BACKGROUND

Walking is widely recognized for its benefits in pain management, disability reduction, and psychological well-being, primarily due to its cost-effectiveness and accessibility. However, comprehensive qualitative insights into the full extent of its benefits remain insufficient. Chronic low back pain (CLBP) significantly impairs daily activities, requiring a multifaceted intervention approach, as advocated by the Biopsychosocial (BPS) model and the International Classification of Functioning, Disability, and Health (ICF) framework.

This systematic review aims to evaluate the perceptions and experiences related to walking among adults suffering from CLBP, understand the barriers and facilitators influencing walking behaviors, analyze behavioral patterns, and examine internal motivators for walking.

This systematic review will include both published and unpublished qualitative studies with participants aged >18 with CLBP persisting > 3 months, where walking is utilized as the primary or secondary intervention. Databases, including PubMed, EBSCO Host, Science Direct, ProQuest, MEDLINE, Epistemonikos, Cochrane Database, and Web of Science, will be searched without language or year restrictions. The screening will involve an independent dual review of the title/abstract and full texts, followed by a critical appraisal. Data extraction and synthesis will employ a meta-aggregation approach, with findings assessed via the ConQual approach.

Synthesized findings will guide evidence-based practice. Recommendations will provide actionable insights to address gaps in qualitative research on walking, promoting a holistic, patient-centered approach to treatment.

OBJECTIVES

To compare the effectiveness of different exercise interventions on improving adiposity-related inflammatory markers of metabolically healthy obese (MHO) adults.

This is a systematic review with meta-analysis of randomized controlled trials (RCTs) and quasi-experimental studies on the effects of exercise interventions in the inflammatory markers of sedentary adults with MHO phenotype. Systematic searches were performed in PubMed, Cochrane, CINAHL, and OVID from January 2021 to January 2022. The included studies were from 2000 to 2021. The inclusion criteria included: a) adults with obese phenotype, b) has physical activity or exercise as intervention, and c) inflammatory markers as outcome measure. Exclusion criteria included: a) pregnant women, b) adults with cardiovascular conditions or taking medications, c) participants having central obesity. The review was registered on PROSPERO (CRD42021249661). Risk of bias (RoB) assessment was performed using Revised Cochrane RoB tool for RCTs, and ROBINS-I tool for quasi-experimental studies. A metaanalysis was performed for inflammatory markers and body composition measurements using random effects model with forest plots presenting mean differences (MD) of outcome measures with 95% CI.

Twenty-one RCTs and seven quasi-experimental studies with 1,117 participants were included in the review. For short-term intervention, aerobic exercises showed an increased trend in IL-6 levels, and both resistance and aerobic exercises reduced TNF-alpha and CRP levels, respectively. For long-term exercises, aerobic exercises showed a significant reduction in CRP (MD= -0.33, 95%CI, -0.57 to -0.09, p=0.006). Long-term concurrent training also showed a significant reduction in TNF-alpha (MD= -2.65, 95%CI, -4.13 to -1.18; p=0.0004). Meta-regression also found no direct association between body weight and fat mass, and changes in inflammatory markers.

Concurrent and aerobic exercises were both effective in reducing pro-inflammatory markers. Concurrent training was more effective in reducing BMI, body fat composition, and CRP compared to aerobic and resistance exercises. Furthermore, middle-aged women benefited from aerobic exercises to reduce IL-6 levels. These results indicate the need for both resistance and aerobic exercise in improving inflammatory levels of the body. This review has limitations in terms of degree of heterogeneity brought by different exercise protocol and assessment of inflammatory markers. More research is needed to identify possible outcome measures that can predict chronic inflammation in MHO people.

Iliotibial band syndrome (ITBS), as an overused injury of the lower extremities, has developed into a common cause of lateral knee pain. At present, the treatment of ITBS includes drug therapy, muscle strength training, physical therapy, and surgical treatment. Among these methods, physical therapy, drug therapy, and surgical treatment can only alleviate the symptoms of patients. As a safe and effective treatment, lower limb muscle strength training can improve patients' muscle strength, correct abnormal gait, and reduce the recurrence rate of the disease by paying attention to the dynamic changes of patients' recovery process. At present, the pathogenesis of ITBS remains unclear, and the treatment methods are not unified. It is necessary to further study the biomechanical factors related to the lower extremities and develop more scientific and comprehensive muscle strength training methods.

