简要总结
The unilateral transverse rectus abdominis musculocutaneous (TRAM) flap is a major operation widely used for breast reconstruction. It is hypothesized that this surgery has the potential risk of weakening the abdominal wall because it disrupts the integrity of the rectus abdominis muscle (RA), therefore, alters the insertion of the oblique muscles and the biomechanical relationship between the RA muscle and adjacent structures. The purposes of this study were to examine the effects of the TRAM flap surgery on muscle size of abdominal muscles, strength and endurance of trunk muscles, strength and endurance of core stability, as well as the effects of therapeutic exercises on it in post-mastectomy women underwent TRAM surgery.
详细描述
This first year of the proposed study was aimed to understand the impacts on abdominal muscle functions. We design a case-control, cross-sectional study. There were 46 women who have undergone TRAM flap and 36 age-matched healthy women. We recorded the biomechanic and electromyographic responses during voluntary limb movements and elicited by unexpected support surface translations and tilts in standing. A six-camera Qualisys motion system was used. Ground reaction forces and moments were acquired by one Kisler force plate. Surface electromyography electrodes were used to record the activity of selected trunk and limb muscles. The second year was aimed to evaluate the effects on abdominal muscle functions after 12 weeks abdominal muscle training in the TRAM women. Outcome measures were the clinical tests for trunk muscle strength, endurance and one-leg standing was also used to exam the abdominal muscle function.
