Özet
Objective: Chronic low back pain (CLBP) represents one of the most challenging and costly musculoskeletal conditions to manage. A variety of therapeutic approaches, including exercise training, pain management strategies, and spinal manipulation and mobilization, are employed in its treatment. Among these, clinical spinal manipulation and mobilization techniques are widely regarded as one of the most effective interventions for reducing pain and disability, offering both short-and long-term benefits. High-velocity spinal manipulation is commonly adopted for treating CLBP and has been associated with changes in muscle activity, but the evidence is controversial. The aim of this study was to analyze the immediate effects of two manual spinal techniques (MST) on pain, flexibility, and muscle mechanical properties in CLBP. Materials and Methods: This single-blinded, randomized comparative trial used a pre-and post-test design. Participants were randomly assigned to two groups: Group 1 received Maitland's posterior-anterior central vertebral pressure mobilization technique, and group 2 underwent the lumbar roll technique. Assessments were conducted at baseline and immediately after the interventions. Muscle mechanical properties were measured using MyotonPro, pain intensity was evaluated using a visual analog scale (VAS), and flexibility was assessed through the sit and reach test and the modified Schober test. Results: Following the interventions, significant improvements were observed in VAS scores and sit-and-reach test results in both groups. Analysis of Schober test data revealed a significant improvement in group 2 (p<0.001). Mechanical properties of the paravertebral muscles at the L3-L4 vertebral level were assessed using MyotonPro, showing statistically significant enhancements in elasticity (Hz) and dynamic stiffness (N/m) in both groups post-intervention. However, no statistically significant differences were identified between the groups. Conclusion: Both MSTs demonstrated efficacy in alleviating pain, reducing muscle stiffness, and enhancing flexibility. In this study, manipulations were applied to the symptomatic side, which yielded positive outcomes in pain reduction and muscle properties. However, further research is needed to determine whether the symptomatic side is superior in terms of therapeutic efficacy.
