Abstract

|
|
|
Arthrogryposis multiplex congenita (AMC) is a rare disease characterized by fixed position of multiple joints and an associated limitation of movement due to many fetal and neonatal disorders of the motor system. Multiple contractures are more common in distal joints than proximal joints and can accompany congenital anomalies of other organs. The development of fixed joints with limitation of movement is secondary to impaired intrauterine motility which is caused by muscle weakness. The basis for the weakness that leads to AMC resides at every major level of the motor system. We introduce six cases diagnosed as AMC and their electrodiagnostic findings. The first and next two cases were myopathic and neuropathic each in the electrodiagnostic evaluations. The last three cases showed normal findings.
