简要总结
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.
详细描述
Study participants will be assessed on the first, second, fifth, tenth and eleventh sessions.
During the participants first and eleventh sessions participants will complete the Pain Quality Assessment Scale (PQAS), the Lower Extremity Neuropathy Scale (LENS), a vascular analysis of the Neurovascular Index (NVI) using a Philips Affinity 50 Ultrasound, and Neuropad® testing. The first session will also include completion of the Background Information form. Patients will be asked to wear loose fitting clothing and to arrive 15 minutes early to complete the informed consent documents on the first session.
Welltory App measurements to assess heart rate variability will be taken in the morning and evening the day before, the day of, and the day after each treatment session.
On the second session the patient will have:
- Electrocardiogram testing (ECG) for assessment of heart rate variability (HRV) using PowerLab+LabChart and BioAmp (AD Instruments, Colorado Springs, CO).
- Near-infrared Spectroscopy (NIRS) measurement using a Foresight Elite monitor (Edwards LifeSciences, Irvine, CA)
- Laser Doppler flowmetry (LDF) measurement using a skin surface Laser Doppler add-on for Chart/Powerlab (AD Instruments, Colorado Springs, CO).
- Welltory App measurements will be taken before and after treatment to assess for heart rate variability (HRV).
- A blood draw will be completed by a licensed lab technician to measure blood cytokine and HbA1C levels. A total of 1 1/3 teaspoons of blood will collected at this time point. The blood draw will be performed prior to treatment.
- The patient will then receive a 60 minute INF® Therapy or standard physical therapy session.
- The aforementioned tests will then be repeated including ECG, NIRS, and LDF to measure post treatment values.

盲法说明
Single-blinded study. Subjects will be randomly assigned to one of two treatment groups. Treating therapists will be informed of the study arm assignment. The physical therapist performing the pre and post evaluation measurements will be different than the treating therapists and blinded to the study arm assignment.

研究组 & 干预措施
Intraneural Facilitation Therapy Treatment Group
Subjects will receive nine 60-minute INF® Therapy Treatments during sessions 2 through 10. INF® Therapy is a non-invasive treatment that helps eliminate pain, tingling, numbness, and other symptoms that come with neuropathy.
干预措施: Intraneural Facilitation Therapy Treatment (Other)
Standard Physical Therapy Treatment Group
Subjects will receive nine 60-minute standard physical therapy treatments during sessions 2 through 10.
干预措施: Standard Physical Therapy Treatment (Other)
结局指标
主要结局
The Impact of INF® Therapy and Standard Physical Therapy on Heart Rate Variability
时间窗: Through study completion, an average of 6 weeks.
This is a composite measurement combining electrocardiogram and Welltory App measurements. Heart rate variability (HRV) is the variation in the time interval between consecutive heartbeats and can be used to assess the current state of the nervous system. HRV measures will include LF, HF, LF/HF ratio, SDNN, SDANN, RMSSD, and NN50. The calculation of these variables allows HRV to be quantified. A normal result is between 25 to 50 milliseconds while an abnormal result is less than or greater than that range.
