Background In recent years, the incidence of non-specific low back pain has been increasing. The duration of conventional treatment is short, and the symptoms tend to rebound, which has a great impact on the body and mind of patients. Objective To investigate the effectiveness of backward walking based on anti-gravity treadmill training system combined with conventional low back core training on patients with non-specific low back pain. Methods A total of 40 patients with non-specific low back pain admitted to the Rehabilitation Department of Zhongshan Hospital, Fudan University from July to December 2022 were divided into the experimental group (20 cases) and control group (20 cases) according to the random number table method. The control group received conventional low back core training, and the experimental group received backward walking based on anti-gravity treadmill training system on the basis of the control group. The Oswestry Disability Index (ODI), Visual Analogue Scale (VAS) and Back Pain Classification Scale (BPS) of the 2 groups were evaluated before and 4 weeks after treatment, respectively. Results There was no significant difference in ODI, VAS and BPS scores between the two groups before treatment (P>0.05) ; after 4 weeks of treatment, ODI, VAS and BPS scores of the 2 groups were decreased, and ODI, VAS and BPS scores of the experimental group were significantly lower than those of the control group (P

BACKGROUND: Backward walking is mainly considered to improve the symptoms of patients with knee osteoarthritis, which is used for rehabilitation and adjuvant treatment of knee osteoarthritis, but there is no evidence for evidence-based medicine. OBJECTIVE: To systematically review and quantify the evidence for the effect of backward walking on knee osteoarthritis in order to clarify the effect of backward walking on knee osteoarthritis. METHODS: PubMed, CINAHL, EMBASE, CNKI, CBM, WanFang and VIP were searched for relevant literature. After randomized controlled trials were screened, a meta-analysis was used to evaluate the effectiveness of backward walking on knee osteoarthritis. A total of 7 articles involving 231 patients were included in the result analysis. RESULTS AND CONCLUSION: Meta-analysis found that: compared with conventional treatment alone, the combination of conventional treatment with backward walking was better in pain relief [mean difference (MD)=-1.05, 95% confidence interval (CI) (-1.46, -0.63), P= 0.000 1], improving knee joint function [standardized mean difference (SMD)=-0.98, 95% CI (-1.33, -0.64), P < 0.000 01], enhancing quadriceps strength [SMD=1.07, 95% CI (0.52, 1.63), P=0.000 2] and improving timed up to go performance [MD=-0.41, 95% CI (-0.67, 0.16), P=0.001]. However, there was no significant difference in the WOMAC score after backward and forward walking [SMD=-0.43, 95% CI (-0.94, -0.08), P=0.10]. Meta-analysis results indicate that the combination of backward walking with conventional treatment has better clinical efficacy than conventional treatment alone for knee osteoarthritis patients. However, on the basis of conventional treatment, backward walking has comparable effects on WOMAC scores as compared with forward walking, which needs further large-sample high-quality randomized controlled trials to be verified.

BACKGROUND: Clinical conservative treatment can easily lead to the recurrence of lumbar disc herniation. Backward walking is a popular rehabilitation exercise method for the treatment of lumbar disc herniation. After clinical guidance treatment, patients walk backwards and follow up statistics, confirming that walking backwards is an effective rehabilitation exercise therapy. OBJECTIVE: Based on biomechanics, the significance of backward walking for lumbar rehabilitation was explored by finite element analysis. METHODS: The three-dimensional model of lumbar spine was established based on CT images, and then the mechanical conditions of lumbar spine were simulated. The finite element method was used to examine the role of backward walking in the treatment of lumbar disc herniation from the mechanical point of view. RESULTS AND CONCLUSION: (1) The displacement of L1-L2 intervertebral disc was only 1/2 of that of the gait, and the stress of the intervertebral disc was greatly reduced when walking backwards. (2) The stress of L1-L2 intervertebral disc during gait progression was 2.35 times as much as that during walking backwards. (3) Therefore, the changes of stress and displacement of lumbar spine and intervertebral disc are smaller than that of normal gait, which reduces the pressure on nucleus pulposus and helps the recovery of patients with lumbar disc herniation.

[Purpose] The purpose of this study was to investigate the EMG patterns and the integrated EMG of forward walking and backward walking at four different walking speeds. [Subjects] Twelve healthy subjects with a mean age of 21.8 years participated in this study. [Method] The surface EMGs of eight muscles (gluteus maximus, gluteus medius, biceps femoris, rectus femoris, vastus medialis, gastrocnemius of lateral head, tibialis anterior, and soleus) were measured at walking speeds of 20 m/min, 40 m/min, 60 m/min, and 80 m/min. [Result] There was no similarity of the EMG pattern of forward walking and backward walking in any muscle at any speed. The amount of muscle activity in backward walking was bigger than that of forward walking in many muscles. In addition, the integrated EMG increased with an increase in walking speed regardless of the style walking. [Conclusion] The EMG pattern of backward walking is different from forward walking. Regardless of the walking style, and increase in walking speed increases the integrated EMG. [ABSTRACT FROM AUTHOR]
