The Effect of Swiss Ball Stabilization Exercise on Pain and Bone Mineral Density of Patients with Chronic Low Back Pain

Efficacy of specific exercises in general population with non-specific low back pain: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Localized exercises are employed to activate, train, or restore the function of particular muscles and they are usually considered as part of treating individuals suffering low back pain. So, this systematic review and meta-analysis aimed to assess the efficacy of specific exercises in general population with non-specific low back pain (LBP).

METHODS

We conducted electronic searches in MEDLINE/PubMed, Scopus, Web of Science (WoS), and Google scholar from January 1990 to June 2021. Initially, 47,740 records were identified. Following the removal of duplicates, 32,138 records were left. After reviewing titles and abstracts, 262 papers were chosen for thorough assessment. Among these, 208 studies were excluded, resulting in 54 trials meeting the inclusion criteria for this study. Additionally, 46 of these trials were randomized controlled trials and were further evaluated for the meta-analysis. We included trials investigating the effectiveness of exercise therapy, including isometric activation of deep trunk muscles, strengthening exercises, stabilization exercises, stretching exercises, and proprioceptive neuromuscular facilitation exercises (PNF) in LBP patients. The primary outcome was pain intensity, measured using tools such as the visual analogue scale (VAS) and numeric pain rating scale (NPRS). The secondary outcome was disability, assessed through instruments such as the Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI). The quality of the eligible studies was assessed using the Verhagen tool, and the level of evidence was evaluated using the GRADE approach.

RESULTS

Based on the Verhagen tool, 46 trials (85.2%) were categorized as having low methodological quality, while 8 studies (14.8%) were considered to have medium methodological quality. The meta-analysis indicated a small efficacy in favor of isometric activation of deep trunk muscles (-0.37, 95% CI: -0.88 to 0.13), a moderate efficacy in favor of stabilization exercises (-0.53, 95% CI: -1.13 to 0.08), and a large efficacy in favor of PNF exercises (-0.91, 95% CI: -1.62 to -0.2) for reducing pain intensity as assessed by VAS or NPRS tools. Moreover, the meta-analysis revealed a moderate efficacy for isometric activation of deep trunk muscles (-0.61, CI: -1.02 to -0.19), and a large efficacy for PNF exercises (-1.26, 95% CI: -1.81 to -0.72) in improving disability, assessed using RMDQ or ODI questionnaires. The level of certainty in the evidence, as determined by the GRADE approach, was very low to low.

CONCLUSION

These findings emphasize the importance of incorporating localized therapeutic exercises as a fundamental aspect of managing non-specific LBP. Clinicians should consider utilizing localized therapeutic exercise tailored to individual patient needs. Furthermore, further research investigating optimal exercise therapy, optimal dose of the exercises, durations, and long-term adherence is warranted to enhance the precision and efficacy of exercise-based interventions for non-specific LBP.

Radiological (Magnetic Resonance Image and Ultrasound) and biochemical effects of virtual reality training on balance training in football players with chronic low back pain: A randomized controlled study

BACKGROUND

Virtual reality training is commonly used for balance problems in neurological conditions with the use of visual and auditory biofeedback. The knowledge about the effective implementation of this training in chronic low back pain is lacking.

OBJECTIVE

The objective of this study is to find the radiological and biochemical effects of virtual reality training in football players with chronic low back pain.

METHODS

A randomized, single-blinded controlled study was conducted on 36 participants. The first group received virtual reality training (VRT; n= 12), the second group received combined physical rehabilitation (CPR; n= 12), and the third group (control group; n= 12) received conventional training exercises for four weeks. Radiological (muscle cross-sectional area and muscle thickness) and biochemical (CRP, TNF-α, IL-2, IL-4, IL-6) values were measured at baseline and after four weeks.

RESULTS

Four weeks following training, the VRT group showed more significant changes in the muscle cross-sectional area than the CPR and control groups (p⩽ 0.001). Biochemical measures such as CRP, TNF-α, IL-2, IL-4, and IL-6 also showed significant improvement in the VRT group compared to the other two groups (p⩽ 0.001).

CONCLUSION

The results show that virtual reality training has positive effects on the radiological and biochemical aspects in university football players with chronic low back pain.

Short-Term Psychological and Hormonal Effects of Virtual Reality Training on Chronic Low Back Pain in Soccer Players

OBJECTIVE

To find the short-term psychological and hormonal effects of virtual reality training on chronic low back pain in American soccer players.

