Background: Chronic back pains are progressively disabling working individuals, including 60–80% of the general population, for which their diagnosis is challenging to healthcare workers worldwide, thereby becoming a burden to nations. Purpose: The study aimed to investigate the efficacy of core strengthening exercise (CSE) and intensive dynamic back exercise (IDBE) on pain, core muscle endurance, and functional disability in patients with chronic non-specific low back pain (LBP). Methods: The study was based on a three-arm parallel-group randomized control design. Forty-five participants with chronic non-specific LBP were recruited and randomly divided into the CSE, IDBE, and Control groups. The CSE and IDBE groups received CSE and IDBE, respectively. However, the Control group received no intervention. Numeric pain rating scale, Oswestry Disability Index, core flexors, extensors, and side bridge tests assessed pain intensity, functional disability, and endurance of core muscles. Outcome scores for the dependent variables were collected at baseline (pre-intervention) and six-week post-intervention. There were no follow-up measurements in this study. A one-way multivariate analysis of covariance (MANCOVA) was used to analyze the intervention effects on the outcomes within groups and between groups, respectively; keeping the significance-level alpha at 95%, i.e., p < 0.05. A univariate F-test was performed to observe the superiority of one treatment over another. Pearson’s correlation coefficient test was conducted to determine a relation between the dependent variables. In all statistical analyses, the level of significance α was kept at 0.05. Results: All forty-five out of sixty-three participants with chronic non-specific low back pain (male, 32 and female, 23; average age, 20.24 ± 1.46 years; average pain duration, 19.6 ± 5.42 weeks) completed the study and their data were analyzed. The MANCOVA test showed a significant difference between the treatment groups on the combined multiple endurance tests for the core muscles (flexors, extensors, side bridge tests to the right and left), Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) scores after controlling for baseline scores of all the dependent variables: F (6, 12) = 23.381; p < 0.05; Wilks’ Λ = 0.033; partial η² = 0.819. A post hoc pair-wise comparison followed by a univariate F-test indicated that a significant improvement was found between the CSE vs. IDBE vs. Control groups on the post-test scores of all the dependent variables except VAS and EET (CSE vs. IDBE only). A Pearson’s correlation coefficient test revealed a notable relation between the dependent variables. Conclusions: The experimental group CSE was found to be more effective than IDBE on improving functional disability, cores’ flexors, and side bridges’ endurance tests than IDBE. The magnitude of this improvement exceeded the minimal clinically important difference (MCID), suggesting a clinically relevant enhancement in functional disability, core flexors, and side bridge endurance for participants engaged in CSE. However, CSE vs. IDBE revealed non-significant differences on reducing pain and core extensors’ endurance. The absence of statistically significant differences suggests that the observed changes did not exceed the established MCID for pain intensity and core extensors’ endurance. In addition, partial eta-squared value revealed the superiority of CSE over IDBE and Control groups. This suggests that the observed differences between the two interventions are not only statistically significant, but also clinically relevant, surpassing the established MCID.

Chronic low back pain (CLBP) substantially impacts quality of life through a multifarious interplay of physical and psychological elements. A comprehensive understanding of this relationship is imperative for developing effective treatment strategies. This study recruited 64 participants (35 males and 29 females) experiencing chronic low back pain to explore the associations between psychological factors, muscle endurance, and functional impairments. The study was conducted over six months in an outpatient department and a rehabilitation unit. The study utilized established outcome measures, such as the Biering-Sorensen Test and the Roland Morris Disability Questionnaire, and psychological variants as the core dependent variables, including the Beck Depression Inventory (BDI), STAI questionnaire, the FABQ-PA, and the Pain Catastrophizing Scale (PCS). The findings uncovered pronounced gender disparities, with females exhibiting elevated levels of depression (BDI: 27.68 ± 9.43, p < 0.001) and anxiety (STAI: 42.34 ± 8.94, p < 0.001) and diminished muscle endurance (130.47 ± 30.56 sec, p = 0.001). These revelations are congruent with the prevailing literature, emphasizing the need for gender-sensitive and personalized interventions. Bivariate correlations presented robust associations between psychological distress and decreased muscle endurance (r values ranging from −0.82 to −0.88, p < 0.001) alongside elevated functional impairments (r values from 0.89 to 0.94, p < 0.001) for both genders. Additionally, linear regression analyses illuminated the consequential impact of specific psychological variables such as the BDI, FABQ-PA, and PCS on muscle endurance and functional impairments (all p < 0.001). This study reveals gender-specific variations in chronic back pain, highlighting the influence of psychological factors on pain perception. It underscores the necessity for gender-sensitive treatment strategies. Future research is needed to explore these differences further and assess treatment efficacy to improve care and quality of life for chronic low back pain sufferers through personalized treatment plans.

