Diabetic Peripheral Neuropathy | Other: A computer based cognitive rehabilitation program (Rehacom system) Device: Vagus nerve stimulation | Not Applicable |
This research aims to
- determine the effect of non-invasive Vagus nerve stimulation on cognitive functions in diabetic peripheral neuropathy.
- investigate the correlation between cognitive function and severity of diabetic neuropathy.
- investigate the correlation between cognitive function and quality of life in diabetic peripheral neuropathy.

Other: A computer based cognitive rehabilitation program (Rehacom system)
Rehacom cognitive rehabilitation software will be used to treat the cognitive dysfunction
Device: Vagus nerve stimulation stimulation will be applied on cymba conchae of left external ear. A stimulation of frequency of 20 Hz, pulse width of 200 - 300 Ms and intensity of 0.5 mA. The stimulation will be on for 30 s and off for 48 s.The stimulus duration will range from 20 to 40 min. |
- Attention/ concentration score [ Time Frame: at baseline ]Rehacom will be used to assess score of attention/ concentration domain of cognitive function
- Attention/ concentration score [ Time Frame: post intervention (after one month) ]Rehacom will be used to assess score of attention/ concentration domain of cognitive function
- working memory score [ Time Frame: at baseline ]Rehacom will be used to assess score of working memory domain of cognitive function
- working memory score [ Time Frame: post intervention (after one month) ]Rehacom will be used to assess score of working memory domain of cognitive function
- Executive function score [ Time Frame: at baseline ]Rehacom will be used to assess score of executive function domain of cognitive function
- Executive function [ Time Frame: post intervention (after one month) ]Rehacom will be used to assess score of executive function domain of cognitive function
