结局指标
主要结局
Numeric Rating Scale (NRS)
时间窗: Immediately after treatment
The Numeric Rating Scale (NRS) is a numbered version of the Visual Analog Pain Scale (VAS) in which the patient can select one number that best describes the pain. Scale from minimum "0" to maximum "10" for total 11 integers. "0" represents no pain, and "10" represents worst pain imaginable.
次要结局
- Skin temperature(Baseline, immediately after treatment)
- Number of treatment interruptions(Immediately after treatment)