OBJECTIVE: To explore application value and effectiveness of virtual reality technology combined with isokinetic muscle strength training in the rehabilitation of patients after anterior cruciate ligament (ACL) reconstruction surgery. METHODS: Forty patients who underwent ACL reconstruction surgery from December 2021 to January 2023 were selected and divided into control group and observation group according to treatment methods, 20 patients in each group. Control group was received routine rehabilitation training combined with isokinetic muscle strength training, including 15 males and 5 females, aged from 17 to 44 years old, with an average of (29.10±8.60) years old. Observation group was performed virtual reality technology combined with isokinetic muscle strength training, including 16 males and 4 females, aged from 17 to 45 years old with an average of (30.95±9.11) years old. Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque between two groups at 12 (before training) and 16 weeks (after training) after surgery were compared. RESULTS: All patients were followed up for 1 to 6 months with an average of (3.30±1.42) months. There were no statistically significant difference in Lysholm knee joint score, peak knee extension peak torque, and peak knee flexion peak torque between two groups (P>0.05) before training. After training, Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque of both groups were improved compared to before training (P<0.05);there were significant difference in Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque between two groups(P<0.05). CONCLUSION The application of virtual reality technology combined with isokinetic muscle strength training could promote recovery of knee joint function and enhance muscle strength in patients after ACL reconstruction surgery in further.

Background: A daily habit of yogic practice or walking, along with an oral hypoglycemic agent (OHA) could be beneficial for better control of type 2 diabetes mellitus (T2DM). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to find out the efficiency of yoga or walking on glycemic control in T2DM. Methodology: The present systematic review and meta-analysis were completed according to the PRISMA guidelines. The risk of bias in included studies was evaluated, by using the revised Cochrane risk-of-bias tool for randomized trials. Meta-analysis was implemented using RevMan software. Forest plots were used to illustrate the study findings and meta-analysis results. Results: Sixteen studies were included in this systematic review, where 1820 participants were allocated to one of the following interventions: yoga, walking, and without any regular exercise (control group). Participants were between 17–75 years of age. Compared to the control group, the yoga group had a significant reduction in fasting blood glucose (FBG) by 31.98 mg/dL (95% CI,–47.93 to –16.03), postprandial blood glucose (PPBG) by 25.59 mg/dL (95% CI, –44.00 to –7.18], glycosylated hemoglobin (HbAlc) by 0.73% (95% CI, –1.24 to -0.22), fasting insulin by 7.19 μIU/mL (95% CI, –12.10 to –2.28), and homeostatic model assessment for insulin resistance (HOMA-IR) by 3.87 (95% CI, –8.40 to -0.66). Compared to the control group, the walking group had a significant reduction in FBG by 12.37 mg/dL (95% CI, –20.06 to –4.68) and HbA1c by 0.35% (95% CI, –0.70 to –0.01). Compared to the walking group, the yoga group had a significant reduction in FBG by 12.07 mg/dL (95% CI, –24.34 to – 0.20), HbA1c by 0.20% (95% CI, –0.37 to –0.04), fasting insulin by 10.06 μIU/mL (95% CI, –23.84 to 3.71) and HOMA-IR by 5.97 (95% CI, –16.92 to 4.99). Conclusions Yoga or walking with OHA has positive effects on glycemic control. For the management of T2DM, yoga has relatively more significant effects on glycemic control than walking.

OBJECTIVE: To observe the effect of acupuncture exercise therapy synchronizing isokinetic muscle strength training on the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy. METHODS: A total of 70 patients after meniscectomy under arthroscopy were randomized into an observation group (35 cases, 2 cases were eliminated， 2 cases dropped off) and a control group (35 cases, 2 cases were eliminated, 1 case dropped off). Acupuncture was applied at Chize (LU 5), Neixiyan (EX-LE 4), Dubi (ST 35),Yanglingquan (GB 34), etc. on the affective side in the two groups. After 30 min, the needles of the knee joint area were withdrew, while the needle at elbow was continuously retained, the observation group was given acupuncture exercise therapy synchronizing isokinetic muscle strength training, and the control group was given conventional acupuncture exercise therapy. The treatment was given once a day, 7-day treatment was taken as one course, and totally 4 courses were required in the two groups. Before and after treatment, the knee joint Lysholm score, the knee joint isokinetic muscle strength flexion/extension ratio (H/Q), joint position sense measurement (JPS) and Hamilton anxiety scale (HAMA) score were compared in the two groups. RESULTS: After treatment, the knee joint Lysholm scores and H/Q were increased compared with those before treatment in the two groups (P<0.001), and the knee joint Lysholm score and H/Q in the observation group were higher than those in the control group (P<0.001); the JPS and HAMA scores were decreased compared with those before treatment in the two groups (P<0.001), the JPS and HAMA score in the observation group were lower than those in the control group (P<0.05). CONCLUSION Acupuncture exercise therapy synchronizing isokinetic muscle strength training can effectively improve the motor function, stability and proprioception of knee joint, as well as the anxiety emotion in patients after meniscectomy under arthroscopy.

