Combined Circulatory and Dietary Interventions for Neuropathy

Официальное название

Combined Circulatory and Dietary Interventions for Neuropathy (CDIN)

Обзор

The purpose of this study is to evaluate the effectiveness of three different interventions in improving neuropathy symptoms in individuals aged 35-85 with moderate to severe neuropathy. The study will compare three treatment groups: Intraneural Facilitation® (INF®) therapy alone, INF® therapy combined with Neuro vascular index (NVI) food-guided elimination (NVIf), and NVIf alone. The aim is to determine which treatment results in the greatest improvement in neuropathy symptoms, including quality of life, sensory and pain improvements, and functional outcomes.

Подробное описание

The purpose of this investigator-initiated study is to observe the effectiveness of a manual physical therapy technique known as Intraneural Facilitation (INF®), both independently and in combination with a Nutritional Vascular Inflammation focused (NVIf) dietary intervention, in improving neurovascular function, pain, and physical performance in individuals with moderate to severe peripheral neuropathy (PN). Subjects will be randomized into one of the three interventions arms: (1) INF® therapy alone, (2) NVIf intervention alone or (3) a combination of both. INF® is a manual therapy, while NVIf utilizes ultrasound guided food elimination. Outcomes include pain (Visual analog scale), sensory function (Semmes Weinstein Monofilament), physical function (Lower extremity functional scale, 10-meter walk test, timed up and go) quality of life (Norfolk Quality of life-Diabetic neuropathy), and neurovascular blood flow analysis. Study participants will be 35-85 years old with a physician-confirmed diagnosis of moderate to severe lower extremity peripheral neuropathy and at least one symptom: numbness, tingling, burning, sharp pain, or increased sensitivity. They must score 0-60 on the Lower Extremity Functional Scale (LEFS), speak and understand English, provide written informed consent, and be willing to complete all study procedures, including intervention and follow-up visits. Participants must be able to ambulate independently with or without an assistive device. Subjects will be recruited using email and flyer through the Neuropathic Therapy Center (NTC) research interest list and through providers at Loma Linda's University (LLU) Health offices. 60 subjects will be recruited, and consent will take place at the LLU or at the Murrieta study site prior to randomization, administered by trained study staff authorized to obtain informed consent.
