Question
A male client has experienced low back pain for several years. He is the primary support of his wife and six children. Although he would qualify for disability, he plans to continue his employment as long as possible. His back pain has increased recently, and he is unable to control it with non-steroidal anti-inflammatory agents.

Which of the following is an appropriate rationale for using a TENS unit for relief of pain?
Options
- ATENS units have an ultrasonic effect that relaxes muscles, decreases joint stiffness, and increases
- BTENS units produce endogenous opioids that affect the central nervous system with analgesic
- CTENS units work on the gate-control theory of pain; biostimulation therapy of large fibers block
- DTENS units prevent muscle spasms, decrease the potential for further injury, and minimize
