various theories have been proposed for the pathogenesis of leg cramps
proposed that muscle cramps occur as a result of stimulation of the reflex arc and possibly through hyperextension of the motor neurones in any leg nerve or in the spinal cord
has also been suggested that leg cramps occur when a maximally contracted muscle is stimulated, thus shortening the muscle beyond physiological tolerance
visible fasciculations may precede and follow the cramp
this feature indicates excessive excitability of the terminal branches of motor neurones supplying the muscle
painful cramps
suggested that are painful because the demands of the overactive muscle exceed metabolic supply
results in a relative ischaemia and accumulation of metabolites
