Efficacy of Neuromodulation Therapy for Neuropathy Symptom Reduction and Functional Improvement

Targeted neuromodulation therapies are increasingly used for the management of peripheral neuropathy; however, data on symptom and functional outcomes following standardized treatment courses remain limited. This report evaluates the efficacy of NeuroGen Neuromodulation treatments administered at the National Neuropathy Center, focusing on changes in sensory symptoms and functional task performance from the first treatment (T1) to the twelfth treatment (T12) over a mean treatment duration of 36 sessions.

Patients completing a standardized 12-treatment course using the NeuroGen Neuromodulation device were analyzed. Outcomes included patient-reported sensory symptoms (tingling, numbness, and pain) and measures of functional task performance. Changes from baseline (T1) to posttreatment (T12) were assessed to determine treatment effectiveness, response patterns, and areas for clinical optimization.

Patients demonstrated clear and measurable benefits following completion of 12 treatments. The greatest improvements were observed in sensory symptoms, with tingling, numbness, and pain each improving by approximately one point on the severity scale. More than half of patients achieved clinically meaningful relief in these sensory domains. Functional improvement was more modest, with meaningful gains observed in approximately one-quarter to one-third of patients. Nonresponse rates were low, although residual symptoms and functional limitations remained common.

The standard NeuroGen Neuromodulation treatment protocol provides substantial relief of sensory neuropathic symptoms, with consistent benefits across patients. While functional gains were less pronounced, the low nonresponse rate supports overall treatment effectiveness. Persistent symptoms in some patients suggest a potential role for maintenance therapy and adjunctive interventions to optimize long-term outcomes.
