INTRODUCTION Low back pain (LBP) is recognized as one of the most prevalent musculoskeletal disorders globally and remains the leading cause of disability worldwide. Recent evidence indicates that LBP affects up to 84% of the population during their lifetime, with projections suggesting that the number of cases may exceed 800 million by 2050 . This condition significantly impacts individualsAo functional capacity, productivity, and quality of life, making it a major public health concern both globally and locally. In Indonesia, the prevalence of LBP ranges between 7. 6% and 37%, with approximately 80% of individuals experiencing at least one episode during their lifetime, reflecting a substantial burden in developing countries. These findings underscore the urgency of identifying effective, evidence-based interventions for LBP management. From a pathophysiological perspective, the majority of LBP cases . pproximately 90%) are classified as non-specific low back pain (NSLBP), primarily associated with mechanical dysfunctions such as muscle strain, myofascial trigger points, and postural abnormalities. Myofascial pain, characterized by localized tenderness and referred pain patterns, is commonly linked to the presence of trigger points and muscle tightness, which can reduce range of motion (ROM) and increase pain Contemporary research highlights that LBP is not solely influenced by muscular factors but also involves complex interactions between soft tissues, fascia, and neuromuscular control systems, suggesting the need for comprehensive therapeutic approaches . Krisnayantyo. Indonesian Journal of Exercise Therapy and Rehabilitation 2026 (Apri. INJETER, 2,. 130-136 eISSN: 3108-9216 https://journals. id/index. php/khater In clinical practice, non-pharmacological interventions are widely recommended as first-line treatment strategies for LBP, particularly manual therapy and exercise-based rehabilitation. Systematic reviews have demonstrated that massage therapy, trigger point therapy, and stretching can contribute to pain reduction, improved flexibility, and enhanced functional outcomes . Deep tissue massage has been shown to effectively reduce muscle tension and improve ROM by targeting deeper layers of soft tissue, while stretching interventions enhance muscle extensibility and biomechanical efficiency . Additionally, trigger point therapy is known to modulate pain through neurophysiological mechanisms such as the gate control theory and endorphin release, thereby decreasing pain perception. Despite the growing body of evidence supporting individual therapeutic modalities, existing studies predominantly focus on single interventions rather than integrated or multimodal approaches. For instance, . examined the comparative effectiveness of deep tissue massage combined with stretching but did not include trigger point therapy as part of the intervention. Similarly, . emphasized the role of manual therapy but highlighted inconsistencies in outcome measures and intervention These limitations indicate a significant research gap regarding the combined effectiveness of multiple manual therapy techniques applied simultaneously in LBP management. Furthermore, recent literature suggests that multimodal interventions may provide superior outcomes compared to single-modality treatments due to their ability to address multiple underlying mechanisms of LBP, including muscular tension, neural sensitization, and biomechanical dysfunction. However, the evidence remains inconclusive due to heterogeneity in study designs, sample characteristics, and treatment protocols . This gap highlights the need for well-structured experimental studies that evaluate the synergistic effects of combining trigger point therapy, deep tissue massage, and stretching within a single treatment framework. Based on these considerations, the present study aims to examine the effectiveness of a multimodal intervention consisting of trigger point therapy, deep tissue massage, and stretching in patients with low back pain. Specifically, this study seeks to evaluate the extent to which this combined intervention reduces pain intensity and improves flexibility as key indicators of functional recovery. employing a pre-experimental design, this research attempts to provide empirical evidence on the clinical benefits of integrating multiple therapeutic techniques. This study is expected to contribute both theoretically and practically to the field of rehabilitation and sports therapy. Theoretically, it enriches the existing body of knowledge by providing empirical support for multimodal intervention frameworks in LBP management. Practically, the findings may serve as a reference for clinicians, physiotherapists, and sports therapists in developing more effective, evidence-based treatment protocols. Moreover, this research may inform future studies aimed at optimizing intervention strategies and addressing the limitations of current therapeutic approaches. METHOD Research Subjects This study employed a quantitative approach involving participants diagnosed with non-specific low back pain (NSLBP) in the acute and subacute phases. The target population consisted of adult patients experiencing LBP symptoms within community-based clinical settings. A non-probability sampling technique, specifically incidental sampling, was applied to recruit participants who met the inclusion criteria during the study period. A total of 21 participants were included, which is consistent with recommendations for preliminary experimental studies exploring treatment effectiveness in clinical contexts . Inclusion criteria comprised individuals aged 20Ae70 years diagnosed with NSLBP, while exclusion criteria included patients with specific spinal pathologies such as fractures, tumors, or neurological disorders. The selection of this sampling method was justified by the accessibility of participants and the exploratory nature of the study, which aimed to evaluate the initial effectiveness of a multimodal intervention in real clinical conditions . Ethical considerations were maintained by ensuring informed consent and confidentiality of participant data throughout the study.

