NCT07463729

Brief Summary

The aim of the study is to evaluate the effects of biofeedback-assisted stabilization training and conventional therapy on pain perception, balance, spinal mobility, functional performance, physical activity, stress level, and quality of life in patients with lumbosacral spine pain syndrome treated conservatively. The main research questions the study seeks to answer are as follows: Whether and to what extent the implemented therapeutic program improves balance, spinal mobility, functional performance, physical activity, quality of life, and reduces pain perception and stress levels in patients with lumbosacral spine pain syndrome? Are there differences in therapeutic outcomes depending on the treatment method applied? Are the therapeutic effects maintained three months after completion of the intervention? Researchers will compare two groups: a control group and an experimental group. In the control group, stabilization training will be performed without the use of biofeedback. Participants will undergo clinical and functional assessments (Visual Analogue Scale, Oswestry Disability Index, force platform measurements, etc.). Depending on the group to which participants are randomly assigned, participants will participate in manual therapy, stabilization training, and selected physical therapy modalities. Participants will be continuously supervised by a physician and physiotherapists throughout the 8-week intervention period. Three months after completion of the intervention, participants will undergo a follow-up assessment.

  • Pain Questionnaire

    McGill Pain Questionnaire - Short Form; Evaluation: The McGill Pain Questionnaire - Short Form is a concise tool (15 descriptors) for rapid, multidimensional assessment of pain, including sensory and affective components, as well as pain intensity. Unit of Measure: Patients rate each descriptor on a scale from 0 to 3 (0 = none, 3 = severe). Higher total scores indicate more intense and distressing pain. Measurement Tool: The Short-Form McGill Pain Questionnaire (SF-MPQ) will be used to allow patients to self-report both the intensity and qualitative characteristics of participants pain.

Unit of Measure: The ODI score is expressed as a percentage, calculated from 10 sections (0-5 points each). The total score ranges from 0% to 100%, where higher scores indicate greater disability. Interpretation of scores is as follows: 0-20%: Minimal disability 21-40%: Moderate disability 41-60%: Severe disability 61-80%: Crippling disability 81-100%: Bed-bound or exaggerating symptoms Measurement Tool: The Oswestry Disability Index (ODI) questionnaire will be used to allow patients to self-report limitations in daily activities related to spinal pain.

Study Arms (2)

Biofeedback Group

EXPERIMENTAL

The investigators use in this group standard physiotherapy and ultrasonography as Biofeedback-Assisted Stabilization Training to activate deep muscle of spine.

Other: Standard RehabilitationOther: Biofeedback Ultrasonography

Control Group

OTHER

In this group the investigators use standard physiotherapy without ultrasonography as biofeedback.

Other: Standard Rehabilitation

Interventions

Standard Rehabilitation; Participants in the experimental group will undergo an 8-week rehabilitation program (2 sessions per week) that includes: Manual therapy, Physical therapy modalities, including TENS (Transcutaneous Electrical Nerve Stimulation) and therapeutic ultrasound, applied according to current conservative treatment standards, Standard exercises including muscle stretching, neural mobilization, diaphragmatic breathing, and exercises targeting deep trunk muscles.

Biofeedback GroupControl Group

Biofeedback Ultrasonography: exercises targeting the deep muscles of the spine, performed using ultrasonography for motor learning. The biofeedback allows real-time visualization of deep muscle activation (e.g., transverse abdominal, Pelvic floor muscles), helping participants optimize contraction patterns and improve neuromuscular control of the lumbosacral spine.

PARALLEL
Model Details: Participants will be randomly assigned to one of two parallel groups: an experimental group or a control group. In the control group, an 8-week program (twice weekly) will be implemented, including manual therapy, physical therapy modalities, and therapeutic exercises. In the experimental group, participants will receive the same interventions as described above, with the addition of exercises using biofeedback to facilitate activation of the deep stabilizing muscles of the lumbosacral spine. In both groups, participants will undergo assessments before the intervention, after 8 weeks (post-intervention), and 3 months following completion of the intervention (follow-up).
