ABSTRACT
The psoas muscle is the largest muscle in the lower lumbar spine and is innervated by the ipsilateral lumbar spinal nerve roots (L2-L4). Here, we present a 44-year-old female with left hip pain in the posterolateral aspect of the left hip radiating to the ipsilateral hamstring, and psoas atrophy (based on imaging). She is now reported to have over 50% improvement in pain scores after underdoing temporary peripheral nerve stimulation of the psoas muscle as well as significant improvement in muscle atrophy based on an electromyography (EMG) study. This case study is the first to report documented improvement in muscle atrophy based on EMG after peripheral nerve stimulation of the targeted area.
In this case study, peripheral nerve stimulation (PNS) was used for a patient suffering from pain and decreased size of the psoas muscle. The psoas muscle is responsible for walking, running and getting up from a seated position and is the largest muscle in the lower back. This study showed that peripheral nerve stimulation was effective not only for the relief of muscle pain but also for recovery of the size of the affected muscle.
