Study summary

This is an amendment to study posting NCT00970060. Based on preliminary results from that study is was determined there needs to be a follow-up exercise intervention study. This study has two additional aims than the original study. The objectives are to determine is a prolonged exercise routine, 16-weeks, paired with refined measures of effectiveness positively impact people with diabetic neuropathy.

What researchers measure

Primary outcomes

  1. Change nerve function

    Change in nerve function will be quantified using the Total Neuropathy Score (TNS). The TNS is a composite measure of peripheral nerve function that includes grading of signs/symptoms, nerve conduction studies, and quantitative sensory testing. We will not include proprioceptive testing in this project.

    Time frame: Baseline to Week 16

  2. Change in aerobic fitness

    Aerobic fitness will be assessed with a graded maximal exercise test as in the previous protocol with a metabolic cart and integrated ECG.

    Time frame: Baseline to Week 16

Secondary outcomes

  1. Change in cutaneous innervation

    Change will be measured after exercise intervention to see what effects exercise has on dermal and epidermal innervation. Change measured via skin biopsy.

    Time frame: Baseline to Week 16

  2. Change in maximal workload

    Measured as part of the aerobic fitness assessment. Use of standardized protocol with total body recumbent stepped to be used to obtain the maximal workload.

    Time frame: Baseline to Week 16

  3. Change in pain experienced

    Pain will be measured using the Brief Pain Inventory Short Form for diabetic peripheral neuropathy. This scale has been specifically validated in this population and consists of 3 pain severity items and a 7-item pain interference scale.

    Time frame: Baseline to Week 16
