Study objectives	Are regular calf-stretching exercises effective in the management of nocturnal leg cramps? Nocturnal leg cramps are painful muscle spasms which commonly disrupt sleep. Their cause is unclear and they are frequently treated with quinine which is potentially toxic and costly to the NHS. In 1979 a small, uncontrolled trial suggested that a simple programme of leg muscle stretching exercises could prevent nocturnal leg cramps. This has been widely cited but no attempt seems to have been made to confirm or refute its conclusions. We intend to establish whether such exercises are effective, feasible and whether they reduce quinine use. To determine whether regular exercises are effective and feasible in the treatment of leg cramps.
