The purpose of this study is to demonstrate the safety of the AvicennaTM class IV laser for
application over the skin of human subjects. In addition, we seek to measure the
effectiveness and utility of this class 4 laser therapy in the treatment of post-thoracotomy
- Men and women age 25-65 years old with chest wall pain after lung surgery lasting
more than 2 months after surgery.
- Subjects shall have failed conservative treatment which may include rest, physical
therapy, braces, and over the counter anti-inflammatory medications. All those
enrolled will be native English speakers and have at least a high school degree
- Subjects will be excluded if they are pregnant (which will be confirmed by a urine
pregnancy test if they are of childbearing age)
- Have previous history of other pain syndromes or psychiatric disorders.
- We will exclude the morbidly obese (BMI >30) because the laser may not be able to
penetrate deep enough through adipose tissue. In addition, subjects who have had
previous back surgery, or are on antidepressants for the treatment of depression in
the preceding 6 weeks will be excluded as these may represent potential confounding
