- The study investigates the effectiveness of transcutaneous electrical nerve stimulation (TENS) specifically on post-injection sciatic pain (PISP), an issue often arising from incorrect intramuscular injections, which has not been extensively researched before.
- Conducted with 72 participants split into a TENS treatment group (40 subjects) and a control group receiving sham treatment (32 subjects), the study involved three weekly sessions over ten weeks, utilizing the Visual Analogue Scale for pain measurement.
- Results indicated that the TENS group experienced a significant reduction in pain levels compared to the control group, with the intervention explaining 19% of the observed variance in pain relief (p = 0.01), highlighting TENS as a potentially effective
