Soft tissue mobilization techniques in treating chronic abdominal scar tissue: A quasi-experimental single subject design.

INTRODUCTION

Roughly 17 million abdominal surgeries are performed annually in the U.S. Up to 17% of those may be readmitted for adhesion related problems. This study evaluated the effectiveness of soft tissue mobilization (STM) techniques at improving chronic pain, mobility restrictions and functional deficits following complex abdominal surgery.

METHODS

Subjects Two females aged 51 and 65.

DESIGN

Single subject quasi-experimental A-B-A.

INTERVENTION

Four 30-min treatment sessions of abdominal tissue mobilizations. Outcome measures Pain pressure threshold (PPT) and average scar mobility (ASM), Numeric Pain Rating Scale (NPRS), and the Oswestry Disability Index (ODI).

RESULTS

Subject 1 ASM and PPT of the abdomen improved significantly and exceeded the established standard error of measurement (SEM). PPT of the scar decreased during the second baseline. This decrease exceeded the SEM for PPT but was not statistically significant. The changes in NPRS did not reach the minimal clinically important difference (MCID). Subject 2 abdominal PPT and ASM showed statistically significant improvements that exceeded their SEMs. Scar PPT showed improvement during the repeat baseline, however, this reached neither statistical significance nor the SEM.

CONCLUSIONS

Scar mobility and abdominal PPT improved both statistically and clinically in both subjects after only 4 sessions of STM. Scar pain measured by NPRS and PPT did not show significant improvement. This study demonstrated that STM can be an effective way to treat chronic abdominal scars by increasing scar mobility and reducing abdominal sensitivity to pressure. It is non-invasive, and is a less costly alternative to laparoscopic adhesiolysis.
