        | Balducci  et al. [50] | -Randomized controlled clinical trial -4 year (4h/week) exercise program in diabetes    patients without neuropathy at enrollment
 | -Significantly more cases of sensory or motor    neuropathy in the control group during the 4 years -Exercise may delay or even prevent the onset of DPN    in diabetic patients

        | Smith et al. [51] | -Individualized diet and exercise counseling in    patients with neuropathy associated with impaired glucose    tolerance (IGT) for 1 year | -Positive changes in intraepidermal nerve fiber    density (IENFD) and reductions in pain in the visual analog scale (VAS) - IENFD should be included as an    end point in future neuropathy trials.

        | Chen et al. [17] | -Randomized controlled trial with rodent model -Daily exercise training in induced diabetic mice vs    sedentary induced diabetic mice
 | -Reductions in diabetes-associated neuropathic pain,    including thermal hyperalgesia and mechanical allodynia in the exercise group -Greater expression of    Hsp72 in the exercise group

        | Kluding et al. [53] | -10-week exercise and resistance training program in    DPN patients | -Increases in IENF    branching, reductions in pain (VAS), reductions in neuropathic symptoms post    exercise program |
