Objective: To assess the effectiveness of transcutaneous magnetic stimulation (TMS) in the management of carpal tunnel syndrome (CTS) compared with transcutaneous electrical nerve stimulation (TENS) therapy.
Method: This was a prospective, open-label, randomized study. Eleven patients (15 wrists) diagnosed with CTS, confirmed by nerve conduction study were enrolled. TMS or TENS were applied to the symptomatic wrist 20 minutes per day, 3 times a week for a total of 4 weeks based on the random allocation. Visual analog scale (VAS) and the Boston carpal tunnel syndrome questionnaire (BCTQ) were evaluated before and 4 weeks after TMS or TENS.
Results: VAS changed from 6.9 to 4.6 after TMS, which change was statistically significant (p=0.013), but not after TENS (from 5.9 to 4.1, p=0.150). There was significant difference of VAS change between TMS and TENS (p=0.041). BCTQ changed from 5.9 to 4.0 after TMS and from 6.3 to 4.5 after TENS. The changes of BCTQ after TMS and TENS were statistically significant (p=0.040 and p=0.038) but these changes were not significantly different between TMS and TENS groups (p=0.970).
Conclusion: We found that TMS can be used in the treatment of CTS without direct contact of skin. This has superiority over TENS in terms of easy application to irregular surfaces and areas with skin problems.
