title: Patients' sensation during and after laserneedle versus metal needle treatment.
abstract: OBJECTIVE
  Aim of the study was to evaluate the patients' sensations during and after laserneedle versus metal needle acupuncture.
  
  
  METHODS
  The prospective study was performed at the gynaecological outpatient department of a University Teaching Hospital of Bern, Switzerland. Thirty female patients per group were included in the study and randomized into laserneedle or metal needle group. All women visited the acupuncture out patient department because of gynaecological disorders. Age of the patients in the metal needle group was 38 years in median (range 18-73 years); mean age was 41+/-13.3. Age in the laserneedle group was 36 years in median (range 16-60 years) and mean age was 39.1+/-12.2. Interventions were laserneedle acupuncture and metal needle acupuncture. Patients answered a questionnaire before, after the first treatment and prior to the second treatment. The questionnaires asked about the patients' knowledge of the various acupuncture methods and their health condition before treatment, their perception of pain, warmth, tiredness and relaxation during or after application of the needles or during or after the treatment. Statistics were performed by Graph Pad InStat 3 for windows.
  
  
  RESULTS
  The common metal needle technique was well known by the patients in comparison to the laserneedle method (p<0.0001***). Laserneedle acupuncture is a method which is painless (p<0.0001***), energy inducing and relaxing (p=0.0257*) which leads to a warming sensation (p=0.0009***) during treatment.
  
  
  CONCLUSIONS
  Both methods laserneedle and metal needle acupuncture are valuable methods in achieving relaxation and improvement of gynaecological symptoms. Laserneedle acupuncture is painless and easy to apply which is a valuable reason to support this technique in the future.
