Abstract
Purpose: The purpose of this study was to compare the effects of scrambler and transcutaneous electrical nerve stimulation therapy on pain, functional disability, and depression in patients with chronic low back pain.
Methods: Twenty patients with chronic stroke were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed scrambler therapy. The control group performed electrical nerve stimulation therapy. Training was conducted once a day for 30 minutes, five days per week, for three weeks. The pain was measured using the numeric rating scale. Functional disability was measured using the Roland-Morris disability questionnaire. Depression was measured using the Beck depression inventory.
Results: As a result of comparison between the groups, the experimental and control groups showed significant difference for pain, functional disability and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which scrambler therapy was applied, showed a more significant reduction in pain, functional disability and depression than the control group (p<0.05).
Conclusion: Based on these results, scrambler therapy shows positive effects on pain, functional disability, and depression in patients with chronic low back pain.
