Summary
Peripheral nerve stimulation improved left hip pain and psoas muscle atrophy in a patient with lumbar spinal nerve issues. This novel approach showed significant pain reduction and muscle recovery, documented by electromyography.
Area of Science:
- Neurology
- Musculoskeletal Medicine
- Pain Management
Background:
- The psoas muscle, crucial for lumbar spine function, is innervated by lumbar spinal nerve roots (L2-L4).
- Psoas muscle dysfunction can manifest as hip and hamstring pain, often associated with muscle atrophy.
Observation:
- A 44-year-old female presented with posterolateral left hip pain radiating to the ipsilateral hamstring.
- Imaging revealed psoas muscle atrophy, suggesting underlying neuromuscular compromise.
Findings:
- Temporary peripheral nerve stimulation targeting the psoas muscle resulted in over 50% improvement in pain scores.
- Electromyography (EMG) documented significant improvement in psoas muscle atrophy post-stimulation.
Implications:
- This case study is the first to demonstrate EMG-verified improvement in muscle atrophy following peripheral nerve stimulation.
- Peripheral nerve stimulation presents a potential therapeutic strategy for psoas muscle atrophy and associated pain.
- Further research is warranted to explore the efficacy and long-term outcomes of this intervention.
