PPT and cross-sectional area of active MTrPs were measured using stabilometry, pressure algometery and real-time ultrasound scanning, respectively.
INTERVENTIONS:
The first group performed CS exercises alone, whereas the same exercise program was applied in the second group plus cross-fiber frictions on active MTrPs (3.5 min/MTrP).
RESULTS:
Within-group statistically and clinically significant differences were observed only for group II in PPT. However, group I also exhibited a large effect size with clinically significant changes from baseline on this outcome. Furthermore, patients in group II clinically improved their balance ratios and differed from group I at post-test in the sagittal plane dynamic balance performance of the painful side.
CONCLUSION:
CS exercises immediately increase the PPT of active MTrPs in physically active adults with clinical instability of the lumbar spine and chronic myofascial pain syndrome. When MTrP therapy is added, side-to-side asymmetries in dynamic balance are minimized
