Here is a URL for foot cramps in Parkinson's Disease. http://pharminfo.com/pubs/msb/pd_foot.html If anyone can't get this, email me privately and I'll send it to you. just me, Marjorie In part it says: In Parkinson's disease (PD), cramping of the feet is also very common, but the cause is central rather than peripheral. Foot cramping is just one of several focal dystonias -- abnormal, sustained tightening of muscles -- that appear to be due to neurochemical abnormalities in the basal ganglia, that part of the brain involved in PD. Patients show a particular type of cramping characterized by downward clenching of the toes or inward turning of the foot. Cramping can occur throughout the day or night, and can be especially annoying when it interferes with sleep. Foot cramping is more common among those individuals whose PD affects just one side of the body. Dystonias are often mistaken for other causes of cramping or painful muscles. Some individuals with orthopedic foot problems, such as Òhammer toes,Ó are actually suffering from Parkinsonian dystonia. Patients with dystonias may be entirely unaware of any Parkinsonism; indeed, muscle cramping can precede the onset of Parkinsonian symptoms by years. There are no laboratory tests that distinguish dystonia from other causes of cramping, although a thorough neurologic examination and specialized tests should pinpoint the cause. Some dystonic features -- such as blepharospasm (involuntary closing of the eyelids) or torticollis (involuntary turning of the neck) -- are common in the general population
