Clinical and electromyographic studies in a patient with primary hypokalemic periodic paralysis

AG Engel, EH Lambert, JW Rosevear… - The American Journal of …, 1965 - Elsevier
A patient with severe primary hypokalemic periodic paralysis improved significantly on a
regimen low in carbohydrate, restricted in sodium and high in potassium. Moderate
weakness persisted in the proximal muscles and was associated with persistent vacuolation
of muscle fibers. Enlargement of the motor end-plate zone is described in this case of
primary hypokalemic periodic paralysis. Considerable weakness occurred even when
serum potassium values were within the normal range. On an isocaloric nonreducing diet …