OBJECTIVES: To investigate the effect of torso training on unstable surface on lower limb motor function in patients with incomplete spinal cord injury. METHODS: A total of 80 patients with incomplete spinal cord injury caused by thoracolumbar fracture admitted in Ningbo Yinzhou No.2 Hospital from April 2020 to December 2021 were randomly divided into control group and study group, with 40 cases in each group. In addition to routine training, the control group received torso training on stable surface and the study group received torso training on unstable surface. The gait, lower limb muscle strength, balance function, lower limb function, mobility and nerve function of the two groups were compared. RESULTS: After treatment, the stride length, stride frequency and comfortable walking speed improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05). The muscle strength of quadriceps femoris, gluteus maximus, hamstring, anterior tibialis and gastrocnemius were improved in the two groups (all P<0.05), and the improvements in study group were more significant (all P<0.05); the total trajectories of static eye opening and static eye closing gravity center movement in the two groups were significantly shorter (all P<0.05), and the improvements in the study group were more significant (all P<0.05). The dynamic stability limit range and the American Spinal Injury Association (ASIA) lower extremity motor score, Berg balance scale, modified Barthel index scale in the two groups were significantly higher (all P<0.05), and these scores in study group were significantly higher than those in the control group (all P<0.05). Both groups showed a significant improvement in ASIA grade (all P<0.05), and the improvement in the study group was significantly better (P<0.05). CONCLUSIONS Torso training on unstable surface can effectively improve the gait and lower limb muscle strength of patients with incomplete spinal cord injury and improve the lower limb motor function.

A protective device was designed that can be worn on the elderly, which consists of protective airbag, control box and protective mechanism. The combined acceleration, combined angular velocity and human posture angle are selected as the parameters to determine the fall, and the threshold algorithm and SVM algorithm are used to detect the fall. The protective mechanism is an inflatable device based on CO₂ compressed air cylinder, and the equal-width cam structure is applied to its transmission part to improve the puncture efficiency of the compressed gas cylinder. A fall experiment was designed to obtain the combined acceleration and angular velocity eigenvalues of fall actions (forward fall, backward fall and lateral fall) and daily activities (sitting-standing, walking, jogging and walking up and down stairs), showing that the specificity and sensitivity of the protection module reached 92.1% and 84.4% respectively, which verified the feasibility of the fall protection device.

An in-depth understanding of the mechanism of lower extremity muscle coordination during walking is the key to improving the efficacy of gait rehabilitation in patients with neuromuscular dysfunction. This paper investigates the effect of changes in walking speed on lower extremity muscle synergy patterns and muscle functional networks. Eight healthy subjects were recruited to perform walking tasks on a treadmill at three different speeds, and the surface electromyographic signals (sEMG) of eight muscles of the right lower limb were collected synchronously. The non-negative matrix factorization (NNMF) method was used to extract muscle synergy patterns, the mutual information (MI) method was used to construct the alpha frequency band (8-13 Hz), beta frequency band (14-30 Hz) and gamma frequency band (31-60 Hz) muscle functional network, and complex network analysis methods were introduced to quantify the differences between different networks. Muscle synergy analysis extracted 5 muscle synergy patterns, and changes in walking speed did not change the number of muscle synergy, but resulted in changes in muscle weights. Muscle network analysis found that at the same speed, high-frequency bands have lower global efficiency and clustering coefficients. As walking speed increased, the strength of connections between local muscles also increased. The results show that there are different muscle synergy patterns and muscle function networks in different walking speeds. This study provides a new perspective for exploring the mechanism of muscle coordination at different walking speeds, and is expected to provide theoretical support for the evaluation of gait function in patients with neuromuscular dysfunction.
