The aim of this prospective study is to explore the pain-alleviating effect of low-energy extracorporeal shock wave therapy(ESWT) in patients with chronic low back pain.
- Study Type: Interventional
- Study Design
- Allocation: Non-Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: None (Open Label)
- Study Primary Completion Date: August 2013
26 patients who suffered from persistent symptoms for more than 3 months are going to be treated with DOLORCLAST radial extracorporeal shock wave(EMS, Swiss). Patients are assigned to two groups according to the exist of specific pain spot. Group I(have specific pain spot) received a total of 2000 impulses of 2.5 Bar; group II(controls, no specific pain spot) 4000 impulses of 2.5 Bar. Patients is going to be treated once. The efficacy of therapy is going to be evaluated by VAS scale before and after the treatment.
- Device: Radial Extracorporeal Shock Wave Therapy 2000 impulses
- Radial Extracorporeal Shock Wave Therapy, 13 Hz, 2.5 Bar, 2000 impulses
- Device: Radial Extracorporeal Shock Wave Therapy 4000 impulses
- Radial Extracorporeal Shock Wave Therapy, 13 Hz, 2.5 Bar, 4000 impulses
Arms, Groups and Cohorts
- Experimental: Specific pain spot
- Radial Extracorporeal Shock Wave Therapy 2000 impulses, Patients with specific pain spot for low back pain
- Experimental: No specific pain spot
- Radial Extracorporeal Shock Wave Therapy 4000 impulses, Patients without specific pain spot for low back pain
Clinical Trial Outcome Measures
- Change in Visual analogue scale scores(VAS) of patients before and after therapy
- Time Frame: baseline, 1 hour after therapy
- Change of Visual analogue scale score(VAS) of patients before and after shock wave therapy
