Peripheral Nerve Stimulation and Improved Functional Outcomes in a Prosthetic User: A Case Report

Area of Science:

• Neurology
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Chronic postamputation pain significantly impacts patient mobility, function, and prosthesis utilization.
• Current treatment options for postamputation pain are often limited, with underexplored impacts on prosthetic integration.
• Peripheral nerve stimulation (PNS) is an emerging therapeutic modality for neuropathic pain conditions.

Purpose of the Study:

• To evaluate the efficacy of sciatic peripheral nerve stimulation (PNS) in managing chronic postamputation pain.
• To assess the impact of PNS on prosthesis comfort and functional outcomes in an amputee patient.
• To explore the potential advantages of PNS compared to other surgical interventions for prosthetic enhancement.

Main Methods:

• A case report detailing the treatment of a patient with chronic postamputation pain who failed conservative therapies.
• Implementation of sciatic PNS as an interventional pain management strategy.
• Assessment of pain reduction, prosthesis comfort, and functional status using validated measures (e.g., Orthotic and Prosthetic Users Survey Lower Extremity Functional Status Measure, Prosthetic Limb Users Survey of Mobility).

Main Results:

• Successful pain reduction following sciatic PNS treatment.
• Significant improvements in prosthesis comfort and patient-reported functional outcomes.
• Enhanced mobility and overall quality of life post-intervention.

Conclusions:

• Sciatic PNS is a viable and effective treatment for chronic postamputation pain, leading to improved prosthesis use and comfort.
• PNS presents unique advantages over other surgical techniques like targeted muscle reinnervation for prosthetic function.
• This case highlights the potential of PNS to restore function and improve the lives of amputees suffering from chronic pain.
