Highlights
- Myofascial vacuum therapy with negative pulsed pressure, combined with core exercise, significantly reduced chronic non-specific low back pain.
- Improvements observed in pain intensity, pressure pain threshold, mobility, functionality, and quality of life.
- Benefits were superior to a program based on therapeutic exercise alone.
- Effects were maintained at 1- and 3-month follow-ups.
- Single-blind randomized controlled trial supports the clinical relevance of vacuum-based interventions.
Study Design
This study was a single-blind randomized controlled trial including 50 participants with chronic non-specific low back pain.
Participants were randomly allocated into two groups:
- VT Group (n = 25):
Myofascial vacuum therapy with negative pulsed pressure combined with core therapeutic exercises. - PTP Group (n = 25):
Physical therapy program based exclusively on core therapeutic exercises.
Intervention details:
- 15 sessions over 5 weeks
- 30 minutes per session
- Negative pressure: 80–100 mb, applied intermittently
- Treated muscles: quadratus lumborum, piriformis, psoas, and paravertebral muscles
Assessments were conducted at baseline, post-treatment, and at 1- and 3-month follow-ups.
What Did They Find?
Compared to the exercise-only group, the vacuum therapy group showed statistically significant improvements in:
- Pain intensity
- Pressure pain threshold
- Lumbar range of motion
- Functional capacity
- Quality of life
These improvements were evident immediately after treatment and remained present at follow-up evaluations.
Figure 1. Negative Pulsed-Pressure Myofascial Vacuum Therapy + Exercise (blue) vs Exercise Alone (orange). At 3-month follow-up, participants receiving negative pulsed-pressure myofascial vacuum therapy combined with core exercises (blue) demonstrated greater improvements in pain, lumbar mobility, pressure pain threshold, functional capacity, and physical quality of life compared to exercise alone (orange).
Why It Matters
Chronic non-specific low back pain is one of the most prevalent musculoskeletal conditions worldwide and remains challenging to manage.
This study demonstrates that negative pulsed-pressure myofascial vacuum therapy, when combined with therapeutic exercise:
- Enhances clinical outcomes beyond exercise alone
- Offers a non-invasive and well-tolerated adjunct therapy
- May improve both mechanical and sensory aspects of pain
- Supports a multimodal approach to chronic low back pain management
These findings strengthen the scientific basis for incorporating vacuum-based myofascial therapies into evidence-informed rehabilitation programs.
