Figure 5. Visual analogue scale (VAS) scoring of pain pre- and post-PEMF therapy for 12 weeks. (A) Venn diagram depicting the number of subjects (60 females and 32 males) reporting health conditions as either age-related (blue) or arising from injuries and/or surgeries (yellow) and associated pain (red). The number of subjects for each disorder/injury/surgical intervention are indicated within the parentheses. Pain level before and after PEMF therapy was rated using the VAS “faces” pain rating scale (B), with a rating of 10 indicating strong pain and a rating of 0 indicating no pain. VAS scores were tabulated based on pre-treatment scores between either (C) 0 and 5 (n = 19), or (D) scores above 5 (n = 21). (E) 40 of the 92 subjects completed the VAS pain questionnaire, wherein 83% (33/40) reported chronic pain, amongst whom 21% (7/33) reported age-related disorders and/or 42% (14/33) reported past or recent injuries/surgeries. The mean change in VAS score for subjects in the “0 to 5” bracket (C) was −1.23 points, from a mean of 3.23 to 2.07, before and after PEMF therapy, respectively. The “above 5” group (D) showed a −2.12-point change, from means of 6.57 to 4.45. Statistical analysis was carried out using Wilcoxon matched-pairs signed rank test and showed significant improvement in pain relief with ^***p < 0.001 after magnetic therapy.
