the results of this study may provide an easy non pharmacological modality for dealing with diabetic polyneuropathic pain. Also, the outcome of this study will guide physiotherapists to develop a new noninvasive treatment modality that may improve patient symptoms and promotes their social participation , this in turn may add to clinical role played by therapists in management of diabetic polyneuropathy. In Addition, increased knowledge of the influence of High tone power therapy on neuropathic pain

This study will be carried out on sixty diabetic male patients with polyneuropathy with ages 50-60 years . Patient will be randomly assigned to two grouos. group A will include 30 type 2 diabetic patients with diabetic polyneuropathy. Theses patients will receive High tone power therapy with Frequencies continuously will be scanned from 4096 Hz to 31768 Hz, allowing for a much higher power of up to 5000 mW to be introduced for 3 times per week, for 3 months for 30 minutes every session.

Group B :

This group will include 30 type 2 diabetic patients with diabetic neuropathy. These patients will receive TENS with applied frequencies range from 2 to 120 Hz. for 3 times per week for 30 minutes every session during 3 months of intervention.
