development was observed in cross-sectional areas of right-left lumbar multifidus muscle at L4-L5 levels of athletes in Olympic-style weightlifting and sedentary individuals (p> 0.008). The cross-sectional areas of the right and left lumbar multifidus muscle at L5 segment of individuals in judo athletes was found to be asymmetrical (p< 0.008). CONCLUSION: Our study shows that the cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes are larger than that of sedentary individuals. The difference in the cross-sectional area of the lumbar multifidus muscle of athlete and sedentary groups might be said to result from hypertrophic effect of trainings of these athletes on the cross-sectional area of the lumbar multifidus muscle.
