Risk Perception Intervention for High-Risk Diabetic Foot

This study aims to evaluate the effect of health education based on information framing effects on foot ulcer risk perception in patients at high risk of diabetic foot. Study Design: A randomized controlled trial with three groups: Experimental Group 1 (Gain-Framed): Participants received a benefit framing message that emphasized the benefits of standardized foot care in reducing the likelihood and severity of foot ulcers, with an aim to reshape patients' perception of risk. Experimental Group 2 (Loss-Framed):Participants received a loss frame message that emphasized that neglecting foot care would increase the likelihood and severity of foot ulcers. The message was designed to awaken patients' awareness of crisis and risk perception. Control Group (Routine Messaging):Participants received the usual content of care in the endocrinology department without a specific framework. Participants: Diabetic foot patients at high risk from experimental group 1, experimental group 2, and control group 3. Inclusion criteria included adults with a diagnosis of diabetic foot at high risk. Intervention: The Total Study Period consisted of an intervention phase and a follow-up phase. The intervention phase started at the time of enrollment and lasted until the fourth week after discharge. The follow-up period lasted for 3 months. Data on local indicators were collected at baseline/before the intervention (T0), immediately after the intervention (T1), 1 month after the intervention (T2) and 3 months after the intervention (T3). Outcome Measures: Primary Outcomes: Foot ulcer risk perception: Assessed using The Tripartite Model of Risk Perception Scale. Secondary Outcomes: Foot care behavior score: Assessed using The Nottingham Foot Care Assessment Scale; Self-efficacy: Assessed using The Diabetes Self-Efficacy Scale; Intention to delay seeking medical help score:Assessed using the Questionnaire on Intention to Delay Seeking Medical Care for Patients with High-Risk Diabetic Foot; the incidence/recurrence rate of foot ulcers, and various laboratory indicators.

Wearable Sensory Prosthesis to Improve Coordination, Walking, and Physical Activity

The goal of this clinical trial is to investigate whether sensory stimulations from a neuroprosthesis device (Walkasins®) can increase physical activity and improve gait quality in persons with peripheral neuropathy (PN). The main question it aims to answer is whether Walkasins enhances habitual activity patterns in adults with peripheral neuropathy. Participants will do the following as part of the study: * Complete a sensation and balance assessment to determine eligibility for the study. * Answer questions about their medical history, physical function, balance confidence, and sleep. * Perform various balance and walking tasks on three separate occasions. One of the tests involves walking for six minutes without a cane or walker. * Wear an activPAL activity monitor for ten days on three separate occasions and return it to the researcher as directed. * Wear Walkasins for ten weeks as part of their daily routine. Walkasins consists of two parts: 1) an insole that fits inside the shoe and 2) a strap that secures around the ankle.

The Treatment of Painful Diabetic Neuropathy With Diet

The purpose of this clinical trial is to determine whether targeted nutritional changes can improve symptoms of painful diabetic neuropathy. Impaired blood flow to peripheral nerves-resulting in reduced oxygen delivery and subsequent nerve injury-is a well-established contributor to neuropathy. Prior studies have shown that a whole-food, plant-based diet without added oils can improve or even reverse arterial disease, suggesting a potential mechanism for enhancing nerve perfusion and function. This study is a randomized controlled trial comparing a whole-food, plant-based diet with standard pharmacologic management for painful diabetic neuropathy.

Balance4Mobility: Effects of Walkasins Use in Individuals With Peripheral Neuropathy and Balance Problems

The goal of this clinical trial is to is to test whether Walkasins can help people with peripheral neuropathy maintain their balance better. The main question it aims to answer is whether participants who use Walkasins on an everyday basis over a six-month period will report better awareness of their foot placement on the ground. Researchers will compare Walkasins users to a control group of participants who are not using Walkasins to see if the device improves the users' performance on some standing and walking tests. Control group participants will get Walkasins after six months of being in the study. During the study participants will be asked to do the following: * Answer questions about their medical history and balance. * Do some standing and walking tests. Some of the tests will be timed. * Attend study visits and participate in study phone calls. * Keep track of any falls and notify study staff if they fall. * Wear the Walkasins device on a regular basis.

A Physiologic Comparison of Two Approaches to Treating Peripheral Neuropathy

Diabetic peripheral neuropathy is one of the most common and costly microvascular complications of diabetes impacting more than 50% of patients and costing more than 10.1 billion dollars annually. Intraneural Facilitation Therapy (INF® Therapy) is a non-invasive technique that has shown to improve balance and pain in patients with Type 2 Diabetic Peripheral Neuropathy (T2DPN); however, the underlying physiological mechanisms need further understanding. The purpose of this study is to investigate the physiological mechanisms behind two approaches to treating T2DPN, INF® Therapy and standard physical therapy. Eligible subjects presenting with diabetic neuropathy symptoms will be recruited and referred to the Loma Linda University Health's Neuropathic Therapy Center. Forty patients will be evenly randomized into two groups: an INF® Therapy Treatment group and standard physical therapy treatment group. Subjects will participate in 11 study visits over a period of 6 weeks. Non-invasive assessments will measure neuropathy pain, heart rate variability, neuropathy severity, blood oxygen levels, and blood flow under the skin. Lab draws will measure inflammation levels in the blood and how well blood sugar levels have been maintained over a period of about 3 months. Descriptive statistics and repeated measures ANOVA will be used to analyze data and answer the research questions. The findings of this study will provide a better understanding of how INF® Therapy and standard physical therapy work, subsequently improving non-invasive treatment methods for T2DPN patients.
