Background: Diminished counts of circulating red blood cells (RBC) and hemoglobin 
(Hb) concentrations are common in iron deficiency anemia (IDA). Both transcutaneous 
electrical nerve stimulation (TENS-A) at acupoints and aerobic exercise are effective in 
managing IDA. Purpose: comparing the effect of aerobic exercise (performed as 
treadmill walking exercise) and TENS-A in IDA women. Methods:Women (n = 60) 
with IDA were randomly allocated to the TENS-A group (n = 30) and the group of 
aerobic exercise (GAE, n = 30). In the TENS-A group, electrodes were applied over 
bilateral GB39 and SP6 acupoints. In the GAE, women with IDA received mildly 
intense aerobic exercise (treadmill walking exercise). To be noted, for 12 weeks, the 
session of exercise, or TENS-A, was 30 minutes and applied three times weekly. 
Outcomes: IDA women's concentration of Hb, count of RBC, and mean corpuscular 
volume (MCV) were recorded in both groups. Results: Between-group analysis of 
women with IDA revealed that the TENS-A group's Hb concentration and RBC count 
were significantly higher than the other group, GAE (p > 0.01). Following both 
treatments, TENS-A or aerobic exercise, there was no discernible change in MCV 
between the TENS-A and GAE groups (p > 0.05).Conclusion:  TENS-A 
and aerobic exercise have a substantial positive impact on women's IDA; however, the 
effects of TENS-A were greater in Hb concentration and RBC count than those of 
aerobic exercise. suggesting its potential as a valuable treatment option alongside 
conventional therapies.