The magnitude of pain reduction . 52%) observed in this study suggests a strong therapeutic effect compared to baseline conditions, reinforcing the clinical relevance of multimodal approaches. From a theoretical perspective, the observed outcomes can be explained through several physiological and neurobiological mechanisms. Trigger point therapy is known to reduce myofascial pain by releasing localized muscle tension and modulating nociceptive input through mechanisms such as the gate control theory and endogenous opioid release . Deep tissue massage contributes by improving blood circulation, reducing muscle stiffness, and facilitating tissue recovery at deeper muscular layers . Meanwhile, stretching enhances muscle extensibility and viscoelastic properties, leading to improved range of motion and reduced mechanical stress on the lumbar region . The integration of these modalities likely creates a synergistic effect, targeting multiple underlying causes of NSLBP simultaneously, including muscle tightness, reduced flexibility, and neuromuscular The findings of this study are consistent with recent empirical evidence supporting the effectiveness of manual therapy and exercise-based interventions for LBP management. reported that massage therapy significantly reduces musculoskeletal pain, while . demonstrated that deep tissue massage improves both pain and range of motion. Similarly, . found that stretching interventions significantly enhance flexibility and reduce instability in patients with LBP. However, unlike these studies, which primarily examined single modalities, the present study highlights the added value of combining multiple interventions within a single treatment session.

Despite the overall positive findings, the results also reveal variations in the degree of improvement across different flexibility measures. While ante flexion showed substantial improvement . 12%), lateral flexion . extro and sinistr. exhibited relatively smaller gains . 37% and 7. This discrepancy may be attributed to several factors, including differences in muscle group involvement, baseline functional limitations, and the specificity of the intervention techniques Ante flexion movements are more directly influenced by posterior chain flexibility . hamstrings and erector spina. , which were extensively targeted during the intervention. In contrast, lateral flexion involves more complex neuromuscular coordination and may require more targeted or prolonged interventions to achieve significant improvements . Several factors may have contributed to the effectiveness of the intervention. First, the sequential application of trigger point therapy, deep tissue massage, and stretching likely enhanced tissue readiness, allowing subsequent techniques to be more effective. Second, the involvement of multiple muscle groups across the lumbar, pelvic, and lower extremity regions ensured a comprehensive treatment approach. Third, the duration of the intervention . pproximately 50 minute. may have been sufficient to induce acute physiological changes, such as increased circulation and reduced muscle tone. However, it is important to note that individual variability, including age, activity level, and severity of symptoms, may also influence treatment outcomes. Nevertheless, this study has several limitations that should be considered when interpreting the The use of a pre-experimental one-group pretestAeposttest design without a control group limits the ability to establish causal relationships and increases the risk of internal validity threats, such as placebo effects and natural recovery. Additionally, the relatively small sample size . = . restricts the generalizability of the results to broader populations. The short duration of the intervention also limits the ability to assess long-term effects and sustainability of the outcomes. Future research should consider employing randomized controlled trial (RCT) designs with larger sample sizes and longer follow-up periods to validate and extend these findings. In terms of practical implications, the results of this study suggest that multimodal manual therapy can be an effective non-pharmacological intervention for managing NSLBP. Clinicians, physiotherapists, and sports therapists may consider integrating trigger point therapy, deep tissue massage, and stretching into a single treatment protocol to optimize patient outcomes. From a theoretical standpoint, this study contributes to the growing body of literature emphasizing the importance of multimodal and integrative approaches in musculoskeletal rehabilitation. It highlights the need for treatment strategies that address the complex and multifactorial nature of LBP rather than relying on single-modality interventions. In conclusion, the findings of this study provide evidence that a multimodal intervention combining trigger point therapy, deep tissue massage, and stretching is effective in reducing pain and improving flexibility in patients with NSLBP. The results underscore the importance of integrated therapeutic approaches in addressing musculoskeletal disorders and offer a foundation for future research aimed at optimizing rehabilitation protocols and improving patient outcomes. CONCLUSION This study concludes that a multimodal intervention combining trigger point therapy, deep tissue massage, and stretching is effective in reducing pain intensity and improving lumbar flexibility in patients with non-specific low back pain, as evidenced by significant differences between pretest and posttest outcomes. These findings directly address the research objective and demonstrate that integrating multiple manual therapy techniques can produce meaningful clinical improvements within a short intervention period. Theoretically, this study contributes to the development of rehabilitation science by reinforcing the concept that low back pain management benefits from a multimodal and integrative approach targeting both neuromuscular and biomechanical factors. Practically, the results provide a relevant basis for clinicians, physiotherapists, and sports therapists to implement combined therapy protocols as a non-pharmacological strategy for managing low back pain. However, this study is limited by the use of a pre-experimental design without a control group, a relatively small sample size, and the absence of long-term follow-up, which may affect the generalizability and sustainability of the Therefore, future research is recommended to employ randomized controlled trial designs Krisnayantyo.
