Can pulsed electro-magnetic field (PEMF) therapy enhance calf muscle function in healthy individuals
Refereed conference paper presented and published in conference proceedings


摘要Introduction: Since recent studies have proven that pulsed electro-magnetic field (PEMF) has positive effects on myogenesis and mitochondriogenesis, this study aimed to investigate the effectiveness of PEMF therapy on calf muscles of healthy individuals with different activity levels.
Methods: All subjects underwent the same PEMF intervention on the right calf, consisting of 8 sessions over 4 weeks. Each PEMF session was 20 minutes with the PEMF exposure set at 1.5 mT and 10 Hz, summing up to 160 minutes of PEMF exposure. Basic demographics and the Tegner activity scores based on physical activity level were obtained from each participant. Functional outcomes of the calf muscles including calf circumference, number of heel rises and calf strength were measured at baseline and also at the end of the treatment course. The change in the functional outcomes will be compared between subjects with different Tegner activity levels.
Results: Eleven healthy individuals aged 18-35 were recruited with a body mass index 18.5-22.9. For participants with low physical activity level (0-5), there were statistically significant increases in terms of calf circumference (p=0.011), calf raise (p=0.018) and calf strength (p=0.05). For participants with high physical activity level (6-10), no statistical significant differences were found in all outcomes.
Discussion and Conclusion: A 160-minute course of non-invasive PEMF effectively enhances calf muscle mass, endurance, and strength especially in the less physically active population. Therefore, PEMF could possibly become a useful treatment modality for sarcopenic or sedentary individuals or patients undergoing rehabilitation. Further investigations are required to determine the optimal dosage and clinical application of PEMF.
