This technique, which I described in a previous letter,3 includes two 10-second stretches repeated 3 times daily until cramps disappear and has continued to be highly effective in our patients. Calf stretching has been widely recommended by others,4- 5 is considered to be similar to quinine in its effectiveness,4 and is preferred over quinine as first-line prophylactic therapy,5 with no cost plus greater safety and convenience.
