Brief Summary

This study will examine how two types of exercise programs affect nerve health in people with diabetic peripheral neuropathy. Diabetic peripheral neuropathy is a common complication of type 2 diabetes that can cause numbness, pain, balance problems, and reduced quality of life. Exercise is often recommended for people with diabetes, but it is not yet clear which types of exercise are most effective for improving nerve function. In this randomized controlled trial, participants with type 2 diabetes and confirmed peripheral neuropathy will be assigned to one of three groups. One group will perform a combined program of aerobic and resistance exercises (concurrent training). Another group will perform soleus push-up exercises, a seated ankle movement designed to activate the soleus muscle and improve glucose metabolism. The third group will continue with standard diabetes care and general lifestyle advice without a structured exercise program. The study will evaluate whether these exercise interventions influence biological markers related to nerve repair and neuroplasticity, including brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and the Schwann cell marker S100B. In addition, the study will assess changes in neuropathy symptoms, balance and postural stability, blood sugar control, and quality of life. Participants will complete assessments before the intervention and again during follow-up after the exercise program. The findings of this study may help identify effective and feasible exercise strategies to support nerve health, improve physical function, and reduce the impact of diabetic peripheral neuropathy.

Outcome Measures

Primary Outcomes (3)

  • BDNF (Brain-Derived Neurotrophic Factor)

    Serum Brain-Derived Neurotrophic Factor (BDNF) concentration will be measured quantitatively using a commercially available enzyme-linked immunosorbent assay (ELISA) kit at baseline, 4 weeks, and 8 weeks. BDNF is a neurotrophic factor involved in neuronal survival, synaptic plasticity, and exercise-induced neuroplasticity. Changes in circulating BDNF levels will be used as a primary biomarker of exercise-induced neuroplasticity and neurogenesis-related biological activity. Higher serum BDNF concentrations are considered indicative of greater neurotrophic activity and potential enhancement of neuroplastic processes.

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • NGF (Nerve Growth Factor)

    Serum Nerve Growth Factor (NGF) concentration will be measured quantitatively using a commercially available enzyme-linked immunosorbent assay (ELISA) kit at baseline, 4 weeks, and 8 weeks. NGF is a key neurotrophic factor involved in the survival, maintenance, and regeneration of peripheral neurons. It plays a fundamental role in peripheral nerve repair and axonal regeneration following nerve injury. Changes in circulating NGF levels will be used as a primary biomarker of peripheral nerve regeneration and neuroregeneration-related biological activity. Higher serum NGF concentrations are considered indicative of enhanced neurotrophic support and regenerative potential of peripheral nerves.

    From enrollement to 4 weeks and then after 8 weeks of intervention

  • S100B (Schwann Cell Marker)

    Serum S100 Calcium-Binding Protein B (S100B) concentration will be measured quantitatively using a commercially available enzyme-linked immunosorbent assay (ELISA) kit at baseline, 4 weeks, and 8 weeks. S100B is a calcium-binding protein that is expressed by Schwann cells in the peripheral nervous system and plays an important role in peripheral nerve repair, remyelination, and axonal regeneration. Changes in circulating S100B levels will be used as a primary biomarker of Schwann cell activity and peripheral nerve regeneration. Higher serum S100B concentrations are considered indicative of increased Schwann cell-mediated neuroregenerative activity.

    From enrollment to 4 weeks and then after 8 weeks of intervention

Secondary Outcomes (8)

  • Michigan Neuropathy Screening Instrument (MNSI)

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • Vibration perception threshold (VPT)

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • Balance and Gait Mobile Application

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • Glycated Hemoglobin (HbA1c)

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • Norfolk Quality of Life-Diabetic Neuropathy (QOL-DN)

    From enrollment to 4 weeks and then to the end of treatment at 8 weeks.

  • +3 more secondary outcomes
