Vascular Reflexes in Diabetic Autonomic Neuropathy.
Mother & Child Jan ;37(4):141-6.

The vascular responses to valsalva manoeuvre and sustained handgrip were measured in fifty diabetics with signs and symptoms suggestive of autonomic neuropathy. The valsalva manoeuvre was abnormal in forty-seven (94%) and handgrip was abnormal in twenty-four (48%) of the patients. The response to the two tests were normal In six patients with impotence alone. It Is concluded that both the valsalva and handgrip tests are useful to give an objective assessment of the state of the autonomic nervous system In diabetes.
