Effects of scrambler therapy on pain and depression of patients with chronic low back pain: case study.
Ji-Won Han, Dong-Kyu Lee
PMID 30034096WHAT IT FOUND
In a single man with chronic low back pain, pain and depression scores were lower after 10 days of scrambler therapy.
This describes one person's response, not proof that the treatment works.
Key findings
01Pain score on a 0 to 10 scale fell from 8 to 1 after 10 days of scrambler therapy.
02Depression score on a 0 to 63 scale fell from 22 to 7 after scrambler therapy.
03The report describes one patient and had no follow-up, so it cannot show whether the changes lasted.

What it does not show
This was a single case study, so it cannot show that scrambler therapy works for chronic low back pain. There was no follow-up after the 10 days, so it is unknown whether the lower scores lasted. The paper lists weight as 169 cm and height as 65 kg, so the participant measurements are reported inconsistently.
Declared interests
The authors declared no conflict of interest.
The easy way to misread this
Do not read the change from 8 to 1 as proof that scrambler therapy works for chronic low back pain. This was a single case with no follow-up.
