A TENS unit is safe to use in all three trimesters of pregnancy for low back pain? True or False
True
Electrical stimuli are thought to stimulate afferent nerve pathways in the spinal cord. This blocks the transmission of painful stimuli and activates descending inhibitory systems to reduce hyperalgesia. In pregnancy, it is recommended to avoid electrode placement over the gravid abdomen as a precaution to inciting uterine contractions. Placement of electrodes on the painful lumbar area of the back may be safely used during all 3 trimesters of pregnancy.
