This paper reports the case of an 11-year-old girl with painful pes cavus feet. The pain has diurnal fluctuation of symptoms; it is minimal after sleep and becomes more severe in the afternoon or evenign everyday, especially after walkign for long distances. Clinically, the child's feet had pes cavus deformity with hypertonia of the distal lower limbs. Radiological studies of the feet and the spine yielded essentially normal results. Diagnosis of Segawa disease was made in view of the diurnal fluctuation of symptoms that responded to dopa drugs. Both the foot pain and abnormal tone improved after drug treatment.
