Abstract
BackgroundStudies to determine gender response to transcutaneous electrical nerve stimulation (TENS) application on individuals who presented with post-injection sciatic pain (PISP) following gluteal injection is not common. A total of 40 subjects comprising 20 males and 20 females who were purposively recruited and conveniently assigned to group A (male) and group B (female) completed the study. Acupuncture-like TENS (AL-TENS) was applied on the 20 male and 20 female subjects, 1 h per session, 3 times per week for the 10 weeks the study lasted.ResultThe pre-intervention baseline scores for the two groups were 8.80 + 1.05 (Female) and 8.60 + 1.27 (Male). The result revealed that after 10 weeks of intervention the VAS scores were 2.60+ 3.28 (p < 0.001) and 2.40 + 3.28 (p < 0.001) for the female and male subjects, respectively. The mean comparison of the female mean VAS scores (2.60 + 3.28) and male VAS scores 2.40 + 3.25 after 10 weeks of AL-TENS intervention shows no statistically significant difference (p > 0.85) in pain intensity (pain perception).ConclusionsThere was no gender variation in pain perception in subjects with post-injection sciatic pain (PISP) following gluteal muscle injection after 10 weeks of AL-TENS application. Therefore, gender-based variation should not be considered when applying AL-TENS as an instrument of intervention in subjects with PISP.Trial registrationPACTR2018050034082
Highlights
Post-injection sciatic pain is a peculiar type of pain that stems from an injury to the sciatic nerve, and its clinical presentations mimic that of sciatica only that its pain stems inferiorly and dorsally from the injection site downward [1]
The current study, aims to assess gender variation in pain perception after 10 weeks of AL-transcutaneous electrical nerve stimulation (TENS) application in patients who presented with post-injection sciatic pain (PISP)
Participants The 40 participants met the under listed criteria before participation in the study: age between 15 and 60 years, not obese, sciatic pain that resulted from intramuscular injection with unilateral involvement of lower limb; post-injection sciatic pain that has not existed for more than 1 year; subjects with no muscular wasting; and those who agreed to stop all forms of analgesic medications for 1 week before the study up until the end of the data collation
Summary
The pre-intervention baseline scores for the two groups were 8.80 + 1.05 (Female) and 8.60 + 1.27 (Male). The result revealed that after 10 weeks of intervention the VAS scores were 2.60+ 3.28 (p < 0.001) and 2.40 + 3.28 (p < 0.001) for the female and male subjects, respectively. The mean comparison of the female mean VAS scores (2.60 + 3.28) and male VAS scores 2.40 + 3.25 after 10 weeks of AL-TENS intervention shows no statistically significant difference (p > 0.85) in pain intensity (pain perception)
