Summary
Repetitive Peripheral Magnetic Stimulation (rPMS) effectively reduces postoperative pain and opioid use following foot and ankle surgery. This treatment offers significant improvements in patient pain perception and recovery.
Area of Science:
- Orthopedic Surgery
- Pain Management
- Neuromodulation
Background:
- Postoperative pain is a significant challenge after foot and ankle surgeries.
- Effective pain management strategies are crucial for patient recovery and satisfaction.
Purpose of the Study:
- To evaluate the efficacy of Repetitive Peripheral Magnetic Stimulation (rPMS) in controlling postoperative pain.
- To assess the impact of rPMS on opioid consumption after foot and ankle procedures.
Main Methods:
- A randomized clinical trial involving 67 patients undergoing foot and ankle surgery.
- Patients were assigned to either a control group (placebo) or an experimental group (rPMS) for 5 days postoperatively.
- Pain scores (VAS, BPI, DN4) and functional outcomes (AOFAS) were assessed at multiple time points.
Main Results:
- The rPMS group showed statistically significant improvements in pain perception compared to the control group.
- Repetitive Peripheral Magnetic Stimulation led to a reduction in postoperative opioid consumption.
- Forefoot surgeries were most common, with nociceptive pain being predominant.
Conclusions:
- Repetitive Peripheral Magnetic Stimulation is an effective modality for managing postoperative pain after foot and ankle surgery.
- rPMS contributes to reduced opioid requirements in the postoperative period.
- This study provides Level I evidence supporting rPMS for enhanced pain control.