DESIGN, SETTING, PARTICIPANTS

The 3-block random sampling method was used on 54 university American soccer players with chronic low back pain, and they were allocated into 3 groups: virtual reality training (VRT; n = 18), combined physical rehabilitation (n = 18), and control (n = 18) groups at University Hospital. They underwent different balance training exercises for 4 weeks. The participants and the therapist who is assessing the outcomes were blinded. Psychological (pain intensity and kinesiophobia) and hormonal (glucose, insulin, Homeostatic Model Assessment of Insulin Resistance, growth hormone, prolactin, adrenocorticotropic hormone, and cortisol) values were measured at baseline, after 4 weeks, and after 6 months.

RESULTS

The baseline demographic, psychological, and hormonal data between the VRT, combined physical rehabilitation, and control groups show no statistical difference (P ≥ .05). Four weeks following training, the VRT group shows more significant changes in pain intensity and kinesiophobia than the combined physical rehabilitation and control groups (P < .001), and the improvement was noted in the 6-month follow-up. All the hormonal variables (glucose, insulin, growth hormone, prolactin, adrenocorticotropic hormone, and cortisol) show significant changes at 4-week training (P < .001), except for the Homeostatic Model Assessment of Insulin Resistance (P = .075) between the 3 groups. At 6-month follow-up glucose, prolactin, adrenocorticotropic hormone, and cortisol show more significant difference in the VRT group than the other 2 groups (P < .001). At the same time, insulin (P = .694), Homeostatic Model Assessment of Insulin Resistance (P = .272), and growth hormone (P = .145) failed to show significant changes between the groups.

CONCLUSION

Training through virtual reality is an effective treatment program when compared with conventional exercise training programs from a psychological and hormonal analysis perspective in American soccer players with chronic low back pain.

Isokinetic training - its radiographic and inflammatory effects on chronic low back pain: A randomized controlled trial

BACKGROUND

Isokinetic training (IKT) and core stabilization training (CST) are commonly used for balance training in musculoskeletal conditions. The knowledge about the effective implementation of these training protocols on radiological and biochemical effects in university football players with chronic low back pain (LBP) is lacking.

OBJECTIVE

To find and compare the effects of isokinetic training and CST on radiological and biochemical effects in university football players with chronic LBP.

DESIGN

Randomized, double-blinded controlled study.

SETTING

University hospital.

PARTICIPANTS

60 LBP participants were randomized into isokinetic group (IKT; n = 20), core stabilization group (CST; n = 20) and the control group (n = 20) and received respective exercises for 4 weeks.

OUTCOME MEASURES

Radiological (muscle cross sectional area & muscle thickness) and biochemical (C-reactive protein, tumor necrosis factor -α, interleukin [IL]-2, IL-4, IL-6) values were measured at baseline and after 4 weeks (immediate effect).

RESULTS

The reports of the IKT, CST and control group were compared between the groups. Four weeks following training IKT group shows more significant changes in muscle cross sectional area (Psoas Major, Quadratus Lumborum, Multifidus and Erector Spinae muscles) and muscle thickness (Multifidus) than CST and control groups (p < 0.001). Biochemical measures such as C-reactive protein, tumor necrosis factor -α, IL-2, IL-4 and IL-6 also show significant improvement in IKT group than the other 2 groups (P < .001).

CONCLUSION

Training through Isokinetic is an effective treatment program than conventional exercise programs in the aspect of radiological and biochemical analysis in university football players with chronic LBP, which may also help to prevent further injury. The present study can be used to improve the physical therapist's knowledge and clinical decision skills on LBP in football players.

Effects of muscle extension strength exercise on trunk muscle strength and stability of patients with lumbar herniated nucleus pulposus

[Purpose] The purpose of this study was to provide the data for constructing an integrated exercise program to help restore muscle strength and stability through extension strength exercise in adult females with lumbar disc herniation. [Subjects and Methods] An 8-week exercise program for lumbar muscle extension strength and stabilization was performed by 26 females older than 20 with lumbar disc herniation findings. [Results] Significant differences were found in lumbar extension muscle strength at every angle of lumbar flexion after participation in the 8-week stabilization exercise program; but there was no significant difference in the weight distribution index. [Conclusion] An integrated exercise program aiming to strengthen lumbar spine muscles, reduce pain and stabilize the trunk can help to maintain muscle strength and balance. In addition, improvement in extension strength is expected to be helpful in daily life by securing the range of joint motion and improving the strength and stability.
