Objective:
To compare extracorporeal shock wave therapy combined with oral medication and an exercise program vs sham treatment with medication and exercise for the treatment of chronic low back pain (CLBP).
Design:
Randomized controlled trial.
Setting:
Outpatient clinic at a university hospital.
Participants:
Eligibility criteria were age older than 18 years and duration of CLBP exceeding 3 months. Exclusion criteria were concurrent treatment or history of surgery for CLBP, cancer, fractures, infections, and disk degeneration.
Intervention:
The intervention group received extracorporeal shock wave therapy once a week for 4 weeks along with oral medications and an exercise program. The control group received sham extracorporeal shock wave therapy along with oral medications and an exercise program.
Main Outcome Measures:
Visual analog scale and Oswestry Disability Index (ODI) were used to assess pain and disability at baseline and after 3 months.
Results:
The pain score in the intervention group (N=16) was 6.6 at baseline and 3.0 after 1 month (P<.0001) and 1.8 after 3 months (P<.0001). In the control group (N=16), the pain score was 6.8 at baseline, 4.6 after 1 month (P<.0001), and 1.1 after 3 months (P<.0001). ODI scores decreased significantly in both groups compared with baseline values (first month: P<.001, third month: P<.05). The mean ODI score did not differ significantly between the groups (P=.942).
Conclusion:
Extracorporeal shock wave therapy combined with oral medication and exercise was safe and effective in the short-term treatment of chronic low back pain.