Lumbar spondylosis, characterized by degenerative changes in the lumbar spine, often leads to pain, reduced spinal stability, and musculoskeletal dysfunction. Understanding the impact of lumbar spondylosis on musculoskeletal function, particularly lumbar extensor endurance, functional balance, and limits of stability, is crucial for improving the management and well-being of affected individuals. This study aimed to assess lumbar extensor endurance, functional balance, and limits of stability in individuals with lumbar spondylosis compared to age-matched healthy individuals and explore the correlations among these parameters within the lumbar spondylosis group. The lumbar spondylosis group consisted of 60 individuals initially screened by an orthopedician and referred to physical therapy. Age-matched healthy controls (n = 60) were recruited. Inclusion criteria encompassed adults aged 45–70 years for both groups. Lumbar extensor endurance was assessed using the Sorensen test, functional balance with the Berg Balance Scale, and limits of stability using a computerized stabilometric force platform. Lumbar extensor endurance was significantly lower in individuals with lumbar spondylosis compared to healthy controls (23.06 s vs. 52.45 s, p < 0.001). Functional balance, as assessed by the Berg Balance Scale, demonstrated a significant decrement in the lumbar spondylosis group (48.36 vs. 53.34, p < 0.001). Additionally, limits of stability variables, under both eyes-open and eyes-closed conditions, exhibited marked impairments in the lumbar spondylosis group (p < 0.001 for all variables). Within the lumbar spondylosis group, lumbar extensor endurance exhibited significant positive correlations with functional balance (0.46, p < 0.001) and negative correlations with limits of stability variables (r ranging from −0.38 to −0.49, p < 0.01 for all variables). This study underscores the significance of addressing lumbar extensor endurance, functional balance, and stability impairments in the comprehensive management of lumbar spondylosis.

Background: Meniscal injuries are common athletic injuries, and isolated meniscal repair is a critical procedure for restoring knee function. However, rehabilitation protocols after meniscal repair remain controversial. This systematic review aimed to evaluate rehabilitation protocols to determine the best strategies for enhancing recovery following isolated meniscal repair. Objectives: Analyze current rehabilitation protocols following isolated meniscal repair, focusing on the efficacy of approaches in improving functional outcomes and reducing recovery time. This study also aims to identify gaps in the existing literature and provide recommendations for future studies. Data sources: Search was conducted using PubMed, Scopus, and Web of Science databases, covering studies published between May 2015 and May 2024. Inclusion criteria: Studies reporting on isolated meniscal repair with defined postoperative rehabilitation protocols and quantifiable outcome measures. Data extraction: Focused on patient demographics, meniscal tear types, repair techniques, and rehabilitation outcomes. The methodological quality of the included studies was assessed, and narrative synthesis was conducted. Results: The review included 13 studies with significant variability in rehabilitation protocols and outcomes. Early weight-bearing and range of motion exercises have been associated with improved recovery in some studies for stable meniscal tears. However, conservative approaches have better outcomes in patients with complex tears. The use of adjunctive therapies such as blood flow restriction training has demonstrated potential in enhancing muscle preservation and overall recovery. Conclusions: Rehabilitation protocols after meniscal repair surgery should be individualized. Although innovative protocols show promise, further research is needed to standardize rehabilitation approaches and optimize long-term outcomes.

Background and Objectives: Chronic low back pain, frequently attributed to Sacroiliac Joint Dysfunction (SIJD), remains a prevalent concern in orthopedic and physiotherapy arenas. Despite the recognition of motor control exercises (MCEs) and balance training (BT) as potential rehabilitative measures, studies elucidating their combined efficiency for SIJD are scarce. This research study aimed to ascertain the combined and individual efficacies of MCE and BT in alleviating SIJD symptoms. Methods: A double-blinded randomized controlled trial was conducted, enrolling 120 SIJD-diagnosed patients aged 30–60 years. Participants were randomly allocated into four groups: MCEs alone, BT alone, combined MCEs and BT, and a control group receiving usual care. Interventions spanned 12 weeks, with evaluations at the start and end and a 24-week follow-up. Primary outcomes encompass pain intensity (assessed via Visual Analog Scale), functional disability (utilizing the Oswestry Disability Index), and life quality (using the Short Form-36). Results: Post a 12-week intervention, participants receiving combined MCE and BT demonstrated substantial improvements in VAS (Median: 3.5, IQR: 2–5; p = 0.0035), ODI (Median: 15%, IQR: 10–20%; p = 0.0035), and SF-36 scores (Median: 70, IQR: 65–75; p = 0.0035) compared to baseline. In contrast, standalone MCE or BT and control groups exhibited lesser efficacy. By the 24-week follow-up, the combined group maintained their gains, outperforming the other groups. The research tools employed showed high reliability with Cronbach’s alpha >0.85. Conclusions: Our findings underscore the superior efficacy of integrating motor control exercises (MCEs) and balance training (BT) for Sacroiliac Joint Dysfunction (SIJD)-related chronic low back pain. This combined approach promises enhanced patient outcomes, highlighting its potential as a primary strategy in SIJD management. Future studies should further explore its long-term benefits and integration with other therapeutic modalities.
