So we modulate TENS and RF into a new stimulation waveform. This PRF peripheral nerve stimulation is mainly divided into five parts; 1) Power source. 2) The circuit of RF modulated by TENS. 3) Voltage and current measurement. 4) MCU control and calculates data. 5) Data storage system. 　　This clinical trial is a comparison that Visual Analogue Scale(VAS) and Constant-Murley Shoulder(CMS) of both Control group and TPRF 300V groups,TPRF 500V groups. This clinical trial a total of 80 patients with shoulder pain. These patients were randomly distributed into three groups.
