Comparative Effects of tDCS and tACS on Pain, Dexterity, and Strength in Diabetic Peripheral Neuropathy

This study will be to compare the effects of transcranial direct current stimulation and transcranial alternating current stimulation on neuropathic pain, manual dexterity and isometric muscle strength in diabetic peripheral neuropathic patients. Study design will be randomized clinical trial. Evaluation will be done by using McGill Pain Questionnaire-2, Digital force gauge sf-500 and wooden 9 hole peg board. Non-probability convenient sampling will be used and 38 subjects will be allocated to two groups by random allocation. Group A will receive TDCS and Group B will receive TACS. Both groups will receive hot pack, and ROM exercises of upper extremity before techniques application. Both groups will receive 20 sessions for the period of 4 weeks. Measurements of all the outcome variables will be taken at baseline and 4th week.
