Effect of pain scrambler therapy on shoulder joint pain and range of motion in patients who had undergone arthroscopic rotator cuff repair for the first time

[Purpose] This study aimed to determine the effect of pain scrambler therapy on shoulder joint pain and range of motion in patients who had undergone arthroscopic rotator cuff repair for the first time. [Subjects and Methods] Pain scrambler therapy was administered once a day every 40 minutes for 10 days to patients that had undergone arthroscopic rotator cuff repair for the first time. The visual analog scale was used to measure pain, and a goniometer was used to measure shoulder range of motion. [Results] After 10 sessions of pain scrambler therapy, pain was significantly reduced from that before the treatment. In addition, shoulder range of motion was increased after 10 treatment sessions. [Conclusion] Thus, pain scrambler therapy greatly reduced pain and increased should range of motion in the patients who had undergone arthroscopic rotator cuff repair for the first time.
