Noninvasive and completely safe. The flexor retinaculum is tightened in carpal tunnel syn Chat Doctor.  With therapeutic ultrasound therapy and TENS therapy, the inflammation and pain will be reduced. MFR and IA STM will help reduce the spasm too. Some exercises to improve muscle strength and avoid spasm as well. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In </s>
